167 FXUS64 KMOB 111132 AFDMOB Area Forecast Discussion National Weather Service Mobile AL 632 AM CDT Sat May 11 2024 ...New AVIATION... .AVIATION... (12Z TAFS) Issued at 632 AM CDT Sat May 11 2024 VFR conditions will continue has high clouds move overhead. Winds will remain light out of the north becoming light and variable overnight. BB/03 && .PREV DISCUSSION... /issued 433 AM CDT Sat May 11 2024/ ..New NEAR TERM, SHORT TERM, LONG TERM, MARINE... NEAR TERM... (Now through Sunday) Issued at 433 AM CDT Sat May 11 2024 Significantly calmer than 24 hours ago as upper troughing has dug into the eastern US and ridging begins to build over the central US. Unfortunately this will not last long as the next upper low is sitting there menacingly over the desert southwest. For now though we can enjoy some slightly cooler and drier conditions as the surface cold front has surged well offshore. Temperatures will be in the upper 70s to low 80s across most of the are this weekend and few locations might reach the mid 80s along the immediate coast. Lows tomorrow night will dip into the upper 50s to low 60s. A Moderate risk of rip currents will continue through today before decreasing to low Sunday. BB/03 SHORT TERM... (Sunday night through Monday night) Issued at 433 AM CDT Sat May 11 2024 Appears we will begin to see a quick transition to a weather pattern than becomes more unsettled to open up the work week. A low amplitude, short-wave upper ridge over the Gulf Sunday night translates eastward early in the upcoming week. This allows an active southwest flow at high levels to become oriented over the deep south. Meanwhile, an upper level storm system advances eastward out of the Central Plains, resulting in an increase in deep layer ascent within a zone of diffluent flow aloft from LA, northeast into AL through the day Monday and especially into Monday night. This coincides with a northward push of deep Gulf moisture with PWAT`s lifting above 2.00" as a surface warm front draped from LA to the northern Gulf Monday, lifts north northeast over the central Gulf coast Monday night. Notably, this lies well above 2 standard deviations above the climatological means for May 14th PWAT. Considering the orientation of and increase in high level flow, well above normal deep moisture and frontal ascent, the stage appears set for some decent rains to begin spreading in Monday and Monday night which could lead to localized flooding problems in areas subject to poor drainage, considering recent rains from last storm system. The latest Day 3 Excessive Rainfall Outlook (ERO) (12Z Mon-12Z Tue) shows the entire area within a slight risk. The National Centers do indicate that there is some potential for a targeted upgrade of the ERO to a moderate risk on later forecasts, but considering areal spread of the rainfall footprint amongst weather models, the result as of now lends to too low of confidence to go with it yet. There is also some potential of strong to isolated severe storms mainly along and south of the warm front`s warm sector late in the short term. At this time, the risk is marginal for our area Mon/Mon night, with the better risk west of the local area from the Lower MS River to east TX. Overnight lows moderate through the period, lifting to well into the 60s interior and into the lower to mid 70s coast by Monday night and well above the climatological means for mid May. With clouds and increase in precipitation Monday, highs range mostly in the upper half of the 70s interior to lower 80s coast. Rip current risk increases to Moderate. /10 LONG TERM... (Tuesday through Friday) Issued at 433 AM CDT Sat May 11 2024 An on-going area of better showers/storm coverage looks to be positioned along and east of I-65 Tuesday morning within a region of stronger flow and deep moisture ahead of an eastward advancing front. Precipitation is expected to decrease from west to east going into Tuesday afternoon and evening as the front settles southward and drier air begins to spread in at the base of the upper storm system`s trof axis pushing through the TN River Valley. The front stalls mid-week to the south of the coast and appears to head back north the latter half of the week in response to next southern stream upper level storm ejecting eastward out of TX. This favors yet another round of showers and storms. Could be some heavy rain and/or severe weather with the late week feature but too early for details. Daily highs in the 80s. Nights in the lower to mid 60s interior to lower to mid 70s coast. Rip current risk increases to High levels by the middle of the work week. /10 MARINE... Issued at 433 AM CDT Sat May 11 2024 A moderate to occasionally strong northerly wind this morning will slowly relax in the wake of a cold front. Winds will slowly become onshore by early next week in advance of our next system. Rain and storms return to the marine waters later next week as winds and seas steadily increase.
