Showers move in Tuesday evening, warm and humid weekend ahead

Data pix.

A band of showers and a few thunderstorms associated with an upper-level disturbance are tracking southeast out of Wisconsin across McHenry and Lake Counties, and into Cook County/Chicago later this afternoon/early evening.

If the showers/t-storms hold together long enough they could cross the southernmost portion of Lake Michigan into NW Indiana. The strongest storms could produce brief heavy rainfall, lightning, gusty winds and even the possibility of small hail.
