Landspout Tornado Outlook for the Chicago Area

On June 8, 2026, the National Weather Service issued a severe weather outlook for the Chicago area that added a new kind of tornado threat: a landspout tornado. Unlike ordinary tornadoes that develop in supercell thunderstorms, landspouts can form without a towering storm cell or a wall cloud. The result is often a weaker, shorter‑lived funnel that produces little or no damage. However, if one stays on the ground for a longer period, even a brief landspout can cause minor structural damage.

Even though the forecast did not call for widespread thunderstorm development on Monday, conditions were still favorable for the formation of funnel clouds. The threat level is highest in DeKalb, LaSalle, Kendall, and Grundy counties, all west or southwest of Chicago. Residents in these areas should stay alert for “sharp, short” funnel clouds that could appear over open fields or unpaved roads.

While the potential for landspouts exists, the overall severe weather risk for the greater Chicago area remains marginal on Monday. The outlook warns that risk will increase as the week progresses. Tuesday is expected to be at a marginal risk for severe weather, while Wednesday and especially Thursday will see a higher threat of tornadoes, large hail, flash flooding, and damaging winds.

A follow‑up report on June 10 highlighted that a series of severe storm waves would sweep through the region Wednesday afternoon and night, and Thursday afternoon and evening. The first wave, beginning around 1 p.m. on Wednesday, is rated “enhanced” for severe weather across much of the city, with wind gusts up to 75 mph. Gusts of that magnitude can damage trees, bring down fences, and in some cases, produce structural damage. Meteorologists also noted a low, but still present, tornado threat during that first wave.

Heat indices are forecast to rise into the low 90s with dew points in the 70s, potentially pushing heat indices to nearly 100 degrees. The combination of high temperatures and humidity creates an ideal environment for severe storms. As Thursday’s cold front moves in, the outlook expects the chance for damaging winds and even a few strong tornadoes to rise, with the greatest risk occurring between 3 p.m. and 10 p.m.

Preparedness Tips:

• Monitor real‑time alerts from the National Weather Service. Download the official NBC Chicago app to receive push notifications directly to your phone.
• If you live in the highlighted counties, keep an eye out for sudden funnel clouds, especially during the late‑afternoon hours.
• Secure outdoor objects and lower power lines. In case of wind or storm, move to a safe indoor location.
• Have a plan for emergency shelters if a tornado or severe burst occurs overnight.

While landspout tornadoes are typically brief, they can pose a surprise threat outside of the usual thunderstorm environment. Keep a watchful eye on the weather updates, especially as the week’s temperature and humidity peak. By staying informed and prepared, residents can minimize the risk of damage and keep themselves and their families safe.
