Weather Service: Winter Storm Warning Through Weekend
January 4, 2014 by Jerry Howard
The National Weather Service Chicago Office has an “urgent winter weather message” for the Greater Chicago area about weather through the weekend.
It has a winter storm warning in effect through 6 p.m. tomorrow for Illinois’ counties in the metropolitan Chicago area, extending that storm warning time frame through midnight Sunday in some parts of Illinois and northwest Indiana.
Dupage, Cook, La Salle, Kendall, Grundy and Will counties are in the winter storm warning in effect until 6 p.m. tomorrow, where the National Weather Service says snow will develop this afternoon and continue into tomorrow.
The Weather Service expects moderate to heavy snow that result in 5 to 10 inches of new snow accumulation with hazardous travel conditions and likely delays at O`Hare and Midway airports.
It also expects northwest winds that could cause blowing and drifting snow with reduced visibility.
The Weather Service’s extended winter storm warning includes Kankakee, Livingston, Iroquois and Ford counties in Illinois and Indiana counties of Lake, Porter, Newton, Jasper and Benton. That winter storm warning is in effect from 6 p.m. (CST) tonight through midnight tomorrow.
The Weather Service expects snow to develop across the area by early this evening with snowfall rates that should increase later tonight into tomorrow. It says the potential for periods of heavy snow could bring 6 to 10 inches of new snow accumulation, leading to hazardous travel conditions.
Again, it predicts brisk northwest winds that could result in blowing and drifting snow with reduced visibility, making travel “very hazardous or impossible.”
A winter storm warning means significant amounts of snow are expected or occurring, with strong winds possible as well.
