| Area Forecast Discussion National Weather Service Lake Charles LA 1156am CDT Wednesday April 22 2026 (Today through Tuesday) Issued at 1209am CDT Wednesday April 22 2026 As of midnight, very isolated showers remain on radar, with this activity expected to wane shortly. Dry air remains in place per the latest sounding; however, with the influx of moisture rich southerly flow, it is not nearly as prominent as in previous soundings, nor will it remain. Temperatures are much warmer than 24 hours ago, ranging from the lower 60s to even some low 70s. Little relief is expected overnight, with lows only falling a few additional degrees lower due to cloud cover. With recent rainfall and light to calm winds, some areas of patchy fog may develop overnight into the mid morning hours. The best chances will be in SETX, where visibilities have already fallen below 5 SM. Over the day, a weak upper level disturbance will move east across the Southern Plains. At the surface, high pressure over the ArkLaTex will continue to shift eastward, allowing moisture rich southerly flow to return and persist through the remainder of the forecast period. As this disturbance approaches and the column continues to moisten, coverage and intensity of showers will increase. The last sounding had PWATs (Precipitable Waters) just below the 75th percentile, with forecast PWATs (Precipitable Waters) later today expected to exceed the 90th percentile. A Marginal Risk (level 1 of 4) for excessive rainfall is in place today. Deterministic rainfall totals have trended downward, now ranging from 0.25 to 1 inch, with probabilities of exceeding one inch in 24 hours remaining around 40 percent. Persistent southerly flow at the surface, combined with passing upper level disturbances, will support daily isolated to scattered showers. Instability is expected to remain weak through most of the work week; however, a few isolated, subsevere thunderstorms cannot be ruled out. Looking ahead to the weekend, conditions will bear watching as a deeper trough interacts with the plume of Gulf moisture that will stick around our region like the plague. A cold front will approach northern Louisiana before retreating, so cooler air is not expected to reach our area whatsoever. In fact, we can expect the opposite. By early next week, an upper ridge will take shape over the Mexican peninsula and Gulf, nudging north toward the western Gulf Coast states. Temperatures and dewpoints will remain above average, with afternoon highs in the mid to upper 80s (with some 90s not out of the realm of possibility) and overnight lows in the mid 60s to lower 70s. Dewpoints will generally range from the 60s to lower 70s. Marine Issued at 1209am CDT Wednesday April 22 2026 Surface high pressure continues to retreat eastward, with onshore flow returning. Scattered showers and a few thunderstorms will be possible today, with rain chances continuing through the period as additional upper level disturbances move through. Fire Weather Issued at 1209am CDT Wednesday April 22 2026 Continued southeast to southerly flow and multiple passing upper level disturbances will keep conditions humid across the region, with elevated rain chances through the week and into the weekend. This should keep fire weather concerns low and may allow for slight improvement to the ongoing drought. NOAA Lake Charles LA Office: Watches - Warnings - Advisories LA...None. TX...None. GM...None. |
