...Heightened Fire Danger This Afternoon...

Strong southwest to west-northwest winds, low relative
humidities, and unseasonably mild temperatures will result in a
heightened fire danger this afternoon over northern Illinois and
northwest Indiana, especially south 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.

particularly in open rural areas. Be prepared for variable and
slippery road conditions if traveling today. Periods of light snow
are also expected today which could lead to minor visibility
reductions and an additional dusting on roadways.
