USA - Moderate Risk - NE/KS & OK/AR/MO/TN - 28-29th Feb 12
Posted 28 February 2012 - 11:55
A particularly strong mid level jet with risks for the TP over the NE/KS border and a very dynamic threat for OK/AR north-eastwards. Was considering AR up until last night from a virtual chase perspective, but it would be going into the dark and looks to become a nasty line-out, so would probably plump for the earlier stuff over Nrn KS into NE.
Mid-level jet above 90kts looks really potent late in the period, instability better further south but appears conditional on prior cloud cover? Could get quite nasty for Dixie Alley overnight.

I am just watching a couple of the video feeds from severe studios and also the Omaha Twister chasers at tornadovideos.net - some nice cloud vistas!
