BOSTON We have fog, warmth and then more frigid weather all on tap in the next 24 hours. Some heavy downpours of rain and fog will slow down the Monday morning commute as our snowpack shrinks. During the day more showers will pass through. For the evening commute, the last batch of showers will be ending so I expect fewer weather issues on the ride home.
After 8 p.m., temperatures will have fallen below freezing so any slush that is left will freeze to a rock solid mass. Icy patches could develop on some roadways, but winds are going to be strong enough to dry the roads at the same time the cold air is rushing in to the area. This will greatly lessen the chances for any significant ice issues overnight.
You have no doubt heard about the extreme cold in the Midwest. A piece of that cold will clip New England the next few days, but the core of the coldest air will stay west and south. Cold dry weather is in the forecast for the Tuesday and Wednesday when highs will be in the teens on Tuesday and upper teens and lower 20s on Wednesday. This cold snap won’t be as cold as the post snowstorm air when many areas saw temperatures fall below zero and wind chills reached 20 below.
Later this week, the jet stream retreats north and takes the arctic air along with it. A “January Thaw” pushes into the area for the weekend. We will be above freezing by Friday and even milder for the weekend. That will continue into the early to mid-part of next week.
Monday: Shower, maybe even the rumble of thunder and dense fog. The fog will cause some travel issues this morning. Highs near 50 during the morning, but falling to around 40 by dark.
Monday night: A brief snowshower late at night, otherwise partly cloudy, blustery and turning very cold. Lows 10-15, 15-20 on the Cape and Islands.
Tuesday: Lots of sunshine, blustery and cold highs in the teens. Wind chills 5 above to 15 below, coldest in the morning.
Tuesday night: Generally clear and frigid, lows in the single digits. Wind will bring wind chills into the -7 to -15 degree range at times.
Wednesday: Sunny, with a highs in the upper teens to mid 20s.
Wednesday night: Partly cloudy, with a lows 5-15.
Thursday: Partly sunny, with a high near 30-35.
Thursday night: A chance of snow showers. Mostly cloudy, with a lows 17-23.
Friday: A chance of snow showers, little or no accumulation expected. A bit milder, highs in the 30s.
