425 FXUS64 KLCH 232322 AFDLCH Area Forecast Discussion National Weather Service Lake Charles LA 622 PM CDT Sat Aug 23 2025 ...New AVIATION... .KEY MESSAGES... - A weak frontal boundary will linger offshore into next week. Rain chances will remain elevated near along the coast. - A building high pressure system over the Mountain West is expected to bring a dry northwest flow into the forecast area over the weekend with lower rain chances and less humid conditions Sunday into next week. - Another weak cold front may enter the area by the middle of next week. && .SHORT TERM... (Tonight through Monday night) Issued at 1209 PM CDT Sat Aug 23 2025 A stationary front is located along the coast with extensive showers and thunderstorms forming along the boundary. Satellite- derived PWAT shows the line of dry air has reached central Louisiana, with ground observations also showing a slight drop in dew points at the surface. This trend will thankfully continue as an upper-level ridge in the desert southwest will create a northerly flow, pushing the dry continental airmass to the Gulf Coast. This dry air intrusion will be strong, with PWATs expected to be near or below the 10th percentile through the middle of the week. Weather-wise, we are looking at some wonderful weather, especially for late August, with mostly clear skies, temperatures in the low 90s, and dew points in the low 70s. && .LONG TERM... (Tuesday through next Friday) Issued at 1209 PM CDT Sat Aug 23 2025 A second cold front will move across the CWA on Monday and Tuesday, bringing another shot of cooler and dry air. With this front, rain chances will be on the lower side, around 30%. Rain chances behind the front will drop as the dry air settles in place. Southern flow will start to pick up late in the week as high pressure starts to build along the eastern seaboards. The pleasant weather will continue next week, with highs staying in the low 90s all week. Inland areas could even see lows in the mid-60s later in the week. && .AVIATION... (00Z TAFS) Issued at 620 PM CDT Sat Aug 23 2025 Light winds and mostly clear skies can be expected area-wide overnight. Only exception will be areas of patchy fog that may develop near AEX around sunrise. Tomorrow, winds increase slightly through the morning hours, remaining light to moderate and generally out of the north through the day. Skies will fill in slightly through the afternoon but maintain VFR. && .MARINE... Issued at 1209 PM CDT Sat Aug 23 2025 Offshore convection will be the main concern for the next several days as a front stalls across the northern Gulf. Light offshore flow will continue through midweek. Waves will remain low between 1 and 3 feet. && .FIRE WEATHER... Issued at 1209 PM CDT Sat Aug 23 2025 Dry air will bring cooler temperatures and low minimum RH values. Afternoon RH values will drop into the mid to upper 30s. Low winds and green vegetation will keep fire danger low for the next week. && .PRELIMINARY POINT TEMPS/POPS...
