Wind Advisory
* WHAT...West winds 20 to 30 mph with gusts up to 45 mph expected. * WHERE...Boone, De Kalb, Lee, Central Cook, DuPage, Kane, Lake IL, McHenry, and Northern Cook Counties. * WHEN...Until 6 PM CST this evening. * IMPACTS...Gusty winds will blow around unsecured objects. Tree limbs could be blown down and a few power outages may result.
Special Weather Statement
ELEVATED FIRE WEATHER CONDITIONS EXPECTED FOR MUCH OF SOUTHERN WI... Clearing skies during the day Wednesday will lead to strong mixing and thus relative humidities are expected to plummet to 15-25% with very breezy winds (gusts to 40mph). This will lead to an increased concern for fire weather.
Red Flag Warning
...RED FLAG WARNING EXPANDED TO INCLUDE CHICAGO METRO... Conditions will turn very dry and windy this afternoon, making conditions supportive of brush fire spread. Even with rainfall last night generally 0.05 to 0.15 of an inch across northeastern Illinois, the combination of warm, dry, and windy conditions will cause fine fuels to dry out by early afternoon. As a result, the Red Flag Warning was expanded to include Cook, DuPage, Will, Kankakee, and Lake (IL) Counties until 8 PM this evening. The National Weather Service in Chicago has issued a Red Flag Warning, which is in effect until 8 PM CST this evening. * Affected Area...Lake IL, DuPage, Cook, Will and Kankakee. * Timing...Until 8 PM CST this evening. * Winds...Southwest 20 to 30 mph with gusts up to 45 mph. * Relative Humidity...As low as 15 to 20 percent. * Impacts...Any fire that develops will catch and spread quickly. Outdoor burning is not recommended.
Special Weather Statement
The combination of unseasonably warm temperatures, low relative humidity and gusty westerly winds will lead to a heightened threat of brush fire ignition and spread this afternoon. Any fires that ignite may become difficult to control. Outdoor burning is strongly discouraged.
Red Flag Warning
The National Weather Service in Chicago has issued a Red Flag Warning, which is in effect from 10 AM this morning to 8 PM CST this evening. This replaces the Fire Weather Watch that was previously in effect. * Affected Area...Winnebago, Boone, McHenry, Ogle, Lee, De Kalb, Kane, La Salle, Kendall and Grundy. * Timing...From 10 AM this morning to 8 PM CST this evening. * Winds...West 20 to 30 mph with gusts up to 40 to 45 mph. * Relative Humidity...As low as 15 to 20 percent. * Impacts...Any fire that develops will catch and spread quickly. Outdoor burning is not recommended.
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
A band of light snow this evening (expected accumulations up to 1/2 inch) will be followed by a period of freezing drizzle tonight into early Monday morning. Expecting roads that are not snow covered or treated to become slick with freezing drizzle. Precipitation will end west to east early Monday morning. Leave extra time for travel tonight and use extra caution, as conditions may be slippery due to the combination of snow and freezing drizzle.
Winter Weather Advisory
* WHAT...Two periods of accumulating lake effect snow expected. Total snow accumulations could locally exceed 5 inches, particularly near the lake. * WHERE...Northern Cook County. * WHEN...For the first Winter Weather Advisory, until 8 PM CST this evening. For the second Winter Weather Advisory, from 6 AM to 4 PM CST Saturday. * IMPACTS...Roads, and especially bridges and overpasses, will likely become slick and hazardous. The hazardous conditions will impact this evenings commute. * ADDITIONAL DETAILS...Lake effect snow is expected to impact the area in two waves. The first will persist through this evening, before the lake effect band shifts east into Indiana for a period overnight. The band of snow is then expected to shift back westward into parts of northeastern Illinois Saturday morning. This will likely result in additional localized accumulations and travel impacts.
Winter Storm Warning
* WHAT...For the Winter Storm Warning through this evening, heavy lake effect snow. Snow accumulations locally in excess of 6 inches, particularly near the lake. For the Winter Weather Advisory on Saturday, another round of lake effect snow, with additional localized accumulations in excess of 3 inches possible. * WHERE...Central Cook and Southern Cook Counties. * WHEN...For the Winter Storm Warning, until midnight CST tonight. For the Winter Weather Advisory, from 6 AM to 4 PM CST Saturday. * IMPACTS...Travel will remain hazardous at times into this evening, particularly near the lake. Additional localized adverse impacts to travel are likely at times on Saturday. * ADDITIONAL DETAILS...Accumulating lake effect snow will continue into this evening, and will fall locally at 1 to 2 inch per hour rates at times, making for hazardous travel conditions. This will particularly be the case for areas in close proximity to the lake. This intense band of lake effect snow is expected to shift eastward into northwestern Indiana late this evening and overnight, thus resulting in a several hour break in accumulating snow across Cook county overnight. However, the band is expected to shift back westward Saturday morning, and is expected to impact parts of northeastern Illinois on Saturday. While the footprint of accumulating snow is likely to be lower on Saturday, localized additional accumulations and associated travel impacts are expected.

This will make for hazardous travel conditions. While a short break in the heavy snow is possible for a period this afternoon, a second round of intense lake effect snow is expected to bring at least a few hour period of snowfall rates up to 2 inches per hour this evening. Finally, the lake effect snow band may shift back westward along the state line and bring another period of heavy lake effect snow for several hours Saturday morning.

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.
