KEY MESSAGES

Updated at 857 AM CDT Wed Aug 19 2026

- A very low risk of strong to severe storms exists this afternoon and evening.

- Strong to severe storms will be possible again tomorrow afternoon into the evening with slightly higher confidence in seeing strong to severe storms.

NEAR TERM

(Tonight) Issued at 151 PM CDT Wed Aug 19 2026

A weak complex of showers and a few thunderstorms can be seen on satellite and radar off to our north. This feature is not anticipated to have much of an effect on the local area aside from some additional associated cloud cover. Through the remainder of the afternoon there is a very low chance of showers and storms developing in NW AL, most CAMS keep us clear through the night. As such, we feel our Marginal Risk highlighted by SPC for damaging winds is unlikely to materialize this afternoon. Rather, complexes of showers and thunderstorms to our NW will continue to progress ESE through the evening and into the night. By the early morning hours, showers and perhaps a few thunderstorms may begin to tip over the TN/AL state line. Any showers or storms that are present early tomorrow morning will be sub severe. Additional cloud cover is also likely through the night and into the morning making for a perhaps more dreary start to our Thursday.

SHORT TERM

(Thursday through Saturday) Issued at 857 AM CDT Wed Aug 19 2026

Light showers and heavier cloud cover may be present Thursday morning north of the TN river as the storm system mentioned in the near term dies through the morning. Despite the slightly muggier start to the day, Thursday will again have a risk for strong to severe storms as a weak shortwave moves through the Mid MS Valley. SPC has again highlighted NW AL in a marginal for a risk of damaging winds with afternoon storms. CAMs are in okay agreement with storms initiating to our west and pushing east through NW AL. While we will have slightly more shear and forcing than today, damaging winds will remain our primary threat. The threat just may be a little bit more widespread with every storm posing a risk for strong to severe wind gusts. Timing wise the threat looks to follow our typically summer storms, popping up in the afternoon and dying off shortly after sunset. Please check back for updates.

Through the remainder of the short term forecast the CONUS will maintain a ridging west/troughing east setup. This will put us solidly in NW flow and promote slightly cooler temperatures (closer to seasonal norms) through the end of the week. Temps will fall into the low 90s with heat risk dropping to a level 1/4. this will be a much welcomed pattern after the heat the first half of August brought.

LONG TERM

(Friday night through Tuesday) Issued at 1006 PM CDT Tue Aug 18 2026

Dry conditions in the wake of the frontal boundary will prevail this weekend, which will be a far cry from this time last weekend when we saw Heat Advisory/Extreme Heat Warning criteria across the Southeast. Heat Index values this weekend won't even crack the century mark, topping out a few degrees on either side of 95F. Rain returns by Tuesday, but otherwise seasonable temperatures will prevail during this time with daytime highs in the lower 90s and morning lows in the middle 60s (with even a few pixels of lower 60s in sheltered valleys of NE AL)!

AVIATION

(18Z TAFS) Issued at 1143 AM CDT Wed Aug 19 2026

Light and variable winds will remain through the TAF period with VFR conditions likely the entire period. There is a low chance of some showers around 12Z tomorrow morning yet confidence is currently too low to include any mention of them at this time.

HUN WATCHES/WARNINGS/ADVISORIES
