Heights are still rising on the east coast at 84 hours..that movie probably has a poor ending to it.

From the H5 heights, I'd guess the low makes landfall on eastern LI. If it bombs enough, we'd stay mostly snow...also, the 540 line is well to our south early so we'd probably see a good front end dump even if we eventually mixed with sleet or rain. I just want to keep the beautiful snowpack intact, a little mixing doesn't hurt in that regard.

You should actually be the most excited for this threat because your location in NJ, west of NYC, is ideal for a solution that is close to a coastal hugger. Of course, if the GFS is closer to the actual verification, it's a moot point.

Maybe its remembering the Blizzard of 78, or being in Texas and not actually experiencing the snow, but wind effects are an important component for me, rain or snow.

Euro 10 meter winds showing 60 mph on Eastern Suffolk County 18Z Wednesday. OKX forecast skew-T BTW, tau 114, on the Op Euro is above freezing 700 mb on down, no question its rain. A little hard to eyeball, but OKX appears to have 60 knot winds below 900 mb on that forecast sounding. ECMWF free site shows 850 mb winds above 40 m/s, or about 80 knots at 120 hours.

Not directly related to the storm threat, but the ensembles show potential for another arctic outbreak at the end of the month about 10 days from now into the first couple days of February. They are building a monster PNA ridge out west that basically goes all the way up into the arctic ocean N of Alaska. Mallow might have to break out the shorts and hammock.

It has -16C 850s into New England and -12C down to DC for Feb 1st...thats pretty impressive on an ens mean 10-11 days out.

Will, for east coast snowstorms, what placement is best for the trof to go neg. tilt, over ga?

Yeah somewhere around there...in the SE US E of the Mississippi. Each storm is a little different though for the exact placement of where you'd want it to happen...depends on downstream blocking and such, but on average, its a favorable spot.
