008 FXUS64 KMOB 130031 AFDMOB Area Forecast Discussion National Weather Service Mobile AL 731 PM CDT Fri Jul 12 2024 ...New AVIATION... .AVIATION... (06Z TAFS) Issued at 724 PM CDT Fri Jul 12 2024 Scattered showers and thunderstorms continue to develop along a southward moving outflow boundary that is approaching I-10 in coastal Alabama. This will result in a period of reduced visibilities in heavier rain along with MVFR ceilings at KMOB and KBFM through at least 01z. There will also be a brief period of northerly winds between 5-10 kts with the associated outflow boundary as it progresses south. There remains uncertainty regarding if this boundary can initiate convection towards the beaches or if the outflow will undercut convection. Maintained a vicinity mention of thunder at KJKL through 02z. Further east, convection that developed near KPNS is showing signs of decay. All convection near the TAF sites should end between 02-03z this evening with skies clearing. Winds should remain light after convection dies out. Additional isolated to potentially scattered convection will again redevelop mainly along the bay and sea breezes on Saturday afternoon. Coverage will likely be lower tomorrow as upper ridging builds. Kept a vicinity mention to account for this potential. /JLH && .PREV DISCUSSION... /issued 322 PM CDT Fri Jul 12 2024/ ..New NEAR TERM, SHORT TERM, LONG TERM, MARINE... NEAR TERM... (Now through Saturday) Issued at 322 PM CDT Fri Jul 12 2024 A broad upper level ridge over the western Atlantic will continue to build westward through Saturday. At the sfc, a light west to southwest flow will maintain higher precipitable water values around 2 inches, mainly along the coast. Slightly drier air will exist inland with values around 1.8 inches. This will lead to similar conditions on Saturday with highs in the mid/upper 90s inland to low/mid 90s near the coast. Heat index values will climb into the 105 to 108 range during the afternoon across the southern third of the area. A heat advisory may be required across portions of the area. Otherwise, isolated to scattered showers and thunderstorms will develop near the coast during the morning and spread inland through the afternoon. Severe storms are not expected, however frequent lightning, gusty winds and brief heavy rain can be expected with the storms. /13 SHORT AND LONG TERM... (Saturday night through Friday) Issued at 322 PM CDT Fri Jul 12 2024 Summer marches on this week with continued heat but also some rain chances showing up towards the end of the week. High pressure will nose into the area Sunday through Tuesday leading to a rather standard summertime pattern. Rain chances will remain confined mostly to the seabreeze and land breeze circulations and then slowly spreading inland with outflow boundaries. Given the relatively benign flow and net subsidence over the area, coverage should remain rather scattered to isolated. Heat will be the main talk as moisture slowly builds and with the lack of cloud cover highs will be able to climb into the mid to upper 90s leading to heat indices around 105. The overall pattern will change by the middle of the week as a rather deep trough for this time of year digs into the eastern US. Deep southwesterly flow will develop a loft as moisture increases across the area. RAin chances will likely be on the rise as a subtle boundary slowly drifts southward into the central Alabama. If anything, this pattern appears to be a rather soggy period with the potential for several rounds of heavier rain as PWATS climb into the 2.25 to 2.5 inch range. The good news is that it would keep the temperatures down a bit with only highs in the low 90s. BB/03 MARINE... Issued at 322 PM CDT Fri Jul 12 2024 No impacts expected other than locally higher winds and seas possible near thunderstorms. /13 && .PRELIMINARY POINT TEMPS/POPS...
