Lake County IL Winter Storm Watch

Emergency Management Partner Update
Lake County and surrounding areas are facing the first significant storm event for the winter season, with rain beginning as early as this evening, then winds increasing winds, falling temperatures, and rain changing to snow on Thursday. The National Weather Service (NWS) has expanded the Winter Storm Watch to include Lake County, and that watch will be in effect from 6:00 p.m. on Thursday through 6:00 a.m. on Friday.
Lake County Emergency Management is continuing to monitor this evolving situation, and remains in contact with our partners at the National Weather Service, Lake County SKYWARN, and the Lake County Division of Transportation. While the overall forecast for this storm has been consistent for several days, slight changes in the timing or track of the low pressure system could mean actual snow amounts or timing of the transition to snow may be different than forecast. While only a relatively small accumulation of snow is expected across Lake County, there is concern that the combination of very strong winds, quickly falling temperatures, and the likelihood for a few hours of very intense snowfall could have greater impacts on traffic than might be expected from other snow events of similar accumulation.
The most recent forecast discussion from the NWS suggests that a swath of intense snow, with snowfall rates of up to two inches per hour, will move from west to east across the region late Thursday afternoon through Thursday evening. This band of intense snow is not expected in Lake County before the evening commute on Thursday, but travel impacts could begin during the evening commute, particularly along the western portion of the county. Sustained winds over 30mph with gusts over 50mph are expected from Thursday afternoon into Friday morning, and could lead to isolated property damage or power outages. Commuters and anyone considering travel Thursday evening should plan ahead, allow extra time, make sure they and their vehicles are appropriately prepared for winter weather, and monitor updated weather information during the day Thursday. The Lake County Division of Transportation's PASSAGE system, on the web at http://www.LakeCountyPassage.com, is a valuable source of up-to-the-minute road and travel information in Lake County. At the PASSAGE website, users are able to sign up for email alerts customized to specific travel routes, and Android and I-Phone mobile device applications are available to report incidents directly to PASSAGE.
Below is the most recent version of the NWS Winter Storm Watch for Lake County and surrounding areas. Updated information can be found at the NWS Chicago website http://www.weather.gov/Chicago:
