Vehicle accidents were reported around Lancaster County after a mix of snow, sleet and freezing rain fell starting this morning.

By midday Wednesday, Lancaster County-Wide Communications said they had received reports of 30 vehicle accidents since 5 a.m.

Forecasts called for sleet and freezing rain in the morning. Up to 2 inches of accumulated sleet was possible in some parts of Lancaster County, according to Millersville University meteorologist Eric Horst.

By midday sleet started to changeover to rain, Horst said. Even with a temperature of 31 degrees in Millersville, the rain wasn't sticking, he said.

The frequency of weather-related crashes slowed as temperatures warmed slightly in the afternoon and sleet shifted into plain rain.

But with temperatures dropping this evening, Horst warned of ice on roads.

The National Weather Service in State College said a winter weather advisory for Adams, Fulton, Franklin, Lancaster and York counties will be in effect from 3 a.m. to 4 p.m. Wednesday.

Speeds on major roadways in South Central Pennsylvania were reduced to 45 mph at 5:30 a.m. In Lancaster County, that includes routes 283, 30 and 222. The speed reductions were lifted around 2 p.m., according to the Pennsylvania Department of Transportation.

“Snow and ice will result in difficult travel conditions, including during the morning commute … ,” according to the NWS.

Horst said he doesn't expect much snow accumulation in central Lancaster County, although 2 inches would be possible in the northern part of the county.

“Freezing rain midmorning into midday will result in some ice accretion, especially air-cooled surfaces like trees, powerlines, bridges, etc.,” he said in an email to LancasterOnline on Tuesday. “Salt-treated roads should be mainly wet during the midday/afternoon, but secondary roads and sidewalks, etc. will be slippery/icy into the afternoon."

Regionally, he said 3 to 8 inches could fall north of the Pennsylvania Turnpike with the potential for 8 or more inches in the northern part of the state.

Horst said the temperature will slowly rise from the 20s at dawn to between 32 and 34 in the afternoon. He said Wednesday night will turn breezy and colder with the temperature falling back into the 20s, “so a refreeze and some black ice will develop on we and untreated surfaces later in the evening and overnight.”

NWS dropped the winter weather advisory by Wednesday evening, but maintained a hazardous weather outlook for Lancaster County.

The outlook warns that slushy or wet untreated roads will freeze into a thin layer of black ice as temperatures drop into the 20s Wednesday evening.

The probability for widespread hazardous weather will be low Thursday through Tuesday, NWS said.

If you plan to travel to Philadelphia Thursday for the parade celebrating the Eagles Super Bowl championship, both AccuWeather and the NWS are calling for a mostly sunny day with temperatures in the lower 30s.
