Weather Underground Forecast for Tuesday,June 24,2014

 

A cold frontal boundary will extend from the southern Plains to the upper Midwest on Tuesday, while a separate cold front will approach the Pacific Northwest.

A cold frontal boundary is forecast to stretch across the southern Plains, the middle Mississippi Valley, the upper Midwest and the central Great Lakes on Tuesday. As this system inches eastward over a warm, muggy air mass, widespread rain and thunderstorms will develop across the central Plains, the Mississippi Valley, the Tennessee Valley and the Ohio Valley. Severe thunderstorms will be possible over eastern Colorado, northeast New Mexico, northern Texas, western Oklahoma and western Kansas. These thunderstorms will be capable of producing large hail, dangerous straight line winds and isolated tornadoes. Thunderstorms will also bring heavy rain to the lower Mississippi Valley region, which could lead to flash flooding over northeast Texas, southeast Oklahoma and southwest Arkansas. In addition, low pressure along the northern end of the frontal boundary will usher stormy weather across the northern Mid-Atlantic and the Northeast. An onshore flow from the Atlantic will also initiate isolated thunderstorms across the Southeast.

Meanwhile, a separate cold front will dip southward over the northern tier of the country, extending from the northern Plains to the central Great Lakes. Scattered thunderstorms are expected to develop along this frontal boundary as it moves across the region on Tuesday.

Out west, a low pressure system will approach the northwestern corner of the country. This system will push light showers over the Pacific Northwest, while scattered showers and thunderstorms will be possible over the upper Intermountain West. The remainder of the West Coast will avoid wet weather due to a ridge of high pressure over the eastern Pacific.
