217 FXUS64 KLCH 231715 AFDLCH Area Forecast Discussion National Weather Service Lake Charles LA 1215 PM CDT Thu May 23 2024 ...New AVIATION... .SHORT TERM... (Today through Saturday night) Issued at 247 AM CDT Thu May 23 2024 The region remains between an area of high pressure just off the Atlantic coast and a cold front that stretches from West Texas to the Great Lakes. This continues to provide a humid south flow off the gulf. Aloft a ridge is centered over Mexico and stretches north to the gulf coast. A pair of upper lows are moving across the northern sections of the country within a larger trough over most of the CONUS. Smaller upper disturbances are passing just north of the area along the base of the larger trough. Thunderstorms traversed North LA this past afternoon with a passing upper disturbance. A few showers have worked into the northern zones early this morning, however this convection is expected to exit the region through the next few hours. With the upper ridge continuing to influence the area`s wx, another hot and humid and generally dry day is anticipated. A few light showers can not be completely be ruled out during the afternoon as daytime heating occurs, however the ridge will keep any convection greatly limited. Another disturbance may pass the region to the north this afternoon with a few showers or storms potentially working into the lakes region to Cen LA again this evening or tonight. The upper ridge is expected to build north Friday and Saturday. Temperatures will gradually increase and rain chances will be farther suppressed. && .LONG TERM... (Sunday through Thursday) Issued at 247 AM CDT Thu May 23 2024 Strong ridge of high pressure peaks late weekend into early next with daytime highs in the middle 90s across the region. This will yield heat indices 99-104 degrees Sunday and Monday. Heat indices could reach 105 degrees on Monday as a frontal bndry approaches the region. Frontal bndry moves through Monday night into Tuesday dropping highs back into the upper 80s and lower 90s. TDs will also lower a bit, giving a short reprieve from the hot/humid conditions. As the front slides across the area, isolated showers/storms will also be possible. Thereafter, daytime highs stay in the upper 80s to lower 90s with a return of light onshore flow. 78 && .AVIATION... (18Z TAFS) Issued at 1213 PM CDT Thu May 23 2024 MVFR to VFR ceilings, breezy southerly winds, and occasional hazy conditions can be expected through the afternoon. Tonight, winds will relax a bit while ceilings will continue to waffle between VFR and MVFR. Hazy and/or foggy conditions will be possible again through the morning hours. Winds will again become breezy with more frequent gusts by the late morning hours tomorrow, while ceilings should become VFR area-wide. 17 && .MARINE... Issued at 247 AM CDT Thu May 23 2024 Moderate onshore flow is expected to prevail into the weekend as a tightened pressure gradient between surface high pressure to the east and a series of low pressure systems across the Plains continues. Rain chances should remain low although an isolated light shower or two cannot be ruled out. && .PRELIMINARY POINT TEMPS/POPS...
