Hydrologic Outlook
ESFLOT Waves of showers and thunderstorms are likely late today into Wednesday, and particularly this evening. Some storms may produce rainfall rates in excess of 1 to 2 inches per hour, which could lead to localized flooding. The locations with the highest risk of flooding remain somewhat uncertain. The highest probability of heavy rainfall is generally along and south of I-80, but drought conditions worsen toward Livingston, Ford, Iroquois, and Benton counties. Drought conditions increase the rainfall rates needed to cause flood impact. Closer to the Chicago Metropolitan Area, lower rainfall rates would be required to cause flood impacts. This outlook means that elevated water levels and potential impacts are possible, but not yet certain. Persons should closely monitor forecasts including the possibility of flood watches, warnings, and advisories.
Dense Fog Advisory
* WHAT...Visibility less than one quarter mile in dense fog. * WHERE...Boone, De Kalb, Lee, Ogle, Winnebago, Kane, and McHenry Counties. * WHEN...Until 11 AM CDT this morning. * IMPACTS...Low visibility could make driving conditions hazardous.
Special Weather Statement
Pockets of fog, locally reducing visibilities under one half mile, will be possible early this morning. If traveling, be prepared for sudden changes in visibility. If you encounter fog, slow down, maintain a safe following distance, and use your low beam headlights.

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.

Special Weather Statement
Snow will end from north to south across the area early this morning. The threat of accumulating snow will end north of I-80 by 7 AM and across northwest Indiana by 830 AM. Behind the snow, lingering very fine light snow, snizzle, or very light freezing drizzle may linger for a couple of hours. If precipitation were to change to all freezing drizzle, the threat of icing on surfaces appears low since it would likely be light and temperatures will be warming to near freezing.
Special Weather Statement
A fast moving weather system will produce a short 3 to 5 hour period of accumulating snow overnight into early Friday morning. While significant snowfall amounts are not expected, a burst of snow, with rates up to 1 inch per hour, could result in a period of slick travel due to snow covered roads early Friday morning. Patchy freezing drizzle is also possible. Accordingly, motorists are urged to plan for extra time to reach their destination Friday morning.
Special Weather Statement
A fast moving weather system will produce a short 3 to 5 hour period of freezing drizzle overnight into early Friday morning.

Special Weather Statement
A band of snow will spread across the area this evening resulting in a coating to a half inch of snow. Immediately behind the snow there could be a 2 to 3 hour period of freezing drizzle which may result in slippery travel especially on untreated and elevated surfaces. If traveling this evening or overnight use caution and allow for extra travel time to reach your destination.
