CONCERNING...TORNADO WATCH 134...
VALID 142318Z - 150115Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 134 CONTINUES.
SEVERE/ISOLATED TORNADO THREAT CONTINUES ACROSS PORTIONS OF THE ERN
HALF OF KS AND ADJACENT AREAS.
ARCING LINE OF STRONG/SEVERE STORMS -- INCLUDING EMBEDDED ROTATING
CELLS -- CONTINUES FROM N CENTRAL KS AND FAR S CENTRAL NEB ESEWD
ACROSS ERN KS...ALONG AND JUST AHEAD OF A DRYLINE/COLD FRONT.
A RIBBON OF MORE MOIST/UNSTABLE BOUNDARY LAYER AIR REMAINS EVIDENT
AHEAD OF THE FRONT/DRYLINE -- COINCIDENT WITH THE LINE OF
CONVECTION...WITH A MUCH MORE STABLE/CAPPED AIRMASS REMAINING IN
PLACE ACROSS FAR ERN KS AND INTO WRN MO. THUS...EXPECT ANY SEVERE
POTENTIAL TO BE SLOW TO SHIFT EWD -- WITH THE OVERALL THREAT LIKELY
TO DIMINISH AS THIS OCCURS. NONETHELESS...AMPLE THREAT MAY SLOWLY
SPILL JUST EAST WW 134 TO REQUIRE AN ADDITIONAL/NARROW WATCH
ISSUANCE AFTER 15/00Z.
UNTIL THEN...SUFFICIENT INSTABILITY AND FAVORABLE DEEP-LAYER WIND
FIELD WILL MAINTAIN SEVERE THREAT -- INCLUDING THE POTENTIAL FOR
ISOLATED/BRIEF TORNADOES -- WITH THE BAND OF ONGOING STORMS.
