After a relatively quiet end to the week, a weak Alberta Clipper is invading the mid-Atlantic, meaning a snowy start to the weekend for some and a soggy day for others.

The snow has been tracking from the Detroit area to central Pennsylvania this morning, accumulating a few inches and creating slick travel.

The snow fell heavy enough to overcome the strong March sun and led to widespread accidents throughout Jefferson County, Pa.

The snow, with a bit of rain falling to the south, will continue to press eastward across Pennsylvania and into New Jersey and New York City.

However, roads should remain wet east of Interstate 81 as temperatures hold above freezing and the snow falls lightly this afternoon and evening.

Farther south, while a few wet snowflakes could mix in around Philadelphia, mostly rain is expected. Even though the rain will not be heavy, it will feel damp and chilly as temperatures do not get out of the 40s this afternoon.

Rain will also dampen outdoor plans at times around Baltimore and Washington, D.C.

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., will climb into the middle 50s as temperatures 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 this 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.
