Low pressure is forecast to track over Chicago this weekend. Temperatures will rise
slowly, reaching the lower 30s later this afternoon at about the same time rain spreads in
from the southwest. Some areas, especially north of the city, may experience a period of
freezing rain at the start, becoming all rain later in the evening.
Widespread freezing rain will occur farther to the north, with heavy snow expected
across northern Minnesota, Wisconsin and upper Michigan.
Rain will diminish and briefly change to snow flurries before ending early Sunday.
HEAVY SNOW AND COLD MIDWEEK
An upper-air disturbance will usher snow-producing low pressure through the Midwest
midweek with snow beginning later Tuesday in the Chicago area and continuing through
Wednesday before ending Thursday. Accumulations are likely with this storm, but the latest
forecasts place the heaviest snow well to the south and east of Chicago.
A strong northwest flow at the jet-stream level will steer arctic cold high pressure
into the northern Plains and Midwest Wednesday, and then persist over Chicago the remainder
of the week.
