Special Weather Statement issued January 28 at 3:46AM CST by NWS Chicago IL

Strong southwest winds, low relative humidities, and unseasonably
mild temperatures will result in a heightened fire danger this
afternoon over northern Illinois, especially north of I-80.
Quicker drying and dormant fuels like brush and grass will be
particularly susceptible to ignition with strong winds likely
leading to the rapid spread of any fires that do occur.

Use caution with the disposal of smoking materials and consider
postponing any outdoor burns to a different day.
