| Area Forecast Discussion National Weather Service Mobile AL 1220pm CST Wednesday Feb 18 2026 Issued at 1045am CST Wednesday Feb 18 2026 A southwesterly flow aloft persists over the forecast region through Friday night while an upper trough advances across the western states and into the central states. The upper trough amplifies while continuing across the eastern states over the weekend into early next week, and in the process an associated surface low brings a strong cold front through the forecast area late Saturday afternoon into the evening hours. A persistent southerly flow ahead of the approaching front bring improving deep layer moisture into the area, along with a potential for nightly fog development. A series of shortwaves moving through the southwesterly flow aloft bring a small chance for rain to coastal and eastern portions of the area tonight and Thursday, with chance to likely probability of precipitation for Thursday night into Friday night. Have gone with mainly likely probability of precipitation for Saturday as the front approaches and moves into the area, then probability of precipitation taper off from west to east Saturday night followed by dry conditions on Sunday. Dry conditions continue for Monday into Wednesday. MLCAPE values increase to around 500 J/kg on Friday with potentially similar values continuing into Friday night, then values of 500-1000 J/kg look to develop ahead of the front on Saturday. Shear values look to remain on the low end through the period, and will continue to monitor at this point. Warm temperatures are expected prior to the front, with highs Thursday and Friday mostly in the upper 70s to lower 80s. Lows will be in the 60s. Much cooler air flows into the area in the wake of the front with lows Sunday night in the 30s, and in the mid 20s to mid 30s Monday night. Highs on Sunday will be in the upper 50s to lower 60s, and in the 50s on Monday. Highs recover to the upper 60s to lower 70s by Wednesday, with lows by Wednesday night trending to around 50 to the mid 50s. A low risk of rip currents is expected through tonight, with a moderate risk for Thursday through Sunday. /29 Marine Issued at 1045am CST Wednesday Feb 18 2026 A light to moderate onshore flow will continue through Saturday. A strong cold front moves through the area Saturday night, with a strong offshore flow developing in the wake of the front and persisting into Sunday night. Gusts to gale force are possible well offshore late Saturday night into Sunday night. A Small Craft Advisory will likely become necessary from Saturday night into Sunday night, and much of Monday as well. /29 NOAA Mobile AL Office: Watches - Warnings - Advisories AL...None. FL...None.
