   MESOSCALE DISCUSSION 1398
   NWS STORM PREDICTION CENTER NORMAN OK
   0609 PM CDT MON JUL 13 2015

   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.
