A strong cold front will push across the
southeast half of Illinois through late Friday afternoon, becoming
stationary south of the Ohio River by Saturday morning. Waves of low
pressure will move along this front and will produce significant amounts
of precipitation across central Illinois through the weekend. Although cold air will be found at the surface, much warmer
conditions aloft will result in the precipitation being primarily in
the form of freezing rain. Significant ice accumulations will be
likely from this system, with the thickest ice in areas from
Springfield southwestward.
Travel conditions this weekend will be extremely hazardous across
much of the mid-Mississippi Valley.
The following ice storm warning is in effect from 9 p.m.
Friday to 6 a.m. Monday for the counties of McLean, Logan, Cass,
Menard, Scott, Morgan and Sangamon, including the cities of
Bloomington, Normal, Lincoln, Jacksonville and Springfield:
Scattered light rain is expected to change over to freezing rain
Friday evening across central Illinois. Accumulations of ice up to a
tenth of an inch will be possible by late Saturday morning. Although
the precipitation is expected to taper off for a while on Saturday,
more freezing rain is expected to develop Saturday night, continuing
into late Sunday night, before changing to snow. Total ice
accumulations of a quarter- to half-inch of ice are expected across
the area, with even higher amounts farther southwest toward Saint
Louis. Areas north of Interstate 72 may see a light accumulation of
snow on top of the ice.
Many trees in central Illinois were weakened by the ice storm at
the beginning of December and may be more susceptible than usual to
damage from this ice accumulation.
An ice storm warning means severe winter weather conditions are
expected or occurring. Significant amounts of ice accumulation will
make travel dangerous or impossible. Travel is strongly discouraged.
Commerce will likely be severely affected. If you must travel, keep
an extra flashlight, food and water in your vehicle in case of an
emergency. Ice accumulations and winds will likely lead to snapped
power lines and falling tree branches that add to the danger.
The following ice storm warning is in effect until 6 a.m.
Monday for the counties of Knox, Stark, Peoria, Marshall, Woodford,
Fulton, Tazewell, Schuyler and Mason, including the cities of
Galesburg, Peoria and Havana:
Precipitation that occurs will mainly be in the form of freezing
rain. Accumulations of ice up to a tenth of an inch will be possible
by Saturday morning. Although the precipitation is expected to taper
off for a while on Saturday, more freezing rain is expected to
develop Saturday night, continuing into Sunday night, before
changing to snow. Total ice accumulations around a quarter-inch are
expected across the area, with a few inches of snow late Sunday
night and Monday on top of the ice.

Arctic air will continue to push into the state in the wake of a strong
cold front. While precipitation with this front will mainly be in the

after midnight toward the I-57 corridor.

Saturday, more freezing rain is expected to develop Saturday night,
