714 FXUS64 KSHV 212004 AFDSHV Area Forecast Discussion National Weather Service Shreveport LA 304 PM CDT Sat Sep 21 2024 ...New SHORT TERM, LONG TERM... .SHORT TERM... (This evening through Sunday Night) Issued at 245 PM CDT Sat Sep 21 2024 The last official day of the summer season still certainly feels like it if you`ve stepped outside this afternoon as temperatures range from the lower to mid 90s across the region. Fortunately, dew points have mixed out fairly well today and humidity levels are tolerable with peak heat index values generally averaging in the upper 90s to lower 100s. Another relatively warm overnight period lies ahead with low temperatures ranging from the lower to mid 70s under mostly clear skies as the afternoon cumulus field will quickly fade after sunset. One more day of above average temperatures is expected on Sunday with the upper-level ridge will remain anchored along the Gulf coast, albeit flattening out somewhat as an upper trough begins to eject E/SE from the Rockies into the Central and Southern Plains. This trough will help to usher a cold front into the Middle Red Red Valley of southern Oklahoma and north central Texas by late Sunday afternoon. As this front slowly eases farther SE by Sunday evening into the overnight hours, some isolated convection will be possible north of the I-30 corridor. Otherwise, the remainder of the region will remain dry through the short-term period with just some patchy fog possible during the pre-dawn hours late tonight and again on Sunday night. /19/ && .LONG TERM... (Monday through next Friday) Issued at 245 PM CDT Sat Sep 21 2024 Starting the new work week will bring some changes to the forecast in the form of slightly milder temperatures and increasingly better rain chances as the week progresses. This will occur first with the aforementioned cold front, although the front will be relatively weak and likely stall out across the region through the mid-week timeframe. In fact, high temperatures will still be in the upper 80s to lower 90s across much of the region through at least Tuesday. By Wednesday, a deeper trough and much stronger cold front will quickly spill SE from the Great Plains with slightly higher rain chances and noticeably milder temperatures expected through the remainder of the week. Highs will generally range from the upper 70s to mid 80s behind the front with the associated upper-level low possibly becoming closed off invof our region and prolonging rain chances through the end of the week. /19/ && .AVIATION... (18Z TAFS) Issued at 1243 PM CDT Sat Sep 21 2024 For the ArkLaTex terminals, Chamber of Commerce summer day going with light southerly winds and hot temps. Upper high pressure overhead will keep convection away with only a cu field expanding this aftn. We have been drying out, so daybreak MVFR lingers at only marginal levels of light BR at our prone sites. Again tmrw will greet the new season with no appreciable difference. A weak cool front will edge in by midweek with clouds & convection. /24/ && .PRELIMINARY POINT TEMPS/POPS...
