FXUS64 KHUN 221933 AFDHUN Area Forecast Discussion National Weather Service Huntsville AL 233 PM CDT Sat Aug 22 2026 ...New NEAR TERM... .KEY MESSAGES... Updated at 909 AM CDT Sat Aug 22 2026 - A few thunderstorms may impact the western portion of north AL late this afternoon/early this evening. Brief strong wind gusts could accompany the most intense cells. - There are low to medium chances of thunderstorms for much of next week. However, timing and impact confidence remains low at this time. && .NEAR TERM... (Tonight) Issued at 233 PM CDT Sat Aug 22 2026 Under mostly sunny skies temps have warmed into the high 80s to low 90s. Relatively benign weather is forecast through the early afternoon, after which, attention will shift to a cold front approaching from the NW. Currently, a complex of storms can be seen moving SE through the Ozarks. As the cold front continues to drop SE, storms too will move gradually SE. Still thinking storms will arrive between 6-8 PM and push through by midnight. Unfortunately coverage remains fairly uncertain as CAMS struggle to resolve the weak cold front and associated mid level shortwave. While coverage could be a little more widespread, the current forecast is that storms will clip NW AL, largely staying west of I-65. Storms that do develop will have a risk for damaging winds with bulk shear of around 30 KTs present along the front. Instability will be waning as storms move in, which will likely lead to a weakening trend as storms push south. Please check back for updates. Any storms and rain present look to end after midnight with clear conditions building in by morning. && .SHORT TERM... (Sunday through Tuesday) Issued at 909 AM CDT Sat Aug 22 2026 The short term forecast will have two features of interest. The first is slightly cooler temps with highs and lows a degree or two below seasonal norms. Highs look to largely remain below 90 degrees with lows staying below 70. The second feature of interest will be the overall synoptic pattern, which will remain in a ridging west / troughing east regime. This will keep us in NW flow and support additional shortwaves passing through the TN Valley. The first of these looks to be from Monday to Tuesday. While it's a little too soon to pull out specific details, really any passing feature could be enough to support general summertime thunderstorms each afternoon. Please check back for updates regarding any specific hazards and timing. && .LONG TERM... (Monday night through Friday) Issued at 751 PM CDT Fri Aug 21 2026 In the extended forecast, we will get a break from the extreme heat conditions, however in exchange for that, we will be stuck in an unsettled pattern. We will start off with the pattern of an upper level low up in Quebec and the far NE U.S with an amplified ridge stretching from the southern Rockies up through the Northern Plains. On the back side of the ridge, a smaller upper-level low in Manitoba will try to be the driving force for a pattern change. As that smaller low slides SE into the Upper Great Lakes mid-week, the ridge will be dampened enough for it to round the ridge. This pattern will keep us in a northwesterly flow through the week. Embedded in this flow will be shortwaves that will swing through the TN Valley, keeping daily rain chances in. Right now it looks like there is a chance for an MCS to drop through on Tuesday, then again Wednesday night into Thursday morning. Will keep an eye on trends for specific hazards and timing, but for now will stick with NBM POPs. Daytime highs will be in the upper 80s to lower 90s with overnight lows around 70 degrees. && .AVIATION... (18Z TAFS) Issued at 1153 AM CDT Sat Aug 22 2026 VFR conditions are largely expected through the TAF period. A low chance for showers and storms exists this evening at MSL from around 23Z-02Z. Have not included anything in the TAF due to low confidence but amendments may be necessary if storms do make it this far east. Any flight restrictions should lift back to VFR by 06Z and prevail through the remainder of the period. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...None.
