AREAS AFFECTED...INDIANA AND SOUTHERN LOWER MICHIGAN  
  
CONCERNING...SEVERE THUNDERSTORM WATCH 59...  
  
VALID 200048Z - 200215Z  
  
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 59  
CONTINUES.  
  
SUMMARY...LOCAL RISK FOR DAMAGING WIND GUSTS CONTINUES.  
  
DISCUSSION...LATEST RADAR LOOP SHOWS A BROKEN -- AND GRADUALLY  
WEAKENING -- BAND OF PRE-FRONTAL STORMS MOVING EASTWARD ACROSS  
CENTRAL AND NORTHERN INDIANA.  WHILE MORE VIGOROUS CELLS WITHIN THIS  
BAND PERSIST FARTHER SOUTH -- INTO PORTIONS OF TORNADO WATCH 58  
WHERE SLIGHTLY GREATER SURFACE DEWPOINTS (LOW TO MID 50S) EXIST, THE  
PRIOR, LIMITED TORNADO RISK OVER CENTRAL AND NORTHERN INDIANA HAS  
FURTHER DIMINISHED.  WHILE A BRIEF SPIN-UP IS STILL POSSIBLE, THE  
PREDOMINANT SEVERE RISK WILL REMAIN LOCALLY DAMAGING WIND GUSTS.  IN  
THE WAKE OF THE INITIAL BAND, A SECOND BAND OF FRONTAL CONVECTION  
NEAR THE ILLINOIS/INDIANA BORDER WILL REACH WESTERN FRINGES OF WW 59  
OVER THE NEXT HOUR OR SO -- WHICH MAY BRING AN ADDITIONAL CHANCE FOR  
WIND GUSTS IN EXCESS OF SEVERE LEVELS LOCALLY.  OVERALL THOUGH, A  
GRADUAL/NOCTURNAL DECREASE IN STORM INTENSITY WITHIN BOTH OF THE  
AFOREMENTIONED BANDS WILL CONTINUE OVER THE NEXT FEW HOURS.
