Mostly sunny, dry, and cooler behind a weak cold frontal passage this morning. High near 90 degrees. Continue reading for today’s full forecast.
At 500 mb today, we have zonal flow across the state, somewhat strong at around 40 knots. With flow this strong (quite abnormal for summer), we can actually call this downslope flow.
GFS 500mb vorticity for this afternoon
As we mentioned yesterday, a very dry air mass has invaded the state. Combining this lack of moisture with a weak cold frontal passage this morning, we’ll be in store for comfortable conditions today across the region. The 800 mb temperature map below shows the north-northeasterly flow behind the front. The timestamp for the map is at noon, and the front has already pushed through Denver.

As such, we’ll be cooler today compared to yesterday (which by the way, hit 97 degrees at BoulderCAST and 95 at Boulder Airport). Expect plenty of sunshine with highs in the upper 80’s. Humidity will be very low and comfortable, likely dew points hovering in the 30’s and 40’s. Not a chance of rain either, even over the Mountains.
Enjoy it! This is the best summer has to offer in Colorado!
