815 FXUS64 KLCH 111703 AFDLCH Area Forecast Discussion National Weather Service Lake Charles LA 1203 PM CDT Sun Aug 11 2024 ...New AVIATION... .SHORT TERM... (Today through Tuesday night) Issued at 335 AM CDT Sun Aug 11 2024 Early morning sfc analysis shows the area under the influence of high pressure centered over the mid-MS Valley which is maintaining a light nerly flow over the area. Meanwhile, our old stationary boundary continues to meander near the coast. Water vapor imagery shows mid/upper-level ridging lingering in place from the Desert SW esewd to the wrn Gulf region while a weak wave is noted over the n-cntl Gulf. Sfc obs/satellite imagery showed clear skies across the region. Regional 88Ds were PPINE. Expecting one more dry, warm, less muggy day across the forecast area today. Wouldn`t be totally shocked to see a shower or two develop around the Morgan City/Amelia area with heating this afternoon courtesy of the least capping (per forecast soundings around that area) along with the weak wave passing just offshore...but chances look low enough for now to leave out rain wording for now. Highs today are progged to run a degree or two warmer than yesterday, but combined with lower dewpoints generally in the upper 60s/lower 70s, heat index values are again expected to stay below heat advisory criteria. Monday sees small POPs encroaching the srn 1/2 of the forecast area as the boundary inches inland, the erly wave weakens the ridge and a sea breeze boundary looks to develop. Temperatures continue to warm by a degree or two, with readings nipping at triple digits over the nern zones. However despite dewpoints inching upward as well, max apparent temps stay below advisory criteria for one more day. Tuesday looks like a general repeat of Monday, albeit even warmer/muggier...and a heat advisory may be needed for portions of the area. 25 && .LONG TERM... (Wednesday through Sunday) Issued at 335 AM CDT Sun Aug 11 2024 Small afternoon POPs linger through the end of the week as the ridge axis stays shunted off a bit to the north, with daytime heating and sea breeze/resultant boundary development being the main convective drivers. Temps/dewpoints will continue a slow climb which should lead to apparent temps again reaching advisory criteria over portions of the forecast area through the end of the period. 25 && .AVIATION... (18Z TAFS) Issued at 1202 PM CDT Sun Aug 11 2024 Mostly clear skies along with light and variable winds will continue area-wide through the period. No deviations from VFR conditions are expected. && .MARINE... Issued at 335 AM CDT Sun Aug 11 2024 Mainly light/somewhat variable winds are expected over the coastal waters for the next couple of days with the sfc front meandering over the nwrn Gulf. Thereafter as the front lifts back nwd, a srly flow will return. No headlines are expected on the CWF through the next several days. 25 && .PRELIMINARY POINT TEMPS/POPS...
