VALID 232014Z - 232215Z

...SEVERE THUNDERSTORM WATCH WILL BE REQUIRED FOR PORTIONS OF THE
HIGH PLAINS OF KS...OK/TX PANHANDLE...

BOUNDARY LAYER HAS WARMED RAPIDLY ACROSS THE CNTRL/SRN HIGH
PLAINS...ESPECIALLY POST DRYLINE WHERE LOWEST 3KM LAPSE RATES ARE
NEAR DRY ADIABATIC.  IT APPEARS DRYLINE HAS MIXED AS FAR EAST AS IT
WILL GO THIS AFTERNOON...WITH AN APPARENT NWWD MOISTURE SURGE NOW
ADVECTING INTO THE ERN TX PANHANDLE AS PRESSURE FALLS FOCUS IN THE
LEE OF THE SRN CO ROCKIES.  STEEP LAPSE RATE ENVIRONMENT HAS AIDED
HIGH BASED CONVECTION WITH ISOLATED LIGHTNING OVER SERN CO/SWRN
KS...WHICH IS SPREADING NEWD AT ROUGHLY 40KT.  THIS SPEED WOULD
ALLOW DEEP CONVECTION/BOUNDARY LAYER MOISTURE INTERSECTION BY 21Z.

ACROSS THE TX PANHANDLE.  IT APPEARS SIGNIFICANT THUNDERSTORM
DEVELOPMENT WILL OCCUR ACROSS THIS REGION OVER THE NEXT FEW HOURS
