VALID 071806Z - 072000Z SVR THREAT WILL CONTINUE OVER MUCH OF WW 425 THROUGH 21Z. AIRMASS DOWNSTREAM OF WEAKENING CONVECTIVE LINE OVER WRN WI REMAINS MODERATELY UNSTABLE WITH MUCAPE VALUES AROUND 3000 J/KG. WEAKENING INHIBITION IS EVIDENT BY RECENT TRENDS OF REDEVELOPMENT OF STRONG/ISOLATED SVR STORMS ALONG GUST FRONT/OUTFLOW OVER CENTRAL WI. WELL DEFINED CONVERGENCE ALONG THE OUTFLOW BOUNDARY SHOULD CONTINUE TO SUPPORT MORE SVR TSTM DEVELOPMENT ALONG THIS BOUNDARY FROM SWRN WI ENEWD INTO CENTRAL WI OVER THE NEXT FEW HOURS. GREATEST SVR HAIL POTENTIAL WILL REMAIN OVER SWRN PORTIONS OF WW 425...WHERE STEEPER MID LEVEL LAPSE RATES AND STRONGER MID LVL FLOW/DEEP LAYER SHEAR EXISTS.
