Discussion

The real "March Madness"...signs continue to point to the threat for a strong coastal storm late Sunday that could bring significant accumulating snow to the I-95 corridor from DC-to-Philly-to-NYC. A cold front will approach the region today and its passage will bring scattered showers and thunderstorms and high temperatures down some ten degrees between this afternoon and tomorrow afternoon. An even stronger cold front will push through later tomorrow and its passage will usher in noticeably colder Arctic air for the weekend as high pressure builds in to our north. By late in the weekend, strong low pressure is likely to form near the Mid-Atlantic coastline and it could actually generate accumulating snow in the I-95 corridor with several inches of wet snow on the table - stay tuned.
