The National Weather Service issued the bulletin in effect from 2 a.m. to 9 a.m. Friday for freezing rain, with total ice accumulations up to a tenth of an inch possible.

A cold snap that sent temperatures near historic lows brought record winter demand for electricity across numerous regional grids and service territories, including the Lehigh Valley.

“We’ve had about 13 customer calls for no water since Monday, with six of them coming in this morning,” Susan Sampson, LCA communications manager, said Thursday.

The wind chill was minus 11 on Tuesday morning, and a cold weather advisory remains in effect in the Lehigh Valley until Wednesday. With those temperatures, we're more like Buffalo and colder than parts of Siberia.

While the snow took a few hours to start piling up, by mid-afternoon it was falling at rates of two inches per hour in some parts of the Lehigh Valley. Dangerous cold will follow the snow, forecasters say.

Following a Winter Storm Warning, The National Weather Service at Mount Holly, New Jersey has now issued a cold weather advisory for the Lehigh Valley and surrounding areas, warning of "dangerously cold" temperatures this week.

Depending on how the system evolves, a robust and plowable storm seems like the more likely scenario for the region, with the timing on potential snowfall beginning to lock in for Sunday afternoon.

Confidence has increased for a clipper system to bring light snow to the region on Thursday, with potential for additional accumulation Sunday into Monday. The coldest air mass of the season arrives behind it, forecasters say.

Delta flights to and from Atlanta were among those impacted at Lehigh Valley International Airport on Friday.

Just like Monday, which offered little in terms of intense snowfall, Saturday’s wintry weather could essentially be a “non-event” for much of the Lehigh Valley and the rest of the region, the National Weather Service said.

The latest snow storm has shifted south, meaning the area should see a few inches of snow from early Sunday morning into Monday. Surrounding areas are expected to experience hazardous travel conditions.

With the system three days away, the weekend will serve as the calm before the storm, with questions remaining on exactly where it will track and how much snow will fall across the region.
