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

Concerning...Winter mixed precipitation=20

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.=20

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.
