DISCUSSION

Issued at 120 AM EDT Thu May 7 2026

The cold front is currently stalled near the Cumberland Plateau at the western edge of our forecast area. Rain showers are still developing along, ahead of and behind this boundary. Thunderstorms and heavy rain have moved out of the region. The highest rainfall amounts have been south of I-40 with many locations receiving one to two inches. North of I-40, rain amounts have been much lower with most locations receiving less than half an inch.

Light to moderate rain showers will continue overnight. The highest rain amounts are expected over the Southern Tennessee Valley and Southwest North Carolina with half an inch to one inch additional rainfall expected through the morning hours. The severe storm threat has ended. Instability has eroded from multiple rounds of rain. The flooding threat peaked in the evening hours and has been declining. I can't completely rule out some flooding issues in the southernmost counties as repeated showers and storms will continue until the front moves through but that area seems to be doing well with the rain due to the drought conditions and rain rates haven't been too high. The cold front will move through the region by morning.

Showers will linger this morning as the front is still slow to move and will likely be just south of the region. Showers will be light and spotty with a much drier air mass moving in with dew points in the 50s. By Thursday afternoon, a shortwave will move through the Tennessee Valley kicking the front out of the region. Most of the region will be dry through the afternoon hours. High pressure will be centered over the region Thursday night.

Friday night/Saturday morning another shortwave will move through the region but rain chances look low. A Gulf Low will bring rain chances to the Southeast Saturday/Sunday but the higher rain chances will likely stay south of the Tennessee Valley. Sunday and Sunday night will bring a better chance for showers and storms as a system with good upper level support moves through the region. Otherwise, early next week looks mostly dry. Highs will be mainly in the 70s.
