There will be a pattern shift resulting in temperatures we’d typically see during the fall/late September.
Thursday’s highs across Montana will only get into the 50s and 60s, with even parts of northwestern Wyoming dipping into the mid to low 60s.
By Friday, the chill will make its way into most of Wyoming and the Dakotas, while Nebraska continues to see summer-like weather.
By the beginning of the weekend, temperatures will change drastically across most of Nebraska and we will even see only 40s for daytime highs in plarts of Montana and Wyoming.
Freeze Watches are already in place across parts of Oregon, with more freeze and frost concerns in the coming days.
