The National Weather Service says Evanston could get as much as four to seven inches of snow on Friday.
The storm is expected to begin after the morning rush hour and may be heavy at times with about three to five inches arriving by nightfall.
Temperatures will be warmer than today with a high near 24.
Friday evening snow will taper off, ending around midnight with one to two more inches of snow expected.
Evanston's Streets and Sanitation Superintendent James Maiworm says the evening rush hour is likely to be affected by the storm.
He says crews will concentrate on snow routes and primary roads through rush hour and then work on residential streets during the evening.
He says the snow is expected to be very light with low mositure content, which will help in the cleanup process.
Depending on the timing and accumulation of snow, Maiworm says, parking restrictions may be needed and the residential and condominium recycling collection may be delayed to ensure adequate snow removal equipment is available.
