09/11/26 9am: Happy Friday! Nice to have some weather to talk about. A cold-front for early tomorrow am and then looking at a round of active weather especially for the Front Range (and parts of western CO), Mon afternoon through Wed (Tue is likely going to be rainy for Den/Bou).

Anyway, for today a few rain showers and weak thunderstorms over parts of western CO and the mountains, from 1pm-9pm, favoring the southwest part of the state this evening.

For Den/Bou and the front-range turning cloudy this afternoon with a few high-based storms 5pm-10pm, won't be much.

Then models show a cold-front moving down the front-range, across eastern CO tomorrow morning 12am-6am. It will be cooler for Den/Bou tomorrow with highs just near 80 in the afternoon (cloudy and cool in the am).

For tomorrow afternoon a chance for isolated to scattered thunderstorms for both the north-central mountains and front-range (Den/Bou) from 2pm-8pm, favoring areas east of the Cont. Divide (front-range mountains and foothills). Best chances for Den will be after 4pm Sat (won't be much).

Then back to fairly hot weather across the state on Sun....but a chance for storms mostly over western CO and the mountains (west of the Divide) from 3pm-9pm on Sun (mostly isolated activity).

Then the weather gets interesting from Mon-Wed. Models show a stronger cold-front moving down the front-range / eastern CO on Mon afternoon / evening, and some more consistent rain and thunderstorms may move in behind the front, mostly after 6pm Mon. This will combine with some deeper moisture and a few short-wave moving in from the west.

Heads up the Broncos game could be impacted, bring your rain gear...

But overall best chances for rain on the front-range (Den/Bou) will initially be from 11pm Mon through 11pm Tue, Tue looks to be the wettest day next week.

Looks like good rain chances and unsettled weather will continue into Wed, before drying out before Thu

Cooler for Den/Bou next Tue/Wed, maybe highs only in the 60s.

Also good rain and thunderstorm chances for parts of the mountains on Mon, Tue and Wed, favoring west / southwest CO: from the Elks to the San Juans, 1pm-9pm each day for some rain showers and thunderstorms.

For the north-central mountains also some decent rain / thunderstorm chances on Mon, Tue and maybe Wed, but not nearly as much coverage or total rain compared to west/southwest CO.

There could be some mountain snow above 12,500ft on Mon night, Tue nigh and maybe Wed night (09/14-09/16), favoring Elks to San Juans.

That is all for now, have a great weekend. Enjoy the fall colors in the mountains. I'm looking forward to more active weather next week. I'll be back in the mountains next week for fall colors as well.
