AREAS AFFECTED...CNTRL AND ERN WI THROUGH WRN PARTS OF UPPER MI
CONCERNING...SEVERE THUNDERSTORM WATCH 773...
VALID 300032Z - 300130Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 773
CONTINUES.
CONVECTIVE TRENDS WILL LIKELY CONTINUE DOWNWARD ACROSS REMAINING
PARTS OF WW 773. STORMS ARE INCREASING IN COVERAGE AND INTENSITY
SOUTH OF THE WW OVER SRN WI. SOME OF THIS ACTIVITY MIGHT BECOME
CAPABLE OF PRODUCING ISOLATED DAMAGING WIND AND HAIL. THE DURATION
AND EXTENT OF SEVERE THREAT SOUTH OF WW 773 WILL PROBABLY NOT BE
SUFFICIENT TO WARRANT ANOTHER WW ISSUANCE...BUT TRENDS ARE BEING
MONITORED.
STORMS THAT DEVELOPED ACROSS CNTRL WI NWD THROUGH UPPER MI WITHIN
PRE-FRONTAL WARM SECTOR AND ZONE OF ASCENT ASSOCIATED WITH EWD
MOVING SHORTWAVE TROUGH CONTINUE A DECREASING TREND. INSTABILITY
WILL REMAIN LIMITED IN THIS REGION WITH THE ONSET OF NOCTURNAL
COOLING AND POTENTIAL FOR FURTHER STORM INTENSIFICATION WILL REMAIN
LIMITED.
FARTHER SOUTH...STORMS ARE INCREASING ACROSS SRN WI ON NRN END OF
MCS WHERE THE WARM SECTOR HAS NOT YET BEEN OVERTURNED. OTHER STORMS
ARE DEVELOPING ALONG SWRN EXTENTION OF THE COLD FRONT FROM W CNTRL
WI SWWD INTO NRN IA. THESE STORMS ARE MOVING SEWD AND WILL LIKELY
EVENTUALLY MERGE WITH SOME OF THE STORMS DEVELOPING FARTHER SOUTH
AND SPREADING NEWD. A SMALL 2 HOUR WINDOW WILL EXIST FOR ISOLATED
SEVERE EVENTS OVER SRN WI WITH STORM MERGERS POSSIBLE BEFORE RAPIDLY
WEAKENING.
