...there Is A Mdt Risk Of Svr Tstms Over Parts Of N Tx...ok And Wrn
Ar...
Combination Of Strengthening Deep Wind Field...increasing
Moisture/large Scale Ascent...and Daytime Heating Expected To Yield
An Environment Favorable For Sustained Supercells With Very Large
Hail...high Wind And Tornadoes Invof Sfc Wave And Associated Dry
Line And Warm/stationary Front Over Nw Tx And Wrn/srn Ok Thursday
Aftn.
It Remains Too Early To Comment Specifically On Mesoscale
Details...especially Given Likelihood For Elevated Warm Advection
Storms In Ok Early In The Day. But Overall Setup Should Result In A
Corridor Of Uncapped...very Unstable Air /sbcape Aoa 2500 J Per Kg/
Near Aforementioned Sfc Wave By Late Thursday Aftn. As The Wave
Develops Ese Toward The Red Rvr...expect At Least A Few Discrete
