The warmth isn’t leaving Chicagoland any time soon.
Monday will bring more sunshine and unseasonably warm conditions, with highs reaching the mid- to upper 80s inland and 70s along the lakefront.
Tuesday, the final day of September, is also expected to stay above average, providing a summerlike close to the month.

Next Few Hours
Extended Outlook
A dip in temps is expected for the start of October on Wednesday, with highs dropping into the more seasonal 70s all the way through Thursday. Still, temps will be warmer than normal.
Then, they’re forecast to climb right back up for the end of the coming work week and into next weekend, with the early forecast showing highs soaring well into the 80s by Friday and Saturday.
Rainfall deficit
Unfortunately, there’s no rainfall in site in the near future for Chicagoland, at least for now.
We’re running a significant rainfall deficit, with the city receiving just about a half-inch of rain since the start of September. As you can see below, that’s around 2 inches or more below the usual amount so far for the month.
Not surprisingly, drought conditions continue to persist around Chicagoland:
Zero rainfall is in sight across a large portion of the Midwest for at least the next week, which will only exacerbate the current drought conditions in place:
Forecast maximum temperature anomaly: Sunday, Sept. 28 through Thurs., Oct. 2
Well above normal temperatures will be present throughout the Northern Plains, Upper Midwest, Great Lakes and even portions of the Northeast:
Forecast 850-millibar (1 mile above the surface) temperature anomaly
This is a good proxy indicator of how temperatures will perform at the surface. The red and orange shading represents areas of above to much above normal, while blue shading depicts areas of cooler than normal.
Above normal temperatures are in firm control for at least the next seven to eight days, with some minor cooling possible later next weekend, the first full weekend of October:
