Your welcome Doug.

Helicity is just about as bad as what I was seeing forecast in AL and SE TN for the 4/27 outbreak.

Only a slight difference in that winds from the surface thru the boundary layer maybe 10 to 15 knots less this time.  

However, once above 700mb, they accelerate to 80 to 100 knots with a huge twist.

EF4 / EF5 stuff.

Lapse rate is in fact even more extreme this time.

That along with a cloud cover this morning, is going to make the cap break extremely explosive this afternoon.

Maybe another Joplin scenario.

If I were in Oklahoma City, I would be buggin.
