An arctic cold front will slide through overnight, bringing a two-day shot of brutally cold air and wind chills that may drop as low as zero to five below Thursday night.

DePrest said there could be potentially damaging winds, and risky wind chills.
Check back with Portsmouth Press later in the week for more details. Temperatures are colder in the lower to middle 30s, but in the wake of Wednesday’s system is a more potent blast of Arctic air!
Periodic snow squalls are possible Wednesday afternoon, according to the weather service.
The good news is any precipitation will end over much of the state by early Sunday afternoon. The fresh snow and clear sky allowed thermometer readings to drop into the single digits.
“Winds will gust to 30-40 miles per hour with gusts up to 50 miles per hour possible”.
Winds will initially be light and variable through late Wednesday evening.
Thursday: Scattered snow showers, mainly before 1pm. Today’s high will be right around the mid-December normal of 43 degrees, but that is not going to be the case tomorrow. We have experienced a few glancing blows of Arctic air, but the center of the cold has remained well to our north across the Upper Midwest so far.
Lows: Temperatures in the teens and 20s below zero will infiltrate areas from Montana to the Dakotas and the upper Mississippi Valley this weekend.
Friday: Morning wind chills -20 to -10.
This is risky cold, folks. For the record, I don’t use that phrase unless I mean it. Frostbite can quickly affect exposed skin in such conditions, and hypothermia can be life-threatening in a surprisingly short period of time.
An arctic blast is on its way to the New York City area, bringing frigid temperatures to the region by Thursday morning.
Some of the heaviest snow over this busy travel weekend is expected between Minneapolis and Buffalo. “And Saturday night, we’re looking at 10 below”.
Another cold front slices through later Sunday with colder temperatures to start next week. If the storm takes a track further south then higher snow accumulations will be possible. That will cause a transition from snow to rain.
“It’s going to be unsafe”, he said.
Saturday: Snow before noon, then snow and freezing rain between noon and 1pm, then rain likely after 1pm. A band of snow should begin to spread across southern NH after midnight Friday night and Saturday morning most everywhere else.
Get ready for the coldest temperatures in central in since last February as you head out this morning. Rain showers are expected on Sunday with highs once again in the 40s. It is worthy to pass along the highs of the day will come around midday, with temperatures heading for the cellar from 1-2 PM on.
