CHICAGO (WLS) — After several days of unseasonably warm temperatures, Chicago-area residents should expect a massive cold snap Thursday as families prepare for Halloween trick-or-treating.

There is also a threat of isolated severe thunderstorms in the early hours of Thursday for parts of the area.

While the morning showers will move away before trick time, a cold front is expected to arrive later in the day.

Temperatures will be in the 60s by 1 p.m. before dropping into the 40s after sunset, Mowry said.

FULL FORECAST | Chicago Weather: Still windy and unseasonably warm, rain late Wednesday

A wind advisory is in effect until 10 p.m. Thursday, the National Weather Service announced. Wind gusts could reach 50 mph, Mowry said.

People in the Chicago area enjoyed the warm weather, which felt like a little rebirth of summer.

From driving ranges to bike lanes, ABC7 saw people trying to make the most of this unseasonable heat Wednesday.

It was a hat-less, glove-less day at Burnham Harbor for Megan Thomas as she enjoyed a bike ride along Chicago’s lakefront.

“We’re coming up on Halloween and a few years ago it was snowing and I’m riding my bike in shorts, so I can’t complain though,” Thomas said.

For the next day, autumn in the city was more like a summer day. Tuesday’s high of 82 broke a record.

“Can’t complain,” said golfer John Anderson. “I like it like this, not too hot, cool. I like weather like this. I can deal with that every day.”

The pleasant weather drove many golfers to the Jackson Park Golf Range.

“We’re stealing days right into October, November right now,” golfer Richard Tulloch said. “We’ll take them all while we can … we’ll chase the leaves and tell stories and enjoy hitting balls.”

Despite the mild temperatures, it’s that time again when all boats, except those with late departure permits, must be out of Chicago harbors by October 31st.

Tom Houston and his crew have six more boats to dock at the 134th Indiana Marine Center.

“It’s usually a lot colder, but the wind is crazy today, so we can’t do much more today,” Houston said. “This was pretty hard to get on the trailer.”

While most enjoyed the unseasonably warm weather knowing it couldn’t last, Adam Bilter decided to make the most of it on a friend’s boat on the lake as he waits for the reality of fall to finally set in and then winter.

“I already have the sweaters and gloves off and I’m ready to go,” Bilter said. “I’m ready.”
