Weekend Starts with Snow, Rain for New York, Philadelphia

After a relatively quiet end to the week, a weak Alberta Clipper will spread a sloppy wintry mix across the mid-Atlantic, meaning a soggy Saturday for some and a snowy day for others.

While the precipitation will be light, the snow could lead to slick roadways around Altoona, Pa., and Johnstown, Pa., on Saturday morning as temperatures hover around the freezing mark.

Although many lower elevations across interior Pennsylvania will struggle to get an inch of snow, up to 2 or 3 inches of snow may accumulate across the higher terrain of western Pennsylvania.

Travelers heading north or east out of Pittsburgh on I-79, Route 22 or the Pennsylvania Turnpike should be ready for some slippery spots across some of the higher elevations, even though the majority of the road may be just wet.

By the time the snow moves eastward into Scranton, Pa., and New York City by the midday and afternoon hours, temperatures will be above freezing and roads should remain wet as the snow falls lightly.

Farther south, while a few wet snowflakes could mix in around Philadelphia, mostly rain is expected. Rain will also dampen outdoor plans around Baltimore and Washington, D.C. Even though the rain will not be heavy, it will feel damp and chilly as temperatures do not get out of the 40s on Saturday afternoon.

While the morning hours may turn out mostly dry, it will be a chilly day for the St. Patrick's Day parade in New York City on Saturday, with highs only in the 30s with some flurries or even a bit of snow possible by the end of the parade. The parade in New York City is one of many going on around the country this weekend.

While the northern half of the mid-Atlantic will be dealing with a cloudy, chilly day, warmer air will not be too far away. Temperatures around the Washington, D.C., area may not reach 50, but temperatures will sneak into the 70s across southern Virginia with the sun breaking through the clouds at times.

With temperatures being higher, there could be enough instability to allow a few thunderstorms to develop from near Norfolk, Va., down towards the Virginia/North Carolina border on Saturday afternoon. Any thunderstorm could contain strong, gusty winds.

As the clipper moves away, chilly air will remain in place across the mid-Atlantic into Sunday. While many will remain dry, some rain could arrive in the Nation's Capital by the end of the day.

That rain will mark the outer fringes of a developing storm in the Mississippi Valley. This storm will produce a messy wintry mix in the mid-Atlantic on Sunday night and Monday.
