Snowfall map

Parts of Delaware, South Jersey, could see 5 inches.

Snowfall map

As our online story notes, the accumulation profile of tonight's storm will be the reverse of this morning's, with higher amounts to the south.

The National Weather Service snow map has a 5-inch zone just south of Wilmington and extending across South Jersey.

The weather service notes that the storm is a quick mover but has good, efficient snow dynamics with solid snow-growth potential and strong upper-level jet winds to give the storm a kick.

Temperatures have been dropping, and at 5 they were in the 30s just about everywhere from Dover on north.

Some light rain was falling along the Maryland eastern Shore, but that's due to go over to snow later and accumulate 3 or 4 inches.

One thing worth noting is the sharp northern cut-off that shows up on the snow map. Taken literally, Philadelphia International Airport would get twice as much as the far Northeast.

You'll note on the map that National Park, the "Philadelphia" official measuring site, is in the "4.0" zone. If that verified to the decimal point (don't worry, it won't), that would up the seasonal snow total from the current 38.0, to 42.0.

That would place this season all alone in 10th place on the all-time list, a might 0.2 inches ahead of 1957-58. That season's total was boosted by the 11.4 inches measured in the infamous equinox storm of March 19-21.

Here is the reigning Top 10 list:

  1.        78.7              2009-10
  2.        65.5              1995-6
  3.        55.4              1898-9
  4.        54.9              1977-8
  5.        49.1              1960-1
  6.        46.3              2002-3
  7.        44.3              1966-7
  8.        43.9              1917-8
  9.        43.8              1904-5
  10.      41.8              1957-8
