WRN U.S. TROUGH WILL DIG SEWD INTO THE CNTRL ROCKIES WEDNESDAY
BEFORE LEADING EDGE OF STRONGER FLOW ROTATES THROUGH SRN NM INTO THE
HIGH PLAINS. THIS FEATURE WILL AID SFC CYCLOGENESIS OVER THE NWRN
TX/OK PANHANDLE REGION BY LATE AFTERNOON WITH A WELL DEFINED COLD
FRONT EXPECTED TO BE DRAPED ACROSS SERN NEB...SWWD INTO SERN CO.
LARGE SCALE FORCING WILL FOCUS STRONGEST CONVECTIVE DEVELOPMENT
ALONG THE BOUNDARY ACROSS KS AS LOW LEVEL MOISTURE RETURN WILL BE
QUITE LIMITED. LATEST VIS SATELLITE IMAGERY AND OBSERVATIONAL DATA
SUGGEST AIRMASS MODIFICATION CONTINUES OVER THE GULF OF MEXICO. AS
A RESULT...ONLY A NARROW WEDGE OF MODEST MOISTURE RETURN WILL BE
NOTED ACROSS TX/OK INTO KS WHERE STRONG FORCING WILL BE REQUIRED FOR
THUNDERSTORM INITIATION. STRONG HEATING ACROSS THE TX PANHANDLE MAY
HOWEVER AID INITIATION SHORTLY AFTER 00Z ACROSS SWRN KS. ONCE THIS
ACTIVITY DEVELOPS...STRENGTHENING LLJ/WARM ADVECTION SHOULD DRIVE
THUNDERSTORM CLUSTERS ENEWD ACROSS KS TOWARD WRN MO. FORECAST
SOUNDINGS SUGGEST A FEW OF THE STRONGER UPDRAFTS MAY PRODUCE
MARGINALLY SEVERE HAIL.
