028 FXUS64 KLCH 292348 AFDLCH Area Forecast Discussion National Weather Service Lake Charles LA 648 PM CDT Mon Apr 29 2024 ...New AVIATION... .SHORT TERM... (Tonight through Wednesday night) Issued at 317 PM CDT Mon Apr 29 2024 Convection is gradually exiting the area to the east with light to moderate rain lingering south and east of New Iberia and over the gulf waters. Some spotty flooding is also continuing across interior SE TX and West LA from previous rain. The upper disturbance responsible for this morning;s convection will continue east and away. This will give the region a period of quiet weather with light winds that is expected to last through tonight. Low lvl moisture from today`s rain may combine with the light winds and clear skies to allow fog to develop around sunrise Tomorrow the flow will again turn SE with surface moisture being pulled back north. While not mentioned in the forecast, an isolated shower may be possible by afternoon in SE TX and western LA as the moisture gets pulled back toward the plains. Showers and storms may be possible locally again by Wednesday. Another system will move into the plains and gradually move closer for the extended portion of the forecast. Ahead of this disturbance, ample moisture will be in place and with afternoon heating, scattered convection will be possible. && .LONG TERM... (Thursday through next Sunday) Issued at 317 PM CDT Mon Apr 29 2024 The beginning of the long term will be active as a weak frontal boundary is pushed into the plains before stalling out along the northern fringe of the CWA. Thanks to the rainfall received today (Monday), flooding will be possible with additional rainfall amounts expected on Thursday and Friday. As a result, WPC has place us in a Marginal Risk for excessive rainfall. As this will be May, the front is not going (nor expected) to bring down significantly cooler or drier air. Temperatures will be held to the low 80s thanks to cloud cover and rain Thursday and Friday while daytime temps will rise into the mid to upper 80s for the rest of the period. Overnight temps will be in the upper 60s and lower 70s with near matching dewpoints. Stigger/87 && .AVIATION... (00Z TAFS) Issued at 634 PM CDT Mon Apr 29 2024 VFR conditions with mostly light winds noted across the region (feels like its been a while since we could say that). SC/CU will continue to diminish this evening, while cirrus associated with the exiting storm system will shift east. The overnight combination of clear skies, light or near calm winds and extremely moist ground will set the stage for areas of fog and possibly some low clouds to develop. MVFR vsby reductions expected to develop by 06-08Z, with occasional LIFR vsbys/cigs possible late tonight, mainly at the LA terminals. Vsbys should improve to VFR by 15Z with cigs lifting/scattering by 17Z. VFR/light southerly winds to prevail thereafter. 24 && .MARINE... Issued at 317 PM CDT Mon Apr 29 2024 Winds continue to decrease with storms exiting the area. The light and VRB flow will turn back southeast then increase into the 10 to 20kt range by Wednesday. An SCA may be needed by Thursday as the pressure gradient tightens slightly more with winds in the gulf waters increasing above 20kts briefly. && .PRELIMINARY POINT TEMPS/POPS...
