Weather Underground midday recap for Friday, April 25, 2014
A cold frontal boundary extended from central California to the upper Intermountain West on Friday, while a separate cold front stretched from the eastern Gulf Coast to the Ohio Valley.
A cold front moved eastward over the eastern third of the country on Friday, which brought active weather to a handful of states. A warm, muggy air mass from the Gulf of Mexico interacted with this frontal boundary to produce strong to severe thunderstorms over the Mid-Atlantic and the Ohio Valley. The strongest thunderstorms developed over the Mid-Atlantic as severe thunderstorm warnings and tornado watches were issued in North Carolina and Virginia. Durham, N.C., reported a midday total of 1.00 inches of hail, while Cumberland, N.C., reported a midday total of 0.50 inches of hail. Heavy rain accompanied these thunderstorms, as Mount Sterling, Ky., reported a midday total of 0.93 inches of rain. A mixture of rain and snow also developed along the upper Great Lakes on Friday.
A separate cold front extended from central California to southern Idaho, as moderate to heavy rain moved across California, Nevada and Idaho. Blue Canyon, Calif., reported a midday total of 1.54 inches of rain, while Placerville, Calif., reported a midday total of 1.09 inches of rain. This system also ushered heavy snow across the Sierra Nevadas, as Placer, Calif., reported a midday total of 7.0 inches of snow. Scattered showers lingered over Oregon and Washington due to an onshore flow from the Pacific. The central third of the country stayed clear of precipitation on Friday due to high pressure over the central Plains.
Temperatures in the Lower 48 states Friday have ranged from a morning low of 15 degrees at Mt. Washington, N.H. to a midday high of 91 degrees at Dryden, Texas
