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

A strong storm system will bring the threat for thunderstorms to
the area late this afternoon through Friday morning. There will
be a threat for small hail with any thunderstorm tonight. There
is a very low threat for hail up to 1 inch in southeast Iowa, and
northeast Missouri tonight.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY

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. The change over is expected to start late
Friday afternoon northwest of a Cedar Rapids and Dubuque line,
then continuing to progress to the east across the rest of the
area Friday night and into early Saturday morning. Snow
accumulations are still expected to be on the light side, but
brisk northwest winds mixing in with the snow may sharply reduce
visibilities at times. Some localized slick spots may also develop
on roads later Friday night, especially north of the Interstate
80 corridor.

There is still some uncertainty on the exact track of the storm
system on Friday, and any deviation from the currently expected
path will be a factor on eventual snowfall amounts and placement
Friday afternoon and night. Stay tuned for further updates and
forecasts concerning this end of week winter storm system.

More light snow or a wintry mix will be possible across portions
of the Outlook area Sunday afternoon and evening.

River flooding will be possible in the several days based upon
forecast rainfall. There is low confidence on the river forecasts,
but minor flooding is possible on portions of the Iowa and Cedar
Rivers.

.SPOTTER INFORMATION STATEMENT...

There is low chance for spotter activation this afternoon and
tonight.
