CASPER, Wyo. — Unseasonably warm weather will give way to unseasonably cold conditions by the Thanksgiving holiday in central Wyoming.

“We are monitoring a potentially impactful winter system coming this Thursday/Friday, which would bring much colder temperatures and potential for snow accumulations,” the NWS in Riverton said on social media early Monday.

According to the NWS in Riverton, Sunday night’s scattered rain and snow showers are expected to clear early Monday, leading to a high around 48 degrees. Tuesday and Wednesday are expected to be sunny and breezy, with high winds at times. A high of 48 degrees is expected on Tuesday, and a high of 55 degrees is likely on Wednesday.

The outlook changes by Thanksgiving day, as snow and cooler temperatures move into the Casper area. Thursday will see a high around 35 degrees, dipping to 19 degrees overnight. The NWS in Riverton expects Friday’s high to only reach 26 degrees, and overnight lows should dip into the single digits.
