Cache Valley climbed out of the freezer and into the refrigerator on Thursday as temperatures climbed 10 degrees. Thursday’s high was 22, which, with some sunshine, felt a bit better than the 12 degree high temperatures of Tuesday and Wednesday.
The National Weather Service Salt Lake office says looking ahead, this weekend we are expecting a flow pattern aloft that brings stronger southerly winds just above the surface, which typically helps erode cold pools of area that we experience locally. But, the valley might be one of several places for which that process is the slowest to take effect.
Right now, we expect some mixing and breaking out of the inversion by Sunday, but it could come earlier or later. As is the case with winter inversions, the air quality has been deteriorating. As of early Thursday evening, the PM 2.5 level in Cache County was in the ORANGE range, which prohibits solid fuel burning devices. Also, open burning is not allowed, including fire pits, fire rings, and campfires. And residents are encouraged to reduce vehicle use by consolidating trips.
