(5:15PM - 1/31/19) A fast moving clipper system has spread snow across much of Northern and portions of Central Illinois this afternoon. This snow is expected to continue through this evening, before ending from west to east tonight. Periods of moderate to heavy snow and 1" per hour snowfall rates are likely at times. Final snowfall totals of 1-3" will be widespread across much Northern and portions of Central Illinois. There will be an axis of heavier amounts of 3-6" near and just south of I-80. It should be stressed though, that most areas in that axis will end up on the lower end of the 3-6" range.
Further south, a period of mixed precip is still possible across Southern Illinois tonight into tomorrow morning.
