MESOSCALE DISCUSSION 1452
NWS STORM PREDICTION CENTER NORMAN OK
0842 PM CDT FRI JUN 24 2005

AREAS AFFECTED...ERN NEB/FAR SERN SD/MUCH OF IA/SWRN WI

CONCERNING...SEVERE THUNDERSTORM WATCH 518...

VALID 250142Z - 250215Z

NEW WW IS BEING CONSIDERED FOR ERN NEB/FAR SERN SD EWD ACROSS NRN
IA.  THIS NEW WW WOULD LIKELY REPLACE MUCH OF WW 518.

01Z SURFACE ANALYSIS AND REGIONAL RADAR DATA INDICATED STORMS OVER
CENTRAL IA MAY BE SLIGHTLY ELEVATED...GIVEN THAT THEY ARE DEVELOPING
NORTH OF AN OUTFLOW BOUNDARY WHICH WAS TRACKING SWD THROUGH CENTRAL
IA NEAR THE DSM AREA.  ADDITIONAL STORMS DEVELOPING FROM NWRN TO
NERN IA APPEAR TO BE ALONG/N OF THE PRIMARY SYNOPTIC BOUNDARY...WITH
THE ACTIVITY OVER NWRN IA BEING AIDED BY STRENGTHENING LLJ NOSING
INTO ERN NEB.  

THUNDERSTORMS WILL CONTINUE TO DEVELOP OVER ERN NEB INTO PORTIONS OF
WRN TO NRN IA OVERNIGHT AS INDICATED BY CURRENT RADAR TRENDS AND
FORECAST BY SHORT TERM MODELS. MODERATE ELEVATED INSTABILITY
COMBINED WITH 35-50 KT OF EFFECTIVE BULK SHEAR SUGGEST STORM
ORGANIZATION WILL BE LIKELY WITH THE THREAT FOR HAIL AND DAMAGING
WINDS WITH THE STRONGEST STORMS.
