Novmber's Climate Report for Cheyenne & Casper

Cheyenne, Wyo. -

While the last few days of November were cold, Wyoming has largely experienced mild weather conditions so far this fall. Now, as we turn the page to December, a cooler outlook is expected.

Wyoming as a whole saw one of its warmest Novembers on record. For example, Cheyenne tied its 5th warmest November on record, and Casper experienced its 8th warmest November.

Snow was also minimal during November, with the only meaningful snowfall for most locations coming the weekend after Thanksgiving. Cheyenne picked up 2.3 Inches of snow in November, and Casper only picked up 3 inches of snow. Both of these numbers are over 5 inches below average for the month.

While this fall has been mild so far, things are expected to turn colder. Right now, there is an active La Niña weather pattern, which creates a more active jet stream over Wyoming. National Weather Service meteorologist Joshua Rowe says this will likely lead to cooler and wetter conditions this winter season.

“The general temperature and precipitation outlook for La Niña is more precipitation and colder temperatures. That is kind of the general outlook for that, but it can vary year by year.”

Looking at the winter outlook issued by the Climate Prediction Center, temperatures are leaning slightly below average for the northeastern half of the state, and near normal temperatures are expected for southwestern Wyoming. The precipitation outlook shows above average precipitation across the state, which means snow will start to become more of a regular occurrence.
