CHICAGO (CBS) – We’re in for a mild night Saturday ahead of a warmer day on Sunday.

Overnight will see temperatures drop into the upper 60s or low 70s.

Temperatures on Sunday will be even warmer than Saturday, with a high expected to be about 90.

Sunday will be a dry day for the most part, but an isolated storm or shower is possible.

Temperatures won’t cool down as much at night on Sunday, because of higher humidity during the day.

A few storms could move in late Sunday night or early Monday, but we’ll likely see a round of stronger storms Monday afternoon, especially because it will be so warm, with temperatures reaching the upper 80s.

Daytime temperatures eventually will fall back to the low 80s later in the week, with chances of isolated storms through the end of the week.
