CHEYENNE, Wyo. — Blustery northwest winds and snow showers will persist across southeast Wyoming today, creating hazardous travel conditions in some areas. Winds in wind-prone regions could gust at up to 50 mph this morning, diminishing slightly by late afternoon.
Snowfall accumulations are expected to be light, generally reaching less than half an inch for most locations, according to the National Weather Service in Cheyenne. The weather pattern remains influenced by a ridge off the West Coast and a low-pressure system near the Great Lakes, bringing repeated waves of cold, unsettled weather.
The NWS in Cheyenne reports that a series of vorticity maximums streaming out of the north will contribute to occasional snow showers and breezy conditions through the day. Vorticity maximums are areas in the atmosphere where there is a localized region of higher vorticity, or spin. Conditions should begin to improve this afternoon as drier air moves into the region.
Temperatures will remain chilly, with highs near freezing across much of the area. Another round of strong winds is possible tonight into Wednesday morning, particularly in areas like Arlington and Bordeaux. Elevated winds are expected in the gap areas, though widespread impacts beyond blowing snow and reduced visibility are not likely.
Looking ahead, southeast Wyoming will see a brief warmup midweek before a strong cold front arrives Friday. The NWS in Cheyenne warns that frigid arctic air will settle in, with high temperatures over the weekend expected to remain in the single digits to teens. Snow chances will increase, particularly Friday evening through Sunday, as the region braces for the coldest weather of the season so far.
