Brief tornadoes knock down trees, fences in DuPage and Will counties

CHICAGO - Two brief tornadoes touched down in the Chicago area on Monday as a storm system swept through northeastern Illinois.

One tornado was reported in far western Joliet and the other on the far north side of Naperville, according to the National Weather Service. Both were "brief" events.

NWS meteorologist Matt Friedlin said there have been reports of damage to trees, windows, fences and roofs but no major structural damage.

"That points towards likely that these were lower end strength, short-lived tornadoes," Friedlin said, adding meteorologists were still collecting data on the storm.

The weather service is also working to confirm reports of a tornado in the Champaign area and another in Northwest Indiana.

The twisters were part of a system that brought thunder, lightning, rain and wind gusts to the southwest and south suburbs. The weather service had issued a storm alert for those areas that went into effect at 7 a.m.

By 1 p.m., the threat of severe weather had ended, according to the weather service. But wind gusts as high as 40 mph will persist throughout the evening Monday.

We're going into the evening with temperatures in the 40s and 50s and just a few light showers around the region. Showers will come to an end Monday night, but the clouds stay put. Lows will drop into the mid 30s by daybreak Tuesday.

Tuesday looks cooler, but still mild for this time of year. Plan for partly sunny skies with highs in the upper 40s. There's a small chance of rain Tuesday evening and night, but it looks like the rain clears out for Wednesday.

Highs climb into the upper 50s on Wednesday and then plummet into the upper 30s for Thursday.

We're watching a system that will likely bring impacts to the area on Friday. Accumulating snow is a possibility.
