The National Weather Service reported between three and four inches of snow fell on Northumberland County overnight Tuesday into Wednesday, marking the fourth measurable snowfall in the last four weeks.

Snow, and at times a wintry mix, began falling at about 10 p.m. in most parts of the county, but tapered off by morning rush hour. After the snow stopped, plowing crews got to work and major highways were clear and mostly wet by 8 or 9 a.m., according to a county PennDOT official.

However, the storm did prompt schools to call for two-hour delays, while Danville and Southern Columbia were among local districts that canceled classes for the day.

The National Weather Service (NWS) had issued a winter weather advisory Tuesday until 11 a.m. Wednesday, and meteorologist Craig Evanego predicted Tuesday the storm would be "a little more than a nuisance."

Snow fall amounts were consistent throughout the area.

"Our co-op reporter said 3.6 inches fell in Sunbury, while areas like Tamaqua and Mahanoy City had between four and 4.2 inches," Evanego said. "Williamsport checked in with about four inches, so it was pretty much the same across the board."

A foot so far

The latest accumulation adds to the nine inches of precipitation and snowfall the area has received so far this season, according to Evanego.

About two inches fell on Christmas Eve, another two inches fell on Dec. 26. Three to five inches of snow accumulated in the area Dec. 29.

PennDOT trucks pre-treated some of the area's major routes with anti-icing solution before the first flake fell Tuesday. The process involves wetting the highway with salt brine, a solution that lowers the freezing point of water and slows or prevents ice from forming a bond with the pavement during the early stages of a storm.

Department officials remind motorists that the pre-treatment is not a "silver bullet" in winter weather, but it gives crews an edge at the start of a storm.

Mount Carmel Borough officials are asking residents to remove their vehicles from Oak Street between 6 and 8:30 a.m. so that street crews can remove snow from the thoroughfare.

Cold, then real cold

As for what's to come, Evanego said, "We aren't seeing any significant storms for the rest of the week. We have a bit of a cool down once this system goes through."

A cold front will make it chilly today into Friday and then warm up Saturday, when temperatures will be in the 40s, he predicted.

Next week's concern won't be falling precipitation, but falling temperatures.

"The big weather story next week will be a steady period of normal winter temperatures," Evanego said. "We have high temperatures in the 20s and overnight lows in the teens with some colder air on the way."

With snow on the ground, it could get even colder.

"The snow will help temperatures drop, so by around Wednesday, Jan. 23 and Thursday, Jan. 24, it could be a struggle to hit a high of 20 degrees and lows overnight could drop to single-digit level," the meteorologist said.
