2016 will be ending on a quiet note, with above average temperatures, but just as the calendar changes to 2017, our weather will be changing too. Over the past few days, we have been on the upward trend on the temperature roller coaster.
Highs over the weekend will be in the 30’s to 40’s, which is 5 to 15 degrees above average for this time of year. By late Sunday, this is when the weather begins to go south. Beginning late Sunday through early Tuesday morning, chances for rain and snow will move through the state. The best chances will be Monday morning and afternoon.
The main concern right now will be precipitation type. Primarily snow will be seen across extreme northwest Iowa and rain across the south with a mix likely across northern Iowa through the day. Some light icing may be possible, but this will still need to be closely monitored, as the freezing line could still shift north or south. Minor ice accumulations of 0.1″ to 0.15″ are currently forecasted across northern Iowa, as shown below.
Once that system moves out of the area Tuesday, high pressure and cold temperatures will filter into the state. Lows from the middle to end of the week will likely drop into single digits and teens, with a few places across the north below zero. Morning wind chills will dip toward -20 at times across the north to below zero down towards the Missouri border. Highs will range from the single digits across the north to teens down through the state.
