Chicagoland weather radar [LIVE PRECIPITATION TYPE RADAR] shows an area of snow moving west to east along a line just north of Interstate 80 and approaching Joliet at 1:50 p.m.
Snow is expected to gradually push north. The snow we are about to receive is not another of the Alberta Clippers that we have been hit with week after week. We’re about to experience a good old-fashioned Low Pressure hook, which will mean heavy, wet snow, and ice and rain just to the south of the heavy snow line.
Snow is likely to start in Arlington Heights and the northwest suburbs some time between 6:00 p.m. and 10 p.m. Friday with the heavier snow and faster accumulation after midnight. The forecast calls for about 2.3 inches by 6:00 a.m. Saturday morning and a final total of 6.5 inches by 6:00 p.m. Saturday. The approaching system could track further north, which could bring heavier snow to the northwest suburbs — in the neighborhood of 6-8 inches. The shift would also bring a larger area of freezing rain and winter mix to the south and southwest suburbs of Chicago. Ice accumulation is expected to be less than one-half inch in the south suburbs.
Satellite images show that much of Illinois is under clouds, with the storm system clearly defined.
Mostly cloudy conditions are forecast to continue today and Saturday with clearing after 7:00 p.m. Saturday, along with a temperature drop — 26 degree at 4:00 p.m. down to 4 degrees at 5:00 a.m. Sunday.
Wind gusts of 17-20 MPH from the north and northwest are forecast from 11:00 a.m. to midnight late Saturday.
