| Area Forecast Discussion National Weather Service Mobile AL 402pm CDT Sat April 27 2024 ...New NEAR TERM, SHORT TERM, LONG TER Marine Near Term (Now through Sunday) Issued at 402pm CDT Sat April 27 2024 An upper level ridge will remain in place along the Southeastern Seaboard through the weekend as an upper low pivots across the central US. This pattern will result in a southwesterly flow aloft over the local area. Down at the surface, a tight pressure gradient has developed in response to a surface high pressure along the east coast/western Atlantic and an area of surface low pressure over the Plains. This pressure gradient has resulted in breezy southeasterly winds today with gusts up to 30-35 mph being reported at times. Winds are expected to ease slightly overnight with breezy conditions re-developing especially near to the coast on Sunday. Given the lack of appreciable forcing and deep layer moisture, conditions are expected to remain dry through most of the period. The exception to this will be on Sunday over parts of southeast Mississippi where weak isentropic ascent could lead to an isolated shower or storm. Hi-res guidance continues to indicate this potential so have maintained the 15-20% Probability of Precipitation forecast over southeast Mississippi for Sunday afternoon. Otherwise, expect to see very similar conditions continue on Sunday with another decent cumulus field and passing mid/upper level clouds resulting in partly cloudy skies. Beach Note: Persistent onshore flow will result in deadly rip currents and increased surf heigheights along all area beaches through the weekend. Local lifeguards reported flying red and double red beach warning flags today, meaning that the Gulf Waters are closed to the public. The HIGH risk of rip currents remains in effect through the weekend and into early next week. A High Surf Advisory also remains in effect through Monday for large breaking waves of 4- 6 feet at all area beaches and possibly even up to 7 feet on Sunday for portions of the western Florida panhandle. /14 .SHORT AND Long Term (Sunday night through Saturday) Issued at 402pm CDT Sat April 27 2024 An upper ridge over the eastern CONUS deamplifies and shifts eastward into Monday followed by the base of an upper shortwave passing over the region Monday afternoon into Tuesday. An upper ridge rebuilds a bit over the Southeast midweek, with a second upper shortwave passing over the region late in the week. A surface ridge extending from the Atlantic westward across the region will remain persistent, maintaining a slight southerly surface wind across the forecast area throughout the week. The highest precipitable H20 values should occur Monday afternoon and evening (1.5"-1.8") and from the mid/late part of the week. Best combination of moisture and decreased subsidence remains west of the forecast area Monday into Monday night, and with that, best chance of rain is expected to be along and west of the Alabama River. Rain chances shift east for Tuesday as the tongue of moisture shifts east. Guidance indicates enough instability with SBCapes rising into the 800-1200J/kg range along and west of the Alabama on Monday, and into the 1000-2000J/kg range on Tuesday to include a chance of thunderstorms eastward over the entire forecast area. Wind shear remains limited with the shifting of the surface ridge helping to keep wind shear low, so am expecting the chance of organized strong to severe storms to be low. Temperatures are expected to remain above seasonal norms, with subsidence from the eastern upper ridge remaining strong enough over the Southeast. High temperatures in the mid to at times upper 80s are expected over inland areas, around 80 along the coast. Low temperatures are expected to range from around 60 over central Alabama to mid to upper 60s over portions of inland southeast Mississippi and along the coast. /22 Marine Issued at 402pm CDT Sat April 27 2024 A Small Craft Advisory remains in effect for much of the marine area through late Sunday night for southeasterly winds averaging between 15-25 kts and frequent gusts up to around 30 kt possible. Seas are also expected to build up to 6-8 feet offshore during this time. Southeasterly winds gradually diminish with subsiding seas during the early to middle part of the upcoming week. /14 NOAA Mobile AL Office: Watches - Warnings - Advisories AL...High Rip Current Risk through late Tuesday night for ALZ265-266.
