Lake County IL Winter Weather Advisory                               

Thursday, February 21, 2013 08:20 a.m.

 

Emergency Management Partner Update

 

Lake County and much of the central United States will be impacted by a large storm system over the next two days. In Lake County, light snow is expected to begin this evening, with snow increasing in intensity and perhaps a few hours of snowfall rates of up to an inch an hour, before tapering off and changing to light freezing drizzle Friday morning. General snowfall amounts of three to five inches are expected across the Chicagoland area, and while there may be local variations in total snowfall, there has been consistency between the various weather models and forecasters are confident in the overall forecast. There is also a possibility of some light lake-effect snow during the day today, and although no significant accumulation is expected, there may be periods of some reduced visibility, particularly nearer to the Lake Michigan shoreline. The National Weather Service has issued a Winter Weather Advisory which will be in effect from 9:00 p.m. tonight through 6:00 p.m. Friday evening.

 

Impacts: Snow, light at first, beginning between 7:00 and 9:00 p.m., increasing into the early morning hours before tapering off and eventually switching to light freezing drizzle. Snow accumulation of 3 to 5 inches, and light glazing of ice, particularly on elevated porches, stairways, sidewalks, and bridges. Strong gusty winds overnight may cause some blowing of snow. Pedestrians and motorists should anticipate the possibility of hazardous conditions, particularly Friday morning.

 

Protective actions: People should allow extra time for travel Friday morning. Motorists should make sure their vehicles are appropriately prepared for winter weather, including keeping the fuel tank full, having a winter emergency kit with blankets and food, and having a fully-charged cell phone and car-charger with them when they travel.
