   Mesoscale Discussion 0105
   NWS Storm Prediction Center Norman OK
   0914 AM CST Wed Jan 25 2023

   Areas affected...portions of central and northeast Indiana into
   southeastern Lower Michigan

   Concerning...Heavy snow 

   Valid 251514Z - 252045Z

   SUMMARY...Moderate to heavy snow should continue northeast across
   central and northern IN, extreme northwest OH, and far southeast
   Lower Michigan into the mid-afternoon hours. A few instances of 1+
   inch/hr snowfall rates are possible in the heavier bands.

   DISCUSSION...A surface low is centered around the IN/KY border and
   is poised to continue drifting northeast toward Lake Ontario through
   the day while also intensifying. Strong surface-700 mb
   warm-air/moisture advection will continue to feed relatively rich
   moisture to the dendritic growth zone (-12 to -17C layer). Upglide
   of this moisture while wrapping around the surface low should
   continue to foster at least moderate to occasional bouts of heavy
   snow through 20Z northwest of the mid-level dry slot. The heaviest
   snow (including brief instances of 1+ inch/hr snowfall rates) will
   be most likely where 700 mb frontogenesis and associated lift will
   be strongest. Latest mesoanalysis suggests that this corridor is
   situated across central into northern IN/extreme northwest OH and
   far southeast lower MI.
