A third winter storm in just a week and a half is looking more likely for portions of the state. The main question remaining isn’t will it snow, but exactly where the heaviest of the snow will be. There still is some disagreement among some of the models on where the heaviest snow will fall. Some models have the heaviest staying over the northwest portions of the state, while others bring heavy snowfall amounts into central Iowa.
A wintry mix will move into southern and southwest Iowa late Sunday into early Monday morning. This mixture of sleet, snow, and freezing rain could result in some light ice accumulation and slippery conditions Monday morning. Northwest Iowa looks to stay cold enough to keep it all snow, while southeast Iowa will likely see mainly rain during this event before changing to a mix late Monday night. Central Iowa will start as a mix, but change to all snow by Monday afternoon/evening as colder air wraps into the region.
The heaviest snow totals at this time look to fall across portions of central and northern Iowa with snowfall of 3 inches or more possible across central Iowa, and amounts of 8 inches or more possible across northwest Iowa. As mentioned earlier, southeastern Iowa will see mainly rain from this system on Monday with rainfall amounts of .25-.50”.
