KEY MESSAGES

Updated at 956 PM CDT Mon Jun 8 2026

- Additional rain chances (40% or less) will return Tuesday morning, bringing a low risk of flooding issues

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

NEAR TERM

(Rest of tonight and Tuesday) Issued at 956 PM CDT Mon Jun 8 2026

Most of the rain has pushed eastward out of the area with only a few areas of lingering flooding continuing in NE AL. Mostly dry conditions are forecast overnight and skies have already begun to clear in NW AL on recent satellite imagery. CAMs are trending towards mostly clear skies overnight along with light winds, which should set us up for patchy to dense fog throughout the area. While confidence is not high enough to go with a Dense Fog Advisory at this time, there is a low-medium chance one could be issued during the overnight hours. Use caution on the morning commute as visibilities may be limited. Any fog that does form should begin to dissipate during the mid morning hours. An upper level shortwave trough axis should continue to creep eastward and bring low chances of rainfall back into the area by the morning hours (primarily north of the TN River).

SHORT TERM

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

As the aforementioned trough axis shifts eastward through the area, low chances of showers/thunderstorms return primarily north of the TN River through tomorrow afternoon. Trends in recent models have shown a drier forecast, which is why we've allowed the Flood Watch to expire and currently do not anticipate the need for another one. That being said, a low risk of flooding does remain if any heavy rainfall is able to materialize tomorrow (especially in NE AL where antecedent rainfall has caused very saturated soils). In this area, the Weather Prediction Center has continued to hold a Slight risk (level 2 of 4) for excessive rainfall causing flash flooding on Tuesday. By Tuesday evening, upper level ridging begins to creep into the area from the west and rain chances subside from west to east. Mostly dry conditions are forecast Wednesday and Thursday, with low chances (30% or less) of rain limited to NE AL and portions of southern middle TN as a frontal boundary stalls in the Appalachian region.

As the upper level ridge shifts over the area, a warming trend will begin with highs reaching the upper 80s to mid 90s by Thursday. Heat indices during this time are forecast to reach the mid 90s to around 100 degrees. Overall, our Heat Risk is forecast to push into moderate to major impacts, which will affect those who are sensitive to heat as well as anyone without cooling/hydration. We continue to urge everyone to remain hydrated, avoid outdoor labor during the hottest part of the day (if possible), and wear lightweight/cool layers. Additionally, avoid leaving any pets or people in 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

(06Z TAFS) Issued at 153 AM CDT Tue Jun 9 2026

A gradual increase in the coverage of mid/high-lvl cloudiness is expected at the HSV/MSL terminals early this morning as developing NW flow aloft spreads debris clouds southeastward from convection across Middle TN. Although this may inhibit the development of locally dense fog in an otherwise favorable environment, we will include a TEMPO group for MVFR vsby reductions for the next few hours. Otherwise, conditions will remain VFR (at least until potential redevelopment of BR/FG late Tue evening). A few SHRA/TSRA may occur this aftn region-wide, but chances for direct impacts at either terminal are too low to include in the official TAFs. Sfc winds will range from SSE-SSW, with prevailing speeds of 5-10 kts.
