...Accumulating snow event expected this weekend...
A winter weather system is expected to develop in the Southern Plains this weekend and lift northeast into the Tennessee Valley. As the system develops...a mix of rain and snow will move into central Illinois Saturday evening. During the late evening the precipitation will change over to all snow. The snow will become moderate during the overnight hours...with 2 to 3 inches of accumulation possible by Sunday morning...mainly north of Interstate 70. Snow will continue across central and southeast Illinois during the day Sunday...with an additional 2 to 3 inches possible through Sunday afternoon. As the system lifts further east of the area Sunday night...the snow will taper off and only around one half inch of additional accumulation is expected at this time. Total snowfall from Saturday night through Sunday night could range from 5 to 6 inches. Current thinking is that the axis of heaviest snowfall will occur somewhere along a Jacksonville to Danville line.
This system is still a couple of days away and there still remains some uncertainty as to the track of this system and the amount of snowfall possible. Therefore...changes in the amount and location of the heaviest snowfall will likely change between now and the time the snow arrives Saturday night. So...stay tuned for later updates to this winter weather situation.
