Another storm chance on Tuesday

Courtesy Storm Prediction CenterThe Storm Prediction Center includes the western half of Appanoose County in the enhanced risk category for severe weather Tuesday.

The western portion of Appanoose County faces an enhanced risk for severe weather Tuesday.

The Storm Prediction Center's latest swatch of enhanced risk stretches from northeastern Oklahoma up to southwest and southcentral Iowa Thursday. All types of severe weather are possible, though hail is a significant threat, according to the center.

While the area has largely avoided previously forecasted severe weather in previous days, it hasn't avoided the rain. Rain over the weekend brought about 1 inch to the Centerville area. Nearly 2.5 inches of rain was measured at the co-op gauge six miles northeast of Centerville.

The Chariton River at Moulton again touched flood stage over the weekend, but quickly rescinded. Levels at Rathbun Lake continue to rise, with Monday measuring 911.75 feet above mean sea level. The normal operating pool is 904 feet.

As it stands, the U.S. Army Corps of Engineers expects the lake to crest at 914.11 by Friday or Saturday. However, that doesn't take into account the forecast rainfall. Approximately 1 inch is expected to fall on Tuesday. Rain chances are present for most of the days in the upcoming seven-day forecast.

The National Weather Service forecast shows consistent rain chances throughout the day Tuesday, with probabilities rising in the afternoon, when severe weather is expected to arrive. Thundering clouds and severe weather threats are expected into the overnight hours.

The Des Moines River in Ottumwa is expected to hit moderate flooding Wednesday as it continues to rise. The river was at 13.3 feet Monday, but forecasters think it will hit a new crest of 16.1 feet Wednesday evening. It will drop after that, but not for long.
