Increasing confidence in a fairly narrow swath of significant snow (possibly 6"+) Fri. night into Sat. Currently favored from near Sterling IL to Rensselaer IN. Sharp cutoff is likely either side of the heaviest snow & heaviest snow swath could shift south or north. #ilwx #inwx pic.twitter.com/7IEFdl839g

Spring is here but has it sprung? Not exactly in northern IL & northwest IN, although some sun this p.m. and milder temps Thu & Fri.
— NWS Chicago (@NWSChicago) March 21, 2018
Increasing chance for late season wintry precip later Fri night & Sat, especially southern & western locales. https://t.co/hvAEYCJelM #ilwx #inwx pic.twitter.com/ddKpo1UKk4
