Key Messages

- Shallow fog may develop in northeastern Illinois early Tuesday morning. Any fog would dissipate a few hours after sunrise.

- An extended period of dry and above to much above average temperatures is expected through the next 7 days.

Discussion

Issued at 1223 PM CDT Mon Oct 19 2026

The only item of note is a threat for shallow fog overnight into tomorrow morning near Lake Michigan where a modestly more moist environment will advect inland. Otherwise, no significant weather is expected the next 7 days with above to much above average temperatures each day. Generally light winds should allow weak lake breezes to form each of the next several afternoons, but probably only result in slightly cooler conditions right near the lake. Other than a bit of mid-high level cloudiness this afternoon, much of the week looks to be mostly sunny.

Aviation

Issued at 615 PM CDT Mon Oct 19 2026

Light and variable winds (at times prevailing out of the east) will prevail through the TAF period. Shallow ground fog may develop in the vicinity of ORD/MDW early tomorrow morning (08-13Z timeframe). We have maintained the targeted TEMPO group for 1 1/2SM BR introduced in the 18z tafs. Otherwise, there are no aviation concerns through the TAF period.
