F​riday

S​now is expected from the Wasatch into the central Rockies and the adjacent High Plains as the work week comes to a close. That means the Interstate 25 corridor, including the Denver metro area, could see travel impacted by at least light snowfall.

S​aturday

T​he system will tap into Gulf of Mexico moisture as the weekend begins.

Rain and thunderstorms are likely across the South and Ohio Valley. Severe thunderstorms could be a threat from eastern Texas into the lower Mississippi Valley, but the severity of the storms will depend on how unstable the atmosphere becomes.

T​he wintry side of this storm will be limited to light snow or a mix of rain and snow in the upper Midwest and northern Great Lakes.

S​unday

T​he cold front accompanying this system will race toward the East Coast to end the weekend.

R​ain in the Northeast could be accompanied by strong winds through the overnight hours. The Southeast will see rain, gusty winds and thunderstorms, some of which could be strong.

Another uncertainty in the forecast is how much snow there might be on the backside. Areas from the Great Lakes to the interior Northeast might see snow or rain changing to snow for a time through Sunday night before precipitation comes to an end.

E​arly indications are that any significant accumulations of snow will be confined to areas from northern New England southward into upstate New York and the central Appalachians.

A​nother likely impact from this storm will be strong winds. Winds will accelerate out of the south in advance of this system and they could be strong enough to cause at least modest impacts (power outages, coastal flooding, etc.) These winds will be strongest from late Sunday through early Monday, particularly at the coast or in elevated locations.
