Despite the fact that Chicago’s seasonal snowfall this winter is less than half of normal, February to date has been a very snowy. The month’s 10.1 inch total is running 136 percent of normal and has accounted for nearly 75 percent of this winter’s total anemic snowfall of 13.6 inches. A new storm system is expected to sweep across the Plains and Midwest on Monday and Tuesday threatening to produce a variety of wintry weather. Precipitation here should begin as a wintry mix of rain, freezing rain, sleet or snow late Monday night and gradually transition to a heavy, wet accumulating snow on Tuesday as the storm entrains colder air. The cold air will take up residence for the rest of the week as the storms heads east with daily high temperatures expected to remain well below the current seasonable normals that are approaching 40 degrees. Friday’s start of meteorological spring will be anything but spring like, with gusty, wind-blown snow flurries and high temperatures struggling to reach 32 degrees.
