Fire Weather Watch
...A FIRE WEATHER WATCH IS IN EFFECT FOR WEDNESDAY...
The combination of unseasonably warm temperatures (highs in the
60s), dry conditions (RH values around 15-25%), and gusty west-
southwest winds (gusting around 35-40 mph) will lead to an
elevated fire danger on Wednesday. While fuel moistures may be
more questionable in some areas, local fire agencies indicate
that finer fuels are primed and could lead to rapid fire spread
in these conditions. For this reason, a Fire Weather Watch has
been issued for portions of northern Illinois on Wednesday.
Confidence in Red Flag Warning criteria being met is currently
highest along and north of Interstate 88.
* Affected Area...Winnebago, Boone, McHenry, Lake IL, Ogle, Lee,
De Kalb, Kane, DuPage, Cook, La Salle, Kendall, Grundy and
Will.
* Timing...From 9 AM CST Wednesday through Wednesday evening.
* Winds...Southwest 15 to 25 mph with gusts up to 40 to 45 mph.
* Relative Humidity...As low as 15 percent.
* Impacts...Any fire that develops will catch and spread
quickly. Outdoor burning is not recommended.

Special Weather Statement
Areas of freezing drizzle will continue to move across the area
through 2 AM CST, before waning and moving off to the east.
This includes portions of Interstate 80 from the Quad Cities on
eastward into Illinois.
The freezing drizzle will gradually come to an end overnight. The
impact of the freezing drizzle and any ice glazing will be
greatest for roads that are not covered in snow already or have
treatments down for melting.
Be careful if moving about overnight as conditions may be more
slippery due to the combination of light snow cover and freezing
drizzle.
From: Feb 02, 2026 04:54
Until: Feb 02, 2026 08:00
Special Weather Statement
As snow moves east through the area, it will transition to
freezing drizzle.

evening. The impact of the freezing drizzle and any ice glazing
will be greatest for roads that are not covered in snow already or
have treatments down for melting.
Be careful if moving about this this evening as conditions may be
more slippery due to the combination of snow and freezing drizzle.

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.
