Local meteorologists are predicting “plowable snowfall” from Sunday night into Monday morning, as a nor'easter is expected to dump 3 to 6 inches of snow across the region.
Forecasters are warning of slippery travel Sunday night, and a possible slower Monday morning commute for those working on the holiday.
“The most likely scenario is 3 to 6 inches of snow for Sunday night, with the caveat that we still have a moderate amount of uncertainty for the higher-end amounts,” Bryce Williams, meteorologist at the National Weather Service's Boston office, told the Herald on Friday.
There's also a low probability for a swath of more than 6 inches of snow.
Meteorologists are closely watching the track of the nor'easter — whether the storm is closer to the coast or farther away from the coast.
The track will ultimately determine whether the region will be dealing with a rain/snow line.
“We're trying to nail down the track,” Williams said.
There were still considerable differences between the forecast models on Friday, as the National Weather Service cautioned that the “forecast is not set in stone.”
“While no solutions can be ruled out at this point...we are favoring the GEFS/EPS Ensembles along with the UKMET that support a middle ground with the wave of low pressure tracking near the Benchmark,” the National Weather Service's forecast discussion reads. “This solution would bring a period of accumulating/plowable snowfall which may start as a brief period of rain. A very preliminary snowfall forecast indicates that 2-6″ of snow is possible across a good portion of the region.”
There was still a low risk for little if any snowfall if the storm track trends east or a far western solution, which would support mainly rain on the coastal plain.
Following the snowfall, a brutal arctic outbreak will descend upon the region from later Monday into Wednesday — with wind chills likely dropping to between 10 and 15 below zero.
The actual low temps on Monday night and Tuesday night will be in the single digits, with some below zero.
The actual high temps on Tuesday and Wednesday will only be in the mid-teens to low 20s.
This will likely be the coldest weather since early February 2023. The National Weather Service is warning of “bitterly cold air.”
“Blustery Northwest winds will probably drop Wind Chills into the -10 to -15 below zero,” the National Weather Service's forecast discussion reads. “Cold Weather Advisories will likely be needed.”
