| Area Forecast Discussion National Weather Service Mobile AL 322am CDT Tuesday August 11 2026 ...New UPDAT Marine .KEY MESSAGES... Updated at 322am CDT Tuesday August 11 2026 - Heat indices around 100-107 degrees are expected today, increasing mid week on. - A Moderate risk of rip currents returns to Florida beaches Wednesday afternoon through Thursday. Issued at 309am CDT Tuesday August 11 2026 The 00z Rip Current Risk probability guidance is now showing a Moderate risk for the Florida beaches starting Wednesday afternoon where we expect slightly higher west-southwesterly winds and significant wave heights. This Moderate risk will continue through Thursday before settling back to Low. /22 Issued at 1204am CDT Tuesday August 11 2026 Through Thursday night, an upper level shortwave trough digging off the East Coast shifts an upper high over the northern Gulf Coast, westward, to over the northwestern Gulf Coast. A surface high over the eastern Gulf shifts west to over the central Gulf in response, with a drier airmass over the Gulf (precipitable h20 values less than 1.5") shifting north over the northern Gulf and Lower Mississippi River Valley. This displaces the moist airmass over the forecast area eastward to varying extents, depending upon the model. Add in an upper level shortwave trough passing over the northeast side of the upper ridge Wednesday, and a dry, subsidence caused day Tuesday sees isolated to scattered showers and thunderstorms over the eastern half of the forecast area Wednesday. Thursday, Probability of Precipitation drop to isolated, mainly over areas southeast of I-65 as moisture levels drop and upper subsidence returns and builds east a bit, even as the upper high shifts west. Temperatures see a bit of an increase with dropping moisture levels, especially over the western half of the forecast area along with upper subsidence increasing a bit with the building upper high. High temperatures away from the coast rise from the 92-97 degree range Tuesday rise into the 94 to 99 degree range Thursday. Along the coast, high temperatures around 90 are expected through mid week. Heat indices rise from the 100-107 degree range over most of the forecast area Tuesday rise into the 105 to 110 degree range Thursday. A Heat Advisory will likely be needed Wednesday, though the extent is hard to pin down at this time. Friday though the weekend, The upper ridge centered over the northwestern Gulf coast shifts north, to over the Southern/Central Plains, surface high pressure shifts to over the Southern Plains in response. As the upper high moves off over the central Conus, increased moisture over the eastern half of the Southeast shifts west over the region (and the forecast area), but an upper building east over the Southeast will keep good upper subsidence over the region, helping to limit Probability of Precipitation to isolated to low end scattered at best over the forecast area into the coming week. Temperatures see a small uptick into the weekend, along with Heat Indices.. Taking a look at the Rip Current risk on area beaches, a general Low Risk is expected into mid week, with the onshore flow less organized. An uptick to a low Moderate is indicated for the end of the week, especially over our Florida beaches. /16 Marine Issued at 322am CDT Tuesday August 11 2026 Light southwesterly to westerly winds will occur tonight through the remainder of the week as a surface high pressure area remains across the eastern Gulf. /22.
