12:30 PM | Snow not quite done with yet; especially, across portions of New Jersey

Discussion
While the snow has lightened up in some parts of the Mid-Atlantic, this “March Madness” snow is not quite over with yet. In fact, the coastal low is intensifying rapidly and snow has resumed in the DC metro region after having stopped during the mid-morning hours. An expansion of the radar loop in the DC region is tied in with the upper level dynamics just now entering the picture in the Mid-Atlantic region. Snow is likely to continue into the evening hours at varying intensities throughout much of the Mid-Atlantic region between DC and NYC. The snow will also mix with rain at times; especially, when it lightens up, and the roads will simply be wet during the afternoon hours. However, slick conditions could return overnight on untreated road surfaces as temperatures will drop to slightly below freezing. The highest snowfall amounts may end up in the interior sections of central and southern New Jersey with 6+ inches possible in spots as the coastal low starts to really crank and generates heavy banding near the coast later today. Snow has already reached 3+ inches in many suburban Philly locations (e.g. 4.5 Glenmore, PA, 4.5 East Nantmeal, PA, 3.8 Royersford, PA, 3.2 Wayne, PA, 3.2 Gilbertsville, PA, 3.0 Exton, PA) and while more small accumulations are possible, there will be some melting as well given the high sun angle this time of year.
Elsewhere, the immediate DC and Baltimore metro regions have already received 1-3 inches of snow with 3-6 inches in some of their northern and western suburbs (e.g. 3.8 Chantilly, VA, 4.0 Leesburg, VA, 3.2 Lorton, VA, 3.5 Chevy Chase, MD, 5.0 Parksville, MD, 5.4 Columbia, MD). Reagan National Airport (DC) has actually already recorded their highest snowfall amount since January 2011 with an inch and a half; BWI was at 2.1 inches as of late morning. Philly Airport needs to exceed 2.3 inches to make this their biggest snowfall in two years. The snow will increase in intensity in the NYC metro during the late afternoon and early evening hours, but those areas north of Long Island, NY will likely not receive any significant precipitation from this storm.
Finally, Opening Day is only a week away.
