OTTUMWA — It’s going to be a warm weekend in southeast Iowa, though not as hot as it was last week. But another round of thunderstorms could cap things off again.

Temperatures Saturday and Sunday will reach near 90 degrees, with overnight lows around 70. That’s a bit above normal, but not all that unusual for summertime. Sunday night and Monday could see some thunderstorms as temperatures return to normal.

Last week’s heat wave broke in dramatic fashion as severe storms pummeled the area Saturday evening. The storms brought cooler air, which was welcome for area residents. They also brought widespread damage to trees and some buildings.

Sunday’s storms do not look like they will match their predecessors. As of Friday, the Storm Prediction Center gave western Iowa only a marginal risk of severe weather, and none was expected in the eastern half of the state.

That can change, of course. The SPC didn’t give southeast Iowa much of a chance of severe storms until the day storms hit last week, and even that was a slight risk.

There are some differences. Sunday’s storms are not expected to arrive until after 8 p.m. Sunday night has a 50 percent chance of storms, the same as Monday does. A later arrival could weaken storms before they reach the area. While severe weather is certainly possible during overnight hours, it’s much more common in the late afternoon and early evening.

The standard advice remains the best bet. Make sure you stay aware of conditions if storms are in the forecast, and have multiple ways to receive warnings if the storms turn severe.
