   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 516 CONTINUES.
   
   TORNADO WATCH 516 CONTINUES UNTIL 07Z. THE POTENTIAL FOR A TORNADO

   NORTHERN IL AND FAR SOUTHEAST WI PORTION OF TORNADO WATCH 516. WHILE
   A TORNADO AND/OR SEVERE HAIL CANNOT BE RULED OUT...THE POTENTIAL FOR
   BOWING STRUCTURES/DAMAGING WINDS COULD INCREASE OVER THE NEXT FEW
   HOURS ACROSS NORTHERN IL/FAR SOUTHEAST WI. GIVEN THE NUMBER OF
   STORMS ALONG/EAST OF THE MISSISSIPPI RIVER...A DAMAGING WIND THREAT
   MAY BECOME MORE PROBABLE ACROSS NORTHERN IL/FAR SOUTHEAST WI GIVEN
   FURTHER COLD POOL CONGLOMERATION AMIDST A STRONGLY SHEARED
   ENVIRONMENT...ACCENTUATED BY STRONG LOW LEVEL /0-3 KM/ SHEAR OF
   30-40 KT. OTHERWISE...THE OVERALL TORNADO/HAIL/WIND THREAT SEEMS
   RATHER MARGINAL ACROSS THE BULK OF EASTERN IA AND MOST OF SOUTHERN
   WI...WITH VERY HEAVY RAINFALL/POTENTIAL FLASH FLOODING BEING THE
   PRIMARY RISK. SOUTHWESTERLY LOW TO MID TROPOSPHERIC FLOW AND
   RESULTANT NORTHEASTERLY MOVEMENTS/ECHO TRAINING AMIDST A HIGH PRECIP
   WATER ENVIRONMENT /1.93 INCHES PER 00Z DAVENPORT RAOB/ WILL CONTINUE
   TO YIELD VERY HEAVY RAINFALL OVERNIGHT.
