Autumn creeps in as Sunday storms are expected

As temperatures continue to drop, fall is approaching in Chicago. A warm weekend should offer a taste of summer, although storms expected on Sunday could derail plans.

Temperatures in the mid-70s are expected on Friday, the National Weather Service said. Nighttime temperatures could dip into the mid-50s.

The National Weather Service has issued a warning of hazardous swimming conditions for southern Lake Michigan beaches. Waves as high as six feet could create life-threatening currents and dangerous sailing conditions near shore Friday, the service said.

Warmer weather is expected Saturday, when temperatures hit the 80s. But rain and possible thunderstorms could roll in Sunday afternoon, National Weather Service meteorologist Kevin Doom said.

“I’ll just do all your outdoor plans for Saturday,” he said.

Sunrise has been almost thirty minutes late since the beginning of the month, an illuminating sign of this too short-lived end of the season. The meteorologist said the weather also rocked the fall.

The city has been experiencing closer to normal temperatures lately, although the weather is still slightly warmer than it usually is at this time of year, he said.

“Temperatures have been on a downward trend,” Doom said. “We are slowly starting to transition into autumnal weather.”

Temperatures are expected to remain in the mid-80s through next week, with a high chance of rain and persistent thunderstorms through Monday.
