Snow Advisory ended – new record October 30 snowfall for Chicago

Update 10:25AM CDT…

The Winter Weather Advisory is no longer in effect. Wet snow continues to fall over the western suburbs north of Interstate-80, while light rain and drizzle occur elsewhere – the snow should change over to rain or drizzle area-wide by midday.

A record snowfall has occurred for this date with 1.0-inch reported at Midway. At Chicago’s official observing site on O’Hare International Airport the 0.9-inch established a new record for Chicago on October 30th – the old record was 0.7-inch set back in 1923. 

_________________________________________________________________________________________

Snow continues to fall across a good portion of the Chicago area this Wednesday morning with a Winter Weather Advisory calling for 1 to 4-inches of total snow accumulation across DuPage, LaSalle, Kendall, Grundy, Will, Kane and Cook Counties. The Advisory is expected to end at 10AM when snow should begin to turn over to rain or drizzle and accumulated snow will melt.

Most of the snow is accumulating on grassy areas, but where heaviest snow of 3 and 4-inches has occurred, streets could be slushy and slick.
