C: Mchenrycountywx | L: Woodstock | PL: McHenry County WX WWUS83 KLOT 171945 RFWLOT URGENT - FIRE WEATHER MESSAGE National Weather Service Chicago IL 145 PM CST Tue Feb 17 2026 ...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. /O.NEW.KLOT.FW.A.0001.260218T1500Z-260219T0200Z/ Winnebago-Boone-McHenry-Lake IL-Ogle-Lee-De Kalb-Kane-DuPage-Cook- La Salle-Kendall-Grundy-Will- 145 PM CST Tue Feb 17 2026 ...FIRE WEATHER WATCH IN EFFECT FROM WEDNESDAY MORNING THROUGH WEDNESDAY EVENING...
