Chicago woke up Sunday under a smoky haze that trimmed visibility and cast a milky orange filter along the lakefront. Temperatures are holding in the low to mid 70s near the water and running warmer inland, but the bigger headline is the smoke, which officials say will linger through the day. Rough conditions are building along local beaches, and forecasters are eyeing a stronger system that could deliver storms Monday night. Anyone with breathing issues, and anyone planning outdoor events, should be ready to pivot.
Today's Forecast
Skies should be mostly sunny this afternoon, with highs near 76°F away from the lake and in the lower 70s along the shoreline. Light northeast winds around 5-10 mph will keep the smoky plume hanging over the region. Rain chances stay very low through this evening.

Air Quality And Health
The Illinois EPA has issued an Areawide Air Pollution Action Day for Sunday, as fine particles from wildfires have pushed parts of the region into the Unhealthy for Sensitive Groups category. People with asthma, heart disease, older adults, and young children are advised to shorten or move strenuous activities indoors and keep quick-relief medication close at hand. For current air quality readings and NowCast updates, check the Illinois EPA.
Lake Hazards And Storms Ahead
A Beach Hazards Statement remains in effect for southern Lake Michigan beaches through at least midday Sunday, with waves running about 3-5 feet and dangerous currents making swimming risky. “Remain out of the water to avoid dangerous swimming conditions and do not venture out onto piers, jetties, breakwalls, or other shoreline structures,” the National Weather Service warns.
Looking ahead, a stronger system is expected to move in Monday evening, with showers and thunderstorms likely. Forecasters say the main severe threat will be damaging winds, with hail and an isolated tornado possible in any surface-based storms. Heavy downpours could also trigger brief, localized flooding in some spots. For the full slate of hazards and the latest updates, see the National Weather Service.
What You Should Do
For Sunday, consider shifting outdoor plans indoors and holding off on any beach trips until conditions settle down. Keep tabs on updated forecasts and hourly AQI readings, and follow local advisories. For more background on the smoke choking Chicago, see our earlier coverage.
If you have to be outside Monday evening, keep an eye on the sky, have a quick shelter option in mind in case thunderstorms turn severe, and check for fresh updates before you head out.
