KEY MESSAGES

Updated at 939 PM CDT Mon Jun 22 2026

- After a period of drier conditions Tuesday into Wednesday morning, chances for showers and storms increase to 40-60% from Wednesday afternoon into Thursday.

- Elevated heat concerns will return late this week as heat index values rise into the 95 to 103 degrees Friday through Monday.

NEAR TERM

(Today) Issued at 322 AM CDT Tue Jun 23 2026

Low clouds continue to remain entrenched over northern Alabama and southern middle Tennessee this morning. Temperatures should be cooler when you wake up this morning, dropping into the lower to mid 60s. Expect cloudy conditions to linger until around noon before breaking up. Sunshine this afternoon with weak cold air advection will push highs into the the upper 70s to lower 80s. So, thankfully a nice day after the inclement weather yesterday.

SHORT TERM

(Tuesday night through Thursday) Issued at 945 PM CDT Mon Jun 22 2026

We remain in a somewhat active pattern Wednesday and Thursday as a couple of shortwaves clip the Tennessee Valley, bringing low to medium (20-40%) chances for showers and a few thunderstorms Wednesday and Wednesday night. On Thursday, an additional shortwave will interact with a weak front that will move northward into the area. This will create medium chances (40-60%) for showers and thunderstorms during the afternoon/evening hours. In addition to the thunderstorm chances, temperatures will be on the rise, with highs in the mid to upper and heat index values in the mid to upper 90s. Those with outdoor plans should continue to monitor the forecast and follow common sense heat safety practices.

LONG TERM

(Thursday night through Monday) Issued at 945 PM CDT Mon Jun 22 2026

The primary concern for the long term period is heat. As an upper level ridge shifts eastward into the area along with sfc high pressure over the Gulf, a warming pattern will take shape through the weekend with highs reaching the upper 80s to lower 90s (with some spots in the mid 90s on Monday). These temperatures are near normal for this time of year, however, overnight lows will be ~5 degrees above normal with temperatures dropping into the low to mid 70s. Heat index temperatures are forecast to reach the upper 90s to around 103 degrees. We will also be monitoring Heat Index values Monday, especially, as we near criteria for a Heat Advisory. NWS HeatRisk highlights the area in a Moderate to Major risk, which means heat will likely affect anyone sensitive to heat (especially those without adequate cooling/hydration) as well as some health systems and industries. If you have outdoor plans this weekend, be sure to practice heat safety such as staying hydrated and seeking shade when outdoors to avoid heat related illness.

AVIATION

(12Z TAFS) Issued at 615 AM CDT Tue Jun 23 2026

MVFR CIGS should continue at both terminals into the morning hours. At KMSL, winds should be lighter through 15Z (around 4 knots..maybe less). However, clouds should keep fog from forming. Winds should remain higher at KHSV more from the NW as well through 15Z. Then expect winds to pick up and become more northerly between 5 and 10 knots with gusts between 10 and 15 knots. Around 17Z, expect MVFR CIGS to break up and VFR conditions to return with some sunshine. Light and variable winds are expected after 24/00Z. Fog development will have to be watched later tonight.
