Warm Now, Storms Coming

Severe storms could produce half dollar-sized hail

Memorial Day temperatures could break record highs for a second day ahead of potentially severe thunderstorms Monday evening.

Sunday temperatures reached 97 degrees, making it the earliest date in the year when temps were that high. The last time Chicago was this hot this early was May 31, 1934. 

Another warm day could push past a record 93 degrees. By lunchtime, temps could hit 89, according to NBC Chicago meteorologist Alicia Roman.

Scattered showers are expected to move in Monday afternoon and evening with some strong thunderstorms expected. The National Weather Service warns severe storms could produce half dollar-sized hail, damaging winds reaching 60 mph and heavy rain.

There's a 40 percent chance of showers and thunderstorms mainly between 7 p.m. and 1 a.m. Until then conditions remain mostly sunny and breezy.

A strong southwest wind combines with unseasonably hot and dry air could increase the threat of fires, according to the National Weather Service. Those spending time outside are urged to exercise extreme caution with any flames.
