Fall In Northern Illinois: What Weather Experts Are Predicting

I know, it seems like we just got started with summer and now we're talking about autumn.

It's only the first week of August, but if you're already dreaming (or dreading if you're a hot weather lover) about football, apple cider, colorful leaves, and sweatshirt weather, you're not alone.

The first long-range forecasts for fall have arrived, and while nobody can guarantee what Mother Nature will do months in advance, several well-known weather sources are seeing some common themes for Northern Illinois for our upcoming autumn season.

Let's Start With The Almanacs And Their Predictions

The Old Farmer's Almanac says Northern Illinois and the Lower Great Lakes region should experience a cooler-than-average and somewhat drier-than-average fall.

September is expected to run a little cooler than normal with near-average rainfall, while October should stay close to average in temperature but trend slightly drier than usual. Overall, the Almanac expects a pleasant autumn with fewer soaking rains than many years.

Interestingly, the Climate Prediction Center, whose outlook is referenced alongside the Almanac's forecast, isn't predicting any dramatic departures from normal across much of the Midwest. That suggests we may avoid prolonged stretches of unusual heat or early-season cold, even if individual weeks swing above or below average.

Here's What The Meteorologists Are Thinking

As for AccuWeather and The Weather Channel, both have indicated that while warm spells are still likely during September, the transition into true fall should be fairly gradual rather than abrupt. They also point to a developing El Niño pattern that could begin influencing weather as autumn progresses, although its biggest effects are expected to show up during the winter months instead of early fall.

Of course, there's an important reminder whenever seasonal forecasts come out: they're meant to describe overall trends, not what the weather will be on a particular day. Illinois has a habit of throwing everyone a curveball. We've seen Halloween snowstorms, 85-degree October afternoons, and everything in between.

So, if the long-range outlooks are on the right track, Northern Illinois could be in for a classic fall with comfortable temperatures, relatively dry conditions, and plenty of opportunities to enjoy the changing leaves before winter eventually takes over.

Although in Illinois it's probably wise to keep both a light jacket and a pair of shorts handy.
