228 FXUS64 KLCH 232352 AFDLCH Area Forecast Discussion National Weather Service Lake Charles LA 652 PM CDT Tue Apr 23 2024 ...New AVIATION... .SHORT TERM... (Tonight through Thursday night) Issued at 335 PM CDT Tue Apr 23 2024 Highs warmed into the middle and upper 70s today with onshore flow across the area. This warming trend will continue into Wed/Thu with highs into the lower and middle 80s. A tightening pressure gradient will also increase SFC wind speeds across the area beginning Thursday with some gust around 20-25 mph. There could also be some fog tonight, but probabilities are rather low at this time. The area most favored is SETX, but almost anywhere in the CWA could see some briefly around sunrise. Nothing looks too dense, but it is worth noting. && .LONG TERM... (Friday through next Monday) Issued at 335 PM CDT Tue Apr 23 2024 Main story in the long term will be the tightening of the pressure gradient even further as high pressure slides east. This will produce moderate to strong onshore flow late week into early next week, with the strongest Friday and/or Saturday. Wind advs may be needed as we approach the end of the week. Temperatures from Thursday into the weekend will remain in the middle 80s each afternoon. By Sunday afternoon, the upper level ridge looks to shift a little to the east. This will allow for a short wave to cut into the ridge and move through the region late Sunday into Monday. The weakness aloft and plenty of Gulf moisture will allow for a chance of showers and thunderstorms during that time period. && .AVIATION... (00Z TAFS) Issued at 652 PM CDT Tue Apr 23 2024 Some low to mid level clouds have moved into the region on southerly winds. A brief period of high MVFR ceilings will continue through the next few hours, but ultimately expect low VFR ceilings overnight. With the return of moisture comes some fog development overnight. Some lowered VIS to around 5 SM is expected between 06 and 12Z tonight. After 14Z, expect light to moderate south-southeast winds through the remainder of the day. 11/Calhoun && .MARINE... Issued at 335 PM CDT Tue Apr 23 2024 Onshore flow will remain light until the end of the week. During this time waves will be less than four feet. Starting on Thursday winds will start to increase becoming moderate to strong. Waves will also build in the outer waters possibly reaching 7 feet or more by Friday morning. Lakes and bays will be rough to very rough conditions. && .PRELIMINARY POINT TEMPS/POPS...
