560 FXUS64 KLCH 170851 AFDLCH Area Forecast Discussion National Weather Service Lake Charles LA 351 AM CDT Tue Sep 17 2024 ...New SHORT TERM, LONG TERM, MARINE... .SHORT TERM... (Today through Thursday night) Issued at 335 AM CDT Tue Sep 17 2024 The weak, quasistationary boundary that has been sitting over the area for the last three days is presently analyzed near the coast this morning with dewpoints ranging from 68 to 73 away from the coastline. Aloft, a broad upper level low resulting from the merging of the remnants of Francine and a now inland tropical disturbance will maintain weakness aloft across Acadiana through the day. The combination of these two features will result in scattered convection this afternoon primarily around the Atchafalaya basin, but isolated convection could develop as far West as Lake Charles. As has been the case the last couple of days, any convection that develops should wane around sunset. Upper level ridging over central Texas builds further into the region by Wednesday which should keep any afternoon convection isolated. Further entrenchment of the ridge on Thursday looks to suppress all convection. Daily temperatures will be running near seasonal normals both today and Wednesday with highs ticking up a degree or two Thursday in response to less cloud and precip coverage. Jones && .LONG TERM... (Friday through Tuesday) Issued at 335 AM CDT Tue Sep 17 2024 The extended period will be dominated by upper level ridging becoming centered nearly overhead Friday through early next week. This will prevent any appreciable precipitation while keeping temperatures at or slightly above seasonal normals. A weak gradient at the surface will maintain somewhat variable winds at 5 MPH or less. Jones && .AVIATION... (06Z TAFS) Issued at 1153 PM CDT Mon Sep 16 2024 Calm and VFR conditions ongoing with light winds and isolated patchy fog across the area. Fog will be possible across most of the terminals tonight, however widespread dense fog is not expected. Whatever does form will be quick to burn off shortly after sunrise. Going into the late morning and afternoon hours, some isolated showers and storms are possible however confidence in timing and location is low. Stigger/87 && .MARINE... Issued at 335 AM CDT Tue Sep 17 2024 A weak pressure gradient across the gulf this week will keep winds light and seas low. Isolated showers and thunderstorms will be possible across the near shore waters this afternoon with no appreciable precipitation chances expected the rest of the week. && .PRELIMINARY POINT TEMPS/POPS...
