Super Snow Sunday Chicago

January 31st, 2015 by Roy W. Spencer, Ph. D.

A vigorous low pressure tracking eastward from Colorado will intensify and bring up to a foot of new snow and near-blizzard conditions to Chicago by tomorrow afternoon.

Similar conditions will occur across central Iowa, northern Illinois, Indiana, Ohio, southern Lower Michigan and Detroit, and then spread eastward with 6-12 inches of snow for New York City through Boston by Tuesday morning (all graphics courtesy of, click for full size):

The low pressure and precipitation areas forecast for Super Bowl game time suggest that being parked in front of the TV will be a safer activity than being out driving in a car:

    Well it looks like I know where I’ll be going on Sunday. I live right on the line between the red and blue in Indiana. I go back on call at 06:00 Sunday. Looks like odds are that I’ll be heading back north and east again.

  2. Thanks, Dr. Spencer.
    I was told that in the very near future snow would be a thing of the past. But looking at the NCEP GFS weather model it seems the present is not here yet.
    Soon we shall see what January looked like on a global temperature scale, thanks to you and Dr. Christy’s excellent work.

      (And, definitely thanks Dr. Roy. I especially appreciate these previews/forecasts of large weather systems. Please keep us forewarned.)

    The air will turn bitterly cold in the wake of the storm from the Midwest to the Northeast. Actual temperatures will dip to the single digits to near zero in the swath from Philadelphia to Boston by Tuesday morning. AccuWeather RealFeel® Temperatures will dip well below zero from Washington, D.C., to Boston, northwestward to the lower Great Lakes.
