   Areas affected...Eastern Iowa...northwest Illinois...and far
   southwest Wisconsin.

   Concerning...Heavy snow 

   Valid 091515Z - 091815Z

   CORRECTED FOR INCORRECT SURFACE LOW LOCATION

   SUMMARY...Moderate to heavy snow with rates of 1 to 2 inches per
   hour are expected into the early afternoon. Strong winds will lead
   to blowing, drifting, and reduced visibility.

   DISCUSSION...A 987mb surface low currently northeast of St. Louis
   this morning will continue to deepen through the day as it moves
   north into Michigan and deepens below 980mb. Within the last hour,
   snowfall rates have started to increase across eastern Iowa within
   the deformation region of the cyclone. Expect this moderate to heavy
   snow to shift eastward into northern Illinois and Wisconsin during
   the day in response to the deepening/moving cyclone. Winds are
   already around 20 mph with gusts to 30 mph but are expected to
   strengthen further to around 25 mph with gusts to 40 mph this
   afternoon as the pressure gradient tightens. Widespread blowing and
   drifting snow is expected with localized blizzard conditions
   possible.
