No problems for the morning

rapidly this afternoon as strong winds and snow move in, along with
Rain will change over to snow during the afternoon, with

higher totals just to our west and north. Strong west to northwest

[Text from National Weather Service,
Rain will change over to snow across the west and
northwest part of the state later Thursday morning as the strong
storm tracks across central Illinois.
The changeover to snow farther
east will occur Thursday afternoon as the center of the low shifts
to near Chicago. Once that happens, winds will increase from a west
to northwest direction with speeds of 35 to 45 mph and occasional
gusts around 55 mph. This will cause considerable blowing and
drifting snow in areas along and west of the Illinois River Thursday
afternoon, with near blizzard conditions in a few locations.
Farther east, the transition to
snow will occur from west to east Thursday afternoon and evening.
Areas roughly along and west of a Bloomington-to-Springfield line
may see 2 to 3 inches late this afternoon into this evening, with
the blowing and drifting concern setting in for the drive home from
work or school.
Over east-central and southeast
Illinois, snow accumulations for the most part will be an inch or
less, but the strong winds will cause whatever snow that does fall
to blow around and cause slippery roads Thursday evening.
