958 FXUS64 KLCH 182356 AFDLCH Area Forecast Discussion National Weather Service Lake Charles LA 556 PM CST Tue Nov 18 2025 ...New AVIATION... .KEY MESSAGES... - Areas of fog are expected tonight, however, lighter winds aloft will allow for the potential of the fog to become dense in greater coverage. - Persistent weather pattern will continue through mid week with above normal temperatures and humidity. - Precipitation chances return Thursday ahead of a Pacific cold front that will reach the area late in the week. && .SHORT TERM... (Today through Thursday night) Issued at 552 PM CST Tue Nov 18 2025 Persistence forecast will maintain over much of the short term period. Warm and humid conditions with no rain chances for the rest of today, Wednesday and into early Thursday beneath upper level high pressure ridging. An upper wave moving across the central US, along with an attendant cool front, will start moving towards the southeast late Wednesday with a much more robust organization into Thursday afternoon. With the moist airmass in place, falling heights could easily assist with the generation of cloud cover and light rainfall during the afternoon. The greatest bulk of rainfall still exists in the longterm. Temperatures in the lower 80s are ongoing today and are expected Wednesday. Not expecting any broken temperature records, just warm and muggy. 11/Calhoun && .LONG TERM... (Friday through Tuesday) Issued at 552 PM CST Tue Nov 18 2025 The surface low bringing on this period of disturbed weather will move north of the region Friday into Saturday. Upper wave appears to eject very swiftly, with very little forcing left behind with the frontal boundary. This should result in a slowing progression from west to east, and combined with the anomalously moist airmass in place, there could be very efficient rainfall in Deep Southeast Texas and southwest Louisiana. The front slowly lays over into the Louisiana coastline into Saturday with lingering rainfall occurring along its axis. By the start of next week, the next upper low appears to move into the southwest US. The return flow generated will lift the warm sector north again with low end rainfall chances in accompaniment Monday into Tuesday. 11 && .AVIATION...
