Weather Underground midday recap for Thursday, July 11, 2013.
Active weather persisted for the Eastern states and areas of showers and thunderstorms popped up from the Southwest through the Intermountain West on Thursday. A trough of low pressure and associated cold front stretched down the Eastern Valleys. Moisture from the Gulf of Mexico poured in ahead of this system, which allowed for showers and thunderstorms to develop from the Gulf states through the Mid-Atlantic states and Northeast. Some of these storms have turned severe with strong winds, hail, and periods of heavy rainfall. Trees were reported down across Westport and Coley Town, Connecticut. Heaviest rainfall was reported at Fairhope, Alabama with a mid-day total of 4.75 inches. Due to continuous rainfall over the Southeast, flooding will remain a concern for the Southeast and Mid-Atlantic states.
Meanwhile, out West, showers and thunderstorms developed across the Western states on Thursday. Monsoonal moisture over the Southwest stretched northward over the Great Basin and into the Intermountain West. This produced showers and thunderstorms from southern California and Arizona through Idaho and western Montana. Periods of heavy rainfall created flash flooding for parts of northwestern Arizona. This thunderstorm activity kept fire danger high across the Western states. Thus, fire weather warnings remained in effect for parts of Nevada, Wyoming, Idaho, and Washington state.
Temperatures in the Lower 48 states Thursday have ranged from a morning low of 41 degrees at Alturas, Calif. to a midday high of 105 degrees at Lawton, Okla.
