SUMMARY...BOWING MCS WITH A HISTORY OF PRODUCING LONG SWATHS OF DAMAGING WINDS CONTINUES TO MOVE E ACROSS THE UPPER MIDWEST AT 30-40 KT. SEVERE WEATHER THREAT FOR WW 358 IS EXPECTED TO CONTINUE...WITH A NEW WW ISSUANCE POSSIBLE OVER SERN LOWER MI INTO NRN PORTIONS OF OH. DISCUSSION...A FAST MOVING BOW ECHO WAS LOCATED FROM SWRN LOWER MI INTO NRN/CNTRL IN AND FAR E-CNTRL IL AT 01Z. AIRMASS DOWNSTREAM /PER ILN AND DTX 00Z RAOBS/ IS CHARACTERIZED BY TEMPERATURES IN THE 80S...AND DEWPOINTS GENERALLY IN THE UPPER 60S...WHICH SUPPORTS MLCAPE VALUES FROM 1000-1500 J/KG. THOUGH THE BOW ECHO HAS SHOWN A WEAKENING TREND DURING THE LAST HOUR...ELONGATION OF THE COLD POOL DOWNSTREAM INTO THE MODERATE INSTABILITY ENVIRONMENT WILL CONTINUE TO FAVOR UPDRAFT REGENERATION ALONG THE GUST FRONT AND MAINTAIN A RISK FOR DAMAGING WINDS.
