A storm system that stretches from south of Florida to north of Newfoundland that has soaked the eastern coast of the United States is now pushing offshore with a snowstorm on its backside.
There have been many reports of ice jamming on rivers, causing water to come up and flood roadways here in New England.
Torrential downpours Friday night generated three inches or more of rainfall in some locations. At the same time, record temperatures near 60 degrees made for melting snow and the rapid rise of rivers, along with ponding of water on the roadways and probably a lot of flooded cellars, as the ground is frozen so rainfall run-off cannot be absorbed.
The beginning of the end of our thaw starts with much colder air moving into Vermont with a snowstorm Saturday morning. In New Hampshire and western Maine, there will be freezing rain.
Low pressure tracks right over southern New England Saturday morning, so the rain, ice, and snow will shut down by midday, but not before we get a bunch of snow in Vermont, freezing rain in central New England, and perhaps a flash freeze of flooded areas in southern New England by midday.
Wind from the south, ahead of the low pressure, will generate wind gusts up to 50 mph in southeastern New England where a wind advisory is now expiring.
Temperatures start the day near 50 degrees in southern New England, cooling rapidly into the 20s south by midday. It will start in the 20s north and fall into the single numbers by sunset.
The Patriots will host the Titans under a clearing sky, though a few snow flurries are possible, with the temperature in the lower 20s.
Sunday should feature plenty of sunshine, though clouds may linger in eastern New England. Some snow flurries in eastern Massachusetts and eastern Maine are possible. Highs will be in the teens north to 20 south.
Martin Luther King Day on Monday gives more sunshine, but we still may have snow showers in parts of eastern Massachusetts. Otherwise, it's a dry start to the week with the high in the 10s and 20s.
A push of even colder air will be working into the Great Lakes with low pressure developing over the Midwest Monday. That storm is expected to reach the Atlantic Ocean and intensify right over New England on Tuesday. There are some signs that the storm may try and stall here, for a prolonged snow and/or rain event.
We should be cold enough that it would be mostly snow, though a rain/snow line is possible, especially from Boston to New York City.
If that does evolve into a multi-day storm, obviously it would leave a lot of snow in the mountains of New England, but we have to keep an eye on it because it is still pretty far out there and we have to get through this one first.
