Calumet-Manitowoc-Southern Marinette County-
Southern Oconto County-
324 PM CDT Wed Mar 23 2022

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

.DAY ONE...Tonight

Additional light freezing rain or snow showers will linger through
tonight. Additional ice accumulations of a tenth of an inch or
less are possible northwest of the Fox Valley and lakeshore areas.
Untreated roads, bridges, and overpasses may become ice covered
in parts of north central, central and far northeast Wisconsin, so
motorists should use caution.

Flows will increase on area rivers, leading to above bankfull
conditions. A couple rivers may approach minor flood stage. Some
ice jamming may occur as the increased flows lift and break up any
remaining river ice.

.DAYS TWO THROUGH SEVEN...Thursday through Wednesday

The continued runoff into area rivers will lead to bankfull
conditions on several area rivers. The chances of minor flooding
on a couple rivers will also increase through the end of the work
week and into the weekend. Some ice jamming may occur as the
increased flows lift and break up any remaining river ice.

Snow showers or snow squalls are possible on Friday afternoon and
evening which could lead to short, but sudden, road impacts due
to quick reductions in visibility and slippery conditions.

.SPOTTER INFORMATION STATEMENT...

Spotters are urged to forward any reports of freezing rain to the
National Weather Service in Green Bay tonight.
