The NAM and GFS model’s 1 AM runs have come together with a QPF of about 0.15 inches water for Philadelphia, or about 2, maybe 3 inches of snow (due to a higher snow:water ratio).
For Philadelphia, the snow starts about daybreak or so and the models have light snow continuing through about 4PM. For 8 hours of snowfall, 2-3 inches total snowfall is very light.
It still looks like a much more significant snowfall for southeastern NJ.
While the current radar trends are consistent with last night’s models, this is still a lower than usual confidence forecast. Any late change in intensification could throw the snow totals off in either direction.
