Increased Chance Of Storms Friday Night, Hot Temps Throughout The Weekend

CHICAGO (CBS) -- While storms are expected throughout the area, soaring temperatures are on the horizon for the weekend.

A short wave over Minnesota will sink through the area, increasing the chance of thunderstorms after dark. Storms will be in the overnight forecast through Saturday morning and isolated storms will be possible for the rest of the day Saturday.

The jet stream allows our region to heat up for a steamy weekend. But with the wind flow so light, a light onshore wind will keep temps cooler along the lakefront both Saturday and Sunday.

The Pride Parade on Sunday will be quite warm with partly sunny skies.

CBS 2 meteorologist Mary Kay Kleist will have more on the weather tonight at 5 p.m. and 6 p.m. Here's a look at the extended forecast:

Friday night: Storm threat. Some strong with high winds and hail. Low  of 72.

Saturday: A 20% chance for storms, high of 90 with a heat index of 95 degrees. Northeast wind 5 mph so temperatures lakeside should hold be in the 70s.

Sunday: Partly sunny with a high of 90. It'll be closer to 80 degrees lakeside.

Monday: Scattered storms with a high of 90.

Tuesday: Scattered storms. Expect a high of 87.

Wednesday: Scattered storms with an expected high of 86.

Thursday July 4th: More scattered storms with a high of 85.
