AREAS AFFECTED...PORTIONS OF MINNESOTA AND WESTERN WISCONSIN
CONCERNING...SEVERE THUNDERSTORM WATCH 135...
VALID 232040Z - 232145Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 135
CONTINUES.
SUMMARY...STRONG TO SEVERE STORMS REMAIN LIKELY THIS AFTERNOON AND
INTO THE EVENING. DAMAGING WINDS AND HAIL ARE PROBABLE. A COUPLE OF
TORNADOES REMAIN POSSIBLE.
DISCUSSION...AS OF 2045 UTC, REGIONAL RADAR IMAGERY SHOWED A BROKEN
BAND OF STRONG TO SEVERE THUNDERSTORMS HAD DEVELOPED ALONG
PROGRESSIVE PORTIONS OF THE COLD FRONT ACROSS CENTRAL MN. THE
ENVIRONMENT DOWNSTREAM OF THESE STORMS HAS SLOWLY WARMED INTO THE
LOW 70S DESPITE PERSISTENT CLOUD COVER. WHILE BUOYANCY REMAINS ON
THE LOWER END, ~1000 J/KG MUCAPE, THIS SHOULD BE SUFFICIENT FOR A
FEW STRONGER UPDRAFTS AS STORMS CONSOLIDATE INTO A LINE. DAMAGING
GUSTS AND HAIL APPEAR TO BE THE MOST PROBABLE THREATS. LOW-LEVEL SRH
AROUND 100-200 M2/S2 COULD SUPPORT A COUPLE OF TORNADOES WITH
EMBEDDED SUPERCELLULAR STRUCTURES OR QLCS CIRCULATIONS. THE SEVERE
THREAT SHOULD CONTINUE AS THE COLD FRONT CONTINUES EASTWARD ACROSS
WW135.
