The first week of November is in the books, and so far no signs of Winter. Temperatures have averaged out right where they should and the only frozen precip we've seen was from convective showers that dropped some graupel in a few towns Sunday afternoon. I shot some video of the graupel hitting my driveway.
Graupel is a soft ice pellet, kind of like a small hail stone.
November can be a snowy month in Maine. Portland averages about 2" of snow every November and Bangor a little more than that. However, there simply won't be enough cold for snow until the weekend. Late this week, a powerful cold front will blast through with a big temp drop. Saturday will be the coldest of the season with highs in the lower 40s and wind chills in the 20s and 30s. With strong northwest winds, the mountains will pick up a few inches of upslope snow. But as those winds glide down the mountains, the air will dry out, flurries will be possible but that's about it.
The weekend cold outbreak will be short-lived as temps moderate again ahead of a developing Eastern US trough. There are signs that trough will be in a more favorable position for the second half of the month leading to a more active storm track and possibly some snow chances too.
