Temperatures warmed into the 40s on Wednesday and Thursday — in fact, as of Thursday evening, Chicagoans had experienced 33 consecutive hours of temperatures above 32 degrees.

By Thursday afternoon, a foot of snow had melted away since Monday morning, with just 2 inches left on the ground at Midway and an inch at O’Hare.

However, a cold front moved through the area Thursday evening, followed by a surge of Canadian-source cold high pressure. Readings on Friday will be some 20 degrees colder than on Thursday, as the center of high pressure moves overhead.

Some snow is likely Saturday as we transition to warmer air, and we should see highs reaching into the middle 40s Sunday afternoon.
