Winter Storm Tuesday (Update)

posted Mar 4, 2013, 9:25 AM by Brian Donahoe   [ updated Mar 5, 2013, 7:44 AM ]
from Tuesday morning

A National Weather Service (NWS) Winter Storm Warning for heavy snow is in effect for northeastern Illinois, including Lake County, from 9:00 a.m. today through midnight tonight. There have been some changes in the expected location of the heaviest snowfall with this complex system, and the current forecast is for the axis of greatest snowfall will be west and south of Lake County. Intermittent snow is expected to continue through the morning, becoming more consistent and intense this afternoon. The most intense snowfall, with accumulation rates of an inch per hour possible, is expected this afternoon. Winds from the northeast of up to 20mph with stronger gusts are expected during the day Tuesday. The intense snowfall and strong winds will lead to periods of reduced visibility and hazardous travel, and the winds may cause some blowing and drifting of snow. Snow is forecast to taper off Tuesday night, with only occasional snow possible through Wednesday.

 

Detailed weather information is always available through the NWS website http://www.weather.gov/Chicago, by clicking on the appropriate location on the map or by providing the ZIP code for the community in the search box in the upper left corner of the web page.

 

The most up-to-date travel and roadway information is available from the Lake County Division of Transportation PASSAGE system, available on-line at http://www.lakecountypassage.com, through highway advisory radio at 1620 AM, or via the free I-Phone and Android smart-phone applications.

 

Impacts: Snow, intense at times, will likely lead to travel challenges Tuesday afternoon and evening. Traffic on the roads and intense snowfall may cause challenges for crews working to clear snow, and motorists should plan ahead and be prepared for hazardous driving conditions. Periods of intense snow will reduce visibility, and strong northeast winds may lead to blowing and drifting of snow. Snow accumulation of 4 to 8 inches is expected, but locally higher amounts are possible. Motorists should allow extra time for travel, and be sure to have appropriate emergency supplies, including a charged cell phone, in their vehicle.

 

As a result of the expected Winter Storm, the National Weather Service has POSTPONED the Illinois Statewide Tornado Drill that had been planned for Tuesday morning. The tornado drill is now planned to occur Wednesday morning, March 6th, at 10:00 a.m.

Original post

The National Weather Service (NWS) has issued a Winter Storm Warning for Heavy Snow for northeastern Illinois, including Lake County, from 3:00 a.m. Tuesday morning through midnight Tuesday night. While there is still some uncertainty about the exact track and location of the axis of heaviest snowfall, there is enough confidence to suggest that most of the Chicagoland area north of Interstate 80 will receive six or more inches of snow. Light snow may begin over Lake County later today or tonight, with moderate snow possible during the morning Tuesday. The most intense snowfall, with accumulation rates of an inch or more per hour, is expected Tuesday between noon and 6:00 p.m. Snow is forecast to continue into the night Tuesday, and occasional snow is also possible Wednesday morning. Winds from the northeast of up to 20mph with stronger gusts are expected during the day Tuesday, which may cause challenges with blowing and drifting of snow, particularly on east-west roadways.
