| Area Forecast Discussion National Weather Service Mobile AL 1234am CDT Tuesday September 15 2026 Issued at 1140pm CDT Monday September 14 2026 An upper ridge over the region retreats from the area late this week and into Saturday as an upper low/trough forms over the far western Atlantic and advances into the northeast Gulf. A surface ridge builds into the southeastern states through midweek, setting up an easterly surface flow which ushers drier air into the forecast area. Isolated showers and storms will be possible over the coastal counties Tuesday afternoon with the seabreeze, but otherwise subsidence associated with the upper ridge will suppress convective development. The easterly surface flow with the building surface ridge strengthens mainly over the marine area Tuesday night into Wednesday, and isolated to scattered convection develops in response over the marine area which may affect mainly coastal portions of Alabama. Dry conditions otherwise prevail through Friday, then slight chance to chance probability of precipitation return to the forecast on Saturday as the upper low progresses into the northeastern Gulf along with a modest surface reflection trough and improving deep layer moisture. Chance to likely probability of precipitation follow for Sunday as the upper low looks to slowly progress a bit further across the Gulf along with deep layer moisture continuing to increase. A low risk of rip currents on Tuesday is expected to quickly increase to a High Risk for Wednesday and Thursday, then a moderate risk follows for Friday. As noted by the previous shift, will need to monitor surf heigheights which are expected to increase to 4-5 feet on Wednesday and Thursday. Should these increase further, then a High Surf Advisory would likely become necessary for these days. Heat index values of 100-107 are expected for Tuesday, but otherwise a combination of somewhat cooler daytime highs and/or lower surface dewpoints will limit heat index values. /29 Marine Issued at 1225am CDT Tuesday September 15 2026 Light to moderate easterly to southeasterly flow becomes established today, becoming strong Wednesday into Thursday. Winds relax to light to occasionally moderate easterlies to end the week. 1 foot seas today increase quickly Wednesday to 4 to 7 feet. A Small Craft Advisory remains in effect for the marine waters late Tuesday night through Thursday afternoon. MM/25 NOAA Mobile AL Office: Watches - Warnings - Advisories AL...None. FL...None.
