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...TONIGHT

Scattered thunderstorms are expected tonight. Hail is the primary
threat, with a low risk for large hail.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY

A strong cold front will arrive Friday, resulting in rain changing
over to snow. The change over is expected to start Friday morning
northwest of a Cedar Rapids to Dubuque line, then continuing to
progress to the east across the rest of the area Friday afternoon
into early Saturday morning. A wintry mix followed by several inches
of snow accumulation is likely for portions of northeast Iowa, and a
winter weather advisory has been posted for areas mainly along and
northwest of a Dubuque to Cedar Rapids line from Friday morning to
Saturday morning. Travel conditions in these areas will become
hazardous due to icy and snow covered roads, along with reduced
visibilities in the snowfall. Elsewhere, any snow accumulations
Friday night into Saturday morning are expected to be on the light
side, but brisk northwest winds mixing in with the snowfall may
sharply reduce visibilities at times. Some localized slick spots may
also develop on roads later Friday night through Saturday morning.

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.

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 tonight.
