   Mesoscale Discussion 0301
   NWS Storm Prediction Center Norman OK
   0205 PM CDT Sun Mar 30 2025

   Areas affected...Portions of eastern Illinois into central/northern
   Indiana and southwest Lower Michigan

   Concerning...Tornado Watch 70...71...

   Valid 301905Z - 302100Z

   The severe weather threat for Tornado Watch 70, 71 continues.

   SUMMARY...There is an increasing risk for severe wind gusts in
   central/northern Indiana and southern Lower Michigan.

   DISCUSSION...An organized line of storms continues to move northeast
   in parts of eastern Illinois. Several measured and estimated severe
   gusts occurred in the Champaign, IL vicinity recently. KILX radar
   shows strong outbound winds within this line. With continued surface
   heating of mostly clear/partly cloudy skies in Indiana and forcing
   from the shortwave trough, the potential for severe wind gusts
   should continue through the afternoon. Low-level shear is not overly
   strong per downstream VAD data, but QLCS tornadoes remain possible.
   The greatest potential for a tornado (and large hail) would likely
   exist on the southern flank of the line where storms may remain more
   discrete.
