St. John Valley Weather for March 6-12, 2019

Mostly cloudy skies are expected today as the upper-trough moves through with a few scattered snow showers possible across the region. High pressure building east from the nation’s midsection will bring colder temperatures to the Valley through Friday. High pressure will move into the Atlantic over the weekend allowing temperatures to moderate on return flow around the high. Low pressure will track from the Great Lakes into Canada Sunday into Monday with snow across the region Sunday night into Monday morning. As temperatures warm Monday evening, snow will change to rain showers before tapering to snow showers as another ridge of high pressure builds in from the Midwest Tuesday.
