MESOSCALE DISCUSSION 1495
NWS STORM PREDICTION CENTER NORMAN OK
0946 PM CDT TUE JUL 23 2013
AREAS AFFECTED...A LARGE PART OF AR...SRN MO...FAR SERN KS
CONCERNING...SEVERE THUNDERSTORM WATCH 437...
VALID 240246Z - 240345Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 437
CONTINUES.
SUMMARY...A LARGE PART OF SVR TSTM WATCH 437 WILL BE ALLOWED TO
EXPIRE ON SCHEDULE AT 03Z...THOUGH THE SVR THREAT COULD PERSIST
ACROSS PARTS OF SWRN MO AND FAR SERN KS AFTER 03Z PERHAPS WARRANTING
A LOCAL EXTENSION IN TIME.
DISCUSSION...ACROSS MOST PORTIONS OF WW 437...WIDESPREAD CONVECTIVE
OVERTURNING HAS LARGELY DIMINISHED THE SVR THREAT IN THE NEAR TERM
AND THE WW MAY BE ALLOWED TO EXPIRE ON SCHEDULE AT 03Z. HOWEVER...A
WWD-MOVING OUTFLOW BOUNDARY ACROSS SWRN MO AND FAR NWRN AR MAY
CONTINUE TO BE THE FOCUS FOR NEW CONVECTIVE DEVELOPMENT DURING THE
NEXT FEW HOURS. THE 00Z SGF RAOB SAMPLES AN ENVIRONMENT WITH STRONG
BUOYANCY AND MODERATE MID-LEVEL FLOW WHICH COULD YIELD SOME SVR
THREAT PERSISTING BEYOND 03Z IN SWRN MO...FAR SERN KS...AND FAR NWRN
AR. ALSO...INTENSE CONVECTION UPSTREAM ACROSS KS MAY MOVE ACROSS
PARTS OF THE REGION LATER TONIGHT...AND THIS ACTIVITY WILL BE
MONITORED FOR ADDITIONAL WW ISSUANCE LATER TONIGHT.
