What to expect from Pennsylvania’s first winter storm of the season

As Pennsylvania prepares for its first snowfall of the season, the National Weather Service is calling for heavy accumulation in parts of the state.
Although central Pennsylvania isn’t forecast to receive much snow at all, places like Scranton, Johnstown, Wellsboro and the Laurel Highlands could see upwards of 6 inches.
“Much less snow is expected across the Lower Susquehanna Valley, where amounts will range from just a few flakes to a few tenths of an inch,” a NWS Facebook post said.
Harrisburg’s forecast calls for some rain and snow before 4 a.m. Friday with a low of around 33 degrees. By Friday morning, rain and snow are expected after 11 a.m. with a high of 43.
Forecasters are predicting less than a tenth of an inch of snow in areas including Harrisburg, York and Lancaster. By Friday night there will be a slight chance for rain before temperatures rise into the low 50s and winds gust upward of 25 mph on Saturday and Sunday.
PennDOT proactively treated roadways with salt leading up to the storm, but recommends avoiding travel during the winter weather if possible.
Two Tier 1 vehicle restrictions also went into effect at 5 p.m. Thursday on I-81 north of I-380 and the entire length of I-84.

From Thursday evening into Friday morning, PennDOT is also advising drivers of possibly heavy snowfall between New Stanton and Bedford.

PennDOT recommends avoiding unnecessary traveling during the storm. However, if you have to drive it is important to have supplies — such as food, water, blankets, warm clothes, a cell phone charger, necessary medications, baby/pet supplies — in your vehicle before you leave.
