Bethlehem Live Weather Camera

December temperatures in the Lehigh Valley have plunged far enough below normal to make even seasoned winter residents take notice.

The Lehigh Valley is under a winter weather advisory for 2 to 4 inches of snow. But could it see more?

After a wintry blast on Wednesday that dropped as much as 3.1 inches of snow in parts of the area, forecasters say more could be coming this weekend.

A fast-moving system could bring another round of light snow or a wintry mix to the Lehigh Valley on Wednesday, forecasters say.

Meteorologist Bobby Martrich of EPAWA Weather Consulting highlighted the area as one to watch, thanks to the setup of a “thermal gradient” or baroclinic boundary as the storm moves through.

The Lehigh Valley is under a winter weather advisory from 4 a.m. to 1 p.m. Tuesday, with total snow and sleet accumulations of 2 to 5 inches expected, with the greatest amounts at higher elevations.

The Lehigh Valley is in line for potential snowfall Tuesday as a coastal storm takes aim at the region, but there's a lot of uncertainty at this point," forecasters say.

Customers should understand that generation/supply typically make up 40% to 60% of a utility bill, the PUC said, with variables such as weather, usage and efficiency of a home heating system factoring in.

The Chicago area was digging out last week after a band of lake-effect snow buried the Windy City, dropping up to a foot in some areas. Could the Lehigh Valley be far behind?

Current conditions, along with the continued drying of fine fuels, "could support the rapid spread of any fires that ignite, which could quickly become difficult to control," the National Weather Service said.

Following a wind advisory Wednesday night, forecasters say the Lehigh Valley will see a fairly active pattern continuing through the weekend and into early next week as temperatures tumble.

A wind advisory goes into effect at 10 a.m. Friday for much of eastern Pennsylvania and northern New Jersey, as strong westerly winds sweep through the region.
