Monday morning storm update

The latest winter storm to intrude on our transition to Spring has started with a burst of snow in Washington, DC, now moving through Baltimore and may reach as far north as central New Jersey.

We are awaiting the formation of a secondary storm off the Maryland/Delaware coast. Indications are that the storm will stay just far enough off the east to limit accumulating snow in the NYC/Long Island/New England area to the coastal areas, with little accumulations inland. Even at the coast most of the snow will just stick to grassy surfaces.
Roads should be mostly clear, but watch out when you drive over overpasses and bridges that may be slick as the falling snow chills the overpasses.

Check your NWS local forecast for details and updates!

After the storm, high temperatures go to the mid-40s, and 50’s by the weekend, warmer than the last few weeks, but still cooler than normal.

Tech details from the NYC forecast discussion:
THE NAM MAINTAINS A RATHER SHARP GRADIENT KEEPING
MOST OF THE PRECIPITATION OFF THE COAST. WHILE THE GFS AND ECMWF
BRING HIGHER QPF [precipitation] ACROSS LONG ISLAND AND THE CITY. STILL EXPECT
AROUND A HALF INCH LIQUID WITH 2 TO 3 INCHES OF WET SNOW. WILL KEEP
THE ADVISORY IN PLACE FOR TODAY AND TONIGHT. LESS CONFIDENT THAT
NORTHWESTERN PORTIONS OF THE ADVISORY…IE..WESTERN NEW
JERSEY…WILL SEE ADVISORY LEVEL SNOWFALL [2 inches or more].
BEST FORCING WILL BE
ACROSS NEW YORK CITY AND LONG ISLAND…WITH LITTLE FARTHER TO THE
NORTH. INLAND AREAS MAY SEE LESS THAN AN INCH OF SNOW…SO WILL NOT
EXPAND THE ADVISORY FROM CURRENT AREAS.

WILL BECOME WINDY AS THE LOW NEARS THE AREA LATE THIS
MORNING…HOWEVER WINDS WILL LIKELY REMAIN BELOW ADVISORY LEVELS
WITH THE HIGHEST WINDS RIGHT ALONG THE SOUTH SHORE OF LONG ISLAND
AND INTO NEW YORK CITY WITH MAX GUSTS 40 TO 45 MPH.

  1. Wrap-up: The storm got it’s act together off the Delaware coast, but it stayed just enough south to keep the heavy snow to the south of NYC. Now the jet stream has unkinked itself enough to scoot it out to sea. Also, the storm took so long to get going that the spring-time sun, even through thick clouds, was enough to keep the precipitation mostly rain inland. – bob
