The National Weather Service reports severe thunderstorms are possible across much of the area this afternoon and tonight. There is a slight risk of severe storms primarily this afternoon and evening but storms may linger overnight. The main time-frame is from 3-until 11-p.m.  Large hail, damaging wind and heavy rainfall are the main threats. Unfortunately, for western and parts of southwest Iowa, there is only a marginal to slight risk of excessive rainfall, while some areas could see anywhere from one-to-three inches of rain.

Tornadoes are a secondary threat with today’s weather. Hot and humid conditions will exist this weekend. Heat index values may be in the 100 to 105 degree range. Additional thunderstorms are forecast Sunday evening. Some storms may be severe but the specific threats and timing of which will be better determined in the coming days.
