Area Forecast Discussion National Weather Service Lake Charles LA 618 AM CDT Wed Aug 24 2022 ...New AVIATION... .SHORT TERM... (Today and tonight) Issued at 215 AM CDT Wed Aug 24 2022 Scattered thunderstorms are redeveloping already this morning. Radar estimates over the past 4 days from at some locations are 5 to 10", however most locations are 1 to 5" with lesser amounts near the coast. The ground is generally saturated across a large portion of the area, especially the northern zones. A cold front remains stalled to the north with a very moist air mass in place south of the boundary. PWATs are above the 90th percentile. With the weak convergence and upper divergence in place and the high moisture content, high rain chances are anticipated. While guidance has seemed to somewhat overestimate coverage, widespread convection is expected. Hi-res guidance is indicating fairly high rainfall totals over locations that have received significant amounts over the past few days, plus they are slightly move focused from Jefferson Co through Rapides. Opted to expand the FFA farther south for today. A lull in convection may occur this evening, however another round of wet weather is expected Thursday as the same pattern remains in place. For Friday the weak surface convergence begins to lift northwest, but the overall pattern will remain in place. More rain. && .LONG TERM... (Thursday through Tuesday) Issued at 215 AM CDT Wed Aug 24 2022 Forecast for this weekend into early next week look to remain on the wet side with above seasonal pops each day. The reason will be a relative weakness overhead in the sub-tropical ridge, while southerly flow continues to bring in abundant Gulf moisture. Even though there will be no low level surface boundary around to focus storm development, daytime heating and an active sea breeze should be enough for a good deal of showers and storms from late morning into the afternoon. With the expected extra cloud cover and convection, high temperatures each day are expected to be a little below climo norms. 07/Rua && .AVIATION... (12Z TAFS) Issued at 616 AM CDT Wed Aug 24 2022 Showers and storms will continue to produce lower vis and ceilings through the afternoon. A lull may occur late today, however additional convection may redevelop late tonight along the coast and move inland. SW winds will gradually back to SE during the period. && .PRELIMINARY POINT TEMPS/POPS...
