I’m no Randy but through hr36 the gfs will probably NOT end up a disaster.

Pretty similar through hr 65

Looks like the stripe got more narrow

It will end up falling on 1 lane of 95 from DC to NY

Yeah virtually identical - awful for nw areas.

This will not be the event that unites us unfortunately. Good thing is it is a rather wimpy pos so even those who get the 'good' snow are probably looking at a max of 2-3", and most will see an inch or less.

Really looked like it might come north a touch even if still narrow but the GFS is dead set on a bay jackpot

Doesn’t look like the most will involve you.

Or you on most guidance.

The latest blend should relax some of those on the fringe on various model simulations. This appears to be a relatively small scale event, but still enough variation among the models, so we just cant know yet. Read enough AFDs and one will find the forecast offices prefer to go with the NBM at this range in these situations.

[WEATHER53]

So we had a good projection but the problem is in 6 hours the examples will be very different.  Won’t build on this run, won’t increase, and will revert back to 0-2.  Thus , come verification time (if this is even employed anymore) the range of 0-4” will be confirmed

The 1934Z GRAF seems to support the model consensus

D***That's some h********, and how it just breaks up with the mountains

[CAPE]

Mount Holly going with a general 1-3", and defaulting to the NBM(surprise!) due to the current disparity among the guidance. Also mention the potential for a stripe of 3-5" somewhere in the area if some of the more juiced up runs verify.

[H2O]

Looks like a bunch of y’all are in live and die mode for every model run. Gets fcking tedious. 
 

Whatever falls falls.
