UPDATE 11:30AM: An Arctic front moving through Chicago in the wake of last night's snow is delivering a reinforcing shot of very cold air to the region. Temperatures that peaked this morning around 22 degrees are falling sharply this afternoon into the lower teens. The cold air is here to stay as readings will remain below 20 degrees for most of the metro area until Monday.

UPDATE 10:30AM: Several waves of light snow have developed over northern Illinois in the wake of a departing Alberta Clipper storm system. The snow is expected to taper to flurries by early afternoon with additional accumulation under 0.5". In northern Indiana, lake effect snow is expected later today in La Porte county. An additional 1 to 2 inches of snow is possible around and near Michigan City.

UPDATE 7:30AM: Road conditions this morning range from snow covered with black ice on untreated roads, to wet on some of the better maintained streets and highways.
With temperatures expected to remain 5 to 12 degrees below freezing today, many roads will remain slick with the possibility of re-freeze.
