It's already a mature s/w over the Midwest. It starts to dig SE and elongate as a shot of nrn stream energy digs in. SO you get a more elongated and large ULL vs a Jan 2011 nuke.
Some fronto too at H7. The ULL was a little east on this run. I would like to see it tick west...but something to watch. 3K NAM tries to get a little -SN tonight across ern areas.
