Excessive rainfall is possible Monday across the Tennessee Valley and Mid Atlantic.
A disturbance lifting out of the Gulf of Mexico will track along a stationary boundary draped from the Florida Panhandle to the Carolinas. Ongoing showers and thunderstorms are expected to continue throughout the day with training showers along the front expected to bring excessive rainfall to portions of the Southeast and Mid Atlantic. Widespread accumulations of 1-2 inches will be possible along the front, but some areas may pick up in excess of 2 inches across Northern Georgia and into the Carolinas. Flooding and local runoff will be possible, however, major impacts are not anticipated.
Elsewhere, a developing trough over the Western US will begin moving into the Four Corners and Central Rockies this afternoon with scattered showers increasing from Central California into the Northern Rockies. Light to moderate snow is expected for elevations above 6000 feet from the Sierra Nevada into the Wasatch Range of Utah, but should pose minimal impacts.
