The breeze returns for Saturday
High pressure works into the region for a brief visit, and a brisk northwesterly wind will help usher it in. Early morning clouds clear out along the coastal plain, which will bring a mainly sunny sky by around midday and hang on through the rest of Saturday. The cold air kicks up a bit of moisture over the mountains and north, which will bring a mix of sun & clouds. There is a chance for a flurry or snow shower over northern areas, along with the higher terrain in the west.
With the northwest breeze, cooler temperatures are expected away from the coast. Wind chill indices in the 20s and 30s are expected for all but southern areas.
Any clouds around clear out Saturday night, and the wind calms, and the cold settles into Sunday morning.
Mixed bag for the mountains & north on the way
A Colorado Low forms over the eastern range, picks up moisture from the south, merges with the polar jet from the north and moves eastward Saturday into Sunday. Maine stays dry during daylight hours on Sunday. Precipitation breaks out Sunday night. The mountains start off as snow, may see a bit of a mix of sleet and/or freezing rain into Monday morning, before flipping to all rain by around midday Monday. Northern areas stay mainly snow to start off before changing to rain early Monday afternoon. Southern and eastern areas stay wet from Sunday night through early Tuesday morning.
The higher elevations of the western mountains have the higher snow totals, with the valleys receiving lesser amounts. It will turn into a sloppy mess as the warm moist air works in. All in all, about ½-1" of liquid equivalent is expected, with higher amounts possible. While Monday will be wet and raw, this will help with the ongoing drought.
Coastal areas can expect gusty southeasterly winds in the 20-30 mph range, along with the higher elevations. As the low tracks into the Gulf of St. Lawrence, the wind shifts to the northwest bringing the cold air back in Monday night. Backside snow showers are possible for the mountains and north into Tuesday.
Temperatures & outlook through Friday
Average high / low for the north is 36° / 23°, for the south 46° / 30°. It appears we'll be running below normal north and a few degrees below and above in the south through the next week.
There is potential for some sort of precipitation Wednesday into Thanksgiving, but ideas are very scattered beyond Tuesday at this point. Stay tuned for updates on that.
Help fill the gaps!
For folks in western, eastern, and northern areas, the Community Collaborative Rain, Hail and Snow Network could use your support! Verification of precipitation is very important to improve forecasts. All ages can participate. Reporting is easy, and it takes very little time to do.
