| Area Forecast Discussion National Weather Service Mobile AL 532am CST Fri Jan 9 2026 Issued at 1155pm CST Thu Jan 8 2026 A large upper trough mostly over the central portion of the CONUS slowly progresses into the eastern states through Saturday night then moves off into the western Atlantic Sunday night. A deep surface low lifts off to the Great Lakes region overnight and brings a trailing cold front to near the Mississippi/Ohio River confluence then over to near the Texas panhandle. In response to the slowly advancing large upper trough, a second surface low is expected to lift from near the lower Mississippi River valley Friday evening and into the northeast states, and in the process brings a cold front through the forecast area on Saturday. A series of shortwaves will move across the region mainly during the day on Friday into the evening before lifting off to the north. These shortwaves will lead to convection spreading into roughly the northwestern half of the forecast area Friday and persisting into the evening hours before starting to diminish as the shortwaves lift away from the area. While additional convection is expected to work across the area late Friday night into Saturday as the front approaches and moves through, the strength of the forcing with this convection looks weaker compared to Friday into the evening hours. Sufficient instability and shear and forcing will be in place to support a Slight Risk of severe storms mainly over southeast Mississippi and interior southwest Alabama generally from Friday into Friday night. A marginal risk of severe storms exists for much of the remainder of the area into Friday night, then across the entire area on Saturday. Another concern is the potential for locally heavy rainfall Friday into Friday night mainly across portions of southeastern Mississippi and southwestern Alabama. Considering dry antecedent conditions, will hold off on a Flash Flood Watch for this portion at this point and continue to reassess. Unseasonably warm temperatures continue until the frontal passage, after which cooler temperatures are expected with another cold front moving through Wednesday into Wednesday night. Lows Sunday night and Monday night tend to range from the mid/upper 20s inland to the lower/mid 30s near the coast, and highs will be in the 50s for Sunday through Tuesday. After a bit warmer temperatures on Wednesday, highs Thursday and Friday will again be mostly in the 50s. Lows Tuesday night and Wednesday night tend to range from the mid 30s inland to the lower 40s at the coast. Slight chance to chance probability of precipitation are expected Tuesday night into Wednesday night as the next front approaches and moves through, but despite the cool overnight temperatures, precipitation is expected to remain as rain. A moderate risk of rip currents is expected through Sunday, after which a low risk is anticipated through Tuesday. /29 Marine Issued at 1155pm CST Thu Jan 8 2026 Light to moderate southeasterly winds become southwesterly by Saturday morning. Dense marine fog is likely until mid Thursday morning mostly over the western Florida panhandle bays. A strong offshore flow develops Saturday night in the wake of a cold front, then diminishes on Monday. Gusts to gale force will be possible well offshore late Saturday night through Sunday night. A Small Craft Advisory will likely become necessary for most of the marine area from Saturday night until Monday morning. /29 NOAA Mobile AL Office: Watches - Warnings - Advisories AL...None. FL...None. MS...None. GM...Dense Fog Advisory until 9am CST this morning for GMZ634>636- 655. |
