STRONG CONVECTION...POSSIBLY SEVERE...IS EXPECTED TO DEVELOP ALONG
TRAILING SFC FRONT OVER THE SRN HIGH PLAINS THURSDAY. LATEST MODEL
GUIDANCE STRONGLY IMPLY THAT UPSLOPE FLOW ALONG WITH STRONG DIURNAL
HEATING WILL REMOVE THE CAP ACROSS THE TX/OK PANHANDLES INTO SERN
CO. FORECAST SHEAR ACROSS THIS REGION IS SUPPORTIVE OF DEEP ROTATING
UPDRAFTS AS SELY LOW LEVEL FLOW VEERS INTO THE WNW AT MID LEVELS.
ADDITIONALLY...LATEST WV IMAGERY SUGGESTS A WELL DEFINED SHORTWAVE
TROUGH EJECTING ACROSS SRN CA WILL SPREAD INTO THE HIGH PLAINS
AROUND PEAK HEATING. THIS SHOULD ENHANCE THE CONVECTIVE POTENTIAL
WITH EARLY SUPERCELLS EVOLVING INTO SEVERAL THUNDERSTORM CLUSTERS BY
EVENING. LARGE HAIL - DAMAGING WINDS AND PERHAPS AN ISOLATED
TORNADO ARE THE SEVERE THREATS WITH THIS ACTIVITY.
