I took a quick look at the thermal profiles from this morning’s model run…   A bit warm in the atmosphere around daybreak, (rain mixes in) before the storm begins to deepen.   This will reduce accumulations in Philadelphia area by several inches.   8 inches looking like a good guess, still the higher amounts, 12+  north and west of the city.

We’ll need to wait until this evening for the real final totals- about 9:45 PM
