020 FXUS64 KSHV 291859 AFDSHV Area Forecast Discussion National Weather Service Shreveport LA 159 PM CDT Mon Apr 29 2024 ...New SHORT TERM, LONG TERM... .SHORT TERM... (This evening through Tuesday Night) Issued at 104 PM CDT Mon Apr 29 2024 Weak upper-level ridging to prevail through the short-term period allowing for dry conditions areawide. Light and variable winds overnight to remain light and out of the southeast around 5 mph on Tuesday due to a relaxed pressure gradient across the region. High temperatures are forecast to climb into the 80s on Tuesday, falling into the low to mid 60s on Tuesday night. With light southerly flow, a weak surface boundary lingering a across the region, and a moist airmass in place from recent rainfall, fog may be an issue tonight. For this forecast package, went ahead and made mention of widespread fog areawide tonight. /05/ && .LONG TERM... (Wednesday through next Sunday) Issued at 104 PM CDT Mon Apr 29 2024 Southerly flow to increase on Wednesday as the pressure gradient tightens across the region. Additionally, with near zonal flow aloft, moisture to increase allowing for mostly cloudy skies areawide. Scattered showers and thunderstorms will be possible during the afternoon along a lingering frontal boundary that is forecast to lift north with high temperatures in the warm sector behind the front to climb into the mid 80s. A surface low across the Central Plains will lift northeast on Thursday leaving a frontal boundary in its wake that will push south across the ArkLaTex on Thursday night bringing another round of widespread convection across the region. Impulses moving downstream within a southwest upper-flow pattern interacting with a remnant frontal boundary across the ArkLaTex will maintain a chance for scattered convection through the remainder of the work week into the weekend. Storms producing locally heavy rainfall will be possible each day. /05/ && .AVIATION... (18Z TAFS) Issued at 1243 PM CDT Mon Apr 29 2024 For the ArkLaTex terminals, mid&upper level decks have cleared all but KMLU. The low decks are lifting/scattering for all our TX sites, and likewise into AR/LA this aftn with better warming. Weak surface high in the wake of nocturnal convection is basically from the rain cooled air. No wind flow around an air mass this go around. SFC wind will remain light & var for us with SW flow aloft off the deck and generally W/SW for climb out and FLs. Overnight, wet ground and near calm wind will bring LIFR/IFR mostly for FG/BR, which will improve quicker tmrw w/ better sun. /24/ && .PRELIMINARY POINT TEMPS/POPS...
