| Area Forecast Discussion National Weather Service Lake Charles LA 1208pm CDT Wednesday September 27 2023 Long Term (Saturday through Wednesday) Issued at 350am CDT Wednesday September 27 2023 As we start the period on Saturday, a weak upper level disturbance/trough will have moved off to the east and over the northeast Gulf of Mexico. In wake of the disturbance, an upper level ridge will be building in across the region and strengthening. This will provide a dry west to northwest flow across the forecast area. This upper level ridge will hold across the forecast area through early next week. Meanwhile. surface high pressure over the northeast will ridge down into the forecast area allowing for low level east- northeast flow that will keep any reasonable Gulf moisture south of the area. This all shows a dry air mass settling in over the forecast area from the weekend into early next week. PWAT (Precipitable Water) values will be in the 1.0 to 1.10 inch range which is close to the 25th percentile of Storm Prediction Center daily climo to go along with 100H-50H mean layer RH values below 40 percent. Therefore, not expecting any significant shower activity. The dry airmass will allow for quite warm temperatures during the daytime with values some 5 to 10 degrees above climo norms and in the low to mid 90s, with temperatures dropping down into the mid to upper 60s at night. The main issue for over the weekend into early next week will be fire behavior danger, especially for locations that haven't received any wetting rains lately. Minimum relative humidity values during the afternoon will be in the 30 to 40 percent range with sustained 20 foot winds near 10 mph with gusts to 15 mph. Marine Issued at 350am CDT Wednesday September 27 2023 The frontal boundary situated over nearshore waters from yesterday appears to linger over the northern Gulf of Mexico over the coming days before washing out Thursday or Friday. Diurnal minimum convection could be present along this boundary in the coming overnight periods. Later this week, easterly winds and seas increase as the pressure gradient tightens between high pressure inland and an inverted trough.wave moving east to west over the central Gulf. Small craft should exercise caution and Small Craft Advisories may be needed. 11 Fire Weather Issued at 350am CDT Wednesday September 27 2023 Surface high pressure developing over southwest Arkansas will assist in driving dry air into the region today. This dry air will limit rain chances today with only limited shower/storm activity possible over coastal areas. Dry air will further move in over the coming days with daytime RH minimums dropping starting today, bottoming out in the mid 30s midweek, then upper 20s to mid 30s area wide for the end of the week through the weekend. A tightening pressure gradient from energy pulse moving over the north central Gulf of Mexico may result in some higher winds later in the work week. 11 NOAA Lake Charles LA Office: Watches - Warnings - Advisories LA...None.
