St. John Valley weather for March 27-April 2, 2019
High pressure will crest over the region today and move east tonight. Mostly clear to partly cloudy skies and southwest flow will allow temperatures to moderate today and tomorrow. A warm front to the north will graze the Valley bringing increased clouds this afternoon. A cold front and embedded low pressure area will approach Thursday with increasing clouds and rain showers by the afternoon. Cooler temperatures overnight will allow precipitation to change to snow showers before tapering off Friday morning; little to no accumulation expected with any snow.
Clouds will increase early Saturday as another low pressure system and cold front approaches from the west while the previous cold front stalls out along the Downeast coast. Snow in the morning and early afternoon will change to all rain later with rain continuing through Sunday night as the cold front slowly moves through. Rain will taper to snow showers Monday before tapering off. High pressure will build in later Monday through Tuesday.
