Milder Air Moves Into Place Before Rain Arrives

After days of a deep freeze, we'll thaw out for a couple of days with heavy rain arriving Thursday

The high-pressure system responsible for frigid weather the last 48 hours is now to our south. Thanks to clockwise circulation around the center of the high, we get incoming wind from the southwest. This should push temperatures to 40 to 45 degrees south, in the 30s north today.

In addition there is low pressure system traveling through the Great Lakes with its attendant warm front crossing New York into Western New England.

This means we get a little bit of snow in the mountains in the far north, with a chance of sleet or rain from western Massachusetts to southern Vermont and New Hampshire. There is a winter weather advisory for this wintry mix in western and northern New England today and tonight.

For most of us it’s going to be a partly to mostly cloudy day with a high temperature above freezing, and not too much wind. Temperatures actually go up a bit overnight tonight, with any wintry mix changing to rain north, and rain developing south.

Thursday features a wet start with rain briefly heavy especially in southern New England. Rainfall amounts exceeding one inch, combined with frozen ground and a saturated snow pack may result in localized flooding in southern New England. Further north the snow pack is dry enough to absorb the rain.

Dense fog also becomes an issue, and wind from the south may gust past 40 or 50 mph in southeastern New England. High temperature in the 50s south and 40s north. Colder air comes in from the west as we dry out tomorrow afternoon, perhaps a change back to snow in the mountains west before ending.

Temperatures fall below freezing at night, but with a chance for many of the puddles to evaporate before freezing. But there still may be patchy black ice to start our Friday, with the temperature in the 20s south and teens north.

Another front comes at us from Canada late Friday with a chance of snow showers west and north, otherwise the sun and cloud mix, with a high in the 30s south and 20s north. Saturday looks like a mix of sun and clouds colder, with a few flurries possible, high temperature in the teens north and 20s south.

A quick moving disturbance may bring a period of snow or mix Sunday, at this time it does not look big, high temperature in the 20s and 30s.

It’s a very challenging forecast next week is an active jetstream separates warm air off the coast and very cold there across the Midwest, it will not take much for us to get a more significant winter storm in the Monday to Wednesday time-frame. We will keep you posted here in our first alert 10 day forecast.
