| 2026-09-11 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | Cloudless except for distant Cb on ESE horizon and a pattern of Cs that looked like a translucent hand stretched across the sky after 21:00. Very warm and dry. |
| 2026-09-10 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | Nice displays of Cc and other cirriform clouds. Transitioning late in the afternoon to Ac and some Cs. On its edges, the Ac trails off into Cc and Ci. Totally cool. Otherwise clear, relatively cool, and dry. |
| 2026-09-09 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | Scattered Ac and higher clouds early. Cu start forming over the foothills by 10:30. Midafternoon a line of storms forms south of us and moves NE. Some Cu con develop in the foothills closer to us but dissipate as they move east. |
| 2026-09-08 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | Broken Sc and Sc cast with some virga. Middle level clouds above that. By 13:00 flocks of Cu and Cu con develop N, S and foothills under deck of As and Ac. 16:30 rain clouds SE, S, SW. TS to SE. 17:07-17:12 short sprinkle but nothing measurable. |
| 2026-09-07 | 7:44 AM | 0.08 | NA | NA | NA | NA | | At first, convection seems limited to the foothills. Cu march across the south sky but nothing like yesterday. Then there’s some isolated storm development along the foothills midafternoon including one SW of us but it dissipates. More convection later in afternoon including a TS at 16:45 to the W with sprinkles at 17:03. It’s mostly virga and the center of the TS passes N of us. By 17:50 it has dissipated but nice Cb development to E and we can see rain falling somewhere between Brighton and Ft. Lupton. Radar confirms this and shows rapid expansion. Some more virga producing clouds appear to our W. Then we see lightning to the SW starting about 20:00 but there are only small radar echos, so when a TS appears out of the SW at 20:55 with sprinkles of large drops about 20:58 and moderate rain 21:05 to 21:15, we are surprised but thankful. More lightning appears SW and W and periods of light rain occur at 21:52, and 22:20 to 22:35 before it starts to clear. |
| 2026-09-06 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | Two moisture patterns. One with Cu to the south swings out east and to the far NE. The Cu grow all day ultimately into some Cb that give us a nice light show on the horizon until late evening. The other features various cumuliform clouds along and near the foothills. Not much growth that we can see except dark clouds to our SW that approach with virga late afternoon but only give us wind as they blow out and dissipate. |
| 2026-09-05 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | Not many clouds most of Friday save Cu to the south. Then a few Cu con north and south. Suddenly late afternoon a bunch of Cb pop up over the foothills, glaciate, and just as quickly dissipate producing only virga. |
| 2026-09-04 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | A row of Cu hung over the foothills early Thursday morning and banks of Cs and Cc crisscrossed the sky about 10am but most clouds were gone by 11:30. A few Ac or Cu pop up during the day but it is hot and dry. |
| 2026-09-03 | 7:00 AM | 0.01 | NA | NA | NA | NA | | A cloudless sky greets us this morning. Eventually Cu humulis (hum) form over the foothills. They don’t get more than about 3-5 miles east, and they grow to Cu con only over the foothills and after noon. A few glaciate. 16:45 TS with at least virga to W and SW surprises us. 16:54 sprinkles big drops. Moderate rain with winds up to 25 mph. Ends about 17:15. |
| 2026-09-02 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | Early As cloud cover moves east and clears with Cu over the foothills that flatten as they too move east. During the afternoon Cu continue to form but don’t grow much except a few Cu con out east. Nothing becomes of them as they evaporate. |
| 2026-09-01 | 7:32 AM | 0.05 | NA | NA | NA | NA | | The day starts overcast again with As and a few Ac. There is a bank of what looks like a glaciated Sc with virga to the north. A mix of middle and some lower clouds pass through all day. Finally some Sc and storm clouds approach from the SW with rain in the foothills. We get some light rain for a few minutes at 18:55 and moderate rain with moderate breezes at 20:50 tapering off after 15 minutes. There may have been more overnight because the gauge read 0.04 at 9pm. |
| 2026-08-31 | 7:23 AM | 0.08 | NA | NA | NA | NA | | Overcast with As and a few Cu at sunrise. The Cu flatten out into a layer of Sc about 09:00 and thin out as they move east. Several more banks of Sc move through. Then unexpectedly a line of showers moves through, preceded by moderate wind, then moderate rain starting at 13:05, which diminishes to light rain by 13:11 and ends by 13:21. Radar shows waves of monsoon showers moving from west. 14:07, 14:30 sprinkles again. TS to SE. But no real repeat of the earlier shower. More showers approach on radar about 10pm but they turn into wind. |
| 2026-08-30 | 7:45 AM | 0.03 | NA | NA | NA | NA | | Mostly overcast with banks of As and Ac and some Cu most of morning and afternoon. Hot dry wind much of the early afternoon. Starting 15:11 line of TSs bring moderate wind then a few minutes of light to moderate rain and wind in several spurts lasting until 15:31. They leave behind a bit more than 0.03”. Much more is needed! |
| 2026-08-29 | 7:30 AM | T | NA | NA | NA | NA | | Mostly clear early with mixed middle level clouds which persist into the afternoon and isolated Cb develop primarily NW. Breezy and very hot. Up to 97 with dp of 48 making for very high cloud bases. AT 15:00 virga E. Dark clouds approach from NW accompanied by strong winds but no rain until they’ve mostly passed and we get intermittent light rain at 15:30 that leaves a trace. More virga later but eventually all promise of ran evaporates. |
| 2026-08-28 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | Some Sc castellanus to the south at 08:30. Cu grow and fizzle, following the usual pattern including a 15:30 sprinkle which left the gauge dry. At 17:00 there are distant isolated Cb at various stages in 4 directions plus Sc and Cu con overhead and to the W. Some pretty clouds and a partial rainbow in the virga but nothing measurable here on the ground. |
| 2026-08-27 | 7:49 AM | T | NA | NA | NA | NA | | An almost cloudless morning greets us. Cu form over the foothills. By 12:30 Cu con are growing vertically very quickly but a strong shear curtails some cloud development. Mid afternoon a small TS passes nearby. At 16:53 a sprinkle moistens the walkways and leaves a trace even smaller than yesterday’s. This is frustrating. |
| 2026-08-26 | 7:40 AM | T | NA | NA | NA | NA | | Sky full of Sc, As and Ac greet the day. By noon the west sky over the foothills is filled with Cu con. By 13:00 many have either dissipated or glaciated into virga yielding cells. 14:00 and 15:00 two nearly dry TSs pass, leave a few drops and the sky starts clearing except for a few isolated storms including a big one near Grover. |
| 2026-08-25 | 7:30 AM | 0.00 | 0.0 | NA | NA | NA | | We saw Ci and Cc early to mid morning. Around noon Cu started growing over and near the foothills possibly aided by lifting from 15-30 mph E wind. By 15:30 there were several potential storm clouds including one TS NW of us with virga. All afternoon everything seems to go around us. There were some nice mammata S of us from the storm near Boulder, which around 18:00 started to blow out, sprinkling us for about 20 minutes with a 15-20 mph breeze. However, it left nary a drop in the gauge. |
| 2026-08-24 | 7:26 AM | T | NA | NA | NA | NA | | High and middle level early clouds mostly replaced by isolated Cu con and some Cb over the plains as early as 13:30. TS towards or past Berthoud and another far SE. TS, sequence of short 1-3 minute showers with light rain large drops. 14:58, 15:18, 15:31, 15:48. Another mostly spent storm rolled down from the hills but barely sprinkled. So much potential, so sparse the result. |
| 2026-08-23 | 7:47 AM | 0.01 | NA | NA | NA | NA | | Clear except high clouds early. Then foothill Cu which start growing after 10:30 but they glaciate at rather low elevations into Ac and As and start showing some virga. It’s cooler than Friday at 83° and rather humid with 63° dp at 13:45. Storm development continues to arrest here and in the foothills as of 16:30 with scattered virga and light sprinkles. But NE and SE it’s really booming. 17:30 Foothills “storms” devolved into banks of Ac. SE Cb is now a severe TS. 19:06 TS approaching from W. But IT disappeared. Then yet another TS appears to the W but just grazes us but rains all the way into Longmont. |
| 2026-08-22 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | Clear early. Very hot. A few Cu over foothills and plains by 10:00. Gradually grow to Cu con and Cb with virga by 15:00. Small cell to W and N. 15:50 TS with virga to S. Nothing here. Storms and clouds gradually pass and dissipate. Only a small spider in the gauge! |
| 2026-08-21 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | A few mid-level clouds early. Then isolated Cu. The only clouds growing as of 2pm are far south perhaps Colorado Springs and beyond where there are some real boomers! They continue all afternoon, but Cu over the foothills here never make it to the plains. |
| 2026-08-20 | 7:58 AM | 0.06 | NA | NA | NA | NA | | Ac early then a bank of Sc cover western sky but move on by 10am. By 11:30 Cu growing along foothills. At 14:10 TS near Lyons but it doesn’t touch us. At 16:17 there’s the first of several short sprinkles. Then at 17:51 a TS with light to moderate rain and at 17:58 we hear some hail hitting the windows for about 30 seconds. However there may be only one pea sized dent on the hail pad but I can’t make it out in the morning. Relatively little wind. Rain tappers off a few minutes after 6pm. Interesting that this monsoon rain came as a string of cells from the NW. All the recent traces came from the SW. |
| 2026-08-19 | 7:00 AM | T | NA | NA | NA | NA | | Cc and some Ac early, then Cu and Sc mid morning. The sky keeps changing, clouding over at noon with Sc, then these move east and dissolve, to be replaced by others. Finally as an apparent front moves through we have a sprinkle at 9:05 pm and another as a TS passes just N of us about 11pm. I guess this month “TS” stands for “Traces.” |
| 2026-08-18 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | Early Cu over the foothills grew out, sometimes up, but all eventually petered out, dissipating into Ac as they moved out over the plains. |
| 2026-08-17 | 7:34 AM | T | NA | NA | NA | NA | | 7am and fog with some low Cu. By 9am, clear except Cu over foothills. Cu start growing by 11am but break up into fragmenting Sc then Ac as they float over the plains. By 1 pm, Cb and Cu con to the NW. Isolated storms come and go. Sometime after 6pm, with TS just SW and just N of us, we get some drops. I didn't think it was measurable, but enough fell in the gauge to make a trace. We are more than half-way through the month and we've only had 0.15" plus some traces. Normal for August is 1.71 based on ClimGrid. |
| 2026-08-16 | 7:39 AM | 0.04 | NA | NA | NA | NA | | At 9am, Cu over the foothills and banks of Ci, Cc, and very high Ac and As. Humidity relatively high with 61° dp and air temperature of 75. Cu growing rapidly at 10 and spread out at 11:15. By 13:00 Cb north and south. Finally a 16:45 sprinkle and a very active TS to WSW west of gold hill. Might get here or hit Lyons instead. 17:15 light rain. Little wind. 17:25 a bit more wind. 17:34 close to moderate rain on back end of cell. 17:55 rain ends. Rainbow. |
| 2026-08-15 | 7:32 AM | 0.02 | NA | NA | NA | NA | | The day started with low lying Cu and some scattered Ci. Cu were growing by noon and quite suddenly the sky was full of not very well organized clouds by 2pm as I headed to the optometrist in Boulder. By the time I emerged at 3 there was light rain all the way from Boulder home, and light showers continued into the evening. Yet again it only amounted to 0.02”. The eastern plains seemed to have all the fun. |
| 2026-08-14 | 7:48 AM | 0.02 | NA | NA | NA | NA | | Thursday started with Ac and broken Sc, the Ac thickening as the morning went. Cu started growing after noon. At 2:30 a TS passed to our south. But nothing here until very light rain at 4:41 that lasted perhaps 25 minutes. It was the first of several light showers, ending with one at 6:45 pm. There were some real boomers growing out east but we needed to be satisfied with 0.02” |
| 2026-08-13 | 7:40 AM | T | NA | NA | NA | NA | | Cirrus early. Then As and Ac
11:30 am Cu growing over mountains
1pm mature Cb to SW. Dissipated remnants S of us. Another storm N of us. 5:45 pm TS over foothills and mountains but as they approach plains they dissipate. 18:43 sprinkle. Off and on very light showers as weak cells move through. They leave us a trace. |
| 2026-08-12 | 7:05 AM | 0.05 | NA | NA | NA | NA | | Ac early. Some Sc.
Storm clouds over mountains
15:30 virga to west. TS to the west.
15:51 light rain 15:53 moderate to heavy. Wind 25-30. 16:00 rain dissipates to light but winds continue. No hail. Heavier rain now to S.
Experience does not match radar. At 16:09 radar says we are inside most intense rain, but visually it appears to have been at least 1-1.5 mi SE. Rain tappers off by 16:15. |
| 2026-08-11 | 7:13 AM | T | NA | NA | NA | NA | | Mostly cloudy early with Cu. Sc. Ac. Some virga developed with a light sprinkle that left a trace at 11:15. A bit more about 12:30. Then a drying trend, and it starts to clear, leaving only Cu. Some grow a bit but nothing more comes of it. |
| 2026-08-10 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | Mostly overcast on all levels most of the day. Early evening virga to the west. But no moisture on the ground here. Smoke persists but AQI better. |
| 2026-08-09 | 7:00 AM | T | NA | NA | NA | NA | | Hot, very dry, and smoky. With a temperature of 100F , RH of 14% and dew point of 44F, I wouldn’t imagine any rain. Scattered Cu seen from 10:30, which didn’t seem to grow, but then at 2:35 pm we had a light shower, more at 4:25 and 4:39. But the total catch was still less than 0.01”. No thunder, mostly virga, but some hit the ground. |
| 2026-08-08 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | Hot and smoky again. But “only” 95. A few scattered Cu if you could see them through the shroud. |
| 2026-08-07 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | Hot, dry, sunny, and smoky. |
| 2026-08-06 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | A cool morning began with dew and a thick cover of Sc which eventually broke up into Cu which dissipated as the day warmed up. No rain. Such a waste of water vapor! |
| 2026-08-05 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | Early Sc become Ac as temperature rises, eventually dissipating. Scattered Cu. Some grow in mid-afternoon to Cu con and glaciate. We experienced some light rain in Lyons during a drive to Estes Park, but no rain reached us. The cool temperatures were a welcome relief, but the smoke from remote wildfires persists. |
| 2026-08-04 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | Wind from front and dry storms most of the afternoon. Growing Cu but a clear view of the sky was obscured by wildfire smoke. Hot again. AQ of 101 plus temperature of 103! Misery index of 204, I guess. At 4:50 a TS to the east over Longmont and a sprinkle here. 6:20, another TS to the SE. Looks mostly virga. Perhaps some hit the ground. Here a big fat zero. |
| 2026-08-03 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | Nearly cloudless and terribly hot all day until it gradually clouded up and became overcast during the evening. Wildfire smoke moved in. |
| 2026-08-02 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | Barely a cloud in the sky. I was out working in the pasture and it felt plenty hotter than 95 degrees! 0.98” for the month of July. Better than June but still 0.85” short of 30-yr climgrid mean for our location. Condition report coming soon. |
| 2026-08-01 | 7:53 AM | 0.02 | NA | NA | NA | NA | | The atmosphere must have been dry but unstable yesterday because three small TS’s marched through. Clear at 10. Cu growing by 10:45. Then TS’s each with sustained but light rain at 1:25, 2:45, and 5:35, each yielding less than 0.01” but cumulatively 0.025”. They lasted 15, 10, and 5 minutes respectively. |
| 2026-07-31 | 7:18 AM | 0.04 | NA | NA | NA | NA | | Ac early, then Cu by noon. Suddenly Cu con were popping up by 2:00 pm. The first sprinkle arrived at 2:30. Some of the clouds grew to Cb's and at 2:55 pm or so I was caught in the veggie garden by a TS with moderate rain, which started to dissipate to light rain by 3:00. It was done by 3:03pm. A stronger storm passed north of us into Longmont. Eventually the storm clouds evaporated into Ac, where we started. |
| 2026-07-30 | 7:31 AM | T | NA | NA | NA | NA | | Clear and sunny early. Clouds start growing 10:00 to 10:30 am, glaciate, and quickly cover the sky with low-to-high level clouds. I was not home, but radar indicated light rain at about 2:15 pm. There were more sprinkles at 4:15. Only a trace was squeezed out of all those clouds! |
| 2026-07-29 | 7:23 AM | 0.22 | NA | NA | NA | NA | | Clouds grew early and produced early. By 11:45 am there was a TS to the SW near Boulder. Light rain fell at 1:45 from another TS, moderate starting at 1:50, and heavy with some scattered dime size hail until 1:54. Light after 1:58 as the storm moved E. It was done by 2:05 except sprinkles. Winds were light during the storm. 0.22" fell. There were stronger winds from another TS to the north that elicited warnings from NWS. As spent Sc passed through there were sprinkles at 2:45, 4:25, and 7:10, but only a T more rain fell after the first storm, which appeared to merge with the cell which moved from Pinewood Springs to Lyons and Longmont. Beautiful Cb and wall of rain visible. Evidence of some pea +/- size hail on the hailpad. |
| 2026-07-28 | 7:22 AM | 0.01 | NA | NA | NA | NA | | 3:48 pm TS left only a T. Another TS passed just N of us at 8:35 and left another sprinkle. Dissipating mountain storms filled out the meager 0.01" with very light steady rain 9:40 to 10:15 pm. That was all we got from vigorous cloud growth all day. |
| 2026-07-27 | 7:12 AM | 0.00 | 0.0 | NA | NA | NA | | Clouds and not as hot but no rain until an unmeasurable sprinkle just before 7am. Nothing in the gauge. Hoping for more soon. |
| 2026-07-26 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | Thankfully clouded up late afternoon but no rain. Just heat. Lots of it! |
| 2026-07-25 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | Growing clouds all day. Cloudy with thunder in the afternoon about 4:40 but unmeasurable. |
| 2026-07-24 | 6:59 AM | 0.04 | NA | NA | NA | NA | | Sc and Ac much of the day with Cu con and isolated Cb. A 3:40 unmeasurable sprinkle at 3:40 and possibly other times. A strong TS hits Longmont at about 8:40. An accompanying cell gives us 10 minutes of moderate rain with some big drops at 8:45. No hail. |
| 2026-07-23 | 7:21 AM | 0.01 | NA | NA | NA | NA | | Just under 0.02" overnight after a day in which isolated TS's over the mountains developed early and had completed their lifecycles by mid-afternoon, spreading clouds over the western half of the sky. Unmeasurable sprinkles fell from the remnants at 3:30pm, 5:30, and later, but it mostly cleared except for high clouds until the overnight shower. |
| 2026-07-22 | 7:46 AM | 0.40 | NA | NA | NA | NA | | Hooray! Real rain! After morning Ac to the south, isolated storms or Cu con appear over the mountains in mid-afternoon. Only a line of Cu stretch over the plains east from a mountain storm to the south, otherwise hazy and cloudless. A TS moves NW from Boulder to Longmont, with heavy rain to our E and something developing to our S. Sprinkles start here at 7:37 with a light rain of large drops at 8:04pm, then moderate to heavy rain 8:06 to 8:11. Moderate for another 3 minutes, then light rain tapering off quickly after 8:14. No hail. Winds 5 to 20 mph during storm. |
| 2026-07-21 | 7:27 AM | 0.06 | NA | NA | NA | NA | | Growing storm clouds over the mountains but over the plains only cumuli pop up mid afternoon. A Cb to the NW spreads out over the N and NW sky but brings only wind. The plains Cu start to grow later but mostly flatten out into Sc and Ac, but storm clouds remain N and NW. After dark some lightning very far north, perhaps Cheyenne area, but only Ac nearby. Awoken at 3:45am by steady light rain which lasts until 4am. I'm guessing the residual moisture from those clouds to our NW got new life when a cold front moved in from the NE. Hooray for the moisture. |
| 2026-07-20 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | A bank of cumulus congestus and cumulonimbus hovered over the mountains most of the day, dissipating with their altocumulus and other remnants finally moving out over the plains in the evening. We stay hot as Hades and dry as a bone. |
| 2026-07-19 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | More heat. No relief! A line of clouds stretch out east south of us, probably east of Boulder or Eldorado late in the day. Otherwise mostly cloudless. |
| 2026-07-18 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | Storm clouds grew quickly and topped out over the mountains and foothills after noon, but dissipated. Some cumulus ventured out onto the plains, but as the day progressed all dissipated except for a few stratocumuli at sunset which also soon evaporated, along with hopes for a monsoon flow. Maybe next week. |
| 2026-07-17 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | A whole bunch of cumuliform clouds, some growing as the day progressed. Looked like a shower south near Boulder. At 8:45pm we got a few drops from a passing dissipating Cu con. Nothing measurable. |
| 2026-07-16 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | Continued hot and dry with afternoon winds. Yesterday we started to see an increase in clouds. Cumulus, numerous, flat and spread out but not quite stratocumulus. Perhaps a harbinger of monsoon moisture? |
| 2026-07-15 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | More sun and heat. Few clouds. Breezy in the late afternoon. |
| 2026-07-14 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | More sun. More heat. |
| 2026-07-13 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | Sunny, hot, and dry! |
| 2026-07-12 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | A dissipating Cu con with virga and downburst generated strong winds for about 15 minutes at 5:35pm but no precipitation. |
| 2026-07-11 | 7:34 AM | 0.04 | NA | NA | NA | NA | | TS's growing over foothills, one cell S of Jamestown at 4:22. Starts sprinkling 4:33 pm, then intermittently light rain at 4:35 with wind 20-25 gusting higher at times. Rain intensifies to moderate at 4:47 but for only 1 minute, mostly done by 4:50. Radar showed us on the edge of the rain as late as 4:56 but it had moved on. No hail. |
| 2026-07-10 | 7:45 AM | 0.16 | NA | NA | NA | NA | | Hooray! Rain came in 2 or 3 periods from two storms. Sprinkles at 1:28pm. TS and light rain 2:05 to 2:15 pm. Lots of cloud-to-cloud electricity in cell to our south. Large drops at 2:31, light rain for 2 minutes at 2:39 with some sprinkles later. Gauge read 0.01 at 3:16 pm. Second group of Tstorms approach from west. 4:18 TS with light rain and wind 4:21 moderate, wind 20-35 mph. Subsides to light at 4:34, wind 10-25 mph. Sprinkles after 4:41 and done by 4:45. 0.15 in second storm. No hail. |
| 2026-07-09 | 7:00 AM | T | NA | NA | NA | NA | | As early as noon cumulus were growing and blowing out to virga. Then some clouds started popping out east. By 1:30 everything west of Longmont was overcast and threatening. TS overhead gave us 1 minute of light rain at 3:19pm but quickly moved east. TS all around, also moving east. By 4-4:30 it was clear with scattered clouds. |
| 2026-07-08 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | Once again, several nearly dry TSs pass over or near, with light sprinkles, at 2:30pm, 3:45, 4:35 (for 20 minutes), and 5:35, but the gauge is bone dry. |
| 2026-07-07 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | Haze, middle and high level clouds but no rain |

| 2026-07-05 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | Cumulus started growing early afternoon. We could see an hear a TS pass south of us, but nothing here. Clouds mostly cleared in time for the man-made fireworks. |
| 2026-07-04 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | Happy 4th and 250th! Cumuli started growing early afternoon but didn't afford much shade. They also didn't produce any fireworks or rain here. Maybe today! |
| 2026-07-03 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | Fair, very warm, dry, and still hazy from the fires. |
| 2026-07-02 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | A single isolated TS with plenty of electricity passed to our NW, moving from Ward to Pinewood Springs NW of Lyons and beyond about 10-11pm. We could also see some boomers to the NE. We had nothing here. |
| 2026-07-01 | 7:24 AM | T | NA | NA | NA | NA | | Not quite 0.01”. Three sprinkles at 4:33, 6:43, 8:53. Most in a 3 minute burst of light rain at 4:33 as a line of cells march from SW to NE in a monsoon pattern although NWS only mentions a shortwave trough and moist air flowing from Baja and the Gulf. Haze continues from the fires. |
| 2026-06-30 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | Another very warm and dry day. Smoke and haze from regional fires dissipated somewhat and winds changed. Nearly cloudless yesterday. |
| 2026-06-29 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | Warm and dry continues with smoke somewhat less with the passage of a cold front and shift in winds. |
| 2026-06-28 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | Warm and dry. Small cumulus dominated most of the day. High clouds and possibly high elevation smoke haze moved in toward sunset. Smoke from Utah fires blew in about 10:30pm. |
| 2026-06-27 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | Lots of growing cumulus in the afternoon, some glaciated clouds south and east going to virga. Looked like some fell quite far south of us. No precipitation here. Strong westerly winds after 10:30pm. |
| 2026-06-26 | 7:52 AM | 0.06 | NA | NA | NA | NA | | Rain arrived in 3 intervals yesterday. Somewhat more than 0.02" of light rain continued for 45 minutes after servicing the gauge. A bit less than 0.01" at 11:45am. The remaining 0.03 at 8:10pm for only 10 minutes of light to moderate rain on the edge of a strong TS passing through Longmont. Again, we missed most of the fun. From our location we could see the 8pm storm as an opaque wall of rain and perhaps more moving across Longmont. Another string of cells that hit Boulder formed over us and to our SW but headed SSE. Thankful for any moisture we get. And thankful for no hail. |
| 2026-06-25 | 7:01 AM | 0.04 | NA | NA | NA | NA | | Rain during at least two periods: light rain from a TS at 12:22am and light rain before servicing the gauge at 7:00am. Duration of each unknown. Awaken by TS at 12:22am and rain continued for about 5 minutes. Raining when waking in the morning at about 6:45 and continuing until a few minutes ago, about 7:45am. Overcast most of June 24. A light insubstantial sprinkle at 3:55pm. Rain clouds accumulated after 8:30pm but we missed most of the action, with lightning north of us at 8:55pm but rain avoiding us until after midnight. No hail. |
| 2026-06-24 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | High and mid-level clouds most of the day and an evening severe storm watch, but the only storms were out on the eastern plains. Then a tiny sprinkle at 11:50 pm that amounted to nothing in the gauge. |
| 2026-06-23 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | Cumulus clouds grew, glaciated, and dissipated most of the day, perhaps resulting in something out east, but here all we got was a sprinkle at 1:38pm without leaving measurable moisture. |
| 2026-06-22 | 7:05 AM | 0.07 | NA | NA | NA | NA | | Unexpected TS 9:40pm moved in from the mountains after a day of cumulus passing over growing and clearing in waves, moving east to grow into storms there. Moderate rain until 9:55 then light and finally only sprinkles after 10:20pm. No hail. |
| 2026-06-21 | 7:00 AM | 0.00 | 0.0 | NA | NA | NA | | After sunny start to Saturday, cumulus congestus start to form at 11am. Spinkles felt at 12:45 and 1:45 pm. Nothing caught in gauge. |

Smoke from the South Fork fire near Harrison NE blew in around midnight. Wetness of pavers and plants suggests rain in early morning. Radar showed a bank of light rain or drizzle over us between 4:30am and 6:00am. Rain apparently cleared out smoke. |

| 2026-05-30 | 7:29 AM | 0.03 | NA | NA | NA | NA | | We were on the N edge a strong TS moving SW to NE from Boulder. Beautiful display of mammatus N of TS to our W. 3:52 pm light rain, heavier (now moderate) at 4:14 until 4:35. Light rain off and on until at least 5:10 |
| 2026-05-29 | 7:28 AM | T | NA | NA | NA | NA | | Storms all around us and thunder above, but all we got were big drops about 6pm and a light sprinkle at 10:30pm, all for just a trace. |
