741 FXUS64 KLCH 251513 AFDLCH Area Forecast Discussion National Weather Service Lake Charles LA 1013 AM CDT Sat May 25 2024 ...New UPDATE... .UPDATE... Issued at 1010 AM CDT Sat May 25 2024 Another hot and humid day across the forecast area. Southerly winds will keep bringing in low level Gulf moisture allowing for high dew points and high humidity. Enough capping in place that there shouldn`t be any significant shower activity. On-going forecast is on track and no changes needed at this time. Rua && .SHORT TERM... (Today through Monday night) Issued at 252 AM CDT Sat May 25 2024 High pressure will continue to dominate our weather pattern this Memorial Day weekend. Weak but steady south to southwest flow will continue to pull in the tropical airmass and high humidity. Overhead, the high pressure will also suppress convection leading to clear skies and maximizing our daytime heating. The unseasonable warm temperatures will lead to highs in the low to mid 90s. Monday will be the hottest day of the forecast period with temperatures in the mid to upper 90s. Apparent temperatures will soar above 100 degrees and will approach Heat Advisory levels of 108 degrees. Monday evening a diffuse cold front will push through the region and bring a dry continental airmass. Leading to much nicer conditions to start the extended forecast. && .LONG TERM... (Tuesday through Saturday) Issued at 252 AM CDT Sat May 25 2024 Large mid to upper level troughs over the Western and Eastern U.S. with weak ridging aloft over Mexico will keep a west northwest flow aloft over the region Tuesday through Wednesday. This should allow for a weak frontal boundary to move through the area Tuesday afternoon. Expect another hot afternoon with highs in the lower to mid 90s, with heat index values in the lower 100s. Isolated showers and thunderstorms along and ahead of the frontal boundary. Slightly cooler & drier air expected Tuesday night and Wednesday should bring overnight lows back into the upper 60s to lower 70s and afternoon highs in the upper 80s to near 90 on Wednesday. For Thursday through Saturday, whatever`s left of the frontal boundary expected to wash out, with southeast winds expected to resume as surface high pressure prevails over the SE U.S. Weak upper level disturbances in the northwest flow aloft over our region likely to keep isolated to scattered afternoon showers and thunderstorms, with blended guidance showing consistent 20-30% each afternoon. Overnight lows near 70/lower 70s north of I-10, mid 70s further south. Afternoon highs in the upper 80s to near 90. 08/DML && .AVIATION... (12Z TAFS) Issued at 623 AM CDT Sat May 25 2024 Patchy fog will quickly fade away with the sunrise. As the fog lifts we should see VFR conditions for most of the TAF period with occasional MVFR ceilings. Winds will be from the south around 10 to 15 knots with some gusts up to 20 knots near the coast. Overnight MVFR ceilings will return. && .MARINE... Issued at 252 AM CDT Sat May 25 2024 Surface high pressure continues to dominate our weather pattern. On shore flow will continue for the next several days with winds around 10 to 15 knots. Saturday night winds will increase approaching 20 knots and a caution statement for small craft will go into effect. Waves will increase with the winds reaching 6 feet Saturday and Sunday then decreasing to 4 feet on Monday.
