Weekly Outlook: January 10-16, 2022

Dig out the thermals and heavy winter gear, some really cold air is on the way.

Temperatures will turn colder today despite some sunshine, but this is just the opening act for what is on the way. An arctic cold front will cross the region this evening. It may produce some snow showers or squalls, so if you’ll be out this evening, be prepared for a short burst of snow that could significantly reduce visibility and drop a quick coating on the roads. Once the front moves offshore, bitterly cold air will flood into the region for Tuesday and Tuesday night. Temperatures will drop below zero in parts of the region Tuesday morning. Despite plenty of sunshine Tuesday afternoon, highs may struggle to reach the lower teens across most of the area, with wind chills that are below zero. Across Cape Cod, there may not be as much sunshine, as northwest winds blowing over the relatively mild water of Cape Cod Bay could produce some ocean-effect snow showers, especially across the Outer Cape. We’ll have another bitterly cold night Tuesday night, with subzero lows possible once again, but as high pressure slides off to the east on Wednesday, temperatures should start to moderate. It’ll still be chilly, but highs should get into the 30s across the area.

Temperatures will turn colder again for the end of the week, but there are bigger concerns. We’ve cautioned you recently that the models have performed rather poorly beyond 2 or 3 days, and that is still the case, so this part of the forecast is highly uncertain. However, many models are showing the potential for a powerful ocean storm to develop late Thursday into Friday, and a second storm to do the same over the weekend. The fact that they all show this gives us a little more confidence that they both may actually develop. The problem is, that’s about all they agree on. They don’t agree on the timing of the storms, the track they might take, how strong they’ll get, and what, if any, impacts they may have up here. These are things that we’ll be keeping a close eye on as the week goes by, but for now, what you read below is our “best guess” (for lack of a better term), but it is very low confidence.

The models all have different ideas about a potential coastal storm on Sunday. Images provided by Pivotal Weather.
