Mesoscale Discussion 0469
   NWS Storm Prediction Center Norman OK
   0940 AM CDT Wed Apr 17 2024

   Areas affected...far northeast IL into northern IN and southwest
   Lower MI

   Concerning...Severe potential...Watch unlikely 

   Valid 171440Z - 171545Z

   Probability of Watch Issuance...5 percent

   SUMMARY...Thunderstorms will gradually develop this morning, mainly
   across northwest IN into far southwest MI. Severe potential should
   remain low the next 1-2 hours.

   DISCUSSION...Visible satellite data and regional radar indicates
   convection is beginning to deepen ahead of the eastward advancing
   cold front. This activity will likely only slowly continue to
   intensify through the morning. Nevertheless, temperatures are
   already in the upper 60s to low 70s with weak instability noted in
   14z mesoanalysis. Severe potential is expected to remain low over
   the next couple of hours, but gusty winds to 45 mph will be possible
   with these showers and isolated thunderstorms. A watch is not
   expected in the short term, but severe potential should increase by
   around midday/early afternoon downstream.
