MESOSCALE DISCUSSION 2043
NWS STORM PREDICTION CENTER NORMAN OK
0726 PM CDT WED AUG 18 2004

AREAS AFFECTED...SERN NEB / NERN KS / NRN MO / SRN IA / CENTRAL IL /
SRN IN

CONCERNING...SEVERE THUNDERSTORM WATCH 760...761...

VALID 190026Z - 190230Z

STRONG / SEVERE STORMS CONTINUE ACROSS PARTS OF WW 760 AND 761.  

LATEST RADAR IMAGERY SHOWS STORMS MOVING EWD / ESEWD ACROSS WW 760
AHEAD OF COLD FRONT...AND ESEWD ACROSS PARTS WW 761 IN REGION OF
LOW-LEVEL WARM ADVECTION.  INSTABILITY IS WEAKER ACROSS THE WRN HALF
OF WW 760...AND STORMS SHOULD DIURNALLY WEAKEN ACROSS THIS REGION.  


MEANWHILE...MORE UNSTABLE AIRMASS EXISTS FROM SERN IA / NERN MO SEWD
INTO SRN IN...WHERE STORMS HAVE BEGUN TO EVOLVE INTO A LARGE CLUSTER
OVER THE PAST HOUR OR SO.  AS LOW-LEVEL JET INCREASES FROM THE WSW
INTO THIS REGION...EXPECT BOTH PROPAGATIONAL COMPONENT AND
ORIENTATION OF INSTABILITY AXIS TO RESULT IN ESELY MCS MOTION ACROSS
WW 761.  ALTHOUGH AN ISOLATED TORNADO CANNOT BE RULED OUT...EXPECT
LOCALLY DAMAGING WINDS AND HAIL TO BE THE MAIN SEVERE THREATS.
