CHICAGO (CBS) — Unstable, and possibly severe weather is in the cards for Friday and the start of the Memorial Day weekend.

CBS 2’s Megan Glaros says the Chicago area is under a slight risk of severe storms on Friday evening. This comes after a wave of rain and lightning swept through in the early morning. Another wave could arrive on Friday afternoon.

The main threats will be wind, hail and heavy rain.

The National Weather Service issued a Tornado Watch for counties just south of the CBS 2’s viewing area.

Showers and storms are possible on Saturday and Sunday, but Glaros says the weekend won’t be a total washout.

Temperatures will reach the 70s and 80s throughout Chicagoland.
