Why were the higher wind probs removed?  Anyone know?  Have the short range models backed off the instability/kinematics?

HRRR is beefing them up. The convection that is supposed to bring clouds is failing fast and the HRRR shows Central and EAstern NC getting a few hours of sun before the storms. HRRR actually has 2100+ cape south of Wake co.

 

12:30 update I think they will upgrade this area big time

This tornado warned storm is in an area where the SPC doesn't even have a tornado risk and surface temps are in the low to mid-50s. Dynamics of this system already flexing its muscles this morning.

 

I don't understand the specifics of it, but in these setups there are always surprising spin ups located along the cold-air wedge boundary. I suspect that is what's aiding this cell's rotation.

Good deal, thanks.  If we get any appreciable sunshine, we're going to be in trouble.

They upped tornado probs and lowered wind. They thought last night more of a line segment with less tornado threat now they're leaning more towards more individual cells thus less widespread wind damage but more tornadoes.

Also around 70 degrees down near the coast where the high temp was only supposed to be 72-74...
