DISCUSSION

Issued at 142 PM EDT Thu Apr 2 2026

Currently another very warm April day, likely to be the warmest day of this 7-day forecast as temperatures are in the 80's early this afternoon across much of the eastern Tennessee Valley. Satellite imagery shows some cumulus forming along the higher terrain and some of this could bubble up enough to cause brief, very isolated, showers or thunderstorms mainly across the higher elevation. Can't rule out a rogue shower dropping down into the valley, but for the vast majority of the population, today will be another sunny and warm day.

Warm temperatures continue tomorrow, but should be a few degrees lower as there's a bit more cloud coverage with a shortwave moving through the northern US.

We'll get a cool down this weekend when a trough moves through the Northern Plains into the Great Lakes Region. At the same time a low pressure center near the central US will also track towards the Great Lakes. This will drag along with it a cold front that should sweep through the eastern Tennessee Valley Saturday night into early Sunday. This will be our best chance for widespread precipitation over the next 7-days which is definitely needed with the ongoing drought conditions across the southeastern United States. Some locations could see up to or just over one inch of rainfall. There look to be some decent dynamics in this system, and we can't rule out seeing strong to severe thunderstorms. If we end up getting the 1+ inches of rain this could lead to brief isolated flooding of low lying and urban areas during the time of heaviest rainfall. But with the river and lake levels lower than normal... River flooding is not anticipated at this time.

Following the front, cooler more seasonable temperatures are expected Sunday into next week. A dry few days may set in with low afternoon RHs, which could bring back fire weather conditions. Frost development may even be possible some mornings early next week behind the front as a second cold front Tuesday/Wednesday may bring even colder temperatures to the area Wednesday morning.
