KEY MESSAGES

Updated at 939 PM CDT Mon Jun 22 2026

- After a period of drier conditions Tuesday into Wednesday morning, chances for showers and storms increase to 40-60% from Wednesday afternoon into Thursday.

- Elevated heat concerns will return late this week as heat index values rise into the 95 to 103 degrees Friday through Monday.

NEAR TERM

(Rest of tonight and Tuesday) Issued at 945 PM CDT Mon Jun 22 2026

After an active day of severe weather, a bulk of this activity has waned, with just a few clusters of showers and general thunderstorms over southern middle Tennessee and northeast Alabama. This activity will eventually dissipate after Midnight. However due to the moist boundary layer conditions and calm winds, patchy fog and/or low stratus may develop again in the predawn hours around daybreak. This fog will quickly dissipate by mid- morning and with some partial clearing, it should end up being a mostly sunny and fairly tranquil day across the region. In fact, with the boundary stalling south of the area, the forecast has trended much drier as a result, with PoPs generally around 5-10% in the afternoon.

SHORT TERM

(Tuesday night through Thursday) Issued at 945 PM CDT Mon Jun 22 2026

We remain in a somewhat active pattern Wednesday and Thursday as a couple of shortwaves clip the Tennessee Valley, bringing low to medium (20-40%) chances for showers and a few thunderstorms Wednesday and Wednesday night. On Thursday, an additional shortwave will interact with a weak front that will move northward into the area. This will create medium chances (40-60%) for showers and thunderstorms during the afternoon/evening hours. In addition to the thunderstorm chances, temperatures will be on the rise, with highs in the mid to upper and heat index values in the mid to upper 90s. Those with outdoor plans should continue to monitor the forecast and follow common sense heat safety practices.

LONG TERM

(Thursday night through Monday) Issued at 945 PM CDT Mon Jun 22 2026

The primary concern for the long term period is heat. As an upper level ridge shifts eastward into the area along with sfc high pressure over the Gulf, a warming pattern will take shape through the weekend with highs reaching the upper 80s to lower 90s (with some spots in the mid 90s on Monday). These temperatures are near normal for this time of year, however, overnight lows will be ~5 degrees above normal with temperatures dropping into the low to mid 70s. Heat index temperatures are forecast to reach the upper 90s to around 103 degrees. We will also be monitoring Heat Index values Monday, especially, as we near criteria for a Heat Advisory. NWS HeatRisk highlights the area in a Moderate to Major risk, which means heat will likely affect anyone sensitive to heat (especially those without adequate cooling/hydration) as well as some health systems and industries. If you have outdoor plans this weekend, be sure to practice heat safety such as staying hydrated and seeking shade when outdoors to avoid heat related illness.

AVIATION

(00Z TAFS) Issued at 621 PM CDT Mon Jun 22 2026

A brief lull in the action early this evening, with a return to VFR conditions in wake of the storms. Still have a TEMPO through 02-03z for MVFR conditions for a pulse TSRA that may redevelop during this window. Through 05-06z, additional -SHRA may redevelop as ceilings lower to MVFR levels. However, would expect precipitation to taper off late tonight, with MVFR conditions due to low stratus and light fog redeveloping early Tuesday morning. These clouds will then break up and a return to VFR conditions will occur late in the period.
