DISCUSSION

Issued at 214 AM EDT Fri Apr 3 2026

In the upper levels, a ridge is over the Southeast and Mid-Atlantic. A shortwave is moving through the Midwest into the Great Lakes currently. At the surface, a low is moving into the Great Lakes tonight but that cold front will stay well to our north with ridging and high pressure over the Southeast and Mid-Atlantic. Radar will remain quiet tonight although a spotty shower in the Cumberland Plateau cannot be ruled out. This afternoon shower and storm activity will be isolated and confined mainly to Northeast Tennessee. Temps will still be warm today with highs in the lower 80s in the TN Valley. A smidge more cloud cover is likely today.

Tomorrow afternoon, showers and storms will be more scattered as the ridge starts to break down. Saturday night into Sunday morning, widespread showers and storms are expected as a cold front moves through. This system will have good upper level support with a trough making it into the Southeast. At the surface, the parent low will move through the Great Lakes bringing a cold front through the region by Sunday morning. A few strong storms cannot be ruled out but instability looks very low with storm timing late in the evening or overnight. Dew points will only get into the lower 60s in the Tennessee Valley. Much of the region will get a much needed rain with forecast rain totals around one inch.

Rain will start to taper off Sunday morning as a much cooler air mass moves into the region. Highs from Sunday through midweek will be closer to seasonal normals in the 60s. Much cooler than recent weather. Frost will be a concern Monday through Wednesday mornings especially for the northern half of the region and the mountains. Dry weather will continue through midweek.
