Weather: Messy start to the holiday weekend (12/21/2017)

Storm Summary for December 22 and 23 2017

Doesn’t it always seem to work out like this? You’ve got holiday travel plans and now you probably have weather worries. Friday and Saturday, things get pretty messy. It’ll start as widespread light snow Friday morning and continue much of the day. I don’t see many issues for the morning drive but the evening commute will get sloppy. Snow will gradually change to mix of snow, sleet, rain, and freezing rain Saturday morning. By the time we start to see a switch, expect a widespread 3-7″ on the ground. Isolated spots in central & southern Vermont & New Hampshire may close in on 8″ or more.  Everyone will see that mix of snow, sleet, freezing rain and rain continue during the day Saturday.

It’s looking more and more likely that cold air will get stuck in southern/eastern Vermont & especially central/southern New Hampshire. This opens the door for close to a quarter of an inch of ice to accumulate. That’s enough to make driving difficult and coat trees and lines with a light glaze. I don’t see big ice storm type impacts happening but it will get pretty icy. Saturday night and early Sunday, everything switches back to snow before ending. If you’re doing any traveling or are expecting friends/family to come in from out of town Friday & Saturday, there may be delays.

Sunday, we stay partly to mostly cloudy but much of the day will be quiet with highs around 30°.  Christmas is on Monday and we’re starting to get a better idea on our snow potential. The odds of seeing a blockbuster storm are going down but we should still have off and on snow around. Exact amounts are still hard to pinpoint but a few festive inches are certainly possible. A white Christmas is a lock for us. Tuesday through Thursday light snow showers linger and gradually end but the bigger weather story will be the cold. A big pool of arctic air will spill into the northeast. Highs Wednesday and Thursday will be lucky to hit 10° with lows around or below 0°.
