'Super' El Niño Winter Weather Outlook Is Here, What Does It Mean for Chicago?
The National Oceanic and Atmospheric Administration issued its winter weather outlook Thursday, predicting a milder season for Chicago driven by a historically strong El Niño building across the Pacific Ocean.
El Niño occurs when abnormally warm water temperatures in the Pacific Ocean lead to global weather pattern changes. This phenomenon shifts the jet stream, often pushing warmer air toward North America.
For the Chicago area, forecasters predict a 50% to 60% chance of above-normal temperatures this winter. The National Weather Service warned that even in a mild winter, residents should expect "notable" stretches of cold weather and winter precipitation.
While holiday traditions like the City of Chicago Christmas Tree Lighting will proceed as planned, activities like sledding and calling "dibs" might look different. The park district may produce fake snow for the Sledding Hill at Soldier Field.
Experts suggest climate change may be making El Niño events more dramatic. With a "super" El Niño at play, Chicago's weather could bring wide temperature swings, reminding residents of warming environment impacts.
Chicago will record less snow due to the phenomenon "Super Niño", although it will keep an intense cold wave this winter. The event reaches a historic level.
