Short-Term Outlook
A weak area of low pressure and trailing cold front will move through northern Maine today producing 1 inch or less of snowfall and less than 1/10 inch liquid precipitation across the region.

Low pressure will move along eastern Nova Scotia tonight as it tracks away from the Valley. High pressure will gradually build into the area Friday with lingering snow showers diminishing over the course of the day. Partly cloudy skies are expected across the SJV Friday night and Saturday as high pressure in the southeastern US builds across the region.

Today & Tonight
Cloudy with a 50% chance for snow mixing with rain in the afternoon. Liquid precipitation amounts in the 1/100 to 1/10 inch range. High in the middle 30s with southwest winds 0 to 5 mph shifting to the north later in the afternoon in the 5 to 10 mph range. Wind chill values ranging from the lower-to-middle 20s. Tonight, cloudy with a 40% chance for snow tapering to snow showers after midnight with little additional accumulation expected. Low in the lower 20s with north winds 5 to 10 mph.

Friday, November 8
Cloudy with an 20% chance for snow showers tapering off in the afternoon. Precipitation totals less than 1/10 inch expected. High in the low 30s with northwest winds 10 to 15 mph gusting to 25 mph, especially over higher terrain. Wind chill values in the lower-to-middle 10s.

Further Ahead
Clouds increase Sunday as a warm front lifts across the SJV followed by a cold front Sunday night producing snow showers over the course of the day and a rain/snow mix overnight with snow showers lingering across the region Monday. Current forecast model runs are suggesting a coastal low will track across the Gulf of Maine Tuesday which could bring the first significant snowfall to the region with snow showers lingering into the midweek period.
