Regarding the light snow for PHL, today’s model runs have increased the QPF to about 0.15 inches of water for PHL and immediate adjacent areas. This is a small fraction of the QPF compared to last week’s storms.
When you’re dealing with such low QPF values, it’s hard to tell how much is model ‘noise’. (If you’re someone who wants more snow (?), the fact that it’s happening at night is in your favor.)
Whatever falls will result in slippery conditions Tuesday morning for the early commute.
