Strong to severe storms with chances for hail, heavy downpours and even tornadoes were once again in the Chicago forecast Friday, with more flooding possible and a “drastic” change in temperature on the way.
“Here we go again,” NBC 5 Storm Team Meteorologist Alicia Roman said, of the severe weather risk, which starts later in the day.
Early Friday morning, conditions were dry but foggy, with low visibility and dense fog advisory in effect for the entire Chicago area until 10 a.m.
“Love visibility could make dangerous driving conditions,” the National Weather Service warned, some some parts seeing visibility at a quarter of a mile or less. “If driving, slow down, use your headlines and leave plenty of distance ahead of you.”
Photos and video captured early Friday morning by NBC 5 photographer George Mycyk showed the blurry conditions, with fog hovering over Lake Shore Drive.
Partly-to-mostly sunny skies will move in as the fog gradually lifts, Roman said, with hours of dry time and temperatures in the 70s and even 80s.
About 5 p.m. is when showers and storms will begin to develop, Roman said, starting to the west.
According to Roman, showers are expected to start to the west as early as 5 or 6 p.m.
Between 8 and 10 p.m., storms will near Chicago, the lakefront and the south suburbs, Roman said. By about midnight, storm intensity will taper as the system moves east into northwest Indiana.
‘Enhanced’ risk of severe weather
Nearly all of northeastern Illinois will be at an “enhanced” risk of severe weather Friday night, which ranks as level three of five.
Damaging winds as high as 60 mph, large hail, and heavy rain were all possible, Roman said.

Flooding problems
More flooding from Friday’s rain will be a big concern, Roman said. River flood warnings were already in effect across the Chicago area, with the NWS saying many rivers were forecast to crest into a minor or moderate flood stage from recent rainfall.
“Additional rainfall this evening may lead to further river rises and/or delayed crests through the weekend and into next week,” the NWS warned, with Rock, Fox, Des Plaines and Kankakee Rivers being the most vulnerable river basins.
Temperature drop
As the active weather pattern winds down, temperatures will “drastically drop,” Roman said, with cooler and drier conditions moving in over the weekend.
“Areas of frost and locally sub-freezing temperatures will be possible Saturday and Sunday nights,” the NWS said.
