Weather Underground midday recap for Friday, March 29, 2013.
Thunderstorm activity spread across the Southern Plains and Southeast on Friday, while widespread rain and snow spread from the Northern Rockies into the Northern Plains. A low pressure system moved off the Rockies and into the Plains, pulling Pacific moisture eastward with it. The back side of this system allowed for a few rain and snow showers to persist for the Pacific Northwest and Northern Rockies, while the leading edge of this system brought showers into Northern Plains and Upper Midwest. Many areas saw a combination of rain and snow showers as temperatures were just above freezing before the system moved in and brought cooler air with it.
Meanwhile, to the south, a frontal boundary extended from the Southern Plains through the Tennessee Valley. Moisture from the Gulf of Mexico brought energy into this system, and allowed for up scattered showers and thunderstorms to develop from northern Texas, through Arkansas, and into the Tennessee Valley. Some of these storms turned severe with large hail, strong winds, and periods of heavy rainfall. Heaviest rainfall was reported at Fort Leonard Wood, Missouri with a mid-day total of 1.09 inches of rain. There have been multiple reports of 1 inch in diameter hail across central Oklahoma.
Temperatures in the Lower 48 states Friday have ranged from a morning low of 1 degrees at Cavalier, N.D. to a midday high of 85 degrees at Edinburg, Texas
