The continuous snow will be ending between 1-2 PM or so in the city.

This morning’s model runs had both the GFS and NAM nearly identical, with a QPF of 0.33 between 7 AM and 1 PM, then ending.

Snow totals in my area (just northwest of the city limits) has been 4 inches at 12:00 noon.  Still a bit to go.

Predicting snow totals is anything but easy.   The average between the NAM and GFS last night probably gave the best guess for the immediate PHL area.   The NBM model probably would have come up short on snow totals.
