4- to 7-Day Outlook: Saturday, March 15 – Tuesday, March 18
High pressure drifts east Saturday while a low pressure system tracks towards the Great Lakes fro the northern Plains region. The low lifts a warm front towards the Valley Saturday into Sunday with a cold front crossing the region Monday. Clouds increase with rain likely by Sunday afternoon continuing through Sunday night then tapering to rain showers Monday that change to snow showers Monday night into Tuesday morning. Precipitation tapers off by Tuesday afternoon as high pressure spreads over the East Coast. NWS Caribou notes that “snowmelt and weakened river ice due to thermal rot, will cause river rises sufficient to break-up and move river ice in many locations, leading to an elevated risk for ice jam flooding by Monday.”
