06/18/26 2pm: Ah, so much nicer out there today. Just finished eating lunch outside in Boulder where its only 77 right now (was 92 at this time yesterday). Quite a bit cooler along the front-range behind last night's cold-front (the second front).

Only 81 in Denver (at DIA), 78 in Ft. Collins, 77 in Boulder, 71 in Springs (was like 96 this time yesterday).

Still hot over western CO and the mountains. Its 76 in Silverthorne (almost the same temp as Boulder) and 93 in Grand Junction right now.

Also "severe clear" over the state right now with almost no clouds across much of the state.

As I mentioned this morning, better rain chances return for the eastern half of the state on Sat and Sun, but will still be limited / spotty.

First image is latest surface map. Second image is current visible satellite/surface overlay. Third image is temperature analysis from 12pm.

How is your Thu going weather-wise? Enjoying the cooler temps on the front-range?

06/18/26 8:45am: Morning, Its Thursday so lets check-in on the updated drought monitor for CO. Not much has changed since mid-May.

The big concern is that parts of the north-central mountains / northwest CO remain in D4 Exceptional Drought, this includes much of Grand, Summit, Eagle, Pitkin, Lake counties and parts of Routt and Garfield counties as well. Most of those area have had no meaningful rain/snow since early May (and some areas since April), so we really need some rain across western CO and the mountains but we will likely have to wait until the southwest monsoon kicks-in, hopefully sometime in July / August.

The front-range and parts of southern CO have had some improvement (but remain mostly unchanged since May). We have had more of a southern track / upslope flow recently which is not uncommon in May / June (where eastern CO is favored for heavier precip).

Maybe some relief coming by Sat/Sun but it could be mostly over eastern CO and the front-range again (models show most the activity east of the Cont. Divide).

I have also include % Normal Precipiation over the last 60 days and last 6-month, clearly we have been very dry here in CO! (aside from the one big storm in May).

What are your thoughts on the drought conditions? Especially in areas near Eagle county, where its been really dry?

06/17/26 8:45pm: Was a scorcher across Southeast CO today and the Western Slope. The little cool-front saved us a bit in Denver/Boulder and in areas further north. Was also hot in the mountains.

High temps of 100-108 across parts of the state today. It was also 80 in the mountains / Silverthorne.

First image shows high temperatures today across the state from the NWS obs / hazard viewer (some stations are not official).

Here are some notable high temps (some of these were record highs for the date):

Pueblo: 106
Rocky Ford: 104
Grand Junction: 100
Delta: 100
Canon City: 100
Trinidad: 100
Colorado Springs: 98
Montrose: 97
Durango: 96
Broomfield: 93
Denver (DIA): 91
Ft. Collins: 91
Meeker: 91
Boulder: 90
Alamosa: 90
Steamboat Springs: 89
Buena Vista: 88
Evergreen: 86
Aspen: 85
Sterling: 85
Silverthorne: 80
Leadville: 75
Berthoud Pass: 57

Not quite as hot tomorrow and Fri (upper 80s for Den/Bou, 60-80 in the mountains).

Then hotter again Sat (low 90s for Den/Bou) but with better afternoon thunderstorm chances in both mountains and front-range. Maybe some stronger storms on the eastern plains Sat afternoon.

First image shows high temps (max-T since midnight). Second image shows temp analysis from 7pm this evening. Third image is latest surface map showing current temps, dewpt, wind-speed.

06/17/26 1:20pm: Saved by the cold-front! Not as hot as expected for the northern front-range (Den/Bou) and northeast plains this afternoon behind and a mid-morning cold-front (that was supposed to come in this evening).

In fact at 8am Denver was at 86 degs, its 1:20pm and Denver is still at 86 degs. Parts of the northeast plains are in the low 80s right now and holding steady.

Compare that to areas south of the front, Pueblo is currently sitting at a scorching 100 degs.

In the mountains pretty hot and breezy: 74 currently in Silverthorne with some wind.

Parts of the Front Range mountains (IPW, RMNP, etc) have had wind-gusts of 50-70 mph today already.

06/17/26 9:15am: In other weather news (since the weather in CO is boring). A fairly significant severe weather outbreak is expected across parts of Upper Midwest today, with very strong storms, larger hails and a higher chance for strong (>EF2) long-track tornadoes.

The focus is right over central IL, generally south of Chicago in the 1pm-8pm timeframe. I'll be watching the radar later.

06/17/26 9:05am: Wow, already very warm out there! On my way into work this morning (from Westminster to Boulder) it was already 86 deg in Broomfield; pretty similar right now in Denver and Boulder (84-87 currently).

The wind is starting to pick up as well. Windy already over the Front Range mountains and foothills. As we have been talking about, its going to be a scorcher today with high fire danger across the state (no burning today).

Latest surface maps below showing current temps, dewpt, wind-speed, etc. The temp analysis (3rd image) is from 7am but you can already see the heat building.

06/16/26 9pm: It was a warm one today and will only be getting hotter tomorrow. Looks like tomorrow will likely be the hottest day of the of the summer season so far with high temps climbing into the mid to upper 90s for much of the front-range and near 105 for parts of southeast CO.

First already getting pretty hot out there. Here are a few notable high temps:

Pueblo: 101
La Junta: 95
Grand Junction: 94
Denver (DIA): 93
Boulder: 93
Colorado Springs: 89
Alamosa: 85
Silverthorne: 76
Berthoud Pass: 54

For tomorrow: hot and windy with high fire danger.

Much of CO, and all of western CO (including the north-central mountains) is under a Red Flag Warning tomorrow: 12pm-9pm, hot temps westerly wind-gusts of 30-60 mph, strongest over the Front Range mountains.

For Den/Bou and the front-range, high temps between 92-98, with some gusty winds of 20-40 mph in the afternoon.

Parts of southeast CO will be really hot with expected high temps of 100-105.

Actually parts of Colorado Springs to Pueblo area is under their first Heat Advisory of the season (high temps of 97-103)

Some relief on Thu behind a mild cold-front that will move down the front-range late Wed night into Thu morning (should drop high temps by 10-15 degs).

First image shows expected high temps tomorrow from NWS Blend of Models, I circled the hot area. Second image shows forecast wind-gusts at 2pm tomorrow from latest HRRR. Third image shows all the current Red Flag Warnings (red) and Heat Advisories (orange).

06/15/26 8:45pm: Hi, I hope you are having a good Monday, was pretty nice out there weather-wise today with comfortable temps. Anyway, lets take a look at what we can expect coming up this week and beyond.

Initially, I'm seeing a bit of blowtorch pattern for Tue and especially Wed with strong wind and hot conditions. It looks dry across the state through Thu.

In general I see an overall dry pattern for the next 2 weeks, not uncommon for mid-June in CO before the monsoon develops later in July / Aug.

Just some wind for now. Much of western CO is under a Red Flag Warning for Tue and Wed.

For both the mountains and front-range, on/off strong wind from 12pm Tue through 12am Thu, strongest Wed afternoon with westerly wind-gusts of 30-60 mph (strongest over the Front Range mountains and foothills along/east of the Cont. Divide).

And temps will be in the low to mid 90s for Den/Bou and lower elevations on Tue and Wed (hottest Wed), so combined with the wind, high fire danger.

Then models show a weak cold-front moving down the front-range Wed night into Thu am and this will bring in some more clouds, a bit more moisture and cool things down for Thu (highs back in the 80s for Den/Bou), could be cloudy Thu am.

In terms of precip: basically none through Thu night.

Then moisture does start to increase some across the state from the south / southwest Fri into Sat. So a better chance for afternoon storms on Fri, favoring the mountains (may not be much for Den/Bou and front-range).

Then back to seasonally hot with limited storm chances for the weekend (but some moisture, likely afternoon storms in the mountains on Sat and Sun, but nothing huge).

Looking a ways out, maybe a bit cooler again with some upslope on the front-range next Mon/Tue (06/22-06/23) but that is a was out so who knows.

Then possible more active around June 28th-30th, but that is uncertain as well.

This is the time of year where we really start looking for signs of the monsoon developing....I'm not really seeing that yet in terms of a consistent, high pressure circulation to our south (that would push moisture into the state from both the Gulf or Pacific). Keeping my eyes peeled for that.

First image loop shows forecast PWAT over the next 7 days, we look for the deeper greens to blues for good moisture (for rainfall). Second image shows forecast max wind-gusts between 12pm-6pm Wed from ECMWF. Third image is forecast slide for Wed from Den/Bou NWS office. Fourth image shows the big ridge of high-pressure via 700mb temps over the state on Wed afternoon (will be hot).

06/14/26 10:40am: Its the tale of the two halves of the states this morning: socked in with low clouds on the front-range (with a wicked inversion over the Front Range mountains) and sunny and warmer with a few rain showers developing over parts of the south-central mountains. Its sunny and mild in Silverthorne with temps in the low 60s.

Only in the 50s in Den/Bou right now, socked in with clouds.

Check out the very cool inversion up by Rocky Mountain Nat. Park this morning (h/t Den/Bou NWS office, from 8am this morning).

For the rest of today some rains showers / weak thunderstorms in the mountains mostly from Summit Co south (well south of I-70).

And on the front-range, most of the activity from Castle Rock south (towards Springs to Pueblo): 1pm-9pm today.

How are conditions in your neck of the woods this morning?

06/13/26 7:45pm: Hi, I hope you are having a good Sat. Nice to see at least some rain showers in spots this evening and that cooler air feels oh so good. Here in Silverthorne, looking out at cloud skies, with low clouds and some rain showers moving through at times, and its getting a little chilly (around 60 degs up here now in Wilderness), not much rain but some.

A few showers over the front-range as well now (near Den/Bou and in the foothills), with the heavy stuff over southern / southeast CO as expected. Not that much rain making it to the ground but good to see temps in the 60s even at lower elevations.

Could be worse (or better depending on how you look at it). Its currently only 37 degs at the top of Berthoud Pass! Nice for mid-June :)

First photo is latest composite radar over the state. Second image is latest surface map showing current temps, dewpt, wind-speed and precip. Lastly, It was beautiful in Summit Co earlier today, a few pics from our bike ride from Dillon to Frisco along the Lake path today. We saw a nice group of deer near the river path initially.

How are conditions in your neck of the woods this evening?
