Forecast for the weekend: decent storm chances Fri, drier Sat

05/30/25 8:45am: Happy Friday! Looks like we will have another decent chance for some afternoon storms along the front-range (including Den/Bou) this afternoon as models show a litle short-wave moving through on northwest flow. Also a good chance for storms across parts of the north-central mountains and front-range mountains (especially from Summit east).

For Den/Bou and the front-range today: scattered thunderstorms from 2pm-8pm. Best coverage west of I-25 and in/near the foothills especially in the 4pm-7pm timeframe.

For the north-central mountains: isolated to scattered storms from 1pm-7pm. Best coverage from Summit co. east and especially along/east of the Cont. Divide: Front Range mountain will be favored for stroms today.

Looking ahead drier and warmer on Saturday. Much of north-central CO and the front-range will remain dry on Sat.

Some storms over southern / southeast CO on Sat, mostly southwest of line from Leadville to Pueblo tomorrow (including SLV): 2pm-8pm Sat.

The wind will remain light on Sat into Sun.

Sunday will start out nice, then a better chance for afternoon storms return again, especially for the mountains after 1pm Sun (scattered storms for north-central and south-central mountains). Maybe a few for Den/Bou as well later Sun.

Then as I mentioned last night much heavier rounds of rain coming from Mon afternoon through Wed afternoon (mostly in the afternoons) as tropical storm Alvin combines with some short-waves in the jet-stream: heavy rain in spots each afternoon (Mon-Wed), more on that later.
