KEY MESSAGES

Updated at 1100 AM CDT Tue Jun 9 2026

- Additional rain chances (40% or less) will linger through today with a low risk of flooding if storms track across previously flooded areas in northeast AL.

- Heat Risk increases by late this week with heat index values in the middle 90s to around 100 degrees Wednesday through Friday.

- Monitoring the risk for additional heavy rain and flooding early next week.

NEAR TERM

(Tonight) Issued at 326 PM CDT Tue Jun 9 2026

Mostly dry conditions have prevailed across the area this afternoon with the exception of a few short lived thunderstorms over DeKalb County. Current heat indices have risen to the 92-98 degree range making for an uncomfortably hot and humid afternoon. We will maintain low chances for rain and thunder through the afternoon across far north AL and southern middle TN. No significant changes were made during the afternoon update.

Previous discussion: With the upper wave responsible for yesterday's storms exiting to our east, there will be less support for convection locally and thus we have PoPs capped at 40% or lower across portions of northern/northeast AL and southern middle TN today. With still weak steering flow aloft, any showers or storms that do develop in the area will be slow moving and will have the potential for producing heavy rain. We will have to monitor the radar trends closely especially across areas that have experienced flooding this week.

Outside of this, highs will top out in the mid to upper 80s with humidity bringing heat indices to the mid to upper 90s. Please practice heat safety by protecting your skin, staying hydrated, and never leaving people or pets unattended in vehicles.

Overnight lows will fall to the upper 60s/lower 70s with chances for patchy dense fog especially across northeast AL. We will monitor this closely through the night in case Advisory conditions are met.

SHORT TERM

(Wednesday through Thursday) Issued at 326 PM CDT Tue Jun 9 2026

As sfc high pressure sits over the far SE, relatively drier air will move in at least temporarily through the mid-week period offering a trade off between the rainy pattern for a hotter and humid few days. Dangerous heat will be the main concern with highs in the low to mid 90s and heat indices near or just above 100 degrees. While we won't be completely rid of thunderstorm chances, they will be confined to areas in northeast AL and will be capped between 20-30% both days. With overnight lows in the low to mid 70s, this will offer little relief from the warm and humid conditions during the day. Please wear skin and heat protecting clothing if spending time outdoors as well as staying hydrated. Always look before you lock and never leave people or pets in unattended vehicles!

LONG TERM

(Thursday night through Monday) Issued at 956 PM CDT Mon Jun 8 2026

The aforementioned warming trend will continue through the early weekend, with highs reaching the mid 80s to low 90s Friday along with heat indices in the upper 90s to around 100-103 degrees. One thing to keep an eye on with Friday will be how much cloud cover and returning rain chances affect these forecast temperatures. There continues to be model uncertainty in how far south a cold front travels and subsequent rain chances on Friday. Heat continues through the weekend (although with lower heat index values) as highs warm into the mid 80s to low 90s both Saturday and Sunday. Despite this forecast remaining below Heat Advisory criteria, we reiterate to remain hydrated and take precautions to prevent heat related illness.

AVIATION

(18Z TAFS) Issued at 1256 PM CDT Tue Jun 9 2026

VFR conditions will persist through the TAF period with a low chance for showers and storms this afternoon as well as patchy fog overnight. Amendments may be needed if it looks like the terminals will be impacted.
