DISCUSSION

Issued at 1215 AM EST Sat Feb 28 2026

Pleasant weekend weather continues today and tomorrow with plenty of sun, mostly clear skies, and light winds in place. Very weak frontal boundary continues to meander just north of the Tennessee Valley. This will make a push southward heading into next week. A weak disturbance will ride north of this boundary within the broader troughing in the mid/upper levels. This will bring our next chance of precipitation to the region. Current location of the better synoptic energy is north of Interstate 40, but even these locations aren't expected to see too much precipitation. Northeast TN into southwest VA could see a couple of tenths of precipitation on Monday, but with the weak energy in this system still expecting all rain, and no thunderstorms.

Biggest weather story of next week will be the rapid warming with highs possibly eclipsing the 80 degree mark in southeast TN on Friday. There will be a battle ground next week between the strong ridge over the southeast and a few low pressure systems moving out of the west. Currently looks like this will result in lots of rain over the Mississippi Valley into the western Tennessee Valley, but worth keeping an eye on because if these systems shift eastward we'll get more chances for rain. So while we have precipitation chances increasing over the weekend, at this time, it looks to be more showery instead of widespread rain further to our west.

However we do feel much more confident on the warm temperatures for the end of the week as the ridge strengthens. The specific temperatures can and likely will change as we get closer, but as of right now the forecast is within a handful of degrees of record highs in some spots.
