The upper-level trough mentioned yesterday has shifted further east, but it will only offer a glancing blow to Colorado.

There is only limited organization, and the best lift for precipitation (associated with an upper-level jet streak) will remain to our south today.

The biggest influence for us will be a slight cool down compared to recent days. Shown below is the 800 mb temperature map for this afternoon. Notice the fringe of the trough’s cold air reaching into NE Colorado.

Highs will only climb to near 60. After morning sun, expect mid-level clouds to increase through the day, with widely isolated showers forming in the afternoon. We expect most of the action will remain south of Denver. Any rain that does fall across the Boulder area should be short-lived.

After today, we’ll see temperatures warm up into the 70’s and dry out until Sunday. Models continue to show a wet beginning to next week. We’ll continue to watch that closely for the threat of more substantial precipitation for the region.

Happy Wednesday!
