Chicago Weather Update

CHICAGO – Canadian wildfire smoke remains a significant factor in Chicagoland’s weather today. The smoke has been lingering in the area for some time now, and its effects can still be felt.

The sky is expected to be hazy once again, and it will be a very warm day with temperatures rising into the mid-80s. According to weather experts, smoke can hold temperatures down by 2° to 4° compared to a perfectly sunny day. The warmth will extend all the way to the beaches, making it a great day to soak up the sun. However, smoke concentrations may increase this afternoon, and some of it could be close enough to the ground to be smelled, although this is a low-probability event.

Tonight will be partly cloudy and mild, with hazy skies and lows in the mid-60s. This will provide a comfortable evening for outdoor activities, despite the lingering smoke.

Future Forecast

Looking ahead to the next few days:

Tomorrow might feature a little less smoke in the sky, allowing temperatures to climb a couple of degrees into the upper 80s. Regardless, today and tomorrow will be the warmest days since mid-May, making it an excellent time to enjoy the outdoors.

Tomorrow night, especially late, there is a chance for showers and thunderstorms. These would continue intermittently on Wednesday when cooler air will arrive. However, the risk of severe thunderstorms with this approaching system is considered low.

Another round of showers and storms will be possible Thursday night into Friday. The weekend looks dry and mild, with highs mainly in the 70s, providing a great opportunity for outdoor activities.

Understanding Chicago Wildfire Smoke

Delving deeper into the issue:

So, what happens to all the smoke in the air? It doesn’t just disappear. There are several ways this particulate matter returns to earth. It’s essential to first realize that smoke is actually composed of tiny particles. Their size is obviously very small, but some of them are larger than others. Eventually, gravity will win, and this particulate matter will come down.

The first mechanism is called “impaction.” This occurs when air currents are strong enough to force smoke particles into the ground. This process can lead to the accumulation of particulate matter in certain areas, affecting local air quality.

“Washout” occurs when rain traps smoke particles and carries them into the soil or watershed. This can have both positive and negative impacts. Nitrogen and phosphorus are nutrients for organisms, but in higher concentrations, they can be harmful. This highlights the complex relationship between wildfire smoke, precipitation, and environmental health.

Next, there is “absorption” into clouds. Many particles and gases in smoke dissolve in water and are absorbed into clouds, where they will eventually fall in rain or snow. “Gravity” alone can take larger particles, such as soil, ash, and charcoal, back to earth. This process will happen more quickly than the other mechanisms, contributing to the gradual clearance of smoke from the atmosphere.
