   AREAS AFFECTED...EASTERN OK INTO FAR SOUTHEAST KS/SOUTHWEST MO AND
   WESTERN AR

   CONCERNING...TORNADO WATCH 199...

   VALID 240349Z - 240515Z

   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 199 CONTINUES.

   SUMMARY...A TORNADO/LOCALIZED WIND GUST THREAT WILL CONTINUE THROUGH
   LATE EVENING INTO THE OVERNIGHT...BUT THE OVERALL POTENTIAL SHOULD
   BECOME INCREASING MARGINAL/ISOLATED. TORNADO WATCH 199 CONTINUES
   UNTIL 09Z.

   DISCUSSION...THE EAST-NORTHEASTWARD MOVING SQUALL LINE ACROSS FAR
   NORTHEAST OK APPEARS TO HAVE BEGUN A DIMINISHING INTENSITY TREND
   OVER THE PAST HOUR...ALTHOUGH SOME STRONGER/POTENTIALLY SEVERE
   STORMS CONTINUE ON ITS LEADING EDGE AND ITS IMMEDIATE SOUTHEAST IN
   VICINITY OF A NORTHWEST-SOUTHEAST ORIENTED WARM FRONT AND RELATED
   SPATIALLY NARROW CORRIDOR OF MARITIME AIR ACROSS EASTERN OK AND
   WEST-CENTRAL/SOUTHWEST AR. A TORNADO/ISOLATED WIND DAMAGE POTENTIAL
   WILL CONTINUE ESPECIALLY ACROSS FAR NORTHEAST/EAST-CENTRAL OK
   THROUGH THE LATE EVENING HOURS. SOME SEVERE/TORNADO RISK COULD
   CONTINUE INTO NEARBY WESTERN AR AND/OR FAR SOUTHEAST KS/SOUTHWEST
   MO...BUT STORMS SHOULD EVENTUALLY OUTRUN THE MAIN
   INSTABILITY/LOW-LEVEL JET CORRIDOR...SUCH THAN AN ADDITIONAL WATCH
   ISSUANCE CURRENTLY SEEMS UNLIKELY.
