Nearest Tornado Was Paw Paw

On Memorial Day, there were many tornadoes identified in Illinois and Indiana.

The nearest tornado to Kane County was in Plattville, which you can see on the map above. That one was spotted by radar and people at around 1:48 p.m. Monday, May 27.

Another was reported in Paw Paw to our west at around 4:33 p.m. Monday, May 27. That’s highlighted on the NWS map below.

More On The Way

After a break for most of the area today, rain chances increase again from this evening into Wednesday morning.

Some of the showers and thunderstorms overnight could produce locally heavy rain which could lead to flooding, especially in areas where the ground is already saturated from recent heavy rainfall.

A break in the pattern appears to arrive Thursday afternoon or evening. Friday presently looks dry, but there is another chance of showers on Saturday though likely not with the heavy rain amounts we have been seeing.
