CHICAGO (CBS) — As heat and humidity continue to build, there is a growing chance of a thunderstorm on Saturday afternoon.

Those storms could begin by 2 p.m .and scatter about through sunset. The Storm Prediction Center has our area with a “marginal” risk for severe weather. That’s a one on a scale 1 to 5.

This system does not have a lot of moisture to work with.

Clearing will take place Sunday. Then a long stretch of dry and quiet weather through next week.
