More Snow Coming: 2 – 4 Inches Possible Overnight

Those winter storm warnings aren’t going anywhere fast. They’ll stay posted through 5 a.m. Friday as, yes, another round of snow is expected to hit the Mid Atlantic tonight.

An additional two to four inches of snow could fall before 2 a.m., and it’s coming from a another low pressure system making its way north form the Gulf Coast.

The low pressure system that brought us about a foot of snow in many places has moved off the coast of Norfolk out to sea, according to the National Weather Service.

Afterward, we saw temperatures in the region rise, and a perception changeover from snow to sleet and rain. That caused a light glaze to form on cars and on the snowpack on the ground.

Here’s more about the next system that could bring us more snow, from the National Weather Service.

THE UPPER LOW THAT WILL PIVOT NORTHWARD AND MOVE ACROSS THE MID ATLANTIC WILL BRING ANOTHER ROUND OF SNOW TO THE AREA. NAM AND GFS ARE BOTH SHOWING MID LEVEL CONVERGENCE MOVING ACROSS THE REGION FROM WEST TO EAST.

HEAVY SNOW ACROSS NW MD…WEST VIRGINIA AND ACROSS THE CAROLINAS IS GOING TO MOVE TOWARDS THE MID ATLANTIC THIS AFTERNOON AND EVENING. WRAP AROUND MOISTURE FROM THE SFC LOW AND STRONG LIFT AND DYNAMICS FROM THE UPPER LOW WILL LEAD TO ADDITIONAL ACCUMULATIONS. HRRR AND WRF ALSO SHOW THIS ACTIVITY CROSSING THE AREA.

THERE ARE SOME DIFFERENCES IN THE AMOUNT OF MOISTURE EXPECTED BUT AN ADDITIONAL 2-4 INCHES WILL BE POSSIBLE FOR THE MID ATLANTIC. MOST WINTER WEATHER WARNINGS WILL CONTINUE TO COVER THE SECOND ROUND OF SNOW THAT IS EXPECTED THROUGH TONIGHT.

AS PRECIP ENDS ACROSS THE I-95 CORRIDOR AROUND DC THE WINTER WEATHER WARNING WILL DROP THIS AFTERNOON.A WINTER WEATHER ADVISORY HAS ALREADY DROPPED IN FAR SOUTHERN MARYLAND. A DIFFERENT WINTER WEATHER ADVISORY IS IN EFFECT LATE THIS AFTERNOON THROUGH TONIGHT FOR I-95 AND EAST.
