562 FXUS64 KMOB 060533 AFDMOB Area Forecast Discussion National Weather Service Mobile AL 1233 AM CDT Sun Sep 6 2026 ...New AVIATION... .KEY MESSAGES... Updated at 1229 AM CDT Sun Sep 6 2026 - Scattered to numerous showers and storms remain possible through the upcoming week. Any storms may produce gusty winds and torrential rainfall with isolated instances of flash flooding possible. - Peak heat index values of around 100-107 are expected through mid next week, warmest today and Monday. A Heat Advisory may be needed for portions of the area Monday with some spots approaching 108 to 110 heat indices. && .DISCUSSION... Issued at 1039 PM CDT Sat Sep 5 2026 We continue to sit on the periphery of upper ridging with subtle shortwaves aloft moving across the area. This will help to keep us hot and stormy as we head through Monday. Afternoon highs will be quite hot over the interior topping out in the middle to upper 90`s with heat indices warming into the 100 to 107 range. Nearer the coast, we don`t mix out quite as much and stay in the lower to middle 90`s for highs with similar heat indices. A shortwave moves across the area this afternoon, serving as a focus for thunderstorm development. Guidance varies significantly on the convective evolution, but the presence of the shortwave with ample instability gives confidence that at least scattered coverage of showers and storms will exist this afternoon areawide, lingering into the evening hours nearer the coast. There`s also a fair amount of uncertainty Monday depending on convective evolution upstream across Georgia/Carolina`s where a complex of storms may form and roll across the area. If that doesn`t exist, then we will likely see another day similar to Sunday with hot afternoon temperatures and scattered to numerous showers and storms. If storms are more robust in the morning, we`d likely stay cooler through the day with a drier afternoon. Any storms through Monday will have the potential to be strong, capable of producing strong wind gusts in addition to heavy rainfall. Isolated instances of flash flooding can`t be ruled out across urban areas where storms are able to train over the same locations. Upper ridging gradually spreads eastward across the region with deep layer easterly flow becoming established Tuesday into Wednesday. After this, ridging breaks down into late week as upper troughing becomes established across the eastern CONUS. This should keep us with a somewhat active pattern as subtle shortwaves continue to ride the periphery of the ridge. The expectation is for scattered to locally numerous showers and storms each afternoon, with daily highs in the lower to middle 90`s. Similarly, any storms may be able to produce gusty winds and heavy rainfall. Overnight temperatures stay steady state in the lower to middle 70`s. The rip current risk remains Low for Florida/Alabama beaches throughout the period, perhaps trying to reach Moderate Tuesday as stronger easterly flow becomes established. For now, we continue to advertise a Low risk but may need to bump that up in future forecast package updates. MM/25 && .AVIATION... (06Z TAFS) Issued at 1229 AM CDT Sun Sep 6 2026 Focus for this morning will be developing TSRA/SHRA across coastal locations, potentially impacting KJKA/KPNS, with Prob30`s introduce mainly from 10-14Z (but could begin earlier based on latest radar trends requiring AMD`s - will monitor). Otherwise, will see additional inland SCT TSRA/SHRA later this afternoon, but could see a few strong or locally severe storms drifting in from the north late afternoon into the evening. Main impacts will be gusty, erratic downdraft winds and reduced VIS/CIGs from heavy rain leading to periodic lower flight categories. Otherwise, VFR outside of SHRA/TSRA activity will prevail. KLG && .MARINE... Issued at 1039 PM CDT Sat Sep 5 2026 A generally light to occasionally moderate southwest to west flow prevails through Monday. Light to moderate easterly flow becomes established Tuesday into Wednesday. Light to occasionally moderate onshore flow returns for the remainder of the week into the weekend. Seas generally stay around 1 to 2 feet throughout the upcoming week. Scattered to numerous showers and thunderstorms remain possible during the morning hours each day with the potential to produce gusty winds and waterspouts. MM/25 && .PRELIMINARY POINT TEMPS/POPS...
