MESOSCALE DISCUSSION 1852
NWS STORM PREDICTION CENTER NORMAN OK
0826 PM CDT SUN JUL 24 2005

AREAS AFFECTED...NERN NEB...SERN SD...AND NRN/WRN IA

CONCERNING...SEVERE THUNDERSTORM WATCH 672...

VALID 250126Z - 250300Z

SEVERE STORMS EXPECTED TO CONTINUE THROUGH 03Z ACROSS PORTIONS OF WW
IN IA. ALTHOUGH THE THREAT APPEARS TO BE OVER FOR EXTREME SERN
SD...STORM DEVELOPMENT STILL POSSIBLE ACROSS NERN NEB...AND
A NEW WW IS POSSIBLE FOR PORTIONS OF AREA LATER TONIGHT.

A CLUSTER OF STORMS WERE LOCATED ACROSS THE ERN PORTION OF THE
WW...BASICALLY W AND N OF ALO. THESE STORMS SEEM TO HAVE DEVELOPED A
WEAK COLD POOL AND ARE PUSHING EWD. ONCE THESE STORMS MOVE EWD OUT
OF THE WW...ONLY A WEAKENING SUPERCELL WAS LOCATED ABOUT 85 WNW OF
DSM. ALTHOUGH THE AIR MASS WAS VERY UNSTABLE...WEAK LOW LEVEL
CONVERGENCE APPEARS TO BE THE MAIN FEATURE INHIBITING WIDESPREAD
COVERAGE...ESPECIALLY ACROSS NERN NEB. HOWEVER...LOW LEVEL JET IS
FORECAST TO STRENGTHEN THROUGH THE EVENING AND LIFT ALONG THE FRONT
MAY AID IN CONVECTIVE INITIATION LATER TONIGHT ACROSS PORTIONS OF
NERN NEB AND WRN IA. ALTHOUGH WIND FIELDS ARE NOT PARTICULARLY
STRONG... MLCAPES FROM 3000 TO 4000 J/KG AND VEERING WIND PROFILES
WOULD SUPPORT STORMS WITH WIND DAMAGE AND POSSIBLY HAIL.
