| Area Forecast Discussion National Weather Service Mobile AL 1138pm CST Fri Feb 20 2026 Issued at 1049pm CST Fri Feb 20 2026 As we head through the rest of tonight into the early morning hours the primary forecast headache will be the evolution of dense marine fog. A dense fog advisory has been issued for southern Mobile Bay and the Mississippi Sound through 6am this morning. It's possible this spreads in areal coverage, potentially impacting some of the adjacent land areas, however confidence on the coverage and density precludes issuing any dense fog advisories for coastal portions of Mobile and Baldwin counties at this time. Observational trends will continue to be monitored through the night. A strong cold front pushes across the area late this evening into tonight. Ahead of it, warm, moist air will continue to foster scattered to numerous showers and thunderstorms late this morning into early this evening. Ahead of the front, a few strong to severe storms can't be ruled out with a primarily damaging wind and large hail threat. Best chances will be along and east of the I-65 corridor in south-central Alabama and the Florida Panhandle. This is where instability approaching 1,500 to 2,000j/kg overlaps with 50 knots of deep layer shear and subtle forcing. The main limiter overall remains the forcing across the area, keeping the threat marginal. In the wake of the front it turns very cold, a stark contrast to the all time record warm day for February we just had. Highs plummet into the 40's and 50's by Monday, with overnight lows in the upper 20's and lower 30's Sunday night and middle to upper 20's areawide Monday night. We quickly modulate back into the lower 70's for highs by Wednesday and lows into the 50's by Wednesday night. Rain chances enter the picture again Thursday as another system moves across the area. Based on rip current reports from earlier in the day and the expectation for slightly stronger rip currents through Saturday night have opted to go forth with upgrading the moderate risk to a High risk of rip currents for our Alabama and Florida Panhandle beaches through daybreak Sunday. Rip currents gradually diminish with a Moderate risk for Sunday and a Low risk following for Sunday night into early next week. MM/25 Marine Issued at 1049pm CST Fri Feb 20 2026 A light to moderate onshore flow will continue today with dense marine fog possible this morning over southern Mobile Bay and Mississippi Sound. A strong cold front moves through the area to night, with a strong offshore flow developing in the wake of the front. Frequent gusts to gale force are expected late Saturday night into late Sunday morning. A Gale Warning will go into effect for this period for much of the marine waters. A Small Craft Advisory will continue afterwards through at least Monday afternoon, potentially needing extended for portions of the marine waters through Monday night. Offshore flow diminishes late Monday night into Tuesday morning. MM/25 NOAA Mobile AL Office: Watches - Warnings - Advisories AL...High Rip Current Risk through late Saturday night for ALZ265-266. FL...High Rip Current Risk through late Saturday night for FLZ202-204- 206. MS...None. GM...Gale Warning from midnight Saturday night to noon CST Sunday for GMZ630>632-650-655-670-675. Small Craft Advisory from noon Sunday to noon CST Monday for GMZ630>632-650-655-670-675. Dense Fog Advisory until 6am CST Saturday for GMZ631-632.
