That kink in the isobars starting from ~ORH that can be see through Virginia is a signature of significant cold air damming for the mid Atlantic region.
Guys gotta pull out the classic cold Damming setups to see how this will play out. The apps really enhance the push and depth of the cold; it will never get resolved by guidance.
At a minimum expect the surface freezing line to remain ~25 miles further south/east than progged. That’s your easy bet.
The big surprise will be the -NAO look that this thing develops late tomorrow morning as it moves inside the benchmark, slowing down and throwing CCB back from north central Jersey to throughout New England.
We will all be waking up to a storm in its 6th/7th inning.
NYC metro has biggest upside potential.
The surface high position/intensity and antecedent is pretty well perfect. It’s one of the rare times to bet against the “warming 925 - 800 into go time”
I’ve been saying a NYC and Boston jackpots.
both have meso enhancements from a stationary coastal front and no mixing… In the case of NYC, it’s on the line of current guidance but I think it sticks with 90%+ snow.
That’s a solid endorsement now by the GEFS.
I could easily see this evolving to include a NYC metro jackpot.
Makes sense. So overdue.
And with how cold this winter has been it’s the year shit can’t break wrong last minute. You can stack it even more considering the calendar and peak climo.
That’s a good baseline right here.
right now I’m thinking BOS is like 24-30” and I’m 12-18”
That’s a low confidence game though at this stage, but gun to head guess right now, that’s how I’d roll
Really good look with this storm at this hour and latest trends.
I also don’t think the qpf amounts are done moving higher.
Watching for a slowing trend…
