Alicia Roman has the latest forecast update for the Chicago area.
An air quality alert has been issued by the Illinois Environmental Protection Agency Monday, with air quality expected to be at levels that are "unhealthy for sensitive groups."
The Air Pollution Action Day was declared by the IEPA for several Chicago-area counties for Monday Monday, citing "elevated ground-level ozone," according to a press release from the IEPA. A similar air quality alert was also issued Sunday.
The Action Day includes Cook, DuPage, Kane, Kendall, Grundy, Lake, McHenry and Will counties, the release said. It will remain in effect until Midnight.
In Illinois, an Air Pollution Action Day is issued when air quality is forecasted to be at or above the Orange or “Unhealthy/Sensitive Groups” category for two or more consecutive days.
As of 6 a.m., Monday, according to AirNow, the Chicago area's Air Quality Index measured at "Moderate," which ranks as level two on a six level scale. As the day continues, the AQI is expected to reach level three, "Unhealthy for Sensitive Groups."
The AQI is measured based on five major air pollutants, including ground-level ozone, particle pollution and others. Ozone levels tend to be elevated during spells of hot weather, and more particle pollution occurs when residents use air conditioning units in their homes and businesses, officials say.

Those with pulmonary illnesses and other risk factors such as asthma, children and teens, older adults, and individuals who are routinely active outdoors for six or more hours per day should reduce exposure outdoors during the alert, according to officials.
Those who worry about being affected should look out for the following symptoms: wheezing, coughing, a fast
heartbeat, fatigue, chest pain and shortness of breath. If symptoms worsen, you should call your doctor or 911.

properly tuned. - Conserve energy to reduce energy demands.
- Use environmentally friendly household and cleaning products.

In addition to the air quality alert, Monday is expected to be a muggy and hot day, continuing a long stretch of 90-degree temperatures and even higher heat indices, the NBC 5 storm Team said.

"Every single day this week will feature temperatures in the 90s and high humidity as well," NBC 5 Meteorologist Alicia Roman said.
The forecast Monday across the Chicago area calls for a high temperature of 96 degrees -- which could tie the record for the Chicago area, set in 1957, Roman said.
"No lakefront cooling today," Roman stressed.
Additionally, humidity levels Monday will straddle the line between "muggy" and "extreme," Roman added, noting dewpoint temperatures in the 60s and 70s.
"Hydrate, hydrate, hydrate," Roman warned.

Monday could also see isolated afternoon storms as the day heats up, Roman said.
"There's a low-end chance for a storm with the heating of the day," Roman said. "Not everyone will see it."
Locations that do see storms could see quick, heavy downpours, Roman said.
Temperatures in 90s and isolated storm chances will continue through the rest of the week, Roman said, with relief not arriving until the weekend as a cold front passes through.
At that time, more showers and storm chances are expected, Roman said, with temperatures dipping back down into the mid 80s Sunday.
