WGN-TV Chief Meteorologist Demetrius Ivory joins Lisa Dent to give this week’s weather forecast and answer all weather-related questions from The Lisa Dent Show. Demetrius starts out by updating listeners in real time about the flash flood warning in effect at the time for both Cook and Will Counties and a tornado warning that had been in effect earlier. Later, he updates listeners on the latest forecast for Tropical Storm Helene, expected to become a major hurricane by the time it makes landfall in Florida, likely Thursday night, and then works its way deep into the country, potentially creating significant rainfall in the Chicago area on Sunday.
