The Lake-effect snow is causing major delays and slippery conditions across Chicago area roads. Lake effect bands are expected to begin this evening and continue overnight, peaking at around midnight, according to NWS.
The morning commute was a messy one with numerous accidents reported on area expressways and schools canceled throughout the region. "Typically, these sort of lake effect bands are only 10 to 15 miles wide but can produce very heavy snow, sometimes in excess of 2 inches per hour", the warning reads. Before Monday, the last snowfall greater than an inch during this unseasonably warm winter occurred on December 17 when 1.7 inches accumulated in Chicago. The snow is expected to begin after 8 p.m. Sunday and continuing through Monday, with moderate snow at times during the morning.
Portions of Lake and Porter counties are likely to see four to eight inches of snow.More news: CLP to meet Goa Governor to stake claim for govt formation
The advisory in Will County is in effect until 4 p.m. Tuesday.
In the months of January and February, not an inch of snow accumulation was recorded in Chicago - a first in recorded history.
Significant snow risk and limited excessive cold risk are the weather hazards expected for Tuesday. Gale Force Winds are possible Tuesday, especially near the heavy snow bands off of Lake Michigan.
