As temperatures are expected to soar here in the Upper Midwest this weekend, let’s venture to the Rockies and take a peek at how things will pan out in Central Wyoming!

At 1120pm MDT, the temperature at Casper, WY was 61 degrees under fair skies. Low pressure found over the Northern High Plains will shift its way into Central Canada throughout the day Saturday, trailing a boundary back into the Great Basin. Luckily for Casper, the main focus of any precip will be over the Dakotas as hot, humid air streams northward into the Northern Plains/Upper Midwest, kicking up storms off to the east. Low pressure that develops over the Great Basin Saturday shifts into the Central Rockies on Sunday. This increased cloud clover will bring much lower temps during the day, and as the overall boundary sags a bit southward, chances for showers and isolated thunderstorms Sunday evening increases.

Saturday: Mostly sunny. High 92, Low 57.
