| Area Forecast Discussion National Weather Service Lake Charles LA 1242am CDT Wednesday September 9 2026 (Today through Tuesday) Issued at 1240am CDT Wednesday September 9 2026 Water vapor satellite imagery and upper air analysis depict a sprawling 500 mb ridge centered over the Ozarks in Missouri this evening, as well as a weak inverted trough located over the northern Gulf. At the surface, the CWA (County Warning Area) is located on the western fringes of an axis of high pressure centered off the NC Atlantic coast, which is yielding light southeasterly flow this evening. Deep moisture remains in place over the area, with RAP mesoanalysis indicating PWAT (Precipitable Water) values in the 2.0-2.2 inch range this evening. All convection has dissipated for the night with just a few areas of lingering high clouds left. The clear skies should allow temps to cool to near saturation, with overnight lows in the mid 70s inland and upper 70s near the coast. Would not rule out a few areas of patchy light fog or mist, particularly any inland areas that received rain today, but this looks quite isolated. Dense fog is not expected. Any fog that does develop will dissipate rapidly with sunrise. The upper level ridge will continue building into the Deep South for Wednesday, which will allow some drier (relatively speaking) air to advect into the column particularly in northern portions of our CWA. LREF mean PWAT (Precipitable Water) decreases to 1.7 inches Wednesday across our northern counties/parishes, but holds at or above 2 inches along the coast. The result will be a day of generally reduced convective coverage area-wide compared to previous days, particularly across central Louisiana where subsidence from the building ridge will be strongest. Scattered afternoon pulse convection looks to develop along and south of the I-10 corridor, furthest removed from the ridge and drier air and closer to the Gulf tropical wave. While instability will be more than sufficient for thunderstorms, recent guidance indicates it may be a bit more limited than previous days, with HREF mean SBCAPE only around 2000 J/kg along the coast. As a result, updrafts may be slightly less vigorous than earlier this week. However, any stronger cells that do form will need to be monitored for gusty downdraft winds given modeled DCAPE in the 800- 1000 J/kg range. Expect convection to dissipate around sunset. High temperatures look to be in the low 90s along the coast and mid 90s inland. By Thursday, the upper ridge will begin to break down over the Mississippi Valley, shifting eastward over the Southeast US. As it does so, the disturbance over the Gulf will slowly translate westward towards the Texas coast. This will result in a deep layer south to southeasterly flow over our CWA that will allow for PWATs (Precipitable Waters) to climb back above 2 inches area-wide (climatological 80th to 90th percentile for mid-September). These factors combined will all allow for an increase in convective coverage starting Thursday and continuing into the weekend, with numerous showers and thunderstorms expected each day. Rainfall will generally be beneficial, but given the anomalous moisture, there may be a threat for some isolated flash flood concerns in particularly susceptible locations. WPC has a Marginal Risk (level 1/4) of excessive rainfall for our entire CWA for both Friday and Saturday as a result. Temperatures look to drop a few degrees with the height falls and increase in clouds and precipitation during this period, with afternoon highs in the upper 80s to near 90 along the coast and low 90s inland. Ridging over the Southeast looks to start building back westward towards our area beginning Sunday. This is expected to result in a decrease in afternoon convection into the first half of next week, though sufficient moisture will remain in place for scattered thunderstorms. With the return of ridging and decrease in convection, expect afternoon high temperatures to tick back up a couple of degrees. Though we may be in meteorological fall, it will still feel like summer, with no significant cooling on the horizon through at least the next week. 64/Silas Marine Issued at 1240am CDT Wednesday September 9 2026 An axis of high pressure over the northern Gulf will result in a general pattern of light southeasterly winds and low seas over the coastal waters through the weekend. A weak tropical wave slowly moving across the northern Gulf Coast will bring daily chances of showers and thunderstorms throughout the period. Fire Weather Issued at 1240am CDT Wednesday September 9 2026 A moist airmass will bring scattered showers and thunderstorms to the southern half of the CWA Wednesday, expanding across the entire area for Thursday into the weekend. MinRH each day will generally be 45-60 percent inland and 60-75 percent along the coast. Fire weather concerns look minimal through this period, with rainfall expected to help improve drought conditions across much of the area.
