Fall Weather in Chicago: Unseasonably Warm Temperatures Persist

Some signs of fall are visible across the Chicago area – the Halloween decorations are up and leaves are starting to change, but one major indicator is missing: cooler temperatures.

Weekend Weather Forecast

This weekend will be another one of summer-like weather, with readings nearly reaching a record at just below 90 degrees. Most of the region will experience high temperatures in the upper 80s on Saturday, NBC 5 Storm Team Meteorologist Pete Sack said. Conditions could be slightly cooler along Lake Michigan, with a breeze arriving from the south causing temperatures to drop a few degrees.

But by and large, those gusts from the south are going to hold those lake breezes at bay, Sack said.

Temperature-wise, the well-above-normal readings are in line with a trend occurring in most of the country’s midsection, and it’s expected to continue for a few more days. Evening conditions will be favorable for those considering outdoor plans, as beautiful weather is slated to arrive and persist through the morning.

Sunday will be slightly breezier, with winds out of the southwest between 12 and 22 miles per hour. However, breezes will likely be the only noticeable change compared to Saturday, as sunshine will prevail throughout the majority of the day.

Temperature Fluctuations

The day will start off warm overall, with temperatures bottoming out in the low 60s away from the lake and values in the upper 60s in Chicago. Otherwise, temperatures will be well above normal for this time of year, with readings in the low-to-mid 80s beginning in the afternoon.

That will come to an end shortly after, as a cold front moves in and changes temperatures slightly; readings are expected to drop a few degrees.

Rain and Storms

While we’ve experienced dry conditions for a while, that will change too.

There won’t be a concern of rain for the morning commute, but a few scattered showers may arrive in the afternoon on Monday. In the later afternoon hours specifically, we’ll have the opportunity for showers and a few storms to develop, Sack said.

Readings will sit in the mid-80s on Monday, but it will be cooler in some north and northwest communities; temperatures could drop as low as the upper 60s in some spots.

Weekly Weather Outlook

A chance of storms will also arrive Monday night and into Tuesday morning, though it will move out pretty quickly; dry conditions will arrive by the afternoon hours.

The rest of the week will likely stay dry, though it’ll be noticeably chillier with temperatures in the 60s on Tuesday and continuing through the middle part of the week. By the time next weekend rolls around, we will encounter a slight warm-up, with temperatures surpassing the 70-degree mark.

Conclusion

In conclusion, the Chicago area is experiencing unseasonably warm temperatures, with summer-like weather expected to continue through the weekend and into Monday. While a cold front will bring some changes, the area will still experience above-normal temperatures. It’s essential to stay informed about the weather conditions and plan accordingly, especially with the heightened fire danger and potential for rain and storms.
