Weather Underground midday recap for Friday, May 17, 2013.
A broad low pressure system developing over the Plains brought multiple areas of wet weather to the nation on Friday. Flow ahead of this system pushed warm and moist air into the Eastern Valleys from the Gulf of Mexico, allowing for widespread showers and thunderstorms to develop across the Tennessee Valley. This system also moved northward into the Ohio Valley, and extended southwestward into far eastern Texas. Some of these storms have turned severe with strong winds, hail, and heavy rainfall. Quarter size hail was reported in Frost and Corsicana, Texas. Pine Bluff, Arkansas reported a mid-day total of 3.20 inches of rain.
Meanwhile to the north, a warm front extended eastward over the Upper Midwest and into the Great Lakes, which kicked up heavy rainfall with isolated thunderstorms. Heaviest rainfall was reported in Rochester, Minnesota with a mid-day total of 1.26 inches of rain. The back side of this broad low pressure system continued to pull a front over the Western states. While Pacific moisture continued to feed energy and moisture into the region, widespread showers and afternoon thunderstorms persisted for the Intermountain West, Northern Rockies and Great Basin. To the south, ahead of this front, strong and gusty winds developed across the Southwestern states. Due to dry conditions, warm temperatures, and these gusty winds, high fire danger warnings were issued from Arizona through Colorado and into western Texas.
Temperatures in the Lower 48 states Friday have ranged from a morning low of 24 degrees at Mt. Washington, N.H. to a midday high of 101 degrees at Breckenridge, Texas
