Weather Underground midday recap for Friday, May 30, 2014

A low pressure system continued to linger over the lower Mississippi Valley on Friday, while a cold frontal boundary stretched from the Southwest to the upper Midwest.

An area of low pressure inched slowly eastward over the lower Mississippi Valley and the central Gulf Coast on Friday. This system drew warm, muggy air from the Gulf of Mexico, which continued to initiate heavy rain and thunderstorms across a handful of states. Flash flood watches remained in place over southeast Louisiana and southern Mississippi as heavy rain pushed across the region. Shreveport, La., reported a midday total of 1.10 inches of rain, while Pine Bluff, Ark., reported a midday total of 1.55 inches of rain. Isolated showers and thunderstorms also developed across the Southeast, as Barnwell, S.C., reported a midday total of 1.70 inches of rain. Meanwhile, a cold front extended from the eastern Great Lakes to northern New England, which initiated showers and thunderstorms across the northern Mid-Atlantic and New England.

A separate cold front stretched from southern Nevada to northwest Minnesota on Friday. A cluster of thunderstorms pushed across Colorado, Wyoming, western Nebraska and the Dakotas as flash flood warnings were issued across the region. Scattered showers also moved across the Four Corners. The West Coast avoided wet weather due to a ridge of high pressure over the eastern Pacific. Temperatures ranged between the 90s and 100s across the southern California and Arizona deserts, as Glendale, Ariz., recorded a midday high of 100 degrees.

Temperatures in the Lower 48 states Friday have ranged from a morning low of 21 degrees at Stanley, Idaho to a midday high of 100 degrees at Glendale, Ariz.
