It was another cold day with temperatures this morning below zero and afternoon highs in the single digits and low teens. Clouds have been increasing across eastern Iowa this afternoon. Here is a visible satellite image from this afternoon.

The band of clouds over us tonight produced some light snow in western Iowa and eastern Nebraska last night. We will have a chance of light snow or flurries tonight with the potential for light accumulation (less than 1”) in some spots. Flurries will continue into Wednesday morning.

High pressure will move south into the Midwest and clear the clouds Wednesday afternoon. The sky will be clear Wednesday night and it will be colder across the northern half of the viewing area. Some locations will drop below zero again for morning lows. Here is the HPC surface map for Wednesday evening.

Clouds will increase Thursday afternoon with chance of light snow Thursday night. There might be a few flurries lingering into early Friday morning, but for the most part the light snow would be confined to Thursday night. Some light accumulation is possible.

Friday and Saturday will be partly cloudy with a gusty northwest wind Friday and a much lighter wind Saturday.

We are tracking the potential for some active weather Sunday through the first half of next week. Sunday could be a sloppy day with a wintry mix of rain/freezing rain/sleet and snow. It is too early for any specifics on precipitation type/location and amount. Here is the GFS model showing the critical thicknesses. Each of the colored lines could potential be the “rain/snow” line. The pink shading is the precipitation.

Here is an early look at the amount of moisture in the system from Friday evening through Sunday evening. Since there will be no precipitation Saturday the amount on the map from the HPC is for Sunday.
