NATIONAL WEATHER SUMMARY:

Yesterday in the East, a frontal boundary produced clusters of thunderstorms in central/western New York as well as Lower Michigan during the afternoon hours; many of these storms became severe.

Severe storm in North Brookfield, New York and North Branch, Michigan produced golf ball sized hail. Meanwhile, an upper-level disturbance generated scattered thunderstorms across the coastal Carolinas, southern Georgia and much of Florida. Rainfall totals in these areas generally ranged from 0.25" to 0.75", but several locations in Florida received over 1" of rain. There were also scattered light showers and thundershowers yesterday in the Deep South and over northern New England.

In the central United States yesterday, clusters of thunderstorms were ongoing in the morning across parts of the Dakotas and Minnesota due to a frontal boundary. Most of these storms dissipated in the afternoon. However, storms that moved in Wisconsin strengthened and became severe.

There were several reports of large hail and damaging wind gusts in central and southern Wisconsin yesterday afternoon and evening. Tennis ball sized hail fell in Chilton, Wisconsin. There was also a tornado reported near Sheboygan Falls, Wisconsin. This cluster of storms generated rainfall totals over 1" in southern Wisconsin. Additional strong to severe thunderstorms developed south of the front in South Dakota and Nebraska yesterday afternoon and evening. Baseball sized hail fell in Lyman County in South Dakota. Elsewhere, scattered showers and thunderstorms developed over Oklahoma and Texas, but no severe storms occurred there.

Yesterday in the West, monsoonal moisture led to scattered afternoon

thunderstorm development throughout the Rockies, Four Corners Region, and parts of the Desert Southwest and interior southern California. A cluster of severe storms developed near the Montana/Wyoming border, with 70 mph wind gusts reported in Powder River County in Montana. Campbell County in Wyoming reported 60 mph wind gusts.
