That may be the best chance. Really starting to lose confidence in the weak CCB.
Those squalls are nasty. Insane lapse rates, and plenty of dry air at 900mb. Perfect ingredients for the squalls making their own cold air. GFS showing 500 SBCAPE with temps in the 30s to low 40s.
All models have trended further east and less amplified with the northern stream. That is what it causing the later phase. This was similar to 2010 when models miraculously brought the storm back .
Not the likely scenario, but still worth watching 18z and 00z in case somehow the NS trends back west again.
GFS trended northwest with the track and saucier with the jackpot. It's within a run or two of matching the euro and it's 700mb frontogenisis max matches well with where the Euro had the jackpot. NE PA to NW ME.
If the deathband formed there, it would match the Euro.
18z ICON is my favorite run by far because it turns the elongated frontal wave into a bowling ball the fastest and deforms the crap out of NH and the berks. Best chance for someone to get a foot.
ICON and RGEM also really amped up. I think this will be like every other thing I thought was worth watching this year, it will burn my eyes, and the GFS will prove itself a joke.
CMC rides the low up the front much quicker, hence it's further north with the track. Looks like north of Albany to Portland gets some snow. Unusal for May, but a lot less insane than the GFS.
Models have been all over the place with this system the past 36hrs, so I'd think there's well above average uncertainty on the track and intensity of that low for 5 days out.
Looks like models abandon the idea of crushing the southern stream with the PV day 4-5. I thought I was losing my mind there for a while..
Now looks like a phase,. Rain and wind, with some pretty insane windchills for May.
