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.

In the central United States, the trailing edge of a frontal boundary brought thunderstorm complexes to southern Nebraska, eastern Kansas, southwestern Missouri, northeastern Oklahoma, and Arkansas. One severe storm knocked down power lines in Cash, AR yesterday morning. A few storms also produced rainfall over one inch. A developing low pressure system produced severe storms during the afternoon across the Dakotas. Golf ball to baseball sized hail covered the ground up to 6 inches deep in some places near Ree Heights, SD. Thunderstorms continued to develop from ND to western NE and eastern CO during the evening and overnight hours. A trained spotted reported a funnel cloud near Valentine, NE and a large tornado was reported near I-90 in far northeastern WY.
