428 FXUS64 KLCH 172330 AFDLCH Area Forecast Discussion National Weather Service Lake Charles LA 630 PM CDT Fri May 17 2024 ...New AVIATION... .SHORT TERM... (Tonight through Sunday night) Issued at 351 PM CDT Fri May 17 2024 The latest radar and satellite imagery reveal partly to mostly cloudy skies and light showers streaming in from the southeast this afternoon. This activity will likely continue into the evening hours, but should remain below severe limits. An approaching shortwave, in combination with high moisture content and instability, will bring another round of showers and thunderstorms late tonight into early Saturday morning for areas along and south of I-10 and the Gulf waters. The latest suite of high res guidance indicates that the onset of any convective development is likely to be after 2-3AM for areas along and south of a Lake Charles to Lafayette line, and is expected to move east to southeast into early Saturday morning. Forecast model soundings support the potential for damaging wind gusts and large hail with any severe thunderstorms. In addition to the potential for severe weather, locally heavy rain may also bring a threat for flash flooding for areas along and south of a Lake Charles to Lafayette line. HREF guidance indicates additional amounts of 1-2 inches will be possible through early Saturday. With the highest rainfall amounts expected to fall further south of the Flood Watch configuration, the Flood Watch has been cancelled for this evening. While there still may be minor issues with recent rainfall, expect fairly light rainfall amounts through this evening. Otherwise, the combination of light winds and high moisture content may result in the development of patchy fog tonight. Expect cloudy skies with low temperatures in the 60s region wide tonight. Ridging is expected to build over the region heading into the weekend, which will bring an end to the unsettled weather pattern. Highs will be in the upper 80s and low 90s with low temperatures in the upper 60s and low 70s. && .LONG TERM... (Monday through next Thursday) Issued at 351 PM CDT Fri May 17 2024 The work week will feature above normal temperatures with highs in the upper 80s and low 90s as high pressure and ridging prevail. In combination with the humidity, afternoon heat index values will rise into the mid to upper 90s each afternoon. Unsettled weather may return toward the end of the week as an upper level disturbance approaches, but most precipitation chances are expected to remain further north. && .AVIATION... (00Z TAFS) Issued at 624 PM CDT Fri May 17 2024 Rather stable conditions at the moment across the forecast area with mainly VFR ceilings and just some occasional light rain. The question for tonight is the development of any convective activity and if it will organize into a MCS. For now, it looks like any organized activity will develop late tonight and southeast of Lafayette to Cameron line. Therefore, only KLFT and KARA will have the mention of storms between 1808z/1812z. Otherwise, remainder of the terminals will see a redevelopment of low clouds and patchy fog with MVFR to IFR conditions. On Saturday, more stable conditions will filter with drier air that will allow for VFR conditions after 18/15z. Rua && .MARINE... Issued at 351 PM CDT Fri May 17 2024 Another round of showers and thunderstorms is expected to develop across the coastal waters late tonight into early Saturday morning. Winds and seas could be significantly stronger in the vicinity of any thunderstorms. Light to moderate winds will result in gradually falling seas late this weekend into next week. && .PRELIMINARY POINT TEMPS/POPS...
