Snow Melt and Preservation...

The wet moisture laden snows may not all melt off by the end of next week but a warm up is expected between now and then. A Halloween cold front will bring enough colder air later this evening to fire some sprinkles first but then a glancing blow of relatively colder air to settle into place for Saturday. This will slow down the recent melt-off and preserve the snow as it will be some kind of chilly.

This next chilly air mass with the reinforcing shot of colder air on Saturday will eventually moderate over Sunday and Monday. An area of higher pressure will set the stage after the next shot of rain showers on Monday.

Tuesday Election day will begin a large reconfiguration on the jet stream which will have lasting effects the rest of the week. A large dip in the Jet stream out west will pump more ridging in the east, setting the stage for a southwesterly feed of milder air into the region and thus melting of snows on the slopes for much of next week.

As we get into next weekend around the 8th,9th and 10th, the polar vortex was forecast to weaken considerably and release VERY COLD AIR toward the middle latitudes. This should have ramifications with the jet stream pattern and migratory storms across northern New England in the favor of more snow, the big question at that point will be - does this colder air stay around, or does it progress again to another oscillation for warmer conditions?

I vote for the former!
