    Cold Air Protecting Us From Storms

    Wednesday: Increasing clouds. Highs in the 30s. Wednesday Night: Partly cloudy. Lows in the teens and 20s. Thursday: Mix of sun and clouds. Highs near 40. (Published Wednesday, Dec. 5, 2018)

    With high-pressure cresting over us Tuesday night as the wind eased, our temperatures fell to 10 to 20 degrees in southern New England, about 25 degrees at the south coast, and close to 0 degrees at the Canadian border.

    As high pressure moves into the Gulf of Maine, a light breeze develops off the ocean, perhaps with a little bit of chance of light snow or flurries south of Boston to Cape Cod in the islands. Otherwise, we have sunshine fading behind clouds as a warm front approaches from the west Wednesday. High temperature near 32 degrees.

    The warm front is weakening over us Wednesday night, but a bit of a breeze from the southwest. More clouds will keep us less cold, and the low temperature will generally be in the 20s to lower 30s to start Thursday. A few spots may touch 40 degrees in slightly warmer air Thursday afternoon before an arctic front approaches late in the day.

    This next front moving in from Canada Thursday night will generate snow showers and snow squalls in western and northern New England, and maybe a flurry all the way to the coast early Friday. During the day Friday, wind increases and the temperature falls out of the 30s into the 20s south, out of the 20s into the 10s north, with wind gusting past 30 mph.

    Friday night and Saturday are a lot like what happened the Wednesday before Thanksgiving and on Thanksgiving day, very cold but cleaner air comes in with temperatures in the 10s and 20s to start the weekend.

    At that time, a storm will be impacting that southeastern states, there may be quite a snowstorm in western South Carolina and North Carolina! That’s storm likely misses us to the east Monday, but keeps on the cold side into early next week.
