Weekend: some showers/thundershowers, long dry periods

Friday, August 1, NOON


Warm weather (not hot) is in store for the next three days, with only small chances for afternoon showers/thunderstorms in the Denver-Boulder-Fort Collins-Cheyenne area. I wouldn’t be surprised if there is no afternoon shower activity on Saturday. The chance for afternoon thunderstorms is a little greater for the mountains south of I-70 and for the Front Range from Colorado Springs and south, especially today.


The fetch of tropical Pacific moisture (the monsoon) that affected us this week is being pushed a bit to the south and west of the Front Range region, but not very far. It appears that a significant pulse of moisture may move northward into western Colorado early next week, and possibly over the Front Range, enhancing the chances for rain. An update will be issued Sunday or Monday if needed.  For those who don’t know, mid July through mid August is the climatological peak for rainfall associated with the North American monsoon in Colorado. Last September’s remarkable surge of tropical moisture was after the typical peak in the monsoon season.
