642 FXUS64 KMOB 010405 AFDMOB Area Forecast Discussion National Weather Service Mobile AL 1005 PM CST Sat Feb 28 2026 ...New UPDATE... .KEY MESSAGES... Issued at 952 PM CST Sat Feb 28 2026 - Dense fog is expected across far southeast Mississippi, coastal sections of Alabama and the western Florida Panhandle, along with south central Alabama mainly along and southeast of Interstate 65. - Above normal temperatures will continue through much of next week. && .UPDATE... Issued at 952 PM CST Sat Feb 28 2026 Surface high pressure centered over the forecast area has created ideal radiational cooling conditions as well as a favorable environment for the development of dense radiational fog. Dewpoint depressions (the difference between the temperature and dewpoint) continue to shrink and fog should begin developing over the next few hours. The most likely time period for dense fog over a widespread area will be after 3am through sunrise. Visibilities will likely drop to one quarter of a mile or less across areas covered by the dense fog advisory areas. Patchy fog, some which could be locally dense will be possible even in areas outside of the current advisory but should not be as impactful or widespread. The dense fog should extend into area bays and sounds along with the near coastal waters as weak offshore drainage flow will likely develop late tonight into Sunday morning. The highest potential will be Mobile Bay and portions of the Mississippi Sound. These areas will be slower to erode on Sunday morning due to the relatively colder water temperatures in place. Therefore the marine dense fog advisory extends through 11am across Mobile Bay and Mississippi Sound. The remainder of the forecast looks on track and no additional updates have been made this evening. Updated forecast products and hazards have been sent. /JLH && .DISCUSSION... Issued at 119 PM CST Sat Feb 28 2026 An upper level northwest flow will become zonal through Monday with upper ridging building across the area through the middle of next week. Light winds, clear skies and surface cooling will allow for another round of patchy dense fog late tonight. Otherwise, dry weather will prevail through the middle of the week. Above normal warm weather will be here to stay for the foreseeable future as highs stay in the middle to upper 70s this weekend before returning to lower and middle 80s for next week. Lows will be in the middle 40s to lower 50s this weekend before returning back to middle 50s to lower 60s mid to late next week. A Low risk of rip currents today will continue through Monday, becoming a High risk for strong rip currents once again Tuesday and at least a Moderate risk continuing into Wednesday. Rain chances increase late in the week as moisture returns to the area. /13 && .AVIATION... (00Z TAFS) Issued at 600 PM CST Sat Feb 28 2026 High pressure centered over the area will provide favorable radiational cooling conditions later tonight into early Sunday morning. This will likely support the reduction of dewpoint depressions and increasing fog potential. The most likely timing for fog development will be between after midnight through sunrise. The greatest threat for VLIFR visibilities and dense fog appears to be across coastal Alabama which includes KMOB and KBFM. There will also be dense fog potential at KPNS and KJKA, but the uncertainty at these sites remains higher at this time. Any fog that develops will gradually mix out Sunday morning with a return to VFR conditions for the remainder of the day Sunday. /JLH && .MARINE... Issued at 119 PM CST Sat Feb 28 2026 A light easterly to northeasterly flow today becomes easterly Sunday. Light to moderate easterly flow Monday becomes moderate to strong southeasterly flow late Monday night into Tuesday. Light to occasionally moderate southeasterly flow continues the rest of the week. /13 && .PRELIMINARY POINT TEMPS/POPS...
