CHEYENNE, Wyo. — The National Weather Service in Cheyenne has issued a high wind warning for parts of southeast Wyoming, including Cheyenne, effective from 11 a.m. today to 5 a.m. Wednesday. Residents are advised to brace for west winds at 35–45 mph and gusts of up to 70 mph. These conditions are likely to affect travel, particularly for lightweight or high-profile vehicles.
Today, Cheyenne will experience strong winds, with dangerous windchills expected to persist tonight. The NWS in Cheyenne warns that these conditions will spread into the Nebraska Panhandle. People are advised to wear layers if spending extended periods outdoors.
For the rest of the week, the outlook remains active with daily chances for snowfall and windy conditions, potentially leading to continuous blowing snow. Extremely cold windchill temperatures are expected, especially during the overnight and early morning hours.
NWS Meteorologist Brandon Wills explains that light snow showers have begun in the mountains, with cold temperatures and gusty winds causing negative windchills. The expected strong wind gusts of 60+ mph will create blustery conditions, particularly in the Snowy and Sierra Madre Range mountains, where significant snow accumulation is anticipated by Thursday morning.
NWS Lead Forecaster Aaron Woodward anticipates active winter weather to continue into the weekend, with concerns over extremely cold windchill temperatures. While Thursday may see a decrease in wind, cold and moist upslope flow will continue to impact the mountains. The weekend is expected to bring windy conditions, with snow chances across the region, although significant accumulation is not anticipated.
