That literally is the only way to express the model situation. If only we had a high-resolution NCEP model that is supposed to be favored in convective events. Oh wait....

 

SREF is usually pretty good in this range but not necessarily "killer" till morning of. I'd like to see it a little less progressive with the sfc low but it has arguably gotten 'better' since yesterday.

LWX likes low 90s for us this afternoon.... but says storm chances will be low till tonight due to lack of organized lift

 

I'm almost ready to bail on the first part.. tho I'd like the boundaries it might give us. Seems like only the NAM4K is showing much.

Earthlight was asked in the NYC forum where he thought the highest potential for tornadoes would be... his response:

 

 

In an area from near or just north of DCA through South/Southeast PA and into Southwest NJ. That threat may lift northward along the warm front into Central NJ as well.

Meh, the American models have been all over the place. Wait to see if the Euro holds..

 

it's sort of a discombobulated late phase/not really phase.. we always suck at phasing when we need it in winter. but the gfs sucks at modeling it too so who knows. tricky setup.. could easily bust.
