CONCERNING...TORNADO WATCH 499...

VALID 100200Z - 100330Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 499 CONTINUES.

SUMMARY...PRIMARY THREATS APPEAR TO BE TRANSITIONING TO HEAVY
RAIN...DAMAGING WIND AND LARGE HAIL. HOWEVER...A COUPLE TORNADOES
REMAIN POSSIBLE NEXT FEW HOURS...MAINLY FROM NERN KS INTO NRN MO.

DISCUSSION...AS OF MID-EVENING NUMEROUS STORMS CONTINUE DEVELOPING
FROM NERN KS INTO EXTREME SERN NEB AND NRN MO WHERE BROADENING AND
INTENSIFYING LLJ IS INTERACTING WITH A CONVECTIVELY MODIFIED WARM
FRONT. 0-2 KM HODOGRAPH SIZE HAS INCREASED CONSIDERABLY IN
ASSOCIATION WITH THE LLJ...AND SUPERCELL STRUCTURES CONTINUE TO BE
OBSERVED...MAINLY OVER NRN MO. HOWEVER...TREND HAS BEEN FOR STORMS
TO MERGE INTO CLUSTERS AND LINE SEGMENTS WHICH /IN ADDITION TO THE
STABILIZING BOUNDARY LAYER/ APPEAR TO BE SERVING AS LIMITING FACTORS
FOR A MORE ROBUST TORNADO THREAT. NEVERTHELESS...GIVEN SIZE OF THE
LOW-LEVEL HODOGRAPHS AND A VERY MOIST BOUNDARY LAYER...A COUPLE OF
TORNADOES CANNOT BE RULED OUT AS STORMS DEVELOP EWD AND SEWD ALONG
THE BOUNDARY THIS EVENING.
