KEY MESSAGES

Updated at 840 PM CDT Mon Aug 31 2026

- Hot and humid conditions to persist through next weekend, with Moderate to Major HeatRisk along with afternoon heat indices rising to between 100-106 degrees.

NEAR TERM

(Rest of tonight and Tuesday) Issued at 840 PM CDT Mon Aug 31 2026

The biggest feature of the near term will be the overnight lows. Under clear skies and calm winds, temps will drop to the low to mid 70s. These will be some of the coolest temperatures of the entire week so make sure to enjoy it no matter how muggy Tuesday morning feels.

Through the day on Tuesday high pressure both at the surface and aloft will promote clear skies and calm winds. Our mid level ridging will build slightly east, nearly centering us under the ridge. This will work to bump temperatures up a few degrees with highs breaking into the mid to high 90s. Despite the higher temps, dew points look to remain in the low 70s. This will work to keep heat indices slightly lower with most locations staying under 105F. Some urban locations may see 105F+ heat indices however this is not forecast to be widespread enough to warrant any heat product issuances. Nonetheless, heat will be a concern with or without heat headline so please make sure to continue to practice proper heat safety. Otherwise, as with the last few days, low chances for showers will again be forecast Tuesday afternoon across the area.

SHORT TERM

(Tuesday night through Thursday night) Issued at 840 PM CDT Mon Aug 31 2026

Through the short term period mid level ridging will continue to build over the TN Valley. This will continue our warming trend with highs in the upper 90s each afternoon. Without any prominent pattern changes dew points will remain unchanged with each afternoon seeing values in the low to mid 70s. While these lower dew points will keep us from widespread oppressive heat, heat indices do look to nudge over 105 by Thursday. There is currently uncertainty regarding how wide spread these values will be seen across the area, thus heat product decisions are likely still 24-48 hours out. Regardless of heat headline decisions, it will be important for those partaking in outdoor activities to continue to practice proper heat safety.

LONG TERM

(Friday through Monday) I issued at 840 PM CDT Mon Aug 31 2026

Not much change is expected in the overall weather pattern as we head through the long term period. Dangerous heat continues to be a threat through at least Sunday with Heat Risk forecast to remain at moderate (level 2 of 4) to major (level 3 of 4). The upper level ridge remains entrenched over the central and southeastern US with high pressure dominant underneath. As a result, hot and dry conditions continue through the weekend. While we cannot rule out a low (10-20%) chance of an isolated thunderstorm each afternoon, confidence is quite low in this occurring and most locations will likely remain dry. Afternoon highs each afternoon will rise into the mid to upper 90s with heat indices between 100-105F. The dome of high pressure begins to recede back to the west on Monday, which will provide some relief to the heat with afternoon highs only in the lower 90s. However, models continue to trend later with this occurring and it will be something we will watch as we get closer in time.
