CASPER, Wyo. — Snow is in Casper’s forecast. Although that kicks off with a slight chance tonight through Monday morning, a more impactful system is expected on Thanksgiving.
The National Weather Service in Riverton has forecast today’s high near 51 under mostly sunny skies. As a low-pressure system and cold front that’s brought rain and snow showers to western Wyoming moves east, Casper will see a 20% chance for isolated showers later this afternoon.
That will transition into a 40% chance for rain, and then by 3 a.m. a 40% chance for rain and snow. This is the system that’s been capable of producing up to 6 inches of snow in the highest elevations of the state, meteorologists wrote in the forecast discussion. No snow accumulation is expected in Casper.
The low tonight will be near 33. Winds from the northwest will pick up from 5–10 mph to 11–16 mph after midnight. Gusts of up to 24 mph are expected.
Monday morning will see a 20% chance of isolated snow showers before 11 a.m. Skies will remain mostly cloudy as the high reaches 42. Breezy conditions are expected to continue with a north wind of 10–15 mph and gusts of up to 23 mph. Overnight, the low will fall to around 22 degrees under mostly clear skies.
“Tranquil weather then moves in for Tuesday and Wednesday with ridging over the area,” meteorologists wrote in the forecast discussion. “The next weather system, likely more impactful, will arrive just in time for Turkey Day. Reasoning here looks similar to yesterday. Confidence is over 50 percent for some snow across much of the area on Thursday and possibly into Friday as well. However, details remain highly uncertain.”
For now, the forecast calls for a high of 49 on a sunny and breezy Tuesday. Tuesday night will see partly cloudy skies and a low near 32. Winds will pick up from 8–15 mph to 15–20 mph.
Wednesday will be mostly sunny as the high reaches 54 degrees. The temperature on Wednesday will drop to a low of 27 overnight.
On Thanksgiving Day, there’s a chance of snow showers mainly after 11 a.m. Skies will be cloudy, and the high will top out around 36. Overnight, snow showers remain likely. The low will be near 17. Blustery conditions are expected.
Temperatures will be starkly cooler on Friday and Saturday as the mercury will struggle to get above 27 degrees.
