This post is being done a little earlier than normal because your blog writer is taking a short break between outside errands and decorating and a marathon indoor decorating spree that should have me all ready for my annual 6 week long Christmas display beginning on Monday December 1, which is tomorrow!
Now that we got that straight, let’s move onto today, the final day of the Thanksgiving Weekend. Warm air is moving in, but an inversion at low levels has caused a variable blanket of cloudiness, which has thinning and retreated at times to allow more sun, especially in southern and eastern MA and RI. We’ll be in and out of clouds and sun across southeastern New England this afternoon though sun should end up dominant as the inversion is finally erased by advancing mild air. Though a little sloppy underfoot where snow/ice are still on the ground and melting, not a bad day to be outside for any of the various reasons people may have to be out there today.
Now to the coming week. Yes the milder pattern we have been speaking of for the first third of December is getting underway, but this does not mean every day will be mild. It’s an overall milder pattern, relative to normal, than the one we saw for the majority of November. A Pacific jet stream will be dominant, but with plenty of cold air sitting across Canada, disturbances moving along the jet stream, while passing mostly north of southeastern New England, will be able to grab pieces of the cold air and toss it southward as they depart. This will result in quick cold shots behind these systems (Tuesday and Thursday of this coming week will feature those cold shots). Preceding the Tuesday cold shot will be a cold front passing by Monday pushing into mild air, bringing some cloudiness and a rain shower threat. A warm front will approach Tuesday night and may bring some light icy precipitation, but mild air will be quick on its heels for Wednesday, which will feature a chance of rain showers. By later Friday, another warm front will approach after the second cold shot, and there is some uncertainty as to how this sets up as we head into next weekend. We may be dealing with some unsettled weather which may include a variety of precipitation by next weekend as there will be a tendency for low pressure trying to form to the south while a cold high pressure area retreats a little bit to the north of the region. This part of the forecast is low confidence, and subject to much revision, so don’t give it much weight at this time.
