CHEYENNE, Wyo. — Residents can expect a warmer start to the week, though unsettled conditions with daily chances for showers and thunderstorms will persist, according to the National Weather Service in Cheyenne. By midweek, a significant cooldown will occur, bringing below-normal temperatures and possible high-elevation snow.
Early Monday, Cheyenne experienced slightly warmer temperatures, creating a bit more instability in the atmosphere. Despite this, the area remains mostly dry and breezy, caught between departing low pressure in the southern plains and another system moving in from the Pacific Northwest.
For Tuesday, the forecast anticipates a stronger influence from an approaching shortwave, which could lead to cooler temperatures and increased chances of precipitation. The forecast models are divided on the extent of the cooling and wetting, with some keeping the area drier until Tuesday night.
A significant change is forecast for Wednesday as a cold front moves through. Expect much cooler temperatures as well, measuring at 5–8 degrees below average. This cooler air, along with daytime heating, may generate scattered showers and even snow accumulations in the mountain areas. The Snowy and Sierra Madre ranges might see light snowfall, while the northern Laramie Range could receive several inches if current trends hold.
Looking toward the weekend, the weather is expected to dry out and warm up again, with temperatures potentially nearing 80 degrees in the northeast panhandle by Saturday. However, forecast models suggest varying conditions by Sunday, making the exact weekend weather less certain.
As the week progresses, residents should prepare for rapid shifts in weather, from mild and moist conditions early in the week to a cold, potentially snowy midweek, followed by a warming trend heading into the weekend.
