NWS STORM PREDICTION CENTER NORMAN OK
0628 PM CDT SAT AUG 13 2005

AREAS AFFECTED...ERN MO INTO CENTRAL/SRN IL AND WRN IND

CONCERNING...SEVERE THUNDERSTORM WATCH 719...

VALID 132328Z - 140030Z

DAMAGING WINDS REMAIN POSSIBLE ACROSS CENTRAL AND ERN PORTIONS OF WW
719.  SEVERE THREAT EAST OF WW 719 IS EXPECTED TO REMAIN
LOCALIZED...THUS PRECLUDING THE ISSUANCE OF A NEW WW AT THIS TIME.

23Z MESO-ANALYSIS SHOWED THE PRIMARY COLD FRONT EXTENDING FROM NRN
IND WSWWD ACROSS CENTRAL IL /TO THE NORTH OF THE EWD MOVING BOW
ECHOES/ AND INTO NRN MO.  A SECOND BOUNDARY EXTENDED FROM AN MCV
OVER NERN IND SWWD INTO THE APEX OF THE LEADING BOW ECHO OVER
CENTRAL IL...NEAR 25 NNW SLO.

RADAR TRENDS INDICATED A 30 KT FORWARD MOTION WITH THE LEADING BOW
ACROSS CENTRAL/SRN IL. A MODERATELY UNSTABLE AIR MASS IN ADVANCE OF
THIS LEADING BOW AND AN WELL DEVELOPED COLD POOL SUGGESTS A THREAT
FOR ISOLATED DAMAGING WINDS EWD MAINLY ALONG THE SECOND BOUNDARY
INTO IND.  THE SECOND BOW ECHO WAS MOVING EWD AT 40-45 KT ACROSS THE
STL METRO AREA.  WIDESPREAD WIND DAMAGE SHOULD BE LIMITED GIVEN THAT
THIS SECOND BOW IS LIKELY ELEVATED...SINCE IT IS MOVING INTO THE
STABLE COLD POOL REGION OF THE LEAD BOW.
