492 FXUS64 KLCH 041750 AFDLCH Area Forecast Discussion National Weather Service Lake Charles LA 1150 AM CST Tue Nov 4 2025 ...New SHORT TERM, LONG TERM, AVIATION, MARINE, FIRE WEATHER... .KEY MESSAGES... - Flow off the Gulf will help bring warmer temperatures and higher humidity through the end of the week. - With stable conditions and an increase in low level moisture fog may be an issue tonight and again Wednesday night into Thursday morning. - A sharp Canadian cold front will push through Sunday bringing unseasonably cold temperatures early next week. && .SHORT TERM... (Today through Thursday night) Issued at 1140 AM CST Tue Nov 4 2025 Surface ridge centered over the southern Appalachians will gradually move to the east and this will allow a light southeast flow from the Gulf to develop and persist during the period. This will help increase low level moisture and bring about a warming of temperatures to above seasonal norms. High pressure aloft will keep any rain chances from occurring despite the increase in moisture. However, fog may become more of an issue over the next couple of nights with stable conditions to go along with clear skies and light winds, radiational cooling should allow air temperatures to reach dew points. For tonight into Wednesday morning, probs only showing about a 20 percent chance of visibility less than 1/4 of a mile so will hold off on any dense fog advisory. Wednesday night into Thursday morning shows a better chance of dense fog. Rua && .LONG TERM... (Friday through Tuesday) Issued at 1145 AM CST Tue Nov 4 2025 Will start out with very warm and humid conditions with flow continuing off the Gulf. A weak upper level disturbance may bring about a small chance for showers and a few thunderstorms on Friday. However, at this point overall rainfall amounts look to be light. Over the weekend, ridging along the Pacific will allow for a dip in the Jet stream with a large trough east of the Rockies opening the door for some cold Canadian air to move down toward the region. This Canadian cold front is expected to arrive on early Sunday with guidance showing the coldest air of the season so far. NBM deterministic values which is near the ensemble mean suggest the potential for freezing temperatures for locations of upper southeast Texas and central Louisiana. Rua && .AVIATION... (18Z TAFS) Issued at 1135 AM CST Tue Nov 4 2025 High pressure at the surface and aloft will keep mainly stable conditions in place. Light southeast winds will help bring in some shallow low level moisture this afternoon. With clear skies and nearly calm winds tonight expect at least patchy fog to develop at all terminals with MVFR to IFR between 05/09z-13z. Rua && .MARINE... Issued at 1132 AM CST Tue Nov 4 2025 High pressure at the surface will move off to east of the Mid- Atlantic states allowing light to modest winds to become more easterly then southerly through the end of the week. && .FIRE WEATHER... Issued at 1130 AM CST Tue Nov 4 2025 High pressure aloft will keep rain chances out of the forecast for the next couple of days. A southerly flow will help increase low level moisture with afternoon minimum relative humidity values above 50 percent on Wednesday and Thursday. Patchy to widespread fog is also expected during the night and early morning hours. && .PRELIMINARY POINT TEMPS/POPS...
