Another mild week setting up for Chicago

With nearly all of last week’s snowfall melted, the second week of December is setting up to be a relatively mild one for the Chicago area.
The warmest weather will occur today and early Tuesday when highs are expected to top out in the upper 40s and lower 50s. But even when colder weather moves in for the rest of the week, daytime highs are still expected to remain above the mid 30s readings typical here this time of the year.
Precipitation is forecast to be primarily liquid with rain expected today into Tuesday and again toward the weekend. And though some light snow or flurries can’t be ruled out, no significant snowfall is in sight.
In contrast, cold and snow continue to plague the West. Las Vegas could only muster a high of 46º Sunday and has not recorded a reading higher than 54º in more than a week. Heavy snow warnings are posted for the higher elevations of southern Arizona with up to 12” of snow expected.
