Snowstorm & Extreme Cold

Another system is forecasted to hit the state of Iowa on Wednesday and last into Thursday, behind it is going to be true arctic air. If you think the past couple days have been cold, then you might not want to be outside much at all for the remainder of the week. Temperatures in the teens and 20s for highs today will continue tomorrow, with even warmer temperature in place as southerly winds increase. Highs nearing 40 in extreme southeast Iowa aren't out of the question as the lack of snow is letting the ground warm nicely. Wednesday night lows will however begin to show the arctic air spilling into the northwest, single digits are expected for much of western Iowa, teens and a few 20s for the eastern half.

Wednesday into Wednesday night will also the beginning and the heaviest part of the storm system that is expected to move into and over the state. Light to moderate snow is expected across much of the state during the day, with the heaviest over southern Iowa. As we move into the nighttime hours the heaviest bands of snow are expected to work across much of the central portion of the state. Current models are showing higher than expected amounts, but nonetheless a good 3-6 inches with higher amounts certainly possible is the going forecast. To read the latest issuances of advisories/warnings, check out my homepage or you can click here to read the latest Snow Advisory for southwestern Iowa and Winter Storm Watch for much of the state. Not only will the snowfall be a concern, but winds are expected to increase and create blowing snow and potentially near blizzard conditions across the state. Extreme cold is also going to combine with this wind to create frigid and dangerous conditions...

As this system exits, behind it enters the arctic air with highs in the single digits to lower teens across the state. Lows below zero across the state, with some negative teens expected in the north and especially northwest. More updates on the potential winter storm as forecasts are adjusted and new issuances of advisories/warnings continue.
