The National Weather Service has issued a winter weather advisory for Lehigh, Northampton and Berks counties for 2 to 4 inches of snow from 7 p.m. Saturday until 7 a.m. Sunday.

Snow should begin across the region by 8 p.m., according to the weather service’s storm briefing issued Saturday morning. However, the heaviest snowfall is expected after midnight.
The weather service said it has moderate confidence in its snow forecast totals, with around an 80% chance of at least 1 inch of snow or more falling across the Lehigh Valley. Snowfall amounts are expected to increase as you head south and east of the Lehigh Valley, with Philadelphia in the 3-5 inch range.
Snow will lead to slippery road conditions during the storm, and motorists should use caution, according to the advisory.
The brunt of the snow should wrap up by daybreak Sunday, however, snow showers could linger through the morning.
After the snow moves out, bitter cold is expected to move in, with wind chills Sunday night dropping into the low single digits in the Lehigh Valley and below zero in the Poconos. During the day, winds could gust up to 30 miles per hour, according to the weather service.
