| Area Forecast Discussion National Weather Service Lake Charles LA 1211am CDT Thu September 17 2026 (Today through Wednesday) Issued at 1200am CDT Thu September 17 2026 Wx map currently features elongated high pressure extending SW of the appalachians into the Mississippi Valley while broad surface ridging remains over the western Gulf Coast. Abutting the ridge pattern is a shallow trough migrating east below the Louisiana coastline. Normally, coastal troughs pose higher chances for precipitation inland, however, dry air from the northeast will prevent much activity from organizing north of the immediate coast. Conditions inland will remain relatively dry and hot with temperatures hedging into the upper 90s across interior Southeast Texas and central Louisiana. The coastal trough will dissipate over the upper Texas coastline into early Friday with winds / seas gradually easing and abating through the morning. Dry weather continues Friday into the weekend with the mid and upper levels filtering in the less humid continental air. By Sunday, the forecast begins to shifts back to widely spread low end chances for precipitation into the following week. An upper level closed low will follow the late summer easterly trades across Florida peninsula. There is some disagreement whether or not the feature will remain closed or open to broader wave / disturbance which could pull in higher moisture toward the end of the forecast period. In the meanwhile, Monday, temperatures are forecast to hold in the mid 90s with the exception of the coastal parishes and counties. Barometric pressure will drop as the previous ridge pattern breaks down through Tuesday while troughing deepens at the surface, broadly across the Gulf. The present forecast trends keep modest northerly upper level flow with mostly easterly low level flow above the surface. For interior locations above the I-10 corridor, that is not very promising for better rainfall potential given poor effective inflow. However, we are speaking six to seven days out trending into the middle of next week which keeps similar temperatures and chances for precipitation in the forecast. Thus, I will caveat there is room for the upper air pattern to adjust better moisture into Southwest Louisiana and Southeast Texas with the analysis of subsequent data. Kowalski / 30 Marine Issued at 1200am CDT Thu September 17 2026 A fairly tight pressure gradient will keep easterly winds elevated through this evening. Winds will slowly decrease into Friday and through weekend as high pressure moves off the Atlantic coast. As per recent forecast, the Small Craft Advisory has been adjusted to continue offshore east of Cameron, LA until 1AM CDT Friday where offshore winds / seas will remain slower to ease and abate. Fire Weather Issued at 1200am CDT Thu September 17 2026 Dewpoints will lower today and Friday as a drier airmass filters in. Relative Humidity values may fall into the 30s across interior areas through Saturday. Chances for precipitation do increase early next week, but only to conditional and low end isolated chances as some low level moisture works its way back onshore. NOAA Lake Charles LA Office: Watches - Warnings - Advisories LA...None. TX...None. GM...Small Craft Advisory until 7pm CDT this evening for GMZ450-470. Small Craft Advisory until 1am CDT Friday for GMZ452-455-472- 475. |
