AREAS AFFECTED...PORTIONS OF CENTRAL AND EASTERN WISCONSIN
CONCERNING...SEVERE THUNDERSTORM WATCH 455...
VALID 232309Z - 240045Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 455
CONTINUES.
SUMMARY...A WELL-ORGANIZED BOWING CLUSTER OF SEVERE STORMS WILL
CONTINUE TO POSE A RISK FOR DAMAGING WIND GUSTS THIS EVENING. AN
ISOLATED GUST TO 75 MPH IS ALSO POSSIBLE.
DISCUSSION...ACROSS CENTRAL WI, A CLUSTER OF THUNDERSTORMS HAS SHOWN
CONTINUED INTENSIFICATION/ORGANIZATION EARLY THIS EVENING WITHIN
WW455. NORTH OF KMSN, SINGLE SITE RADAR IMAGERY SHOWS AN
ACCELERATING BOWING CLUSTER WITH RECENT REPORTS OF DAMAGE. IN
ADDITION TO INCREASINGLY STRONG RADAR/SATELLITE FEATURES, AREA
OBSERVATIONS SHOW OUTFLOW TEMPERATURES 20-25 F COOLER BEHIND LINE,
INDICATIVE OF A WELL-FORMED AND DEEP COLD POOL. THESE CONVECTIVE
TRENDS WITHIN A VERY BUOYANT/MODERATELY SHEARED ENVIRONMENT STRONGLY
SUGGEST A CONTINUED THREAT FOR WIND DAMAGE DOWNSTREAM ACROSS CENTRAL
AND EASTERN WI OVER THE NEXT COUPLE OF HOURS. ADDITIONALLY, AN
ISOLATED SIGNIFICANT GUST TO 75 MPH IS POSSIBLE GIVEN THE INCREASED
FORWARD SPEED AND STRONG DOWNDRAFT POTENTIAL AT THE APEX OF THE
BOWING CLUSTER. GIVEN THE CONTINUED POTENTIAL FOR DAMAGING GUSTS,
WW455 WILL BE EXPANDED LOCALLY AHEAD OF THE BOW.
