The largest snowfall of the season is on the way to Springfield and central Illinois.
Rain was expected to move in Friday afternoon before transitioning to snow.
The National Weather Service has issued a winter weather advisory beginning at 6 p.m. and continuing until noon Saturday with two to four inches of snow accumulation possible, according to meteorologist Kirk Huettl. The advisory includes Sangamon, Logan and Christian counties.
The heaviest snowfall is expected between 6 and 8 p.m. Friday, Huettl said, with the greatest accumulation to the west. Up to five inches of snow could fall near Jacksonville.
Huettl warned that travel may become hazardous into Saturday morning especially in rural areas where snow could blow and drift.
How will the city clear streets?
Springfield Public Works Department crews have pretreated bridges and overpasses in preparation for the weather, director Nate Bottom said Friday. The department will monitor conditions throughout the day and will extend the early crew's workday to salt and plow roads as needed. The night crew will arrive about 7 p.m. to continue the work overnight.
Bottom said crews will clear major roadways first and then move to secondary streets and could even get to some subdivisions.
Crews are expected to spread 1,000 tons of salt through Saturday. Bottom added the city orders about 6,000 tons of salt annually.
What will the temperatures be?
Temperatures are forecast to stay below freezing overnight with a low of 25 degrees and high of 28 degrees Saturday.
