St. John Valley weather for March 4-10, 2020
Short-Term Outlook: Wednesday – Friday
Intensifying low pressure will track along the Downeast coast today. The track is further north than anticipated which is resulting in warmer conditions than earlier model runs suggested. Consequently, more liquid precipitation and less snow are now expected from this system. Presently, a couple of inches of snow are expected for northern Maine by 7 PM this evening and perhaps another inch overnight.
Winds will pick up as the storm intensifies with areas of blowing snow anticipated this afternoon into the overnight hours. High pressure over the Mid-Atlantic will build in Thursday and Thursday night. Cloudy increase Friday morning as a cold front associated with a clipper system moves through with a slight chance for some snow through the afternoon hours. Skies become partly cloudy Friday night as high pressure builds into the Valley.
Wednesday, March 4
Cloudy with a 100 percent chance for rain/snow this morning changing to all snow this afternoon and continuing into the evening. Some fog possible in the morning. Around 2-inches snow accumulation expected (around 0.25 inch liquid). High in the mid-30s with east winds 5 to 10 mph becoming west/northwest 10 to 15 mph with gusts 25 to 45 across the region. Areas of blowing snow expected.
Tonight, cloudy with a 70 percent chance for snow showers with a low in the lower 20s. Around 1 inch accumulation possible (< 0.10 inch liquid). West/northwest winds near 15 mph with gusts to around 25 mph.
