I have always thought the area just south of the city has a lot of severe weather. I read somewhere that that is an actual thing. Cool weather from the lake collides with warm weather coming from the south. But I can't find the article now.

I grew up in Hyde Park and now live in Beverly and just from my experience, this seems true (about more severe weather further south). In particular, I don't remember feeling like we had to be careful about going outside during wind storms when I lived in Hyde Park, but now when there's a wind advisory, I take it seriously. HOWEVER, approximately 20 years went by between living in HP and living in Beverly, so it could also be an overall weather-pattern shift.

"Lake Michigan influences the climate of Chicago and most of northeastern Illinois. The large thermal mass of the lake tends to moderate temperatures, causing cooler summers and warmer winters. One of the major benefits is cool lake breezes that provide some relief from summer heat. The lake also tends to increase cloudiness in the area and suppress summer precipitation. "

Maybe?

Maybe?

Definitely. You can see that entire process here. It would be easy to assume that if the conditions are similar as a storm system passes, at the very least the lakes will disrupt the storms if not completely dissolve them.

Old thread, but I asked myself the same question 25 years ago after the Plainfield F5. That deadly storm paralleled the shoreline, 50 miles inland.

The above satellite shows lake breeze storms developing, a localized phenomenon that rarely generates severe weather. However, thunderstorms act in somewhat the same fashion. As they approach cooler waters, updrafts draw in cooler air temps at low levels. This slows the heat exchange process necessary to maintain strength, similar to hurricanes needing warm water.

Ehhh... You don't know "cloudiness" until you've lived in Cleveland. I'd forgotten how gloomy winters are here. Chicago is like sunny California in comparison.

The top half will break off and head upwards towards Wisconsin and mid-northern Michigan, the bottom half will head just southeast of us. I've noticed this happens at least half of the time a storm system heads in our direction; storms frequently circumvent the city.

Take today for example: the weather told us we had a 60%-90% chance of storms from 4-7pm. Low and behold the storm seems to be breaking up and we've only gotten light rain thus far. I know it seems trivial, but am I the only one to notice this pattern? I feel like Southern Wisconsin and Western Illinois get all the storms
The storms are scared they'll be shot.
