A cold frontal boundary extending from the southern Plains to the Southeast will interact with a warm, humid air mass streaming northward from the Gulf of Mexico. As these two systems collide, widespread rain and thunderstorms will develop across a handful of states. Severe thunderstorms will be possible across southeast Colorado, eastern New Mexico, northern Texas, Oklahoma, southern Kansas, Arkansas, southern Missouri, northern Mississippi and western Tennessee. These thunderstorms will be capable of producing large hail, dangerous straight line winds and isolated tornados. In addition, heavy rain will accompany these thunderstorms, which could lead to flash flooding over northern Texas, Oklahoma, southeast Kansas, northern Arkansas, Missouri, southern Illinois, northwest Tennessee, western Kentucky and southwest Indiana. Scattered showers and thunderstorms will also be possible across parts of the Ohio Valley, the eastern Tennessee Valley and the Southeast.
A separate cold front will stretch from the central Plains to the upper Midwest. This system will bring rain and thunderstorms to much of the northern Plains and the upper Midwest on Saturday. Scattered showers will also linger over the upper Intermountain West.
Out west, a ridge of high pressure will build over the eastern Pacific, keeping conditions warm and dry across the West Coast. Temperatures will approach 110 degrees across the Desert Southwest.
Temperatures in the Lower 48 states Friday have ranged from a morning low of 25 degrees at Stanley, Idaho to a high of 105 degrees at Needles, Calif.
