The Chicago area will see one more mild day before temperatures come tumbling down, the NBC 5 Storm Team said, with the potential for flurries on Halloween.
"We're definitely going to have to bundle up as we go into Halloween," NBC 5 Meteorologist Alicia Roman said. "You may have to put that jacket on, or your costume on top of your jacket.
Friday, temperatures will remain warm and breezy, with wind gusts up to 20 miles per hour and high temperatures in the upper 60s to low 70s. Additionally, scattered, widespread showers are expected at times for much of the area.
According to Roman, some isolated thundershowers or storms could pop-up around 4 p.m. and through the evening hours. Overnight, the showers are expected to come to an end, although lingering showers east of I-55 may remain, the National Weather Service said.
As of 5:30 a.m., the current temperature in some spots was 67 degrees, which is "well above the average high for this time of year," Roman said.
According to Roman, temperatures will top out Friday afternoon around 73 degrees.

"Sunday will be a chilly rain, unfortunately," Roman said, with highs in the 40s.
According to the NBC 5 Storm Team, Monday will remain dry, with temperatures in the low 40s.
Temperatures Tuesday will also remain in low 40s. And, Chicago could see the first flakes and flurries of the season on Halloween, the NBC 5 Storm Team added.
"We could see a quick moving disturbance Tuesday bringing some light snow showers or flurries in the forecast for Halloween," Roman said.
Snow on Halloween isn't unusual. According to the NBC 5 Storm Team, the average first trace of snow for the Chicago area -- which is defined as less than a tenth of an inch -- typically arrives Oct. 31. But the average first measurable snowfall, which is defined as a tenth of an inch or more, is Nov. 18.
For those looking for at least an inch of snow or more, the average date for that snowfall is Dec. 7, the Storm Team said.
