[December 13, 2013]  A mix of wintry weather is headed for central and southeast Illinois, according to a winter weather message Friday morning from the National Weather Service in Lincoln.

A winter weather advisory is in effect from 3 p.m. Friday to 6 a.m. Saturday for the counties of Knox, Stark, Peoria, Marshall, Woodford, Fulton, Tazewell, McLean, Schuyler, Mason, Logan, DeWitt, Piatt, Cass, Menard, Scott, Morgan, Sangamon, Christian, Macon, Moultrie and Shelby, including the cities of Galesburg, Peoria, Bloomington, Normal, Havana, Lincoln, Jacksonville, Springfield, Taylorville, Decatur and Shelbyville.

Timing: Precipitation is expected to begin moving into areas around Jacksonville early Friday afternoon, spreading northeast to Bloomington and Peoria by late afternoon. This will be a mixture of rain, sleet and snow, with a period of only rain around Springfield and Jacksonville during the afternoon. The precipitation will quickly turn to all snow by early evening and persist through the night before tapering off early Saturday. The heaviest snow will be during the evening.

Accumulations: Total snow accumulation of 4 to 5 inches will be common, with amounts near 6 inches along and north of Interstate 72. Some light sleet accumulation is possible early on in the event.

Wind: Southeast winds will turn northeast overnight, but with speeds less than 10 mph. Blowing and drifting snow is not expected to be a factor.
