Weather Summary

Weather Underground Forecast for Monday, May 25, 2015

An area of low pressure will shift across the central third of the country on Monday, while the Mid-Atlantic will stay mostly clear of wet weather.

A low pressure system will lift northeastward over the upper Mississippi Valley. This system will usher moderate rain across the northern Plains, the upper Midwest, the Great Lakes, Upstate New York and northern New England. A cold frontal boundary associated with this system will extend south southwestward over the central and southern Plains. Moisture pooling northward from the Gulf of Mexico will collide with this frontal boundary, resulting in strong to severe thunderstorms over the southern Plains, the lower Mississippi Valley and parts of the Tennessee Valley. Severe thunderstorms are forecast to impact central and eastern Texas, southern Oklahoma and western Louisiana. These thunderstorms will be capable of producing large hail, dangerous straight line winds and isolated tornadoes. In addition, heavy rain associated with these thunderstorms will bring threats of flash flooding to Missouri, western Arkansas, western Louisiana, southeast Kansas, eastern Oklahoma and a large span of central and eastern Texas. High pressure over the western Atlantic will keep conditions quiet over the Mid-Atlantic.

Out west, isolated showers and afternoon thunderstorms will be possible from the Great Basin to the Rockies. The majority of the West Coast will stay relatively clear of precipitation on Monday.
