...Dense Fog Expanding Across Southern Wisconsin...

.An area of dense fog will continue to move northeast into the
area early this morning. This should result in areas of dense fog
into the middle morning hours.

459 AM CST Wed Feb 22 2017

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.

the pattern forecast, there is a chance that some of these could
be severe. Behind this system, some snow appears likely and it is
possible a light accumulation could occur over a part of the
region, though likely only on grassy surfaces after this current
warm stretch.
