NWS STORM PREDICTION CENTER NORMAN OK
0206 PM CDT WED MAR 28 2012
AREAS AFFECTED...EXTREME SCNTRL NEB...NERN KS
CONCERNING...SEVERE POTENTIAL...WATCH LIKELY
VALID 281906Z - 282030Z
CONVECTION WILL GRADUALLY INCREASE ALONG THE NEB/KS BORDER OVER THE
NEXT FEW HOURS. SEVERE THUNDERSTORMS ARE EXPECTED AND A WATCH WILL
LIKELY BE ISSUED BY 20-21Z.
LATEST VIS IMAGERY CLEARLY DEPICTS AN EXPANDING CU FIELD WITHIN THE
BOUNDARY LAYER ACROSS MUCH OF NRN KS. THIS EXPANSION IS OCCURRING
COINCIDENT WITH AFTERNOON HEATING ALONG A WELL DEFINED SFC BOUNDARY
THAT IS DRAPED FROM JUST SOUTH OF THE MKC METRO AREA...NWWD TO NEAR
SLN. LATEST INDICATIONS ARE THAT ELEVATED TSTMS OVER SRN NEB WILL
GRADUALLY EXPAND AND DEVELOP SEWD INTO NCNTRL KS AND BECOME ROOTED
IN HIGHER THETA-E AIRMASS OVER NERN KS. VERTICAL SHEAR PROFILES
CERTAINLY SUPPORT ORGANIZED ROTATING UPDRAFTS BUT STORM MOTIONS WILL
BE SLOW AND STORM MERGERS AND PROPAGATION SHOULD ENCOURAGE
DEVELOPMENT TOWARD THE METRO MKC AREA LATER THIS EVENING. LARGE
HAIL IS THE GREATEST SEVERE RISK WITH THIS ACTIVITY...THOUGH EARLY
SUPERCELL STORM MODES COULD RESULT IN AN ISOLATED TORNADO.
