| Area Forecast Discussion National Weather Service Lake Charles LA 631pm CDT Wednesday August 26 2026 (This evening through next Tuesday) Issued at 1246pm CDT Wednesday August 26 2026 A 500 mb high is centered near the border of Arizona and New Mexico. This system extends across the Gulf Coast and is the main synoptic feature for our forecast. Clear skies due to this ridge will cause temperatures to skyrocket today, with afternoon highs expected to be in the triple digits for central Louisiana and the interior portions of southeast Texas. Elsewhere, temperatures will be slightly better, but not by much, as highs will be in the upper 90s and could tip over the century mark for an hour or so. This heat, along with dew points in the 70s, will cause the heat index to be close to 110F. An area-wide heat advisory is in effect for today. On Thursday, we will have enough cloud coverage during the first half of the day to knock highs down a few degrees, so a heat advisory looks unlikely. For the rest of the week, temperatures will be a few degrees above normal, but there will be some relief from the heat. Make sure to take heat precautions by staying hydrated and taking breaks from the heat. With the ridge located to our west, we are under northerly flow aloft; as short-wave troughs rotate around the high, they bring instability to our region. An MCS (Mesoscale Convective System, a complex of thunderstorms which becomes organized on a scale larger than the individual thunderstorms) is expected to develop in Arkansas and travel south across the state. Models show a robust environment with MUCAPE values between 2500 and 3000 J/kg and MLCAPE around 1500 to 2000 J/kg. As is typical for our summertime events, bulk and low-level shear will be low, with 0-6 km shear below 20 knots. Similar to previous events, DCAPE values will be high, around 900 J/kg. Downdrafts from these storms should propagate far enough ahead of the updrafts to sustain the MCS as it moves south. Timing for the main severe threat will be overnight, from midnight until early morning. The Storm Prediction Center has placed our area under a Marginal Risk (level 1 of 5) for severe weather tonight, with the main threat being damaging winds. There is also a heavy rain threat with this system as PWAT (Precipitable Water) values will be over 2 inches, near the 90th percentile. For the rest of the extended forecast, the weakening ridge will lead to less heat and more afternoon showers. Marine Issued at 1246pm CDT Wednesday August 26 2026 During the early morning hours, a line of thunderstorms will move off the coast. Near these storms, conditions will quickly worsen with locally high winds and waves. Background winds will remain light and primarily from the south. Waves will also remain on the low side, below 3 feet for the rest of the week and into the weekend. Fire Weather Issued at 1246pm CDT Wednesday August 26 2026 Rain chances return to the forecast as high pressure aloft starts to weaken. We will also see temperatures return close to normal with highs in the low to mid 90s. MinRH values will be around 50% with light winds.
