A weak cold front pushed into southern New England Wednesday night. Other than a little coating of snow in Vermont, the only change is that it's a little bit colder in central and northern New England on Thursday. A strong high-pressure system slowly moves across Maine, which means light wind and a good amount of sunshine.
High temperatures in the 30s to near 40 degrees along the south coast, to only the teens and 20s in northern New England. High clouds increase Thursday afternoon, but no weather problems through at least early evening.
The storm responsible for severe weather from Texas to Ohio, and a blizzard in the northern plains states, arrives here after midnight. Because air flows around low pressure in a counterclockwise circulation, we'll warm up if the storms pass to our west. That is the case for us for Friday.
The temperature Thursday night does get below freezing, even down to the single numbers and parts of Maine. But the warmer air will start coming in after midnight. Those are mostly in the teens up north in the 20s to low 30s down south.
With an initial cold air mass in place, as precipitation arrives, we are cold enough for snow in most of New England.
A rapid change to rain will happen in Connecticut and Rhode Island, but it will be a slower transition from northern Massachusetts and points north.
From about the Pioneer Valley and points north and east of the Massachusetts Turnpike, we have a few hours of icy conditions on side roads and untreated surfaces Friday morning.
For most of southern and western New England, the temperature gets close to 40 degrees before lunchtime.
But in eastern New Hampshire and much of Maine, it’s a slower transition. Roads will become quite slippery during the morning into the early afternoon.
By afternoon, all but eastern Maine warms above freezing with periods of rain and fog with increasing wind from the south.
Rain will taper to showers late in the day, with high temperatures ultimately in the 50s south and west, to 30s and 40s north and east.
There will be a partial clearing Friday night with a low temperature in the 30s north and 40s south. A cold front swings through on Saturday, but we should have several hours of sunshine and mild air in southern and eastern New England with a temperature near 50 degrees.
In higher elevations of western Massachusetts and Vermont, it’ll become windy with snow showers. Temperatures will be falling into the 30s late in the day.
It’s a very challenging forecast thereafter.
It looks like low pressure may miss us to the south Sunday, leaving us with a good amount of sunshine and cold air with temperatures in the 20s north and 30s south. Additional weather is going to approach on New Year’s Eve day Monday, increasing clouds with a chance of rain or snow late in the day.
There is still some chance we stay dry for New Year’s Eve, but there’s also the possibility that we get a chilly rain or some snow. The same with the days following, the chance of rain or snow pretty much every day next week, but we can’t tell exactly when or how much just yet.
