...Burst of accumulating snow this evening...

A band of snow will sweep move across northern Illinois this
evening. Though the snow may only last for two to three hours at
any given location, snowfall rates could reach near 1 inch per
hour, resulting in quick accumulations on roadways. Sharply
reduced visibility under one half mile and winds gusting as high
as 30 mph will further exacerbate the hazardous travel conditions.
Prepare for rapidly changing conditions if traveling this
evening. The snow is expected to taper off later this evening.

...Risk for river ice formation and ice jams will continue into next
week...

Favorable conditions for river ice development and possible ice jams
will exist through today and then return early next week, impacting
the Rock, Fox, Des Plaines, and Kankakee river basins.

Very cold temperatures, favorable for rapid formation of river ice
on most areas rivers, will continue through today. After a brief
warm-up on Saturday, an additional period of very cold weather is
expected to arrive early next week. Area river gauges indicate
likely ice effects and a few minor ice jams, although no flooding
appears imminent at this time. New and worsening river ice cover
remains possible into tomorrow, which may lead to rises on area
rivers with little warning. A multi-day period of very cold
temperatures next week will likely bring another period of favorable
conditions for heavy river ice and ice jams.

No additional updates to this product are scheduled at this time,
but may be required prior to early next week if temperature
forecasts continue to indicate favorable river ice conditions.
