This Hazardous Weather Outlook is for portions of northeast
Minnesota and northwest Wisconsin.

.DAY ONE...Tonight

Light snow showers and flurries will affect the tip of the
Minnesota Arrowhead and parts of northeast Wisconsin tonight.
Accumulations should be light, generally less than an inch.
Visibilities may briefly drop below 1 mile in the heavier snow
showers.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday

Low relative humidity and gusty winds are forecast Tuesday
through Thursday and may create near-critical fire weather
conditions.

A clipper system will bring accumulating light snow chances to
portions of the Northland, with the highest accumulations south
of US Highway 2 on Thursday through Thursday night. This snow
could lead to slick roadways during the Thursday evening and
Friday morning commutes.

A messy spring storm will impact the Midwest Sunday through next
Tuesday. Accumulating snow, wintry mix, and heavy rain may all
affect the area. Travel conditions may be adversely affected.

.SPOTTER INFORMATION STATEMENT...

Snow spotters are requested to report their snowfall measurements
to the National Weather Service.

For the month of March we are actively recruiting for CoCoRaHS,
the Community Collaborative Rain, Hail, and Snow network. If you
