   AREAS AFFECTED...MUCH OF OK

   CONCERNING...SEVERE THUNDERSTORM WATCH 492...

   VALID 160304Z - 160500Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 492
   CONTINUES.

   SUMMARY...A LINE OF THUNDERSTORMS WILL BE CAPABLE OF MARGINALLY
   SEVERE WIND AND HAIL...BUT AN ADDITIONAL WATCH IS NOT EXPECTED
   UNLESS INTENSITY INCREASES.

   DISCUSSION...AN MCS CONTINUES TO PROPAGATE IN A SWD DIRECTION OUT OF
   KANSAS AND NOW INTO NRN OK. THE ERN FRINGE IS BEING IMPEDED BY MORE
   STABLE AIR LOCATED TO THE E. MEANWHILE...OUTFLOW CONTINUES TO SURGE
   AHEAD OF THE SYSTEM BUT NEW CELLS WERE FORMING ALONG THE WRN FRINGE
   NEAR P28.

   WITH THE STRONGEST INSTABILITY GENERALLY ALONG AND W OF I-35...AND
   WITH CLOSER PROXIMITY TO WARMER INFLOW AIR WITH 10-15 KT SWLY 850 MB
   FLOW...THE BEST CHANCE OF SEVERE WIND OR HAIL APPEARS TO BE ACROSS
   NRN...CNTRL...AND WRN OK. AT THIS TIME...STORMS ARE NOT PARTICULARLY
   STRONG...BUT TRENDS WILL CONTINUED TO BE MONITORED FOR ANY POSSIBLE
   UPTICK IN INTENSITY. IF THIS WERE TO OCCUR...A NEW WATCH COULD BE
   REQUIRED.
