KEY MESSAGES

Updated at 128 AM EDT Tue Apr 14 2026

- A warming trend with above normal temperatures expected through this week. Record highs are possible.

- There is very limited chances for light rain through the forecast period. This will result in worsening drought and fire weather conditions.

DISCUSSION

Issued at 121 PM EDT Mon Apr 13 2026

A large high pressure ridge will remain over FL/Gulf/western Atlantic through this forecast period, which will provide above normal temperatures and generally dry conditions to the Southern Appalachians and TN Valley.

We are seeing a good amount of cloud cover today from a jet streak and shortwave trough passing by to our north, but once that passes to our east tonight, mostly sunny clear will return. High temps tomorrow will approach records for the date, with the same expected on Wednesday. Low RH values will be of concern for fire weather interests, bottoming out in the 25-35% range both days for most locations, but thankfully the SW winds will be mainly in the 5-15 mph range. With these lighter winds, we do not anticipate the need for any Fire Danger statements over the next few days.

Models show the ridge drifting southward a bit on Thursday, allowing a mid/upper level trough and jet streak to cross the region. NBM has been trending higher with rain chances, which are now in the chance range north of I-40 Thursday afternoon and evening. Looking at the NAM forecast soundings Thursday afternoon, there is a strong stable and dry layer that will have to be overcome for any measurable precip, leading to skepticism of the NBM PoPs. Don't get your hopes up for any meaningful rainfall just yet. Highs will be pushing near records again on Friday and Saturday as the ridge amplifies northward again. Better rain chances may exist on Sunday as models show a deeper trough developing over the Plains that could push a cold front through our area.
