Showers associated with an approaching low-pressure system pushed into the northwest corner just before noon where daytime highs held in the 70s, while upper 80s and low 90s were observed farther east. As the low’s attendant cold front moved over the Nebraska border, severe thunderstorms formed but lost strength over the next few hours as fireworks streaked across the sky.

Partly cloudy skies developed into the afternoon hours with pleasant highs in the 70s.

A broad area of showers and thunderstorms developed and pushed across Iowa for the remainder of the day. Temperatures were unseasonably cool statewide with upper 50s to mid-60s west to east. Most of Iowa’s stations reported measurable rainfall with widespread amounts in the 0.25-0.75-inch range in western and southern Iowa; peripheral stations measured a tenth or two with a statewide average of 0.23 inch.
