LOL,no, I got screwed in Newark, DE where we were perhaps 25 mi from a non-moving deformation band. Snowed lightly all day and we got a whopping 3", perhaps less. This storm might also have an unforgiving gradient rapidly getting worse to the S&W of PHL.

Us in Delco might do well. But in S/W chester county into MD might see massive drop-offs in amounts even into New Castle DE.

Any indication that this is the farthest west this will trend, or could this thing still be modeled slightly further east? Us weenies along the Northeast extension want some love, and we are missing out by like 30 miles!

It did trend west, but also got stronger which tightened up the gradient. I don't think any amount of westward movement can save us at this point. It is what it is.

Not bad at all really.......we (eastern PA) were never going to see 10+" from this event, maybe with 12-15:1 ratios and a few intense bands some sports will end up with 8 or 9 inches.

It ain't over until the bovine sings. The NAM calls for a 26mb bombing in less than 15 hours. That's a lot. If it were to maintain its current track and be a little weaker, you and I would be in the game for a higher amount. I think!

Latest Wxsim continues to be steady with .50" of precip....with higher ratios still see a 5 to 7" event in the NW Philly burbs. I expect the GFS will come in a tad wetter than 18z and we will be getting closer to consensus. Well that is until we begin the radar hallucinations (or in a Miller B) and the where the heck is the backfill on the radar comments....

Should be an interesting evening tomorrow. I have a very strong suspicion there will be some surprises.
