   Mesoscale Discussion 1293
   NWS Storm Prediction Center Norman OK
   0356 AM CDT Wed Jul 12 2017

   Areas affected...Parts central WI

   Concerning...Severe potential...Watch possible 

   Valid 120856Z - 121130Z

   Probability of Watch Issuance...40 percent

   SUMMARY...Fast-moving (45 kt) bowing line of storms located in
   Barron to Rusk to western Eau Claire counties will affect parts of
   central WI between 09-12Z, with a new WW being considered.

   DISCUSSION...Two clusters of storms merged over east-central MN and
   surged eastward into west-central WI along a moderate instability
   gradient, producing damaging winds (trees and wires down).  This bow
   will continue to be capable of producing damaging winds into part of
   central WI between 09-11Z, though a more stable air mass with
   eastward extent may limit the threat too far east into northeast WI.
   Otherwise, this bow may tend to turn to the southeast along the
   instability gradient and decelerate as it moves into ongoing
   downstream storms.
