KEY MESSAGES

Issued at 624 PM CDT THU JUL 23 2026

- Heavy Rain: A stalled cold front combined with Gulf moisture will bring potential for heavy rainfall through the weekend. A Flood Watch remains in effect through Saturday morning.

- Heat: Intense heat returns early next week. Expect temperatures in the upper 90s to near 100 from Monday through mid-week, with heat indices reaching or exceeding 105 degrees.

DISCUSSION

(This afternoon through Wednesday) Issued at 229 PM CDT THU JUL 23 2026

Guidance and NHC continue to keep Tropical Storm Bertha moving westward away from Alabama toward the Southeast Texas Coast tonight. Meanwhile, a quasi-stationary front continues to meander across the Southeast and Tennessee Valley, tapping into deep tropical moisture to support widespread, heavy showers and thunderstorms. This pattern sustains an ongoing risk for high rain rates and flash flooding across the region through Friday and into Saturday, with training convective clusters remaining a primary concern where precipitable water values exceed 2 inches.

For Central Alabama, this stalled boundary maintains an unsettled, wet regime through early Saturday, with a Flood Watch persisting for far northeast counties. While widespread cloud cover and rain will suppress temperatures through the weekend, a significant pattern shift arrives next week. As an upper-level ridge expands across the South-Central U.S. and into the Southeast, temperatures will trend significantly hotter, introducing the potential for Moderate to Major HeatRisk by Monday and likely persisting into mid-week.
