Special Weather Statement issued February 5 at 3:27PM CST by NWS Chicago IL
Feb 5, 3:27 PM
→ Feb 5, 9:00 PM
A fast moving weather system will produce a short 3 to 5 hour period
of accumulating snow late tonight into early Friday morning.
While significant snowfall amounts are not expected, a burst of
snow, with rates up to 1 inch per hour, could result in a period
of slick travel due to snow covered roads early Friday morning.
Accordingly, motorists are urged to plan for extra time to reach
their destination Friday morning.
