...New AVIATION...
.SHORT TERM... (This evening through Saturday) Issued at 1204 PM CDT FRI SEP 5 2025
Surface analysis depicts a cold front to our northwest, extending from North Texas through the Ohio Valley. This boundary will push southeast through the day, moving into Central Alabama overnight into Saturday morning. Moisture pooling across the region will allow for showers and thunderstorms to develop along and ahead of this boundary. Greatest chances (30-50%) tonight and Saturday morning will be across our northern areas with the threat extending further south through the day Saturday. Much of this activity will be east of us by the evening hours. However, we could see a few lingering showers through the evening as moisture remains elevated and a trailing H85 vort max swings through. The much drier air arrives through the day Sunday as the H85 front passes through.
We will have one last hot day today with highs climbing into the mid 90s for most. We knock off a handful of degrees tomorrow with highs in the 80s. A few may not get out of the 70s across our northwest areas...depending on how fast the front arrives.

.LONG TERM... (Saturday night through next Thursday) Issued at 1204 PM CDT FRI SEP 5 2025
No significant changes needed with this long term forecast update. Drier air in place behind tomorrow`s cold front will leave us "cooler" through the week with highs generally in the 80s with lows in the 60s. We could see a isolated shower or two across our southeastern areas next week as moisture begins to return. However, without much forcing, not expecting too much activity.

Previous long-term discussion: (Saturday night through next Thursday) Issued at 1223 AM CDT FRI SEP 5 2025
The extended will be mostly warm and dry across Central Alabama during the afternoons, with highs in the mid to upper 80s through Thursday. Lows will be a refreshing upper 50s to mid 60s, depending on location. Some rain and storms appear to be possible across the far southeast, south of I-85, at least a couple days during the week. However, confidence on the northward extent of this is currently low, as most activity will be closer to the Gulf Coast. For now, no rain chances are mentioned in the forecast for any of Central Alabama from Sunday through Thursday. 12

.AVIATION... (00Z TAFS) Issued at 633 PM CDT FRI SEP 5 2025
A cold front will move into the area during this TAF cycle, bringing 1 to 2 rounds of at least scattered showers and storms. The first (lower confidence) round may impact the northern terminals between ~5z and ~10z. The second round has somewhat higher confidence but still not enough to include more than a PROB30 mention. This round will generally be between 15z and 00z Saturday, earlier for the northern terminals and later for the southern terminals. There are also medium chances for MVFR cigs around mid-morning at the northern terminals. Winds will become northwesterly around 6-8kts as the front passes.

.FIRE WEATHER...
Min RH values will range from 35-45% this afternoon and 40-55% Saturday afternoon across Central Alabama, with chances for isolated to scattered showers across the area through this afternoon. Rain chances increase tonight through Saturday afternoon, especially across northern and central counties. Behind the front, min RHs through the week will be as low as 35%, with a drier airmass working in. While no critical thresholds will be met, the area will be dry from Sunday through Thursday, potentially increasing fire concerns in that aspect, especially in areas that receive little to no rain this weekend.
