    We are done with the record cold.

    The last time we had two days in a row this cold in November was way back on Nov. 23 and 24, 1938.

    Now we actually have close to seasonable weather. The average high temperature for Boston this time of year is 49°; we may get close to that tomorrow and Sunday.

    The strong cold high pressure system is moving south of us overnight, with one more night of freezing temperatures in the teens and 20s north, to 20s south. A few areas in Maine with snow on the ground may get down below zero once again. Several hours of sunshine Saturday morning, followed by increasing clouds. A warm front in New York will bring rain into western New England after the sun goes down. Moving into eastern New England at midnight. Though the air may warm-up, the ground is still very cold so icy spots may be developing.

    Low pressure will be strengthening from Long Island to Nantucket early Sunday, with rain heavy at times along the South Coast at sunrise. We also have the possibility of damaging wind from the east gusting past 50 mph, with coastal flooding also possible. As we move north Sunday, weather improves to mostly dry near the Canadian border.

    However, in parts of Maine, along the turnpike, there may be enough rain and cold air to cause some freezing rain for a few hours.

    For most of us the high temperature on Sunday is in the 40s, if we get any sunny breaks in western New England we could reach the lower 50s, otherwise patchy fog and drizzle with an onshore flow may keep us in the low 40s. We tend to dry out a bit Sunday afternoon and overnight, but another batch of rain and wintry mix will arrive during the day Monday.

    It’s a tough call as to whether we’re going to have rain or snow, as the air is going to be getting colder Monday afternoon and especially Monday night Tuesday. The likely outcome is rain changing to snow in the mountains Monday, otherwise cold rain near the coast Monday night. Then depending on the storm‘s position, we may have rain changing to snow all the way to the coast Tuesday, as temperatures cool back down to the 30s. This all bears watching, is tides are running pretty high with the full moon, and we are vulnerable to some coastal erosion and minor flooding. The second half of next week looks like cold and dry weather returning.
