    Thursday's snowstorm is now expected to be a two, possibly even a 3-day event.

    The rain/snow mix across the area Thursday morning will turn into heavier snowfall at Thursday afternoon as the air gets colder and more moisture moves in. Snow and sustained winds are expected to last through Friday morning.

    Philadelphia public and parochial schools are closed and the city is in Snow Emergency mode.

    We Could See a Foot of Snow in Philly

    [PHI] We Could See a Foot of Snow in Philly
    NBC10 Meteorologist Bill Henley's forecast at 7 a.m. on Thursday, Feb. 25, 2010 calls for two or three-day snow event and possibly a foot of snow in the city when it's over.

    The morning commute wasn't much of a problem aside from a few slippery roads, but the afternoon commute could be treacherous.

    This storm could bring up to a foot of snow to the city by the time it's over and because the snow will be wet and heavy, we could see toppled trees and snapped power lines.

    "The storm track should be a very unusual one," Schwartz said. " It is developing off the North Carolina coast and should move to the northeast toward Cape Cod."

    Here's a timeline of when the storm will intensify:

    5 a.m. - 10 a.m. Thurs.Slushy Accumulations
    10 a.m. - 5 p.m. Thurs.Snow/Wind Increase
    5 p.m. Thurs. - Midnight Friday

    Heaviest Snow/Wind

    Overnight Friday

    Heavy Snow/Wind

    Friday Morning

    Snow Becomes Lighter

    Here are the estimated snow totals as of early Thursday morning:

    Central and Southern Delaware3 to 6 inches
    South Jersey, Wilmington, Del. and some Pa. suburbs6 to 10 inches
    Philadelphia and its suburbs, Central Jersey and Allentown10 to 15 inches
    Lehigh Valley, Trenton and the Poconos15 to 20 inches

    Here's a map:

    By late Thursday morning, the wet snow should start slushing up untreated roads and sidewalks. That'll lay the groundwork for the next phase -- accumulation, Glenn says.

    Winds will also be a major factor in this storm. They're expected to increase from 10 m.p.h. in the morning to 40 m.p.h. by night with a possibility of gusts clocking 60 m.p.h.

    Those winds, coupled with the heavy snow and slushy base equates to a possible Category 5 - Crippling storm for our area for the fourth time this winter.

    Officials say they have over 400 staffers ready to hit the roads when the conditions reach critical mass.
