   CONCERNING...TORNADO WATCH 124...
   
   VALID 110152Z - 110245Z
   
   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 124 CONTINUES.
   
   CONVECTION IS RAPIDLY DEVELOPING ACROSS THE WW AREA...WITH INITIALLY
   DISCRETE AND SMALL CLUSTERS OF STORMS CAPABLE OF PRODUCING LARGE
   HAIL...DMGG WINDS...AND TORNADOES.
   
   THUNDERSTORMS APPEAR TO BE RAPIDLY DEVELOPING IN RESPONSE TO A
   COMPLEX SERIES OF UPPER WAVES AND ASSOCIATED SURFACE BOUNDARIES.
   INITIAL STORMS LIKELY DEVELOPED ALONG THE SRN EDGE OF IMPLIED LIFT
   OBSERVED ON WV IMAGERY OVER SWRN MO/ERN OK/N CNTRL TX...AND AS THE
   LEADING EDGE OF ADDITIONAL UPPER ASCENT /NOW OVER CNTRL OK SWWD
   THROUGH FAR WRN TX/ APPROACHES FROM THE WEST. STRENGTHENING LOW
   LEVEL WARM ADVECTION IN ASSOCIATION WITH THE NOCTURNAL LOW LEVEL JET
   HAS INFLUENCED TWO SEPARATE LINES OF CONVECTIVE DEVELOPMENT...ALONG
   A DRYLINE CIRCULATION...AND ALONG A WEAK COLD FRONT THAT IS QUICKLY
   OVERTAKING THE DRYLINE. A STRONGER COLD FRONT REMAINS TO THE
   NORTH...OVER NRN MO SWWD THROUGH SERN KS/WRN OK...AND WILL SUPPORT
   ADDITIONAL DEVELOPMENT AS THE THREE IMPLIED BOUNDARIES CONVERGE.
   SHEAR PROFILES AS NOTED ON THE SPRINGFIELD VAD WIND PROFILE
   CHARACTERIZED BY AROUND 350 M2S2 SRH FROM 0-3 KM...AND INFLUX OF
   WARM/MOIST AIR IN THE WARM SECTOR MAY SUPPORT TORNADIC
   DEVELOPMENT...ESPECIALLY IN INITIALLY DISCRETE STORMS. STRONG
   FORCING AND SHEAR VECTORS PRIMARILY ORIENTED PARALLEL TO THE
   NUMEROUS BOUNDARIES SHOULD QUICKLY LEAD TO A BROKEN LINE OF
   CONVECTION AND INCREASING COVERAGE OF STORMS.
