   Areas affected...far northeast Iowa...southeast Minnesota and
   western Wisconsin.

   Concerning...Winter mixed precipitation 

   Valid 220932Z - 221330Z

   SUMMARY...Wintry precipitation will continue this morning across the
   region. Amounts should generally remain light, but may pose some
   travel issues before temperatures warm above freezing this morning.

   DISCUSSION...Light wintry mix/freezing rain has developed across the
   region this morning in response to strong warm-air
   advection/frontogenesis in the 850-700mb layer. 

   RAP point forecast soundings across Minnesota this morning depict
   surface temperatures generally near 0C/32F beneath 750mb, with
   wet-bulb temperatures generally a few degrees below 0C/32F within a
   region of low-level dry air. As the aforementioned precipitation
   moves into the area, precipitation may initially fall as sleet
   before transitioning to freezing rain or rain as persistent moist,
   warm-air advection warms and moistens the low level profile. Farther
   east/northeast, temperature profiles are colder across Wisconsin and
   should support light snow, although a mix or change to
   sleet/freezing rain/rain remains possible (especially closer to
   Minnesota) as low levels warm.

   Precipitation amounts are expected to remain generally light this
   morning. However, brief travel impacts may develop -- especially
   across Wisconsin where the colder surface temperatures reside --
   this morning before temperatures warm above 0C/32F.
