Weekly Outlook: January 2-8, 2023

This week will start and end with quiet weather, but in between will be interesting.

High pressure provides the region with dry and mild weather today, though not as mild as the past few days. Clouds will start to move in tonight ahead of a low pressure system moving into the nation’s midsection. A warm front will approach on Tuesday, with some light rain and showers likely ahead of it during the afternoon and evening. Much warmer air will move in behind the front for Tuesday night and Wednesday, but the question becomes – how far north does the front get before stalling out. South of the front, temperatures will get well into the 50s or even 60s on Wednesday, but to the north, it will stay in the 40s. At this point, it looks like the front should get north of the Mass Pike and to at least Route 2 and possibly the MA/NH border. Whether it gets farther than that is debatable, or if it even gets that far. Another round of showers is likely Wednesday afternoon and evening as a cold front approaches. The warm front will also begin dropping southward again as a backdoor cold front. Temperatures will drop rapidly once that passes, so timing it correctly will be critical to the forecast. Most of the models have it move through during the evening or at night, but some have it as early as mid-afternoon.

Once the cold front moves through and temperatures start dropping, we could see a change to freezing rain and sleet across the interior late Wednesday night into early Thursday. Another low pressure system passes south of the region later Thursday into early Friday, which may produce some snow across the area, with accumulations possible, especially across the interior. High pressure then builds in for the weekend with drier conditions and seasonably chilly temperatures.
