Accumulating wet snow continues overnight – will end from the west early Monday morning

Update 10PM CDT…

At 10PM the band of heaviest snow has moved north of the Interstate-80 corridor (see darker embedded area in the snow band shown on the radar map below) where 3 to 5-inches-plus has fallen. The wet snow should continue well past midnight, gradually ending from the west by early Monday morning. Additional accumulations of an inch or two may occur in the heavier snow areas, while another inch or less will occur elsewhere. Obviously the storm system has been more intense than anticipated (at least in some portions of our area), but ending times for the snow remain about the same. Again if traveling this evening and overnight, be aware you may run across slushy and slick conditions.

Here is a list of reports as of 10PM CDT…(inches)

Joliet (Will CO)…4.2
Peotone (Will CO)…3.0

Update 7PM CDT…

By late afternoon a band of 2 to 3-inch snowfall has occurred along the Interstate-80 corridor in Illinois with amounts between a half-inch and inch elsewhere. Wet snow will continue to fall overnight, much of it melting on contact, so the range of snowfall totals will probably continue to run in the 1 to 3-inch range. Where most intense snow occurs, pavement will become slushy and slick, so be cautious if on the road.

Following are some reports received by 6PM…(inches)

Carbon Hill (Will CO)…3.5
Joliet (Will CO)…2.7
Beecher (Will CO)…2.6
Plainfield (Kendall CO)…2.5
Oak Forest (Cook CO)…1.8
Midway (Cook CO)…1.1
Charsworth (Livingston CO)…1.0
Romeoville (Will CO)…1.0
St. Charles (Kane CO)…0.8
Arlington Hts (Cook CO)…0.8
O’Hare (Cook CO)…0.4


A wet snow (mixed with a little light rain at times) will spread north and east across the Chicago area this afternoon – continuing well into the overnight hours before ending from the west early Monday morning.

Much of the snow will melt upon contact, but still accumulate 1 to possibly 3-inches primarily during the evening hours on grassy surfaces.  Because temperatures will be hovering in the lower 30s – streets, highways and sidewalks will be mainly wet, but depending upon variations in snowfall intensity may become slushy and slick at least in spots.

It looks like the snow will occur from the central portions of Illinois and Indiana north, so travel into or from those areas could become somewhat hazardous. Most of the snow will melt off Monday, as temperatures warm back well into the 40s.

Progress of the snow can be followed on the Regional Weather Radar Map below. Reduced visibility on the the visibility map will indicate areas of greater snow intensity.
