Area Forecast Discussion National Weather Service Mobile AL 648 AM CDT Tue Jun 23 2020 .AVIATION... 12Z issuance...Mostly VFR conditions to start off this TAF cycle with the exception of very localized MVFR cigs in a few spots. Scattered to numerous SHRA/TSRA are expected to develop later this morning (mainly after 23.13-14Z), particularly from far southwest AL into the western FL panhandle and adjacent south central AL. Additional SHRA/TSRA may then develop this afternoon into this evening, mainly over interior southeast MS and southwest/south central AL. A few of the stronger storms that develop could contain locally strong wind gusts in excess of 40 knots, frequent lightning, and reduced cigs/visibility. /21 && .PREV DISCUSSION... /issued 525 AM CDT Tue Jun 23 2020/ NEAR TERM UPDATE /Now Through Wednesday/...A moist and unsettled weather pattern is expected to continue across the region today through Wednesday. An upper level trough continues to move eastward across Alabama and the western Florida panhandle early this morning. Regional radar imagery shows no precipitation across our forecast area as of 330 AM CDT, although there is a more concentrated area of showers and a few thunderstorms moving across northern portions of Alabama. High resolution model guidance is generally in agreement that scattered to numerous showers and storms may develop over the next few hours across coastal southwest AL and the western Florida panhandle and adjacent south central AL as a secondary shortwave impulse lifts northeastward across this portion of the region this morning. We will keep POPs highest (50-60% coverage) roughly south of a Mobile to Luverne line through the morning hours, while also maintaining 30-40% POPs over our interior southeast MS/southwest AL zones giving respect to the broad trough axis and moist environment over our region. Convective coverage should tend to increase later this afternoon and this evening, particularly over interior portions of the area as yet another in a series of shortwave troughs moves across the region and also as a weak boundary pushes southward into northern portions of our CWA. Model soundings continue to indicate a very moist profile over our region this afternoon, with precipitable water values around 2 inches. MLCAPE values are expected to range from 1500-2500 J/KG and perhaps locally as high as around 3000 J/KG over interior areas late this afternoon into early this evening. Numerous showers and storms should develop/spread into interior southeast MS/southwest and south central AL during the late afternoon and evening hours. A few of these embedded storms will be capable of producing strong to locally damaging wind gusts, frequent lightning, and locally heavy rainfall this afternoon and evening. Convection should tend to decrease in coverage late this evening into the overnight hours. Wednesday continues to look even more unsettled over our forecast area as deep moisture spreads across the area in advance of an upper level trough moving over the vicinity of southeast TX/southwest LA and also as our area remains situated on the base of the large scale trough encompassing much of the eastern CONUS. Precipitable water values may increase a bit more into the 2.0"-2.1" across much of our area Wednesday. A somewhat more organized area of convection may potentially lift across our forecast area during the day Wednesday in association with passage of a shortwave impulse. There is some indication in the high-res guidance that a few locations could receive locally heavy rainfall amounts on the order of 1-2" and perhaps locally over 3" Wednesday as this convection spreads over the area, which could result in localized flooding of low lying/urban areas. A few strong to severe storms with damaging gusts will also again be possible. We will keep POPs high around 80% over much of the area Wednesday. High temperatures today will range from 86 to 91 degrees. Lows tonight will range from 68 to 73 degrees inland areas, and from 74 to 79 degrees along the coast. High temperatures Wednesday will be cooler yet, and range from 81 to 87 degrees west of the Alabama River, and from 86 to 89 degrees to the east. 21/22 SHORT TERM /Wednesday Night Through Thursday Night/...The short term will begin as an upper level trough progresses over the Ohio and upper Mississippi valleys, with mainly zonal flow aloft for the northern Gulf coast. This trough is expected to continue to progress east over the northeast CONUS, with an upper level ridge building in behind it over the ARKLATEX region and into Alabama by Thursday evening. This ridge will then take hold over the southeast CONUS by late Thursday and into early Friday. At the surface, a low pressure system over southern Arkansas with a warm front extended over the Tennessee Valley and stationary front draped over northwest Louisiana down through southeast Texas will begin to weaken by late Wednesday afternoon. By this time, the warm front is likely to stall, becoming a stationary front over the Tennessee Valley. This stationary boundary spanning from eastern Tennessee west through northern Louisiana and down into southeast Texas will further weaken and eventually dissipate through the day on Thursday. Surface high pressure will then begin to build into the region Thursday night. For sensible weather, scattered showers and storms are possible from Wednesday evening through Thursday afternoon. However, with the upper level ridge and surface high pressure building in over the region Thursday evening, dry weather will return to round out the short term. Lows Wednesday and Thursday nights will be in the upper 60s to lower 70s north of I-10 and in the mid to upper 70s south. Highs Thursday afternoon will generally be in the mid to upper 80s. Although, a few locations in the western Florida Panhandle as well as south-central Alabama could reach 90 degrees. Additionally, with dew points in the mid to upper 70s Thursday, heat indices are likely to reach the mid to upper 90s. Lastly, there is a MODERATE RISK of rip currents through Wednesday night, with a LOW RISK following for Thursday and Thursday night. /26 EXTENDED TERM /Friday Through Monday/...Weak ridging aloft continues to build into the Gulf and Southeast on Friday as a trough encompassing much of the East Coast slides further to the east. Ridging down in the low levels over the western Atlantic continues to build west into the Southeast and Gulf waters. Since the area remains on the western periphery of the surface ridge (at least over the weekend), southerly surface winds will continue to usher in moisture. While the building heights aloft support slightly less coverage of showers and storms and slightly warmer temperatures (at least in comparison to the past few days), the southerly flow will support the continuance of humid and muggy days. We transition into more of a typical summertime diurnal pattern with scattered afternoon convection firing up on the sea breeze and outflow boundary collisions in the extended time frame. That said, higher rain chances will largely be driven by where the ridge sets-up and subsequently where the weak shortwaves riding along the periphery of that ridge aloft also set-up. Temperatures in the extended will be around normal to slightly above normal. Saturday and Sunday look to be the hottest days in the extended with afternoon highs in the low 90s west of I-65 with more mid 90s in the forecast to the east of I-65 (especially across south central Alabama). The heat index will approach the 100-105° range in some locations over the weekend. 07/mb MARINE...Small craft operators should exercise caution over the coastal waters out 60 NM, including Lower Mobile Bay and the MS Sound east of Pascagoula today into this evening as southwesterly winds will be elevated between 13-18 knots with a few gusts over 20 knots. Seas will also be elevated between 2-4 feet today and tonight. Locally higher winds and waves will remain possible near scattered to numerous showers and thunderstorms. /21 && .MOB WATCHES/WARNINGS/ADVISORIES... AL...None. FL...None. MS...None.
