CONCERNING...TORNADO WATCH 249...

VALID 112213Z - 112345Z

THROUGH 23Z-00Z...GREATEST TORNADO THREAT WILL PERSIST ACROSS NRN
PORTIONS OF WW AREA.

AS OF 2200Z...GLD VOLUMETRIC RADAR DATA SHOW 3 WELL-DEFINED
SUPERCELLS...35 SW OF IML...45 NW GLD...AND 35 NW OF GLD MOVING

SUGGESTS THAT THESE STORMS ARE DEVELOPING AT INTERSECTION OF
HORIZONTAL CONVECTIVE ROLLS WITH DRYLINE WITHIN MODERATELY UNSTABLE
ENVIRONMENT. CURRENT GLD VWP INDICATES THAT LOW-LEVEL SHEAR WITHIN
AMBIENT ENVIRONMENT IS RELATIVELY STRONG WITH 0-1 KM SRH OF 150-200
M2/S2. MOREOVER...A SUBTLE BOUNDARY /POSSIBLY WARM FRONT/ CURRENTLY
EXISTS FROM 45 ESE OF AKO TO NEWD TO NEAR MCK WITH LIKELY STRONGER
LOW-LEVEL SHEAR ALONG AND N OF THIS FEATURE.

THROUGH 23-00Z...IT APPEARS GREATEST TORNADO POTENTIAL WILL BE WITH
AFOREMENTIONED SUPERCELLS AS THEY MOVE NEWD AND INTERACT WITH THIS
BOUNDARY.
