EF4
Chase target:
Pratt, KS.
Timing:
Storm initiation 7 PM CDT.
Comments:
Storms will fire along a cold front during the early evening hours, and the southern-most storm in the line will be the target. Severe storms, capable of 1" hail and winds to 70mph, will be possible during the early evening.
Discussion:
In short, the best moisture will be located just to the east of the UA support. The right entrance region of a 40kt H5 streak will lift through SWRN KS while a 30kt H7 wave develops in response to the UA divergence. The target location is just to the W of the axis of maximum instability with MLCAPE's of 2500J/kg. Slow cyclogenesis will occur in the OK panhandle along the CF while the front stalls out in SRN KS. After dark, a 30kt LLJ should sustain storms into the late evening.
