832 FXUS64 KLCH 040508 AFDLCH Area Forecast Discussion National Weather Service Lake Charles LA 1208 AM CDT Mon Aug 4 2025 ...New SHORT TERM, LONG TERM, AVIATION, MARINE, FIRE WEATHER... .KEY MESSAGES... - Some drier air will continue over the area through Monday with lower rain chances, and with lower humidity will help keep the heat risk in check. - Expect a return to typical summertime pattern by the mid week. Moisture pooling in lower Acadiana may result in higher rain chances in this area compared to everyone else. && .SHORT TERM... (Today through Wednesday night) Issued at 1200 AM CDT Mon Aug 4 2025 Dry, northerly flow will result in another day of quiet weather with little to no PoPs. Increasing heights will result in slightly warmer temperatures today, but with the dry conditions, Heat Indices should only max out in the 95 to 103F range. Late Monday into Tuesday, trof amplifies down through the heart of Louisiana. This could result in a pooling of moisture within Lower Acadiana, and thus very slightly higher PoPs (30 to 45%) will be possible during daytime hours. Heat conditions should be very slightly elevated from Monday with highs in the low to mid 90s and HIs topping out in the upper 90s to 105F range. Wednesday`s pattern appears similar to Tuesday, expect similar conditions. 11/Calhoun && .LONG TERM... (Thursday through Monday) Issued at 1200 AM CDT Mon Aug 4 2025 Weakness lingering into the longterm period will allow a semi-return to normal summertime pattern. Hot and mostly dry inland with daily chances of PoPs at coastlines on the seabreeze. High pressure does appear to hang around from the southwest US, so higher heights in western zones will likely bring about hotter conditions through this area. However, with dry fetch off inland areas will keep the daily Heat Index in check. As heights increase from the west, expect a heating trend to return from west to east (highest highs in west areas, lower to the east thanks to area rainfall.) A return to highs in the mid to upper 90s is possible for those north and west, highs topping in the lower 90s towards the coastline. 11/Calhoun && .AVIATION... (06Z TAFS) Issued at 1200 AM CDT Mon Aug 4 2025 Northerly flow will persist as trof slides down on eastern fringe of high over east Texas. Dry airmass and subsidence will bring about hot, dry and VFR conditions to area forecasts. && .MARINE... Issued at 1200 AM CDT Mon Aug 4 2025 With boundary situated over coastal waters, expect elevated rainchances to persist in the evenings and overnight hours. A trof moves into the northeast Gulf which will keep elevated rain chances for coastal waters into majority of the next work week. Outside of nearby showers and thunderstorms, wind and seas are forecast to remain low and offshore through the forecast time frame. && .FIRE WEATHER... Issued at 1200 AM CDT Mon Aug 4 2025 Northerly flow will persist with a fetch of drier air filtering down from the northwest. There is a low chance of showers and isolated thunderstorms in very coastal areas. Otherwise, hot and dry conditions expected today. Tuesday, a trof moves into the region which may induce localized moisture and rain chances in Lower Acadiana Tuesday and Wednesday. North of this corridor should remain dry but with moisture still in place. Minimum RH values today into the start of the work week will vary in the 40 to 70 percent range. && .PRELIMINARY POINT TEMPS/POPS...
