The season’s first accumulating snow and coldest weather so far will be accompanied by some biting winds today, AccuWeather meteorologist Brett Anderson said.
“It is going to be pretty nasty Tuesday,” Anderson said Monday night.
Snow was expected to begin after midnight and continue through the day today and tonight.
Accumulations of about an inch in Johnstown and 3 inches in the surrounding hills are expected, Anderson said.
Somerset County’s higher elevations could receive 4 or more inches.
“We are looking at an arctic air mass coming in (Monday night) to enhance snowfall,” he said.
The brunt of the snow is expected to hit areas northwest of Pittsburgh, including the Youngstown, Ohio, area, he said.
Temperatures will struggle to break 30 today, and drop into the low 20s tonight.
Winds out of the northwest will have gusts approaching 30 miles an hour today, making it feel 10 to 15 degrees colder, Anderson said.
The worst of the cold snap will be short-lived, he added.
“The coldest air starts to shift away from the region on Wednesday,” Anderson said. “There will be less wind and more sun.”
On Thursday, it will get back into the 40s, with mid-50s by the weekend.
“It is a nice, steady warming trend,” Anderson said.
