The heat index is expected to rise in rural counties from Lee County to Iroquois County and west. Wet, mature corn crops are expected to contribute to high humidity in the area and contribute to Heat Index values of 95 to 105°F.
The heat index in the northwest suburbs is expected to reach as high as 99°F.
Rapid thunderstorm growth is possible, but the most severe weather is expected south and west of north and northwest suburbs of Chicago.
