Winter Storm: Mar 10

Although only a small portion of the state will see winter precipitation, this will still be one of the main highlights of our storm system that is currently effecting the state. While thunderstorms and showers should dominate the forecast for all but northwest Iowa, this will create the potential for additional flooding and overall saturated conditions. Storm total precipitation should range from a few tenths across the diagonal of the state to upwards of a half inch across southeast Iowa. These heavier amounts are likely to come from isolated thunderstorms, some of which over extreme southeast Iowa may be able to reach severe limits with strong winds and large hail. Across northwest Iowa, a mixture of sleet and snow seems likely, along with some freezing rain during the early hours of the event. Snow accumulations should generally only be 1-3 inches for areas that are currently under a Winter Weather Advisory; other parts of the state bordering this advisory will see snowfall but generally no accumulations.

The other part of this storm system will be the cold air funneling in behind the low pressure system, and the strong winds that will move in tomorrow afternoon and overnight. Highs tomorrow will range from near 20 in northwest Iowa as they remain to in the cold air; while southwest Iowa will attempt to reach the 60s in the warm sector of the low pressure system. The cold air moves through the entire state by Tuesday night, bringing lows down into the single digits across northwest Iowa and the upper teens across southeast Iowa. Highs on Wednesday will only reach the teens across the northwest, and the lower 30s across the southeast. We'll look to slowly warm-up through the week, and continue to warm into the weekend.
