The cold, arctic air is settling in across eastern Iowa today, aided by a little bit of snow on the ground. Highs will be in the teens for most with 20's expected in Iowa City and Washington. The skies have opened up and a cold sunshine is forecast today. A few clouds in the southwest may hold a few flurries.
Clouds will increase tonight ahead of a little clipper system that will bring quick moving light snow to the area overnight. The snow looks to move in after midnight and move out by the morning commute.
Roads could still be slick for Wednesday morning with up to 1” of accumulation possible. Most of this will be south of Waterloo and Dubuque.
Otherwise, temperatures get the coldest this evening with steady or rising temperatures through the overnight hours. It will be cold regardless with lows in the single digits rising to the low teens.
Behind the snow, clouds will clear again for Wednesday with sunshine. The cold air sticks around with highs in the teens north and 20's south thanks to less snow on the ground.
There will be another chance for light snow on Thursday, mainly north. A stronger south southwest wind will give us a 20° boost in high temperatures.
Conditions stay mild on Friday with mostly cloudy skies. Light snow will move in Friday night and Saturday, bringing an arctic front with it. That will drop our temperatures with a strong northwest wind. That will leave another cold sunshine for Sunday. Temps should start to warm by early next week.
