Storm Threat Dec 26-28 Period


Ralph Wiggum

Recommended Posts

Off Wunderground maps, people north of a UKT-RDG-MDT line stay snow through at least hour 99. Probably 3-6" up there with 6"+ in the Pocs.

Even the immediate Philly burbs (essentially northwest of US 1) sees around an inch before changeover. Possibly 2-3" DYL-PTW.

So now we're intrigued again, haha.

Didn't we go through this 2 years ago with a storm that kept trending toward the fishes until being brought back west at the "last minute"? Could there be a little Christmas magic again this year, but only in reverse and the storm trends back east? Perhaps the Euro is on to something... :unsure:

The problem right now is most of us here in this region are going to need so much help to get this into a wintry threat I don't think we can get it. For the all the folks near the coast or in Philly/S NJ we need that coastal transfer to occur early enough to get the low off the Delmarva or ACY to bomb out and give us a chance for snow behind the storm. If the transfer occurs too far west and the low tracks more into the CT river valley or Hudson Valley we downslope and don't get anything behind it.

With the east shift in the Euro and the ukie staying offshore interior areas still have a good shot. GFS is now on the on the west side of guidance.

UK verbatim ends up as rain south/east of 222. Whether it snows front end or not you can't tell based on the maps I have but it does warm the below 850 up above freezing.

If, by interior, you're talking Central PA and Poconos above I-80, I can agree with this a bit.

That said, it doesn't look *good* as of now for Philly.

Agree it doesn't look good for philly. Philly always needed everything to break right with warm ocean 50 miles away. Interior sections have more wiggle room. As usual need to be 1-2 days out to pin down details.

Question. Are we still talking about ice in Philly? Or is it too warm for that as well.? I noticed dtn took out all the snow on their forecast this morning. Looks like a good 1.5 inch rain storm.

Unlikely in Philly. More likely in LV+SV with Euro track and if cold air damming is strong.

given trend, not getting hopes up on one Euro hiccup.

I can't see it as well from home but the dp/dt on the euro night runs only look pretty similar. Regardless south and east of the fall line the antecedent conditions are not that promising (unless the Christmas Eve low verifies more robust) and while having the nao trend positive is what one would want to have it turn the corner, if the initial low forms that far west, a steadier state nao looks like would have done a better trick. Have a Merry Christmas. No ice please.
