Sunday snow followed by more bitter cold
After a couple quiet, but cold days some snow is back on the table as the weekend comes to a close.
Sunday southerly winds will boost temperatures into the teens and low 20s, and will also bring in some moisture which will get squeezed out in the form of snow as a clipper system dives southeast out of Canada.
Light snow will develop late Sunday afternoon and sweep across the area from northwest to southeast through the evening before tapering off overnight into early Monday morning.
Accumulations of 1-3" of fluffy snow is likely with the higher totals north of Highway 20 into northeast Iowa. Further south to I-80 amounts will be in the 1-2" range with generally 1" or under into southern Iowa.
Snow will not be the only concern with this system as gusty winds and more bitter cold arrive heading into the new week.
As it passes winds will increase out of the northwest with gusts over 30 mph resulting in blowing and drifting snow especially into the Monday morning hours.
Temperatures will plummet through the single digits on Monday dropping well below zero by Tuesday morning. Wind chills will be at dangerous levels approaching -30 (or colder) and frost bite can set in quickly on any exposed skin in less than 10 minutes so bundle up!
However, there is good news! This cold blast won't last that long as the flow turns to the southwest by the end of the week as mild, Pacific air filters back in with temperatures warming into the 30s and possibly low 40s by the weekend.
