Area Forecast Discussion National Weather Service Lake Charles LA 623am CDT Thu July 17 2025 .SHORT TERM... (Today through Saturday night) Issued at 1227am CDT Thu July 17 2025 Scattered showers and thunderstorms are located to the east in southeast Louisiana and are associated with a weak tropical disturbance over the northern Gulf. This system remains unorganized, and additional strengthening is looking more unlikely, with the NHC now giving the system a 30% chance of development. Regardless of whether or not the system becomes named, the main concern for our region will remain heavy rainfall and flash flooding. An Excessive Rainfall Outlooks are in place Thursday through Saturday with a Moderate risk (level 3 of 4) in place for Friday, when the bulk of the rain is expected. A large amount of tropical moisture is in place with this system, and precipitable water (Pwats) will rise above 2 inches, which would put PWATs (Precipitable Waters) into the 90th percentile. In addition, the GFS (Global Forecast System) is highlighting the possibility of record-breaking PWAT (Precipitable Water) values over 2.4 inches across southwest and central Louisiana. Ensemble tables from the ECMWF support the GFS, showing PWAT (Precipitable Water) values above the 99th percentile on Friday and Saturday. Forecast sounding profiles are also concerning for a flash flood setup, with "skinny" CAPE profiles and high freezing levels that are favorable for efficient warm rain processes. The range for rainfall totals remains consistent from previous model runs, with widespread 2 to 6 inches and local maximums up to 15 inches. Because of these factors, the Flood Watch now extends across most of southwest Louisiana and now includes Lake Charles. Long Term (Sunday through Thursday) Issued at 1227am CDT Thu July 17 2025 After the passage of the disturbance, our weather pattern will return to summertime norms with weak ridging aloft. For the extended forecast, Probability of Precipitation will remain in the 20 to 30% range. Midway through next week, the NBM has temperatures rapidly rising into the mid to upper 90s, with heat index values well into the triple digits. If this pans out then heat advisories should be expected for next week. Marine Issued at 1227am CDT Thu July 17 2025 The tropical disturbance is not expected to produce much in the way of wind, and sustained winds are expected to stay below the 20-knot threshold for a Small Craft Advisory. Exercise caution headlines may be needed, but even that looks marginal right now. Scattered thunderstorms and reduced visibility due to heavy rainfall will be the main threats to mariners through the weekend. Near thunderstorms winds and waves will be locally higher. Background wave heigheights will be between 2 and 4 feet. Fire Weather Issued at 1227am CDT Thu July 17 2025 Soaking rain is expected area-wide Thursday through Saturday, with widespread 2 to 6 inches of rainfall. Minimum RH values will remain in the 40 to 60% range with light winds.
