Unseasonably cool weather warms into the weekend

Posted at 6:20 AM, Sep 21, 2023

Temperatures are running around 15 degrees below normal as a large, chilly storm system from Canada lingers over the region into Friday morning before exiting into Wyoming by Friday night. The Treasure Valley is experiencing dry, cool, and relatively pleasant weather.

High Temperatures Thursday

The low-pressure system responsible for the cool temperatures pulls away on Friday. If Boise is going to get any showers from this storm it would be late Thursday night through midday Friday. Temperatures will warm around 5° reaching the mid to upper 60s in lower elevations and mid to upper 50s in higher elevations Friday afternoon.

Boise 7-day

High pressure builds in for the weekend with temperatures warming into the 70s for the valleys and 60s for higher elevations. I expect some high clouds especially in the central mountains on Saturday otherwise hazy sunshine should make for a comfortable day. Clouds will likely be on the increase on Sunday. It does appear there will be a return to unsettled, cool weather next week as another Pacific trough moves into the Pacific northwest.
