Wintry weather is to follow the recent
mild temperatures. The National Weather Service in Lincoln has
issued a winter weather advisory for snow. The advisory is in effect
from 10 p.m. Tuesday to 1 p.m. Wednesday for the counties of Knox,
Stark, Peoria, Marshall, Woodford, Fulton, Tazewell, McLean,
Schuyler, Mason, Logan, DeWitt, Piatt, Champaign, Vermilion, Cass,
Menard, Scott, Morgan, Sangamon and Macon, including the cities of
Galesburg, Peoria, Bloomington, Normal, Havana, Lincoln, Champaign,
Urbana, Danville, Jacksonville, Springfield and Decatur.
Rain will overspread much of central Illinois on Tuesday
evening, then change to snow in the late evening from Rushville to
Bloomington northward. The change to snow will likely occur shortly
after midnight around Springfield and Jacksonville, then between
midnight and 3 a.m. for areas from Decatur east to Danville. The
snow will end from west to east Wednesday morning.
Accumulations: Snow accumulations of 3 to 5 inches are likely
from Rushville to Danville northward. Locally higher amounts are
possible, especially from Bloomington north and east. Closer to the
Interstate 72 corridor, snow totals of 2 to 3 inches are likely. The
heaviest snow is most likely between midnight and sunrise.
Wind: Northerly winds will increase overnight and range from
20 to 30 mph. Some gusts to around 40 mph are possible near the I-57
corridor. The windy conditions will continue into Wednesday morning.
Impacts: Roads will quickly become slushy as the snow
accumulates. As temperatures fall into the 20s overnight, the slush
will begin to freeze as well, causing icy travel conditions.
Visibility will be significantly reduced in the heavier snow bands.
The wet snow is expected to limit the amount of blowing and drifting
to a relative minimum, although areas near Champaign and Danville
are more likely to see some blowing snow due to the higher wind
speeds in that area.

Precautionary, preparedness actions: A winter weather
advisory for snow means that periods of snow will cause primarily
travel difficulties. Be prepared for snow-covered roads and limited
visibilities and use caution while driving.
