KEY MESSAGES

Issued at 649 PM CDT MON JUN 29 2026

- Hot and humid conditions will lead to elevated heat risk across Central Alabama through much of this week. A Heat Advisory is in effect from 11 am Monday through 9 pm Tuesday.

DISCUSSION

(This afternoon through Sunday) Issued at 125 PM CDT MON JUN 29 2026

Focus of this forecast will remain the heat and humidity, especially through the rest of the work week. Latest observations from reliable weather stations indicate heat indices around central Alabama are climbing above 100 degrees in many areas, with a few already around 105. Similar conditions (maybe a tick higher) are forecast for Tuesday. The Heat Advisory continues overnight and through tomorrow for all of central Alabama. Based on the latest forecast numbers for Wednesday, we've gone ahead and extended the Heat Advisory for the northwestern portion (along and north of a Sumter-Shelby-Cherokee County line) through 9 pm Wednesday.

The center of the big upper ridge responsible for the enhanced heat/humidity combo is forecast to push northeastward over the coming days, which will put us on the south side of the bubble. A tropical easterly flow, and a slight weakening of the subsidence associated with the upper high, will allow for diurnal thunderstorm development through the rest of the week. Best rain chances each day will largely be determined by mesoscale influences (previous days' leftover boundaries, cloudy/clear boundaries, elevated heat sources, etc.). POPs in the 20-30 percent range seem reasonable. As the ridge further breaks down over the weekend and early next week, then POPs are likely to inch up a bit more.

AVIATION

(00Z TAFS) Issued at 649 PM CDT MON JUN 29 2026

VFR conditions will persist overnight and into Tuesday morning. There may be a few locations that experience temporary reductions in visibility near sunrise, but confidence is too low to include at this time. Expect cumulus development to increase by late morning with chances for showers and some thunderstorms increasing from the southeast and moving west, with greatest potential to affect AUO and MGM through the midday and early to mid afternoon hours.

Note: AMD NOT SKED will continue for the AUO TAF until data issues with observations are resolved.

FIRE WEATHER

Rainfree conditions are expected through Monday. Slightly better diurnal convection chances are expected by Tuesday. Outside of pockets of rain, the primary story through this week will be the heat and humidity. Fire weather impacts are not anticipated as minimum relative humidity will remain well above critical values.
