Chicago residents are currently basking in the warmth of an unseasonably sunny day, enjoying temperatures that have soared into the upper 70s, with the potential to hit the 80s in some areas, according to the National Weather Service (NWS). These summer-like conditions are set to continue through Monday, as mentioned in a detailed forecast. However, the NWS has issued a hazardous weather outlook warning of an elevated fire weather risk, particularly northwest of I-55 for the afternoon due to dry conditions and breezy southwesterly winds.
