Weather Underground Forecast for Saturday, May 31, 2014
An area of low pressure will continue to inch across the Gulf Coast on Saturday, while a cold frontal boundary will extend from the Great Basin to the upper Midwest.
A cold front is forecast to stretch from Nevada to Minnesota on Saturday. As warm, muggy air from the Gulf of Mexico collides with this system, heavy rain and thunderstorms will develop over the upper Intermountain West and the Plains. Severe thunderstorms will be possible over southeast Montana, eastern Wyoming, northeast Colorado, western Nebraska, western South Dakota and southwest North Dakota. Heavy rain associated with these thunderstorms will also bring a threat of flash flooding to eastern Montana, northeast Minnesota and northwest Wisconsin. Scattered showers and thunderstorms will be possible over the eastern tier of the Four Corners. The West Coast will avoid precipitation on Saturday due to a large ridge of high pressure over the eastern Pacific.
A low pressure system will begin to weaken along the Gulf Coast, although rain and thunderstorms will continue to move across the lower Mississippi Valley, the Tennessee Valley, the Gulf Coast and the Southeast. Meanwhile, parts of the Northeast will have a chance of morning rain as an area of low pressure moves northeastward off of the coast of New England. High pressure will build to the west of this system, which will bring clear skies to the Ohio Valley and the Mid-Atlantic on Saturday.
