Astronomical winter doesn’t start for a few more weeks, but Mother Nature is giving us a preview this weekend.
An arctic cold front crossed the region this evening, producing some snow showers and squalls as it moved through. Behind it, much colder air is going to settle in tonight on gusty northwest winds. By Friday morning, temperatures will be in the single numbers and teens across most of the region, with some subzero readings possible in areas with fresh snowcover. Despite some sunshine on Friday, temperatures will only get into the 20s and lower 30s as winds die down, but clouds will quickly return ahead of another weak system. That system will pass south of the region Friday night and early Saturday, keeping the bulk of the precipitation offshore, but a trough extending from the system may produce a few snow showers. Across eastern Massachusetts and Cape Cod it should be mild enough for rain showers instead We’ll clear out Saturday night, then Sunday should be a decent day for early December, but another strong cold front moves through at night. This one will also produce some snow showers, and behind it we’ll turn rather cold again behind that front on Monday.
