Timing: Snow is expected to begin by late
Tuesday morning near Jacksonville and Rushville and may extend in a
narrow corridor as far east as Bloomington and Champaign by midday.
The snow will become widespread during the afternoon across all of
central Illinois and continue much of the night before diminishing
Wednesday morning. Blowing snow will begin occurring by late Tuesday
evening and continue into Wednesday morning.
Accumulations: Two to 4 inches of snow will be likely by
sunset Tuesday. By the time the snow ends Wednesday morning, a total
of 6 to 7 inches will accumulate in much of central Illinois, with
locally higher amounts along a line from Rushville to Danville. In
areas north and northwest of Peoria, storm totals of 5 to 6 inches
will be more common.
Wind: Northeast winds of 10 to 20 mph will become northerly
[to top of second column]
Visibilities: Heavier bands of snow will reduce visibility to
under a half-mile at times Tuesday afternoon and Tuesday night. In
addition, blowing snow will reduce visibilities at times Tuesday
night through Wednesday morning.
Impacts: Road conditions will rapidly deteriorate Tuesday
afternoon and remain poor through Tuesday night. Areas of blowing
snow Tuesday night will reduce visibilities and contribute to the
hazardous road conditions.
Precautionary, preparedness actions: A winter storm warning
for heavy snow means severe winter weather conditions are expected
or occurring. Significant amounts of snow are forecast that will
make travel dangerous. If you must travel, keep an extra flashlight,
food and water in your vehicle in case of an emergency.
