LAKE EFFECT SNOW - SHORT TERM UPDATE #2

As advertised, lake effect snow spread across a good portion of Northeastern and Eastern Illinois over the past several hours. At this early hour on this Monday morning, while snows are widespread across the aforementioned areas, two areas of greatest focus exist.

This first area extends across Southern Cook, Eastern Will, Kankakee and portions of Ford and Iroquois Counties. Across this area, lake effect snow is being enhanced on the backside of a meso-low sliding southward just to the east of the area. This area will continue to be of focus over the next few hours.

The second area is across Eastern Lake County. Across this corridor, a single main band of lake effect snow has become close to stationary. This will continue to be the case over the next few hours, before activity shifts to the east.

While general snowfall accumulations will be widespread, greatest expected snowfall accumulation will be in and near the two corridors discussed.
