Big takeaway from the 12z GEFS is that only 2 members show a miss, and about 7 show mostly rain. Just about every other run is a nice hit from I-95 NW. Even Baltimore City and DCA get accumulating snow. A good shift overal. Hope the UKMET and Euro agree.
Yup. We're getting into the Euro's wheelhouse. If it trends towards the GFS through Sunday, then man we might have some hope. FWIW, doesn't look like the GFS is warm through Christmas so this snow might stick around for a bit.
12z OPS GFS kills the primary low in Tennessee this round. By HR120 the coastal low is popping off Hatteras. Also has a 1034mb high in Quebec instead of Newfoundland. This is a good shift. Hope the GEFS moves this way too. Onto the 12z Euro.
To my eye, the 12z GFS OP is a good run for everyone N&W of I-95 for the 12/16 storm. Legit advisory criteria immediate I-95 and possible warning event for the the usual jackpot spots.
00z / 06z Euro OP/ENS loving the I-81 corridor next week. Even down into THV/LNS get some love. Get your snow shovels ready and put those Christmas lights out!
@usedtobe did a lot of research with this. Big storms occur during the NAO changing toward a negative state or trending away. Essentially, you need a big event to flip the antecedent state of the oscillation.
Fun fact with this event...the Ohio primary ended up stronger than progged, BUT the transfer to the coastal was pretty quick. A rare instance where up north into the PA mason/dixon counties boomed and DC didn't switch to rain. This was a rare wind for eveyone.
