The Chicago area hit a record-high 82 degrees Tuesday, breaking the previous record set more than two decades ago. Tuesday's unseasonably warm weather broke the previously recorded high of 78 degrees set on Oct. 29, 1999, said meteorologist Mark Ratzer of the National Weather Service. The new record was set at 3:59 p.m. at O'Hare Airport.The warm weather brought along gusty winds, prompting a red-flag warning. The combination of high temperatures, strong winds up to 40 mph and low humidity could cause "critical fire conditions," weather officials said. If a fire were to break out, the weather could cause it to catch and spread quickly. The red-flag warning is in effect until 9 p.m. Tuesday. "Conditions today are exceptionally good for the development and spread of brush fires," said Ratzer. "No one should be out burning leaves today. These fires can spread fast and they burn hotter." Strong SW winds drive elevated fire concerns tomorrow and warm and potentially record breaking temps are possible once again.
