An intense low pressure system continued to move across the nation on Sunday, bringing more thunderstorms and tornadoes to the East. By late afternoon on Sunday, the storm sat squarely above the Mid-West. Several twisters were reported on Sunday, with one in Georgia causing complete structural damage to a building. The roof of that building was blown onto I-95 near milepost 50. Large hail and high winds were also reported in association with this storm, causing scattered damage throughout the Southeast and Kentucky Valley.

In addition to the damaging winds and tornadoes caused by this storm system, flooding intensified along the Upper Mississippi river valley even as heavy precipitation wound down in the region.

The storm also brought cool Canadian air southward into the nation, and temperatures in the Plains and Appalachians fell well below normal for this time of year. The East Coast saw a mix of temperatures, the Mid-Atlantic experienced cool weather, while the New England interior was quite warm.

Temperatures in the Southwest and California were also pleasantly warm, while a weak trough in the Northwest brought some chilly temperatures and scattered precipitation to the region.

Temperatures in the Lower 48 states Sunday have ranged from a morning low of 6 degrees at Rush City, Minn to a midday high of 96 degrees at Okeechobee, Fla.
