   CONCERNING...SEVERE THUNDERSTORM WATCH 294...
   
   VALID 130309Z - 130415Z
   
   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 294
   CONTINUES.
   
   SEVERE TSTM WATCH 294 CONTINUES UNTIL 06Z...WITH CONTINUED POTENTIAL
   FOR DAMAGING WINDS AND SOME SEVERE HAIL MAINLY ACROSS
   SOUTH-CENTRAL/SOUTHEAST MO INTO FAR NORTHEAST AR.
   
   A COMPLEX OF TSTMS CONTINUES TO PROGRESS EASTWARD PRIMARILY
   ALONG/SOUTH OF I-44 IN SOUTH-CENTRAL MO...WITH A COLD
   POOL/BUBBLE-HIGH EVIDENT IN RADAR IMAGERY/SURFACE OBSERVATIONS
   ACROSS SOUTHWEST MO. WHILE TOTAL BUOYANCY IS WEAKER INTO
   EAST-CENTRAL/SOUTHEAST MO...THE EXISTING COLD POOL/PROPAGATION OF
   THE CONVECTIVE COMPLEX INTO A RESIDUALLY WARM BOUNDARY LAYER ACROSS
   EASTERN MO /WITH RELATIVELY DRY AIR ALOFT AND STEEP LAPSE RATES PER
   RUC SOUNDINGS/ WILL CONTINUE TO SUPPORT THE POSSIBILITY OF
   STRONG/DAMAGING DOWNDRAFTS IN ADDITION TO AN EPISODIC HAIL THREAT
   OVER THE NEXT COUPLE OF HOURS. WITH EXPECTATIONS FOR THE SEVERE
   THREAT TO GRADUALLY WANE TOWARD MIDNIGHT LOCAL TIME...AN ADDITIONAL
   WATCH ISSUANCE IS NOT CURRENTLY EXPECTED...ALTHOUGH LOCAL WFO
   EXTENSIONS MAY BE WARRANTED AND TRENDS WILL OTHERWISE CONTINUE TO BE
   MONITORED.
