| Area Forecast Discussion National Weather Service Mobile AL 1238am CST Sunday Nov 9 2025 Issued at 1228am CST Sunday Nov 9 2025 An anomalously strong longwave trough is expected to dig into the eastern US over the next 24 to 48 hours. This will help to push a potent cold front through the local area this afternoon, allowing for the first arctic airmass of the season to filter through the Deep South and into the Gulf. For the remainder of the overnight and into the morning hours, weak moisture pooling, limited forcing, and some elevated instability may allow for a few showers or possibly a thunderstorm, to develop ahead of the front (rain chances around 20-30%). Once the front passes, rain chances drop to zero as much colder and drier air will advect in from the northwest. Given the strong gradient, winds behind the front will also be on the increase, with gusts this afternoon potentially as high as 25- 30mph in spots. Highs today will range from the upper 60s to low 70s west of I-65 to the mid to upper 70s for areas east, but with the progression of the front, these highs will likely occur during the mid to late morning hours, with temps lowering throughout the afternoon. Bitter cold temperatures/wind chills are expected across the area from Sunday night through Tuesday night. Lows Sunday night will likely drop into the 30s areawide, with maybe a few locations along the immediate coast staying in the low 40s. Winds will remain rather gusty Sunday night, which should keep our area just above the freezing mark (with the exception of a few localized areas in our far northern counties). However, factoring in the wind chill, it will likely feel like the mid to upper 20s for most of the area, and low 30s along the coast. For Monday, even under sunny skies, the continued gusty winds/strong cold air advection will likely keep highs in the upper 40s to low 50s. By Monday evening and into Monday night, winds will finally begin to relax as high pressure moves overhead. Light winds, dry conditions, and clear skies, will lead to efficient radiational cooling, likely causing temperatures to plummet into the 20s for areas north of I-10. Even areas south of I-10 may also drop to below freezing. In fact, NBM probabilities for lows less than 32 degrees have increased even further during the latest run, ranging now from 50-70% along the coast. Therefore, it is looking increasingly likely that a Freeze Watch will need to be issued for the entire CWA (County Warning Area) in the next forecast package. Daily record lows are also in jeopardy of being broken at our local climate sites (KMOB record: 31 degrees; KPNS record: 33 degrees), with the NBM giving a greater than 75% probability of each location breaking their respective records. Additionally, although winds are expected to be light Monday night, there may be enough of a wind chill factor to support the need for a Cold Weather Advisory for apparent temperatures dropping into the upper teens to low 20s. Reiterating what the previous shift stated, given the relatively abrupt and early nature of this cold compared to normal, as well as the fact that we were recently in the 70s and 80s, we are not yet acclimated to this degree of cold weather, which could lead to a more dangerous risk for vulnerable communities. We urge residents and visitors to make preparations to protect people, plants, pets, and pipes from this cold weather. After one more day of chilly temperatures on Tuesday, with highs in the 50s and lows ranging from the mid 30s inland to the low 40s along the coast, the high will shift to our east, allowing for winds to turn onshore. Although we remain dry through the remainder of the extended period, temperatures will rise back to above seasonal norms. Highs for late week will top out in the low to mid 70s and lows will range from the mid 40s inland to mid 50s along the coast. A Low Risk of rip currents remains in place through the period. /96 Marine Issued at 1228am CST Sunday Nov 9 2025 Moderate southwesterly to westerly winds this morning will become a strong northwesterly flow by the late afternoon hours in the wake of a strong cold front and will persist through Monday night. A Small Craft Advisory is in effect from this afternoon through Monday night for all local marine zones. Occasional gusts to gale force are possible over the open Gulf waters Sunday night into Monday morning. Winds will then relax on Tuesday and become a light onshore flow by Wednesday. /96 Fire Weather Issued at 1228pm CST Sunday Nov 9 2025 Given our longstanding drought conditions across the area and a rather dry frontal passage on Sunday, we have increasing concerns for dangerous burning conditions across the local area on Monday. Winds increasing to 15 to 20 mph with gusts nearing 30 mph during the day on Monday coupled with afternoon relative humidity values in the low to mid 20s will likely result in rather dangerous fire conditions. A Red Flag Warning may become necessary given the dry fuels across the area. Winds will subside on Tuesday; however, continued dry conditions could remain across the area leading to increased fire danger. /BB-8 /96 NOAA Mobile AL Office: Watches - Warnings - Advisories AL...None. FL...None. MS...None. GM...Small Craft Advisory from 3pm this afternoon to midnight CST Monday night for GMZ630>636.
