Update 9:30PM CST…
Snow will end from west to east across northeast Illinois by midnight and northwest Indiana shortly thereafter. Because temperatures will be in single digits above and a little below zero overnight, Plowed highways will still be slick in spots with many secondary roads, streets and sidewalks/parking lots snow-covered and slippery. Travel will continue to be slow and those outside need to continue to take necessary precautions.
With snow ending and gradually clearing skies during the predawn hours, wind chills will run in the -10 to -18-degree range by sunrise Tuesday. The cold temperatures will continue with increasing cloudiness during the day – the next accumulating snow possible Tuesday night.
Temperatures Monday morning dropped well below zero with wind chills in the dangerous -15 to -20-degree range across northeast Illinois into northwest Indiana.
If outside for any length of time, make sure exposed skin (face/hands) are protected (see latest temperatures/wind chills on maps below) – especially properly prepare children waiting on school buses or taking long walks to school.
This afternoon accumulating snow is forecast to spread from west to east across our area – probably beginning in westernmost portions along the Interstate-39 corridor and the Fox River Valley by early afternoon and reaching Chicago and northwest Indiana by mid to late afternoon.
A Winter Weather Advisory for 3 to 6-inches of snow area-wide is in effect with snowfall rates looking to peak around the late afternoon/early evening commute. Anticipate very slow dangerous travel conditions with snow-covered slick roads later this afternoon and evening. Below is the latest Rapid precision Mesoscale (RAP) modeling forecast projection of the snow development/spread across our area.
More than 400 flights have proactively been cancelled at Chicago’s O’Hare Airport, and more than 20 flights at Midway Airport.
