   Areas affected...Northern IL...Northern IN...Southwest Lower MI

   Concerning...Severe potential...Watch unlikely 

   Valid 250114Z - 250315Z

   Probability of Watch Issuance...20 percent

   SUMMARY...A few strong/severe wind gusts are possible the next few
   hours as convection propagates southeast. Severe thunderstorm watch
   is not currently warranted.

   DISCUSSION...Multi-faceted complex of storms that originated over
   the upper MS Valley earlier today has progressed southeast and
   currently extends along a corridor from southwest lower MI-northwest
   IN-northern IL. Severe wind gusts were more common with this
   activity across portions of IA/northern IL late this afternoon, but
   have recently waned in intensity with many storms now producing
   gusts on the order of 35kt. This elongated corridor of convection is
   propagating southeast at roughly 20-25kt and should continue for the
   next few hours as sufficient cold pool trails the leading storms.
   Given the generally sub-severe wind reports, at this time a new
   severe thunderstorm watch is not warranted.
