AREAS AFFECTED...MUCH OF SRN/CNTRL WI...FAR SERN MN...FAR NERN IA

CONCERNING...SEVERE THUNDERSTORM WATCH 411...

VALID 132309Z - 140015Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 411
CONTINUES.

SUMMARY...THREAT FOR ISOLATED SVR WIND GUSTS AND HAIL CONTINUES
ACROSS SVR TSTM WATCH 411...WITH THE MOST FAVORABLE THERMODYNAMIC
ENVIRONMENT IN PLACE ACROSS SRN WI.

DISCUSSION...RECENT RADAR LOOPS SHOW MOST PROMINENT STORM WITHIN SVR
TSTM WATCH 411 POSITIONED ACROSS RICHLAND AND SAUK COUNTIES WI...AND
IS LOCATED WITHIN A RELATIVELY HIGHER THETA-E ENVIRONMENT PER RECENT
SUBJECTIVE SFC ANALYSIS. SVR THREAT ASSOCIATED WITH THESE ONGOING
STORMS...AND DOWNSHEAR ACROSS MUCH OF SRN WI...SHOULD REMAIN
RELATIVELY MAXIMIZED HERE...WITH CONVECTION AT LEAST PARTIALLY
SUSTAINED BY WEAK LOW-LEVEL CONVERGENCE ALONG ASSOCIATED OUTFLOW AND
AN ATTENDANT LARGER-SCALE SFC TROUGH.

ONGOING TSTMS ACROSS CNTRL WI ARE MORE ISOLATED AND SMALLER
SPATIALLY...AND ARE LOCATED WITHIN A RELATIVELY LESS UNSTABLE
ENVIRONMENT AMIDST A SLIGHTLY COOLER AND LESS MOIST BOUNDARY LAYER
THAN FARTHER S. HOWEVER...CURRENT TRENDS CONTINUE TO INDICATE AT
LEAST AN ISOLATED/MARGINALLY SVR HAIL AND WIND THREAT FOR THE NEXT
COUPLE HRS.
