The forecast period begins with a few lingering showers moving across southwestern Iowa. These should exit the region before midnight. CAMs show a possibility of a few additional showers overnight and early into Sunday morning. Sunday morning lows will be mild, ranging from the upper 50s to low 60s.

A broad area of low pressure will be in place over Saskatchewan, Manitoba and the Dakotas heading into Sunday morning. A mid-level shortwave trough lifts through the region Sunday afternoon, bringing lift to the area. With WAA and moisture also advecting into the region, we could get some additional chances for showers and thunderstorms Sunday morning, but especially into the afternoon and early evening hours. The area remains in a marginal risk for severe thunderstorms. Expected highs will top out in the mid-70s to mid-80s in the afternoon. Minimum RH value will fall into the 20s for northeastern Nebraska Sunday afternoon; however, the stronger winds that could reach RFW criteria will not be co-located with the areas that have the lowest RH values.

Monday will be quite summer-like in temperatures. Expected highs will reach the low to mid-80s across the region. Monday afternoon, RH values will fall into the mid-teens to mid-20s for more of the region. Expected wind gusts are currently forecast to be below criteria in areas with the lowest RH values. This will be something to continue to monitor in the coming 24 hours. Another shortwave trough will lift into the region, bringing a chance for shower/thunderstorm activity. Should any thunderstorms find a way to develop, they could become strong to marginally severe.

Tuesday brings another shortwave trough lifting from the Four Corners up into north central Kansas and south central Nebraska by Tuesday evening. Highs will range from the mid-70s to mid-80s across the region. Expect additional chances for showers and thunderstorms, a few of which could become strong to severe.

Wednesday through the end of the extended forecast, a series of disturbances will loft into the region. This will lead to the potential for some periodic showers and thunderstorms.
