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. The National Weather Service in Chicago has issued a Fire Weather Watch, which is in effect from Wednesday morning through Wednesday evening. * Affected Area...Winnebago, Boone, McHenry, Lake IL, Ogle, Lee, De Kalb, Kane, DuPage, Cook, La Salle, Kendall, Grundy and Will. * Timing...From Wednesday morning through Wednesday evening. * Winds...Southwest 15 to 25 mph with gusts up to 40 mph. * Relative Humidity...As low as 15 percent. * Impacts...Any fire that develops will catch and spread quickly.

Special Weather Statement
Fog may cause visibilities to fall locally under one half mile early this morning. Use caution if out traveling. If you encounter fog, slow down, add extra stopping distance, and use your low beam headlights.
Dense Fog Advisory
* WHAT...Visibility one quarter mile or less in dense fog. * WHERE...Portions of central, east central, north central, and northeast Illinois and northwest Indiana. * WHEN...Until 9 AM CST /10 AM EST/ this morning. * IMPACTS...Low visibility could make driving conditions hazardous.
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 freezing drizzle overnight into early Friday morning. While significant ice amounts are not expected, a minor glaze of ice will be possible on untreated surfaces such as sidewalks and side streets. Accordingly, motorists and walkers should be prepared for the possibility of some slick surfaces early Friday morning.
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.

Pedestrians and motorists should use caution when walking or driving on untreated surfaces this morning, even after the freezing drizzle and mist ends.
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.
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.

Winter Weather Advisory
* WHAT...Snow expected, possibly falling heavily at times. A quick 1 to 3 inches of accumulation is expected within just a 2 or 3 hour period. * WHERE...DuPage, Lake IL, and Northern Cook Counties. * WHEN...From 9 AM to 3 PM CST Friday. * IMPACTS...Roads will likely become snow covered and travel hazardous. * ADDITIONAL DETAILS...A burst of accumulating snow is expected mid to late Friday morning through early afternoon. The snow during this period may briefly fall at a rate of up to an inch per hour and make for slick travel conditions.
Winter Storm Watch
* WHAT...For the Winter Weather Advisory, a period of snow is expected, possibly heavy at times. A quick 1 to 3 inches of accumulation is expected within a few hour period. For the Winter Storm Watch, heavy lake effect snow possible. Snow accumulations of 6 or more inches are possible, mainly east of the Dan Ryan and I-57. * WHERE...Central Cook and Southern Cook Counties. * WHEN...For the Winter Weather Advisory, from 9 AM to 3 PM CST Friday. For the Winter Storm Watch, from Friday afternoon through Friday evening. * IMPACTS...Travel will likely become hazardous as roads become snow covered during the mid to late morning through early to mid afternoon Friday. If heavy lake effect snow affects eastern Cook County late Friday afternoon and Friday evening, travel within the affected areas could be severely disrupted. * ADDITIONAL DETAILS...A burst of accumulating snow is expected mid to late Friday morning through early afternoon. The snow during this period may briefly fall at a rate of up to an inch per hour and make for hazardous travel conditions. Then, later Friday afternoon and evening, an intense band of heavy lake effect snow will develop over southern Lake Michigan, and may impact eastern portions of central and southern Cook County late Friday afternoon or evening. While the residence time of this lake effect band over Cook county may only be 3 to 5 hours, it would likely produce very heavy snow rates of 2 or more inches per hour and could result in localized accumulations exceeding 6 inches. Confidence is still low in whether eastern Cook County will be impacted by the lake effect band Friday afternoon and evening, if the band stays east over the lake into Indiana, then very little additional snow may occur.
