LONG TERM /FRIDAY THROUGH MONDAY/...

By Friday, a deep trough will continue to move further east.
Confidence has continued to increase on the negative tilt nature of
this trough over the last few runs as it reaches the east coast. The
18/00z runs of the GEFS has backed off the center of low pressure
being closer to the coast whereas the EPS/NBM are trending a bit
more north-west. A more westward trend could bring a more widespread
significant snowfall for portions of the area. For now, there still
seems to be some discontinuity in the guidance as to the position of
the low which will greatly impacts the snow totals that are received
within the Mid-Atlantic region.

This system is not a slam dunk by any means with a lack of blocking
in the northern Atlantic. Nonetheless, the overall pattern for the
event seems to be honing in on a snowy solution for much of the area
with areas closer to the I-95 corridor having the higher totals for
now, given where the best forcing/moisture availability resides. Do
expect the Alleghenies to receive a fairly consistent snowfall for
the event due to upsloping. Given the uncertainties with this event,
have kept PoPs through Saturday evening but with a potentially fast
moving track on pace, we may see conditions begin to dramatically
improve during the day on Saturday. Other story will be the winds
with this system with a tight gradient between the strong Arctic
high pressure that will bring frigid cold temperatures Thursday and
as it departs and the upper trough begins to build into the area.
Coupled with these winds will be frigid cold temperatures,
especially Saturday night into Sunday. Wind chill values may become
more widespread in the negatives, even east of the Blue Ridge
Mountains. Wind Chill Watches/Warnings/Advisories may be needed.

Behind the system, high pressure will build back in and dominate for
the remainder of the weekend and into early next week. A slight
warming trend is possible beyond the system as well.

Today is probably our last day for major changes. Time is getting thin. I’m encouraged to see the 00z Euro, even SE VA and Delmarva get slammed. We are close but realistically, how much further west could this go? Even with a full phase?

I think its all about expectations.  Expecting a KU?  Best to step away from the thread.  Interesting in tracking a potential light to moderate event?  Absolutely in the game.

I’m expecting an FU so if that can be avoided it’s a win

06z Euro would have been a nice spot for the sub-forum. Solid snow probably I-95 on east with Advisory level stuff to the west, easy. @CAPE @Lowershoresadness @frd and anyone on the coast would have a great time if that run kept going. 

That would be a second time this winter for us easterners. I had 10.25" with the Jan 3rd system here in Crofton.

It's nice to see you south and east folks get a bit of a heater every once in a while. Doesn't happen often, but y'all can cash when things are right. I'm hoping we all are dancing with a couple inches of snow at least. Anymore to me is gravy. I'll be with my family and watching snow fall. Not much to hate there.

More snowy ‘cabin’ photos from CAPE, I’m in.

I had a heck of a time getting the cities to match up with the graphic. Thankfully the shift before last night got the key messages started. Notice how the probs went up, especially in New England. 

We also now see the storm in the day 4 WSO! Let's hope the probs keep going up for us!!
