BULK OF MCS HAS MOVED THROUGH WW WITH OCCASIONAL SVR GUSTS MEASURED
AND SEVERAL DAMAGING WIND REPORTS.  THREAT EXISTS FOR ISOLATED
DAMAGING GUSTS ALONG SRN TIER OF COUNTIES IN WW FOR ANOTHER 1-2
HOURS...AND SWD TO AREAS NW OF A ALO-DSM LINE THROUGH AROUND 8Z. 
AIR MASS AHEAD OF THIS ACTIVITY REMAINS QUITE MOIST AND FAVORABLY
BUOYANT...ESPECIALLY FOR PARCELS ROOTED ABOVE SFC...I.E. ELEVATED
MUCAPES 2500-4000 J/KG.  HOWEVER...GUST FRONTS CONTINUE TO SURGE
AHEAD OS STRONGEST REFLECTIVITIES...AND DIABATIC COOLING WILL
CONTINUE TO DEEPEN AND INTENSIFY STATICALLY STABLE LAYER NEAR SFC. 
THEREFORE EXPECT SLOWLY DIMINISHING POTENTIAL FOR SVR GUSTS TO REACH
SFC.  WW MAY BE CLEARED/CANCELED BEHIND BULK OF MCS ACROSS
N-CENTRAL/NERN IA...BEFORE SCHEDULED 6Z EXPIRATION.

..EDWARDS.. 08/02/2006
