| Area Forecast Discussion National Weather Service Lake Charles LA 543am CST Thu Jan 8 2026 .SHORT TERM... (Today through Saturday night) Issued at 535am CST Thu Jan 8 2026 Upper level ridging along with high pressure in the northern Gulf have combined to cause a very warm January with high temperature records close to or being broken most days this week. This pattern is beginning to change as an upper level low is moving from Mexico into Arizona and will continue to track eastward. This trough will cause the first round of unsettled weather. As the low moves across the Great Plains we will see an increase in warm air advection as south winds will be gusting up to 25 - 30 mph. With the advection of warm moist Gulf air PWATs (Precipitable Waters) will quickly rise reaching 1.5 inches by Thursday afternoon, above the 90th percentile. Even with the high moisture content forecast, soundings show a thermodynamic profile that is unsupportive of widespread rain and the low-end rain chances (25%) support that analysis. Friday will be the day to watch as a second disturbance will move across a longwave trough and bring the threat of severe weather to the region. As stated in previous discussions this event will be a high shear/low CAPE event with 0-6 km bulk shear between 30 to 50 knots but MUCAPE around 1000 J/KG. Ahead of the front, convection will be isolated with long range CAM models indicating an environment supportive of isolated supercells, with the main limiting factor being a lack of CAPE. As the front approaches the area the most storm mode will likely be QCLS with embedded thunderstorms. Severe weather will be possible both ahead of and with the front. The Storm Prediction Center has the entire area under a Marginal Risk (level 1 of 5) with central Louisiana under a Slight Risk (level 2 of 5). The main threats will be damaging winds along with isolated tornadoes. Make sure to keep a close eye on the forecast for Friday. In addition to the severe weather, high PWAT (Precipitable Water) values, above the 95th percentile will lead to heavy downpours and the possibility of flash flooding. In addition to the severe weather threat the WPC has placed our area under a Marginal Risk (level 1 of 4) for flash flooding. Long Term (Sunday through Thursday) Issued at 535am CST Thu Jan 8 2026 After the passage of the cold front temperatures will plummet with overnight lows below freezing north of the I-10 corridor. For the rest of the weekend and into the start of next week temperatures will be close to average with highs in the upper 50s to mid 60s. Around midweek high pressure will be to our east and warm air advection will start to raise our temperatures and dew points. Marine Issued at 535am CST Thu Jan 8 2026 Dense sea fog continues to be an issue with visibilities below 1 SM until after sunrise with the advisory ending at 18Z. Strong south winds will cause conditions to be close to small craft advisory levels. A cold front will move offshore Friday night with the showers and thunderstorms lasting until Saturday morning. Behind the front strong north winds will impact the area through the start of the work week. Fire Weather Issued at 535am CST Thu Jan 8 2026 Light winds and high humidity has limited the risk of fire weather. A strong cold front will move across the region on Friday with strong north winds Saturday and Sunday. Minimum RH values will drop down to the 20 and 30% range.
