CASPER, Wyo. — It’s spring in Wyoming. There’s snow in the forecast.

Casper saw some snow overnight, and there’s a 50% chance for more before noon. Despite mostly cloudy skies, the high will return to around 43 degrees and snow chances will taper off. It’ll be breezy today with a west-northwest wind of 14–22 mph with gusts reaching 33 mph, according to the National Weather Service in Riverton.

Tonight, the low will fall to around 28 degrees. Winds from the southwest at 11–16 mph will increase to 23–28 mph. Gusts overnight could reach 41 mph, according to the forecast.

Active weather is in store for western Wyoming on Saturday. A Winter Storm Watch will be in place for the Tetons and Yellowstone starting at 6 a.m. Saturday. Meanwhile, Casper will see strong winds as a result of the jet streak falling over central Wyoming. The forecast high is 50 degrees, but winds from the southwest will reach sustained speeds of 30–40 mph with gusts as high as 60 mph. That will continue into Saturday night as the low falls to around 38.

The expected winds have led to a High Wind Watch being issued for Natrona County on Saturday and Sunday.

A similar setup will be in place for Sunday as the high returns to 50. Winds from the west–southwest will blow at 26–33 mph with gusts reaching 50 mph.

Snow chances with the upcoming storm start Sunday night. A 20% chance will increase to 60% overnight as the low falls to around 30. Winds will die down from 20–30 mph from the west to 10–20 mph from the east.

There’s a 90% chance for moderate to heavy snow Monday and Tuesday, with snow chances falling to 40% Tuesday night and further Wednesday. Monday’s high is forecast at 38 degrees, with colder air settling in Tuesday for a high of 29.

“It is still too early for details for placement of the heaviest snow, but this storm has to be watched since it may have major impacts on transportation across much of the state. And this will be followed by another spell of very cold temperatures. It will not be as cold as other times this winter, but more record lows are likely for the middle of the week,” meteorologists wrote in the forecast discussion. “So, winter is still not going anywhere anytime soon.”
