974 FXUS64 KLCH 121132 AFDLCH Area Forecast Discussion National Weather Service Lake Charles LA 632 AM CDT Mon Aug 12 2024 ...New AVIATION... .SHORT TERM... (Today through Wednesday night) Issued at 309 AM CDT Mon Aug 12 2024 A stalled and diffuse frontal boundary remains along the coast early this morning. North of the front dewpoints are still in the mid 70s to upper 60s while coastal areas are in the mid to upper 70s. Aloft a ridge remains centered over Texas. Today the weak front will gradually lift back north while washing out. Moisture will once again surge north with dewpoints gradually increasing, but most notably over the interior locations with not much change expected along the coast. High temps will climb into the 90s. This combined with dewpoints in the 70s will produce apparent temperatures in the 100s. Locations in SE TX may even bump up to near heat adv criteria for an hour or two this afternoon. Also with the return of moisture a few showers or storms may be possible along the sea breeze. The upper ridge is expected to remain in place Tuesday and Wednesday suppressing convection, however a isolated to widely scattered shower may occur along the sea breeze. The main concern through mid week will be the heat. With the return of higher dewpoints and remaining upper ridge, apparent temps are forecast to climb into the 105 to 110 range each afternoon. && .LONG TERM... (Thursday through Monday) Issued at 309 AM CDT Mon Aug 12 2024 During the long term the region will remain stuck in a stagnant pattern with an upper ridge in place and gulf moisture streaming across the region. Isolated sea breeze showers may be possible, but very little cooling is anticipated from this afternoon convection. Hot and humid conditions are expected. && .AVIATION... (12Z TAFS) Issued at 630 AM CDT Mon Aug 12 2024 Mostly VFR conditions are anticipated through the period, however isolated to scattered showers and storms will be possible this afternoon along the sea breeze. This may cause a brief reduction in VIS if a shower impacts a terminal. Otherwise light onshore winds are expected. && .MARINE... Issued at 309 AM CDT Mon Aug 12 2024 A weak offshore flow is occurring this morning, however the front will lift back north this morning. A light onshore flow is then anticipated for the rest of the period. Isolated shower will be possible during the early morning hours most days. && .PRELIMINARY POINT TEMPS/POPS...
