A focus shift from snow to the cold for Presidents Day

MILWAUKEE (CBS 58)--Getting hard to keep track of what Mother Nature is throwing at us.  Almost.  The snow shower activity should subside later on Sunday as colder air takes over the area.  Perhaps a slight accumulation in some spots.  Then we focus our attention on plummeting temps into Sunday night.  A Cold Weather Advisory will be in place late Sunday night through much of Monday morning. Of course Monday is Presidents Day.  It'll feel like -20 to -30. Please limit your time outside to less than 15 minutes.  Frostbite can set up in less than a half hour.  The cold stays intact through much of the coming week.  I don't see temperatures going above freezing for a week either.  

Cold air arrives into Sunday night...
