CHEYENNE, Wyo. — Southeast Wyoming is bracing for a mix of midweek weather, with showers moving east overnight into Wednesday. The National Weather Service in Cheyenne is forecasting snowfall west of the Laramie Range, transitioning to a mix along the Interstate 25 corridor and becoming more widespread across the High Plains by Wednesday afternoon.
Highlights:
- Mountain snowfall in south-central Wyoming will continue through Thursday, impacting areas along I-80 in Carbon County.
- Strong winds are anticipated over the weekend and early next week, followed by a temperature drop toward near-average levels.
Snow bands developing across southeast and south central Wyoming are lifting northeast, with snowfall intensifying through Wednesday. The forecast aligns with the increasing confidence in banded snowfall, especially in Carbon and Albany counties, extending into the High Plains. However, precipitation is expected to be all rain below 5500 feet as it reaches the Wyoming–Nebraska border.
Snowfall accumulations remain as previously forecast, with northern Laramie Valley and Upper North Platte River Valley, including Saratoga, added to the winter weather advisory. Snowfall totals could reach 6 to 8 inches in areas under heavy snowbands for extended periods.
The Sierra Madre Range has already seen significant snowfall, warranting a winter storm warning, while the Snowy Range continues under a winter weather advisory due to localized downslope effects.
Snowfall is expected to conclude before noon Thursday as a Pacific upper-level trough moves eastward into the Great Plains. Although temperatures will drop Wednesday night into Thursday, they will remain near or slightly above average for this time of year.
Looking ahead, a quieter weather pattern is forecast to end the workweek. However, Wyoming winds are set to return over the weekend into early next week, with potential high wind events anticipated. Despite model differences on the strength of the 700 millibar jet, a windy weekend is expected across southeast Wyoming, with temperatures remaining above average due to strong downsloping winds.
