WEATHER EVENT RECAP: Sugar Grove Sees Highest Wind Gusts, 1 Brief Tornado Tuesday

5PM WEDNESDAY UPDATE

Fast Facts:

  • The remnants of Tropical Storm Cristobal, that made landfall in Louisiana on June 7, brought gusty winds to northern Illinois and northwest Indiana that were enhanced to damaging levels under stronger showers.
  • During the mid-afternoon through early evening there were multiple arcs of showers (with little to no lightning) that produced scattered wind damage, especially in Cook County including parts of Chicago.
  • One brief tornado was reported near the Ford and Iroquois County border in rural east central Illinois near the town of Onarga.
  • It is not that uncommon for remnant tropical systems to impact the area, averaging about once every 8-9 years going back to the late 1880s. See our page on Climatology of Tropical Cyclone Remnants for the Local Area.

Here’s the latest from the National Weather Service Chicago’s Weather Story, as of 5 p.m. Tuesday.

Timing of Severe Storms, Strong Winds

Here is a graphic showing the approximate timing of the hazards that are expected with Cristobal’s remnants today and another system that will move over the area on Wednesday.

The primary timing of impacts are from mid-afternoon through late-evening today.

Severe Weather Risk

Isolated severe thunderstorms will remain possible this evening.

There were already some earlier (in fact were just showers!), and if any can redevelop, the primary risks would be damaging winds with gusts up to 70 mph and possibly a tornado or two.

Heavy Rainfall

Brief, but torrential downpours are expected with some of the Cristobal’s rain bands that will affect the area this afternoon and evening.

Widespread flooding is not expected, but some localized flash flooding may occur with the highest risk for this being mainly northwest of I-57, particularly across north central IL.
