| Area Forecast Discussion National Weather Service Lake Charles LA 1226pm CDT Tuesday September 23 2025 .SHORT TERM... (Tonight through Thursday night) Issued at 1221pm CDT Tuesday September 23 2025 An upper-level low is digging south from the northern Rockies. At the surface, low pressure and its associated cold front are currently located in the Great Plains. This front will move across the region Wednesday afternoon and into the evening hours. The Storm Prediction Center has placed us under a Marginal Risk (level 1 of 5) for severe weather. Looking a little deeper at the kinematics for the event, ML CAPE will be approximately 2000 J/kg ahead of and along the front, with MU CAPE over 2500 J/kg. Looking at the 0-6 km winds, CAMs are showing weak shear values from 20 to 25 knots, but that will be sufficient to support the development of a QLCS. The Storm Prediction Center has also highlighted the risk for damaging winds, and model soundings support that assessment with dCAPE values over 800, further indicating the chance for damaging downdrafts with the storms tomorrow. There is also a Marginal Risk (level 1 of 4) for flash flooding tomorrow, as PWAT (Precipitable Water) values will be above 2 inches, which is above the 90th percentile. With the tropical air mass currently in place, we will have a “skinny” CAPE profile, and with the freezing level above 15 kft, we should expect efficient rainmakers during this event. As the front moves towards the coast, it will start to slow with mid-level flow paralleling the front. Rainfall totals will be between 1 and 3 inches, with local pockets up to 6 inches being possible. Along and south of I-10 will see the most rain on Wednesday. By Thursday morning, the front will be near the shore and will slowly fade away as it moves offshore. Behind the front, cool, dry air will move into the area with rain chances dropping as we go into the afternoon. Long Term (Friday through next Monday) Issued at 1221pm CDT Tuesday September 23 2025 Our post-frontal weather will be pleasant and cool. Cold air advection behind the front will keep our highs in the 80s, while overnight lows will drop into the 60s for the rest of the week. Behind the front, a combination of high pressure and dry air will lead to clear skies and no rain for the rest of the week and into the weekend. The most noteworthy thing about the long-term forecast is the lack of features and noteworthy impacts. Marine Issued at 1221pm CDT Tuesday September 23 2025 High pressure continues to keep conditions calm offshore with winds below 10 knots and seas below 4 feet. Wednesday, an approaching front will lead to an increase in winds and waves with gusts near 20 knots and waves approaching 5 feet. As the front moves offshore, showers and thunderstorms will be widespread with high winds and waves near convection. Behind the front, conditions will be benign with low winds and waves. No marine hazards are expected today. Fire Weather Issued at 1221pm CDT Tuesday September 23 2025 Widespread rain tomorrow will provide some needed relief across the region, with widespread 1 to 3 inches of rainfall expected. After the front moves through the region, dry air will filter south, dropping our minimum RH values down to 40%. Behind the front, winds will remain light with 20-foot winds staying below 10 mph.
