Weather Underground Forecast for Monday, May 26, 2014
A trough of low pressure will linger over the southern Plains on Monday, while a cold frontal boundary will trek across the Northwest.
A trough of low pressure will continue to park itself over the southern Plains on Monday. This system will draw warm, moist air from the Gulf of Mexico to initiate showers and thunderstorms across the central and southern Plains, as well as the middle Mississippi Valley. Severe thunderstorms are forecast to develop over western Texas, which will have the potential to produce large hail and dangerous straight line winds. In addition, these thunderstorms will bring heavy rain and a chance of flash flooding to central Texas, eastern Texas and southern Oklahoma. Just to the east of this system, an onshore flow from the Atlantic will aid in producing thunderstorms across the Southeast.
Meanwhile, a cold front will extend from the northern Plains to the Great Lakes on Monday. Warm, muggy air will collide with this frontal boundary to trigger thunderstorm development from the upper Intermountain West to the upper Midwest. Heavy rain and thunderstorms will also move across the Northeast due to an area of low pressure over southeast Canada.
Out west, a cold front will push east southeastward across the Pacific Northwest. This system will usher rain across parts of Washington, Oregon and Idaho. The remainder of the West Coast will stay clear of wet weather due to a ridge of high pressure over the eastern Pacific.
Temperatures in the Lower 48 states Sunday have ranged from a morning low of 26 degrees at Wolf Creek Pass, Colo. to a high of 98 degrees at Quincy, Fla.
