NATIONAL WEATHER SUMMARY:
Across the eastern United States, a frontal boundary generated clusters of thunderstorms during the morning over much of the Tennessee Valley and Southeast. Heavy storms produced heavy rainfall amounts across Alabama. Birmingham picked up 3.44 inches of rain and Huntsville reported over 2 inches yesterday. Some of these storms were strong to severe. One severe storm in Fayette County in Tennesse produced damaging wind gusts that knocked out power over most of the western part of the county. The front also produced thunderstorms in the Carolinas. A severe storm in Montgomery County in North Carolina downed a tree. Showers and thunderstorms tapered off by late evening across most areas of the southeast. Elsewhere, scattered showers and storms also extended into Virginia, and an upper-level disturbance brought some showers to northern New England.

One severe storm knocked down power lines in Cash, AR yesterday morning. A few storms also produced rainfall over one inch.
