Hydrologic Outlook
ESFLOT
Cold temperatures this week have caused a significant increase in
river ice across the area, including multiple ice jams. Cold
temperatures are expected to continue into next week, with favorable
conditions for river ice formation. Areas of open river may see new
ice growth, while areas with existing ice cover my thicken.
No widespread flooding is expected, but ice jams will be possible in
isolated areas, especially along the Rock, Fox, and Kankakee rivers.
Ice jams may cause rises or fluctuations on area rivers with little
warning.
Persons with interests along area rivers should closely monitor the
latest forecasts.

Special Weather Statement
A strong Arctic front will move across the area this evening,
accompanied by scattered to numerous snow showers. The most
intense snow showers and localized snow squalls may briefly reduce
visibility under one half mile at times and produce a quick half
inch to locally one inch of snow accumulation. Westerly winds will
gust as high as 40 mph, which may produce blowing snow and shallow
drifting snow, especially on north to south roads in open, exposed
areas.
Motorists should be prepared to potentially encounter localized
hazardous travel conditions this evening. Before driving, pay
close attention to weather conditions and check updated road
conditions. Take it slow and keep a safe following distance when
on snow covered roads and during periods of poor visibility.

Hydrologic Outlook
ESFLOT
Recent reports from river ice spotters and river gauges indicate
that some melting of ice has occurred over the last few days, but
isolated areas of heavy river ice coverage continue. Very cold
temperatures this weekend will cause river ice to expand in
coverage. Ice jams will be possible in isolated areas along the
Rock, Fox, Des Plaines, and Kankakee rivers into early next week.
Ice jams may cause rises on area rivers with little warning.
Warmer temperatures may return to the area by late next week, which
could begin a slow melt of river ice.
This outlook means that elevated water levels and potential impacts
are possible, but not yet certain. Persons with interests along area
rivers should closely monitor the latest forecasts.
This outlook may be updated by tomorrow afternoon.
