KEY MESSAGES

Updated at 950 AM CDT Wed May 27 2026

- Medium to high chances (50-70%) for showers and storms exist across much of the TN Valley through the weekend.

- Drier conditions are expected by Monday/Tuesday of next week.

NEAR TERM

(Tonight) Issued at 255 PM CDT Wed May 27 2026

As expected, showers and thunderstorms blossomed across much of the area along and West of I-65 for the first part of the afternoon, with additional showers and storms approaching the area from the S across Central AL. This trend is expected to continue through the evening hours, and the current forecast handles this well.

Overnight lows will only fall into the 65-70F range with very humid conditions expected. Though clearing isn't expected overnight, low clouds will linger and should keep widespread fog production to remain patchy at best, but any additional clearing would allow for more widespread development.

SHORT TERM

(Thursday through Saturday) Issued at 950 AM CDT Wed May 27 2026

As alluded to above, the pattern won't change much through the remainder of the week, with daily chances for showers and storms each day. Slightly higher chances for convection exist this weekend (especially Saturday w/~80% PoPs) before a pattern shift occurs to start the new work week.

Thankfully, there's no strong signal for severe weather, but that said, a strong storm or two can't be ruled out that may produce 40mph winds and torrential rainfall during this time period. Daytime highs will be in the upper 70s/lower 80s each afternoon, with moist/soupy mornings in the middle/upper 60s to the lower 70s each day.

LONG TERM

(Friday night through Tuesday) Issued at 1036 PM CDT Tue May 26 2026

Ridging in the northern midwest will maintain a blocking pattern through the long term period. The placement of the ridge will allow several shortwaves to ride along its western periphery and drop SE into the TN Valley. At the surface, corresponding high pressure in the northern midwest will induce easterly flow along its base. This will maintain a muggy airmass as 60-70 degree dewpoints and elevated PWATS are pulled in from the Atlantic coast. All in all, the muggy airmass paired with several passing shortwaves will amount to additional days of medium to high rain chances of about 50-80% each afternoon. While thunder is likely with any showers, there are no strong signals for severe weather currently during this period. Rather, we will continue to monitor flooding potential. With high rain chances in place all week, additional rain in the long term may lead to compounding flooding concerns with any additional heavy rainfall increasing the chances of flash flooding and river flooding.

AVIATION

(00Z TAFS) Issued at 540 PM CDT Wed May 27 2026

Light to moderate showers will continue to move NE across the area through about 06Z. The chance of thunder is low with these however if a shower moves directly over the terminal, ceilings and visibilities could briefly lower. Around 09Z a low IFR to LIFR cloud deck looks to move into both terminals and remain through most of the morning. Conditions look to lift back to VFR around 16Z with additional low to medium chances of showers tomorrow afternoon. Subsequent TAF updates will refine shower chances and timing.
