A slow moving storm system in the mid section of the nation will produce numerous showers and thunderstorms throughout the day and a few could become severe. The areas most likely to see severe storms extends from Iowa to Kansas into Wyoming. As an area of heat builds across the West, moisture levels will climb with humidity increasing from southerly winds blowing from the Gulf of Mexico. The energy will help to build and sustain strong storms. Most of the thunderstorm activity will form along a series of fronts and near a low pressure center. Large hail and damaging winds are the biggest risks, with the tornado threat low for today (Wednesday). Similar regions of the nation will have the threat for severe weather on Thursday and Friday. With heat continuing across the West, storm formation is likely on the edge of the heat dome. For WeatherNation: Meteorologist Mace Michaels
