09/20/26 10am: Good morning from Silverthorne (heading back to the front-range shortly). Anyway, cool and crisp up here this morning. Also cool and mostly sunny on the front-range (with some clouds in the foothills).

Below is a quick look ahead at the weather coming up over the next 1-2 weeks from a high-level perspective.

First models show a mostly dry cold-front pushing down the front-range and across eastern CO tonight into tomorrow (after 6pm this evening)...this may fire up a few scattered thunderstorms mostly east of Denver, over the eastern plains and Palmer Divide: 7pm-11pm. I don't think there will be much for Den/Bou.

Limited impact in the mountains as well (except for some more cloud-cover this afternoon / evening). But it will be getting cold tonight into tomorrow...models show low temps in the 20s / low 30s across much of the mountain areas tomorrow morning (even some teens in the coldest mountains valleys, Mon am).

Anyway, using the latest ECMWF forecast for Berthoud Pass, it shows a break in this rainier pattern today and tomorrow. Then a return to better rain chances / afternoon thunderstorms for the mountains Tue-Thu this week (09/22-09/24). Better chances for the front-range as well.

Looking a ways out, the next best chance for a more significant snowfall for the mountains (above 9500ft) would be towards the end of the month: 09/28-09/30 the ensemble models are showing a much better chance for some snow for Berthoud Pass (Eisenhower Tunnels, higher terrain of the north-central mountains, etc).

It could also be turning cooler and more rainy for the front-range as well 09/28-09/30. But its a ways out, so high uncertainty in the details.

Thats all for now. I'll be back in Westminster this afternoon. I'm glad I'm coming back to some cooler air.

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

Oh yeah, Go Broncos! We need a big turn around!

First two images show forecast chicklet charts from ECMWF Ensemble members for Berthoud Pass, first one is 24hr liquid precip / rain, second one for snow and you can see the periods of more active weather I indicated. Image 3 shows the potential trough around Sep 27th/28th. Image 4 shows tonight's cold-front via forecast temps from latest NAM model.
