540 FXUS64 KLCH 040146 AFDLCH Area Forecast Discussion National Weather Service Lake Charles LA 746 PM CST Wed Dec 3 2025 ...New AVIATION... .KEY MESSAGES... - A coastal low developing and moving up the Texas gulf coast will produce showers and a few thunderstorms across the region this evening and tonight. - An approaching cold front will keep precipitation chances elevated Thursday and Friday. - Dry and cool conditions expected Sunday through early next week. && .SHORT TERM... (Today through Friday night) Issued at 740 PM CST Wed Dec 3 2025 Mostly calm conditions ongoing this late morning / afternoon with cloud cover spreading across the region. Temps are currently in the 40s to 50s, with MaxTs expected to top out in the lower 60s at best because of the expansive cloud cover. Easterly to SE flow has returned across the area, with increasing PWATs. Moisture will continue to increase as the coastal low progresses up the SETX coast and the trough nears. These two features will allow for scattered to numerous showers and isolated storms to become widespread across the region beginning late this evening to early tomorrow morning. The coastal low will be absorbed into the boundary which will meander along the coast through the short term. This will provide a focus for stratiform showers along with some embedded heavier rain and isolated storms. Heavy showers will be likely which could lead to ponding and minor street flooding, hence the Marginal Risk ERO today and tomorrow. && .LONG TERM... (Saturday through Wednesday) Issued at 740 PM CST Wed Dec 3 2025 Scattered showers will taper during the day on Saturday as a front is pushed through the region. A weak high pressure will sink into the Southern Plains on Saturday, with another high pressure spreading south on Monday. This will move off by Tuesday, with winds returning out of the south, however we are expected to remain rain free from early to mid next week. && .AVIATION...
