Winter blast coming; Sunday may be slippery

Get the fireplaces ready, heaters prepared and winterize the car.

A winter blast of ice cold air hits the region starting today, bringing enough sunshine to clear out Friday night’s snow and sleet accumulation, before another round of snow, sleet and freezing rain targets Williamsport and the region Sunday afternoon.

“We’ve had an Arctic air mass that snuck into the region,” said Craig Evanego, a meteorologist with the National Weather Service in State College.

While today should be partly sunny it’ll be cold for holiday shoppers, with highs reaching into the low-30s.

“We should see snow tappering off around pre-dawn this morning, with skies becoming partly sunny but it’s going to be chilly and continue cold throughout the remainder of next week,” he said.

Saturday night the clouds increase with a low of about 20 degrees, he said.

“We’re probably going to see snow developing Sunday afternoon, with a high temperature in the 20s,” he said.

Sunday night remains cold and the snow switches over to sleet or freezing rain. It could cause “black ice” slippery conditions on highways, he said.

Next week also looks to remain in the 20s and teens at night.

For the start of the school and work week, Monday holds a chance of rain, but much warmer than the weekend, with a high near 40. There is a chance of snow Monday night, with a low about 23.

For Tuesday through Thursday, it remains much colder than Monday, with high near 25 Tuesday and a low that night forecast at 11.

It remains frigid Wednesday, with partly sunny skies but a high of 24. That night, the temperature drops into the teens. Thursday will be mostly sunny, with a high near 23.
