Via the Illinois State Climatologist, NOAA has put out a two-page brochure outlining the El Niño forecast for this coming winter, and its benefits to the Chicago area:
While no two El Niño events are alike, the typical winter weather pattern brings the polar jet stream farther north than usual, across Canada, while the Pacific jet stream remains in the southern U.S. As a result, the upper Midwest to Great Lakes area can be warmer than normal, with drier-than-normal conditions across the Great Lakes toward the Ohio River Valley, and with less snow than usual in the upper Midwest Confidence in these patterns is higher with stronger El Niño events.
Odds still favor an El Niño forming by mid to late fall, with a 60-70% chance of development. There is a 30-40% chance for neutral conditions to continue through this winter, with a near-zero chance for La Niña to develop.
After last year's brutal winter, the worst we've had in 35 years, the phrase "warmer and drier than normal" sounds great. I vote Yes.
