Weather Underground Forecast for Wednesday,July 13,2016
Active weather will persist across portions of the Plains and the Midwest on Wednesday, while a ridge of high pressure builds over the Southwest.
A large area of low pressure will drift eastward across south central and southeast Canada. This system will usher showers and isolated thunderstorms over the upper Intermountain West, the northern Plains and the western edge of the upper Midwest. A cold frontal boundary associated with this system will extend south southwestward over the western Great Lakes, the upper Mississippi Valley and the central Plains. This frontal boundary will continue to interact with warm and humid air from the Gulf of Mexico, which will lead to strong to severe thunderstorms across the central Plains, the upper Mississippi Valley, the Ohio Valley and the Mid-Atlantic. Severe thunderstorms will be possible in eastern Nebraska, northeast Kansas, northern Missouri, Iowa, southeast Minnesota, southern Wisconsin, northern Illinois, southwest Michigan and northern Indiana. These thunderstorms will be capable of producing large hail, dangerous straight line winds and isolated tornadoes. Showers and thunderstorms will also develop over parts of the Gulf Coast and the Southeast.
A ridge of high pressure should keep most areas west of the Continental Divide clear of precipitation. Temperatures will rise 5 to 10 degrees above normal over parts of the Desert Southwest and the southern high Plains as high pressure amplifies across the region.
