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. $$ WSL
