CHEYENNE, Wyo. — Cheyenne could see up to 8 inches of snow in a coming winter storm this weekend, National Weather Service meteorologists are warning.
The possible storm has prompted the NWS in Cheyenne to issue a Winter Storm Watch and a Hard Freeze Watch as temperatures are expected to plummet amid gusty winds and heavy snow.
Meanwhile, Casper is expected to see some snowfall and overnight lows below freezing on Friday and Saturday, according to the NWS in Riverton. Rain chances today and this evening will turn into a 40% chance for snow Friday despite a high forecast at 46 degrees. Snow showers are expected mainly before 1 p.m., the forecast states. New snow accumulation of less than a half-inch is possible.
Snowfall may end overnight Friday, but blustery north winds of 15–20 mph will bring the chill and drop temperatures overnight to about 30 degrees. Saturday is expected to warm to 50 degrees by the afternoon after a slight chance for snow between 7 a.m. and 2 p.m., according to the forecast. A 30% chance of snow is forecast before 7 p.m. Saturday, before temperatures fall to about 28 degrees.
In and around Cheyenne, however, an increasing chance for rain showers this evening will continue into Friday morning and become a 70% chance for snow mainly after noon, according to the NWS forecast. New snow accumulations of 1–3 inches are possible as Friday’s high of 40 degrees falls to an overnight low of 24. Overnight snow accumulations of 3–5 inches are possible, meteorologists warn. The Hard Freeze Watch goes into effect at 9 p.m. Friday and will last until 9 a.m. Saturday.
Snow showers are expected to continue into Saturday as the high reaches about 39 degrees. The Winter Storm Watch, which goes into effect Friday at 6 a.m., is expected to end at noon Saturday.
