Weekly Outlook: December 13-19, 2022

Colder weather has arrived, and more is on the way, but so is some rain.

The week starts off with low pressure pulling away from the region, with any lingering snow showers ending this morning, then skies start to clear out as high pressure builds in. Clear skies, lighter winds, and some fresh snowcover will result in radiational cooling tonight, with many places dropping into the teens. High pressure remains in control on Tuesday with sunshine and cool temperatures. An upper-level disturbance moves through on Wednesday, and it may be accompanied by some snow showers, especially along the coast. Even colder air settles in behind it for Wednesday night.

Clouds start to stream back in on Thursday as low pressure begins to head toward the region from the Southwest. For most of the region, this looks like a rainstorm for Thursday night and Friday, but a period of snow or wintry mix to start across parts of central Massachusetts and southwestern New Hampshire. However, this is still 4-5 days away, and a lot can change between now and then. Even small changes to the track that the low takes can have a big impact on the forecast. A track farther south and/or east could result in in wintry weather for a larger portion of the region and potentially for a longer period of time. We’ll be keeping a close eye on this as the week goes on. Behind the storm, cooler and drier weather returns next weekend.

Friday looks rather unsettled, but there are still plenty of details to work out. Images provided by Pivotal Weather.
