319 FXUS64 KLCH 120809 AFDLCH Area Forecast Discussion National Weather Service Lake Charles LA 309 AM CDT Mon Aug 12 2024 ...New SHORT TERM, LONG TERM, MARINE... .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.
