Weather Alert Day for eastern CO (for this Thu), a look at the weekend

04/24/25 8:45am: Morning, we will have some better thunderstorm chances along the front-range today as a cold-front moves in this afternoon / evening. Its a weather alert type of day for the eastern plains and front-range for some strong storms in spots. Not much action expected in the mountains west of the Cont. Divide

• For Den/Bou and the front-range a chance for scattered thunderstorms between 3pm-8pm, then a chance for rain showers from 8pm this evening through 4am Fri.

• Best chances for stronger storm locally will be from Boulder north to Ft. Collins / Greeley areas and along/east of I-25 and then further east onto the plains. West of I-25 it will be more isolated and hit or miss

• After 4pm, best chances for stronger storms will be east of a line from Greeley to Limon as indicated by the third image below. Some severe storms in spots with larger hail, wind and brief heavy rain

• For the north-central mountains some isolated weak storms from 1pm-6pm. Then tonight a few rain/snow shower mostly east of the Cont. Divide: Front Range mountains from 9pm tonight to 9am tomorrow: Trace-2" of snow in a few spots

• It will be much cooler over the front-range (Den/Bou) tomorrow (Fri) with high temps only in the 40s through noon (low 50s in the afternoon).

• Only 30s/40s for the Front Range mountains east of the Divide above 8kf t, so not much warm up or thaw out (maybe hard to find corn skiing tomorrow), a bit warmer further west (west of Summit Co) but still 40s for mountains

• It will be turning windy across the mountains from 2pm Fri through 4am Sat with westerly wind-gusts of 30-50mph. Less wind after 5am Sat and the wind looks light to moderate over most of the mountains on Sat.

• On Friday another chance for scattered storms for the front-range (Den/Bou) from 2pm-9pm, best chances in/near the foothills.

• Stronger storms expected over eastern / southeastern CO on Fri afternoon

• Overall looks dry across much of the state for Sat and Sun (should be great to be outside)
