This Hazardous Weather Outlook is for portions of north central
Illinois...northwest Illinois...west central Illinois...east
central Iowa...northeast Iowa...southeast Iowa and northeast
Missouri.

.DAY ONE...TODAY AND TONIGHT

Areas of dense fog will occur across portions of the outlook area
early this morning, reducing visibilities to a quarter mile or
less. The fog will then begin to lift by 9 AM CST.

Unseasonably warm temperatures, breezy southwest winds gusting up
to 25 MPH, low relative humidities, and plentiful dried vegetation
will combine to result in a very high threat of grass fires by
this afternoon.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY

Thunderstorms will be possible from late Thursday into Friday as
a large storm system moves across the Midwest. Chances for severe
weather Thursday night are low, but locally heavy rainfall may
produce ponding of water on roads. There is a chance for more
thunderstorms redeveloping east of the Mississippi River by
Friday afternoon. There is a marginal threat for some of these
storms to be severe. A higher chance for severe weather will
occur to the east of the Outlook Area Friday afternoon.

A strong cold front will arrive late Friday, resulting in rain
changing over to snow Friday night and into early Saturday
morning. Snow accumulations are currently expected to be light,
but brisk northwest winds mixing in with the snow may sharply
reduce visibilties at times.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight.

A Dense Fog Advisory is in effect until the middle morning hours
for far southern and southeastern Wisconsin, including Milwaukee,

dense fog pushing northeast into these areas, as well as for dense
fog lingering near Lake Michigan.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday

There are slight chances for thunderstorms Thursday night and
Friday, as strong low pressure moves toward the region.

Rainfall amounts Thursday night into Friday may cause area rivers
to rise. There is a Flood Warning at the Wisconsin River at
Portage, in effect until early next week.

Rain will change to light snow Friday night into Saturday. Only
light snow accumulations are anticipated.

414 AM CST Wed Feb 22 2017

This Hazardous Weather Outlook is for north-central and northeast
Wisconsin.

.DAY ONE...Today and Tonight

Runoff from snow melt and a recent rain will continue to
produce minor flooding along some rivers over central Wisconsin,
and slowly rising rivers over north central Wisconsin and
far northeast Wisconsin. These conditions will continue to
produce ice breakup or make ice conditions unstable on area
rivers, lakes, and reservoirs. Monitor local ice conditions and
consider securing and protecting equipment, and removing ice
shacks. Colder but closer to normal temperatures will be arriving
later this week.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday

A strong low pressure system will bring wintry precipitation to
the area from Thursday night through Saturday. This system has the
potential to bring several inches of accumulating snow to north-
central and northeast Wisconsin. The best chance for heavy snow
appears to be north of a line from Wausaukee to Marshfield. Areas
south of this line have an increased chance for a wintry mix of
snow, sleet, and freezing rain. The exact track of the low will
determine where the swath of heavy snow will end up falling,
therefore future forecasts should be closely monitored.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight.
