If it's going to be this gloomy, it might as well rain right? Stuck in the shadow of the Palmer Divide today, Denver and Boulder are fighting for a few scrappy showers. This fight will continue through the evening #cowx

Nice to see SE Colorado get some beneficial moisture today! They missed out on the two soaking storms earlier in May that hit the Denver Metro hard. Spotty showers (+a few storms) will be possible in the Boulder-Denver area Wednesday PM, the focus being the higher terrain #COWX

There's another NSF NCAR Explorer series lecture this week in Boulder. 🌎 fluxART: Experiencing Earth system science through art ⏰ Wednesday, May 27, 2026 @ 7:00-8:30 PM MDT (in person or online) ℹ️ Details and sign up here: www.eventsquid.com/event.cfm?ev... #COwx #Colorado #Boulder #NSF

We've got daily storm chances all week long with Colorado stuck in a stubborn blocking pattern, but SE-erly steering flow will be a problem for us on Tuesday ↖️🙀 This & more in our latest *Premium* morning discussion: bouldercast.com/bouldercast-... #COwx #Colorado #Denver #Boulder

This Week in Colorado Weather: Hit-and-Miss Storms All Week Long ⛈️ While no day looks like a washout, the pattern does get more interesting mid‑week as deeper moisture sneaks in and storm chances tick upward Latest forecast: bouldercast.com/this-week-in... #COwx #Boulder #Denver #Colorado #Rainy

The latest multi-model plume from Columbia University’s IRI shows growing agreement as we move beyond the spring predictability barrier, with most guidance clustering around a peak Niño‑3.4 anomaly of 1.8–2.2°C heading into late winter—similar in magnitude to the recent 2023–24 El Niño #COwx #ElNiño

Beautiful Saturday on the gravel. Starting to look a bit more green out here. Name that peak! #cowx #boulderwx

7th day in a row with measurable rain in Boulder #cowx

It's been a cool and gorgeous Friday so far, but don't totally write off the evening rain chance. Spotty showers, isolated storms will be around from 6 to 10PM #COWX

Boulder Just Matched Its Last 7 Months of Precipitation — In Two Weeks ❄️☔️🌊 Here's What It Means for the Ongoing Extreme Drought: bouldercast.com/colorado-dro... #COwx #Colorado #Boulder #Denver #drought #monsoon

It's really comforting to look at radar and actually see some activity day in and day out over Colorado. It was a rough six months there... #COWx

First jet-forced rain and snow band is popping up over Boulder now. Short range guidance has been insistent this puppy will sit directly over Boulder County for the next 10 hours making for a soggy Tuesday while much of Denver is dry. #cowx

💦 Boulder has received more rain (and melted snow equivalent) in the last two weeks than the entire four months prior. Over 3" of moisture so far in May has greatly reduced our 2026 YTD deficit, but there's still much more catch-up to do... #COWX #Boulderwx

This Week in Colorado Weather: A Rainy Week Ahead Before a Holiday Weekend Warm‑Up It sure has been cold and wet, but we're not done yet. Plus a look at how things are shaping up for Memorial Day Weekend (spoiler: not bad!): bouldercast.com/this-week-in... #COwx #Colorado #denver #BouldeR #Rain

Another beneficial dose of moisture dumped on Colorado during our recent storm! 💦 We may trounce this drought sooner rather than later after all if this keeps up, at least in the Front Range. Hooray! 🥳 #COwx #colorado #Drought #denver

Freeze Watch has been cancelled for Boulder/Denver where low clouds, shallow upslope, fog and mist will persist through much of the night ahead keeping us above freezing. Frost possible in outlying areas many miles away from the terrain where skies may clear. Yay plants! #COwx

Roads on some mountain passes becoming snow covered this morning (Berthoud Pass shown here) as colder air and heavier snow moves into Colorado's Front Range. Snow levels now down ~6800-7000 feet with accumulation occurring atop Flagstaff Mountain in western Boulder #COWx

Here's our updated most likely snowfall amounts for the Boulder-Denver area through Monday night. Wet snow for the higher terrain above 7,000 feet but generally just a few wet flakes mixing in with the cold rain across the lower elevations of the Denver area. #COwx #colorado #Denver

Strong Loveland K-9 unit police presence in snowy Rocky Mountain National Park this morning 🤔 #COwx

Glorious steady, chilly rain is falling over much of the Front Range this morning. Intensity and coverage will pick up as the next batch of energy moves in from western Colorado. Snow levels continue to slowly fall. Rates 1"/hr possible 10AM-4PM. Isolated thunder as well #COWX

RRFS forecast for additional rain and snow amounts through Monday night. Another inch or so of juice favored in and near the Boulder/Larimer County Foothills. Closer to ~0.5" in Denver. 2 to 10 inches of snow above 7500 feet, greatest above 9500 feet on the eastern slopes of the Divide. #COWX

💦 0.49" of rain officially in Boulder so far. Most locations around the Denver Metro have picked up 0.25 to 0.75", with locally over 1" in the Foothills of Boulder/Larimer Counties. Hoping to at least double these totals by the time precip ends Monday night. #COwx

Rain, wet high‑elevation snow, and even a few rumbles of thunder will unfold on Monday across the Front Range ☔❄️⚡ We also check in on the declining chance for freezing temperatures Monday night. This & more in today's *Premium* Storm Update: bouldercast.com/storm-update... #COwx #Colorado #Denver

It's going to be a soggy overnight for the Front Range, especially Boulder/Larimer Counties with snow levels dropping from 10,000 feet down towards 7,000 feet by sunrise. Chilly rain, mixed at times with wet flakes, will continue most of Monday in Boulder and Denver #COWX

Nice evening storm passing through. Pea sized hail in Longmont. 📸: Karin G

❄️ Spring snow will return to Colorado late Sunday though Monday, mainly in the higher terrain, where up to 16" may fall along the Continental Divide. A few wet snowflakes may mix in across Boulder & Denver Monday afternoon and evening with little to no accumulation. #COWX #colorado #denver

Nice steady rain. Yes please and thank you! 😊 #cowx

Colorado Forecast Update: Another soaking storm is headed for the Front Range. Fortunately it’ll be too warm for (much) lower elevation snow this time 🥳☔️ We break down the timing, the most likely precipitation/snowfall totals, & the post-storm freeze risk: bouldercast.com/colorado-for...

There is a Marginal Risk (Level 1 of 5) of severe weather in the Denver area on Sunday. A much better chance of large hail, damaging winds and a tornado exists in the I-70 & I-76 wedge zone well east of Denver where a few supercells will form during the afternoon/evening. #COWX

Good Saturday evening, everyone! Just a quick update on the inbound, moisture‑loaded storm poised to impact Boulder, Denver, and the broader Front Range from Sunday through Monday. Fortunately this one is coming in a tad warmer, but that doesn't mean no snow at all: bouldercast.com/saturday-eve...

Nice clustering of supercells in far eastern Colorado this evening. Mainly 1-1.5" hail and wind. Had a few showers earlier in Boulder, and may see a few more light ones through the evening but the (very slight) severe risk ship has sailed in the Denver area for today #cowx

👀 #COWx

It was a hot one out there today and unsurprisingly TWO new temperature records were set in Boulder: 🥵 TIED record high at 88° (joining 1996) ♨️ NEW record warmest minimum at 62° (previous 60° 1988) #COwx #Heatwave #Boulderwx #Boulder

Gorgeous black mammatus were present over Boulder, Niwot and Longmont Wednesday evening around 6PM, shown here just outside the view of our camera 😍 Anyone get a good picture of these puppies? #cowx #boulder

Last week's big sloppy snowstorm has brought slight drought improvement to northeast Colorado. A good start, but there's much more work to do through the summer if we want to claw out of the this statewide long-term drought. 🏜️ #COWX #Drought #colorado

Near-record heat rolls on for a couple more days but cooler weather is looming in the extended for the Front Range 🥵⛈️📉 This & more in our latest *Premium* weekend outlook: bouldercast.com/this-weekend... #COwx #colorado #denver #Boulder #Drought #Monsoon #ElNino

Thickening afternoon clouds could spoil Boulder’s bid for earliest 90° day on record, but we're still many days away from cooler weather 🥵 This & more in today's *Premium* forecast discussion: bouldercast.com/bouldercast-... #COwx #Boulder #Denver #colorado #Heatwave

🌡️ Boulder hit 88° on Monday, tying the May 11th record high for the city previously reached in 1961, 1962 & 1963. #COWx #Boulderwx

This Week in Colorado Weather: Summer in May 🥵📈🌄 A warm, summer-like pattern is about to take over the Front Range in the middle of May with our first 90° day up for grabs alongside little hope for any rain: bouldercast.com/this-week-in... #COwx #Colorado #Denver #Hot #Boulder

April 2026 Graphical Weather Review: A warm, bone-dry month that sure didn’t rescue Colorado’s snowpack 🌎🏜️🏔️♨️ April 2026 wrapped up as another water‑starved month along the Front Range, trading March’s record heat for storm systems that looked promising on paper but rarely delivered. #COwx #colorado

Few rain showers around tonight. Nothing major but don't be surprised to get a quick sprinkle or shower #cowx

Still an absolutely abysmal snow season, but about 20% less abysmal than it was before this week's sloppy snowstorm! 🤠#COWX #Denver #Boulder #Colorado

Just another Wednesday in Colorado! ❤️ #COwx #Colorado

Hard freeze warning busted in Boulder Wednesday night, and probably in your location, too!

💦 Well the storm totals are in...and they were BIG in Boulder! Not enough to solve our problems, but it's a step in the right direction. #COWX #Boulderwx #Drought #Colorado
