399 FXUS64 KLCH 300932 AFDLCH Area Forecast Discussion National Weather Service Lake Charles LA 432 AM CDT Tue Apr 30 2024 ...New SHORT TERM, LONG TERM, MARINE... .SHORT TERM... (Today through Thursday night) Issued at 319 AM CDT Tue Apr 30 2024 Main concern this morning is widespread dense fog forming across the region. Satellite imagery continues to show the expansion of fog and this will continue until sunrise. Expect improvement after sunrise with the dense fog adv expiring at 10 am. The rest of the day will see highs in the middle 80s with the majority of the area dry. There could be some isolated showers/storms in SETX, but confidence is low at this time. Wed/Thu confidence increases for showers/storms as multiple disturbances move across the region. Plenty of moisture and instability will be availble for storms. While severe weather is not expected at this time, some of the stronger storms could bring heavy rain. Therefore the WPC, placed portions of the area in a marginal/slight risk for heavy rainfall. && .LONG TERM... (Friday through Tuesday) Issued at 319 AM CDT Tue Apr 30 2024 Frontal bndry stalls across the region late week into the weekend, before finally washing out. This will result in daily showers/storms each afternoon into the weekend. It is possible, by early next week, mid-level ridging and a more progressive pattern may finally result in a reduction of POPs/drier weather. Daytime highs cool a little on Friday with highs in the lower 80s, but warm right back up by the weekend intop the middle/upper 80s. By early next week, ridging could push some interior locations in TX/LA into the lower 90s. && .AVIATION... (06Z TAFS) Issued at 319 AM CDT Tue Apr 30 2024 Little change from previous TAF thinking with clear skies and light winds now noted areawide. Patchy fog is already seen in area obs although terminal sites remain VFR attm. Still expect areas of BR/FG and possibly some low clouds to develop overnight. Vsby reductions to MVFR are anticipated over the next 2-3 hours, with occasional LIFR vsbys/cigs possible late tonight, mainly at the LA terminals. Conditions should improve to VFR by 15Z at the LA airports with cigs lifting/scattering by 17Z at BPT. VFR/light southerly winds expected to prevail thereafter. && .MARINE... Issued at 319 AM CDT Tue Apr 30 2024 Chances of showers and thunderstorms will increase through the middle of the week as the surface trough and deep layer upper level trough approaches the area. Onshore flow expected for the the period with an SCA possibly needed by Thursday as the pressure gradient tightens slightly more with winds in the gulf waters increasing above 20kts briefly. && .PRELIMINARY POINT TEMPS/POPS...
