Area Forecast Discussion National Weather Service Mobile AL 1140am CST Monday Jan 13 2025 /issued 308am CST Monday Jan 13 2025/ ..New NEAR TERM, SHORT TERM, LONG TER Marine Near Term (Now through Tuesday) Issued at 308am CST Monday Jan 13 2025 A rather large positively tilted upper trough over much of the CONUS becomes increasingly elongated through the period, with the flow over the forecast area becoming increasingly zonal. A surface low currently located off the mouth of the Mississippi River weakens and moves off to the east, and with it widespread rain over the area ends this morning. A cold front moves through the area as well today and ushers in cooler and drier air, with dry conditions expected for tonight through Tuesday night. Highs today and Tuesday will be in the lower to mid 50s. Lows tonight range from the mid 20s well inland to the mid 30s near the coast, and apparent temperature values get close to Cold Weather Advisory criteria (20 or less over interior areas and 25 or less for the southern portion of the area). Per coordination with adjacent offices, have opted for now to hold off on the issuance of a Cold Weather Advisory considering that criteria is just marginally met in some spots. That said, frost is anticipated to develop over most of the area overnight and persist into early Tuesday morning before dissipating. Lows Tuesday night range from the upper 20s well inland to the upper 30s/around 40 at the coast, and apparent temperature values will remain above Cold Weather Advisory criteria. A high risk of rip currents remains in effect through tonight, then a moderate risk follows for Tuesday with a low risk for Tuesday night. /29 SHORT THROUGH LONG TERMS... (Wednesday through Sunday) Issued at 308am CST Monday Jan 13 2025 An upper level shortwave trough digs south over the Plains mid week before moving east over the Southeast the end of the week. Timing and strength of this shortwave is causing issues in the deterministic models, with ensembles in better agreement. Have leaned that direction with the forecast. Rain returns to the forecast area by the end of the day Friday, before moving out Sunday night. A few rumblers may mix in over the Gulf and west of the forecast area, but over land areas, just rain is expected. Cooler air moves over the forecast area beginning Sunday night as post system northerly flow moves in. Temperatures remain at or below seasonal norms for Wednesday through Thursday. High temperatures in the mid 50s to around 60 expected. Low temperatures Wednesday night ranging from around 30 north of Highway 84 to upper 30s to around 40 south of I-10 see an increase Thursday night as southerly flow begins to increase moisture levels. Low temperatures ranging from the low to mid 30s along and north over most of the forecast area, with around 40 temperatures moving inland along the coast. Friday through Saturday will see above seasonal temperatures in the mid to upper 60s over the majority of the forecast area, with low temperatures ranging from the upper 40s north to near 60 near the coast. Cooler air moves in over the forecast area as the upper system moves off, with below seasonal temperatures returning to the forecast area. With onshore flow returning Friday and increasing into the weekend, a Low risk of rip currents mid week becomes High late Friday into the weekend. /16 Marine Issued at 308am CST Monday Jan 13 2025 Strong northeasterly winds gradually diminish to a light to moderate flow by Wednesday. A light to moderate easterly flow develops Thursday night then turns southerly and increases Friday into Friday night. A Small Craft Advisory (SCA) remains in effect for the Mississippi Sound, Mobile Bay and Pensacola Bay until noon today. The SCA (Small Craft Advisory) remains in effect for the near shore waters until 9 am Tuesday and for the 20-60 nm portion until noon Tuesday. Another SCA (Small Craft Advisory) may become necessary by Friday night. /29 NOAA Mobile AL Office: Watches - Warnings - Advisories AL...High Rip Current Risk through late tonight for ALZ265-266.
