912 FXUS64 KMOB 260520 AFDMOB Area Forecast Discussion National Weather Service Mobile AL 1220 AM CDT Sat Apr 26 2025 ...New Aviation... .DISCUSSION... Issued at 221 PM CDT Fri Apr 25 2025 Now Through Saturday Night... A shortwave trof which extends from the north central Gulf coast to near the Ohio/Mississippi River confluence progresses off into the western Atlantic with broad upper ridging meanwhile building into the forecast region. A surface low well off to the north (associated with an upper trof) brings a weak surface trof/boundary through the forecast area late tonight which then drifts back to near the coast Saturday morning. The weak surface trof/boundary lingers near the coast through the afternoon hours before slipping into the marine area Saturday night. Current convection advancing into southeast Mississippi is anticipated to slowly progress to near the I-65 corridor and meanwhile diminish in coverage this evening. Dry conditions prevail for the overnight hours. Isolated showers and storms are possible west of I-65 on Saturday, and some spotty convection is also possible near the coast with the weak surface trof/boundary, but coverage at this point looks too limited to support mention of pops for that location. Dry conditions are expected for Saturday night. May see some gusty winds with convection that develops, but severe storm development is not anticipated. Lows tonight and Saturday night range from the lower 60s inland to the mid 60s near the coast. Highs on Saturday will be in the mid to upper 80s except for lower 80s at the immediate coast. A moderate risk of rip currents is expected through Saturday night. /29 Sunday Through Friday... An upper-level ridge, expanding from Mexico into the Central US at the start of the period, will build eastward into the southeast US. Prior to it moving into our area, one last shortwave trough will slide across the Deep South, bringing isolated to locally scattered showers and storms to the area on Sunday. As the ridge axis pushes overhead early next week, subsidence will help to keep our area dry for Monday, Tuesday, and Wednesday. Rain chances return to the forecast by Thursday and Friday as the ridge moves off to the east and an upper trough slides across the Tennessee/Ohio River Valleys. Temperatures will be very warm, with highs topping out in the upper 80s to low 90s, and lows in the mid to upper 60s. /96 && .AVIATION... (06Z TAFS) Issued at 1214 AM CDT Sat Apr 26 2025 General VFR conditions over the forecast area at midnight will see a drop, mainly in VISBYs, to low end MVFR/IFR as fog develops overnight. Best chance of lower VISBYs is expected to be southeast of I-65. After sunrise, any fog is expected to mix out by mid morning. An afternoon seabreeze is expected to develop, bringing general southerly winds to the southern half of the forecast area. /16 && .MARINE... Issued at 221 PM CDT Fri Apr 25 2025 A generally light diurnal flow will persist through Monday with an offshore flow developing at night and an onshore flow developing during the day. A light to occasionally moderate onshore flow will develop Tuesday and continue into Wednesday. No impacts are expected other than locally higher winds and seas possible near storms. /29 && .MOB WATCHES/WARNINGS/ADVISORIES... AL...None. FL...None. MS...None.
