192 FXUS64 KLCH 231117 AFDLCH Area Forecast Discussion National Weather Service Lake Charles LA 617 AM CDT Sat Aug 23 2025 ...New AVIATION... .KEY MESSAGES... - A weak frontal boundary will linger along the coast or just offshore into next week. Rain chances will remain elevated near the boundary today. - 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... (Today through Monday night) Issued at 1230 AM CDT Sat Aug 23 2025 A weak frontal boundary has stalled along the coast this past evening. Only a very modest reduction in dewpoints has been noted. Temperatures will remain near climo normals. Nocturnal convection is anticipated along the boundary this morning which may move just inland by or before sunrise. The stalled front stretches across the northern gulf coast and will remain in place through the weekend and into early next week. An upper ridge centered over the SW states will provide a northerly flow that will drive a drier airmass south across the central sections of the country. While showers and storms will be possible today, the best coverage will be near the coast or along the i-10 corridor. PWATs drop farther into Sunday and Monday which will decrease pops to isolated at best along the coast. Early next week the northerly flow will drive a reinforcing front south across the Mississippi Valley. && .LONG TERM... (Tuesday through Saturday) Issued at 1230 AM CDT Sat Aug 23 2025 Modest rain chances return by Tuesday as the next front moves into the area. There will be a very slight cool down behind this boundary, however dewpoints may fall into the 60s area wide which will be nice change of pace from the 70s to near 80 that the region has endured since June. By the end of the week the boundary washes out while lifting north. High pressure will build back in and the onshore flow will return. This will push the dewpoints back into the mid 70s by Friday. && .AVIATION... (12Z TAFS) Issued at 614 AM CDT Sat Aug 23 2025 Some patchy fog will be possible until shortly after sunrise, mainly at the KAEX terminal, then VFR conditions at all terminals through the remainder of the morning. Frontal boundary located near the coast could spark off some shower activity across lower southeast Texas and southern Louisiana during peak heating. So will mention VCSH or VCTS at KBPT/KLCH/KLFT/KARA after 23/19z. Away from the convection, VFR conditions with light winds will prevail. Rua && .MARINE... Issued at 1230 AM CDT Sat Aug 23 2025 Nocturnal thunderstorms will be possible each morning during the period. Light and VRB winds can be anticipated this weekend into early next week, but an onshore flow will return by late next week. && .FIRE WEATHER...
