291 FXUS64 KMOB 270932 AFDMOB Area Forecast Discussion National Weather Service Mobile AL 432 AM CDT Sun Apr 27 2025 ...New Discussion, Marine... .DISCUSSION... Issued at 351 AM CDT Sun Apr 27 2025 Through Monday night... Upper level shortwave energy that has topped an upper ridge stretching north over the Plains moves south along the east side of the ridge Sunday into Sunday night, allowing the ridge to become re- established Monday. Surface high pressure builds off the Carolina coast early in the coming week, with a ridge building southwest over the Southeast. A surface boundary that has stalled over the Southeast washes out and a more organized southeast to southerly flow becomes established over the Lower Mississippi River Valley and western half of the Southeast in response. Even with the onshore flow, high moisture levels over the Southeast (1.4"-1.6") see a drop Monday into Monday night (to around 1") as subsidence created drier air in the mid and upper levels over the Gulf moves inland over the Lower Mississippi River Valley. Already low rain chances Sunday (slight chance east of the Tombigbee River) decrease even further Monday as a result. Low level moisture remains high enough for patchy overnight fog to develop the next few days, though. Subsidence from the upper ridge will keep temperatures well above seasonal norms through the Near Term. High temperatures in the mid to upper 80s well inland from the coast, low to mid 80s closer to the coast are expected Sunday and Monday. Low temperatures in the low to mid 60s are expected north of I-10, mid to upper south to the coast are expected Sunday and Monday nights. A Moderate Risk of Rip Currents today quickly settles to Low as organized onshore flow eases. /16 Tuesday through Saturday... An upper ridge pivots eastward over the southeast states through Wednesday, leading to dry and continued well above normal temperatures. The influence of the ridge lessens its grip the second half of the work week as it shifts east off the southeast US coast. Meanwhile, an upper level storm system approaches the lower MS River Valley Thursday. With this feature`s eastward advance, an attendant cold front settles to the coast by later in the day Friday. An increase in cloud cover and rain chances expected Thursday and Friday. The front pushes south Saturday and brings a return to drier weather. /10 && .AVIATION... (06Z TAFS) Issued at 1215 AM CDT Sun Apr 27 2025 VFR conditions over the forecast area are expected to see local drops to low end MVFR/IFR after 09z as fog develops. Best chance will be southeast of I-65. Areas east of the Tombigbee will see a slight chance of afternoon showers and thunderstorms Sunday afternoon, with local drops in conditions to low end MVFR possible in the stronger storms. Any convection will quickly decrease with the setting sun Sunday evening. /16 && .MARINE... Issued at 351 AM CDT Sun Apr 27 2025 A light and variable, diurnally driven flow is expected into the coming week. As onshore flow becomes established Tuesday and remains so through the rest of the week, winds remain light to at times moderate, with a slow increase in waves as swell from the Gulf increases. && .PRELIMINARY POINT TEMPS/POPS...
