The peak snow season in Philadelphia is about two months away, but big snows have occurred in late November.
On this date way back in 1898, officially 6 inches of snow fell in Philadelphia, with an additional 3-plus inches the following day.
The storm total -- 9.2 inches -- remains a November record.

Hard to think about snow when its raining and 60 degrees out -- how about some weather stats on the warmest Novembers and Decembers on record Tony?
Or what about that fog today -- what was the heaviest recorded fog we have experienced in the city?

Don't get goodies like that very often!
Wx in the mid-Atlantic had been mild up until the arctic frontal passage on the 23rd after which HIGH pressure flooded the eastern half of the country chopping AM dew points @ PHL from 44° to 14° setting the stage for the heavy snow a few days later.
Surface maps preceding the record-setting event suggest a ridge-W / trof-E +PNA-type upper air pattern had developed. On the 25th...LOW pressure in the northern stream moved into the Great Lakes from western Canada then transferred its energy to a Miller 'B' storm off the NJ coast on the evening of the 26th.
PHL posted 0.92" storm-total liquid...for a SN:H2O of 10:1. ACY carried 1.24"...most of which probably fell as rain given the day/s max temperature was 40°...altho the 11/27 surface chart indicates snow was falling at 8 AM. OTOH...PHL/s max 'storm day' temp was 32°.
The late fall storm continued up the coast dumping ~9" on BOS and ~17" on PWM on the 27th and 28th.
The pre-season excitement didn/t last long. The upper air pattern appears to have relaxed a few days later. The storm track reverted to its pre-snow storm position through the OH River Valley and post-frontal air masses from the PAC returned to the east.
