Winter Storm Warning In Effect Until 11am: Storm Impact Diminished; 2.5 Inches At 4:30 Am, Another 0.7 Expected

Chicagoland weather radar shows precipitation is east of northwest Cook County and about half of DuPage County as of 6:30 a.m.

An approaching Winter Storm got a late start last night and is possibly going to have less impact then initially forecast. NWS forecasters have already moved up the expiration time in Arlington Heights from 1:00 p.m. to 11:00 a.m. There is also the possibility the Winter Storm Warning will expire before 11:00 a.m.

Bottom line? 1) Less snow has accumulated than expected, and 2) winds may not cause the blowing snow that was expected.

Winds have caused some trouble with power lines in the area. About 54 customers were reported without power in Deerfield, about 94 customer were reported without power in Schaumburg, and about 73 customers were reported with out power in Des Plaines at 4:40 a.m.

As of 4:30 a.m. 2.5 inches of snow had accumulated in Arlington Heights overnight.

Very little additional snow is expected as the radar shows the precipitation is clearing the area.

Significant weather news is a wind chill down to 9 degrees by noon Wednesday, and as low as 5 degrees Thursday at 7:00 a.m.

Winter Storm Warning is in effect until March 12, 11:00 AM CDT
