Weather Underground Forecast for Thursday,August 4,2016
A low pressure system will transition across the northern tier of the country on Thursday, while widespread flooding is expected in the Southwest.
An area of low pressure will move east northeastward across the northern Plains and south central Canada. A cold frontal boundary associated with this system will stretch southwestward from the eastern edge of the Dakotas to the Great Basin. As this frontal boundary moves eastward, it will collide with warm and humid air. This interaction will produce strong to severe thunderstorms over the northern and central Plains, as well as the upper Midwest. Severe thunderstorms will be possible in eastern Minnesota, Wisconsin and northwest Michigan. These thunderstorms will be capable of producing large hail, dangerous straight line winds and isolated tornadoes.
Meanwhile, moisture-rich air will interact with the remnants of a frontal boundary, bringing widespread showers and thunderstorms to the Deep South, the Tennessee Valley, the Interior Mid-Atlantic and the Ohio Valley.
Out west, monsoonal thunderstorms will fire up across the lower Intermountain West and the Desert Southwest. There will be a threat of flash flooding in parts of Colorado, northwest New Mexico, Arizona, southern Utah and southeast Nevada. The majority of the West Coast will stay clear of precipitation on Thursday.
