Final Snow Totals can be found at http://forecast.weather.gov/product.php?site=NWS&issuedby=PHI&product=PNS&format=CI&version=1&glossary=0

The latest NAM data is in and it shows the precipitation taping off and ending between 12 and 2 PM in PHL and its immediate suburbs, with just lingering snow showers possible from wrap-around moisture.  Winds will pick up.

Surface temperatures are predicted to drop by 2 PM, as well as temperatures in the upper atmosphere.

A changeover to a bit of snow or snow/sleet mix is possible before ending. BUT the thermal profiles still favor a precipitation mix of sleet/rain/snow and upper atmosphere temperatures remain a bit  too warm for much snow formation before the precip exits.

Final snowfall/sleet totals won’t be much different than what you see out your window right now.    What you see is what you’ll get.
