Range folding literally bisected the little "couplet", or at any rate, g2g shear region, on ENX.
Box wasn't range folded I don't think but you're right that the radar is pretty useless for what could be, theoretically speaking, some low level spinup.
As for me I've been in a holding pattern around storms in the DFW area for the last hour. Glad we had a lot of gas or we'd have diverted to Little Rock by now.
