I was just admiring the forecast sounding for Ponca City, CAPE about 3000j/kg and 0-3km helicity about 500.
I think there could be major storm chaser convergence in southern Kansas/N Oklahoma.
I just looked at the temps in USA and its frigid there at the moment with single figure temps in Oklahoma/Kansas!! Its the middle of the night though. One reason why I think late season chasing is better, you tend to get warmer weather then.
DFW is a great spot for watching storms as you can jump on that inter terminal train and get good panoramas. lol
Today looks very messy in Oklahoma/Kansas.
I was suprised to see so much convection over N Texas today given the cap but it must have been very high based. I chased in the drought of 2006 and remember the high based storms well. Great for lightning
Lapse rates look to steepen during the day as an upper trough moves in with colder upper air. Convective chances will be linked to the amount of heating you can get but it won't need to get overly warm given upper level airmass will be quite cold.
