111 FXUS64 KLCH 240924 AFDLCH Area Forecast Discussion National Weather Service Lake Charles LA 424 AM CDT Fri May 24 2024 ...New SHORT TERM, LONG TERM, AVIATION, MARINE... .SHORT TERM... (Today through Sunday night) Issued at 311 AM CDT Fri May 24 2024 Expect a couple sprinkles or even an isolated shower with moist onshore flow this morning. However it will not amount to much. Were looking at another hot and humid day with highs in the middle/upper 80s coast and lower 90s inland. Heat indices will range from 98-103 degrees. Expect very similar conditions as we move into the weekend with highs in the upper 80s coast and lower/middle 90s inland. With continued light to moderate onshore flow, heat indices will range from 98-104 degrees. && .LONG TERM... (Monday through Friday) Issued at 311 AM CDT Fri May 24 2024 Next week will start off hot and humid, with high temperatures in the mid-90s across the region. Central Louisiana and interior southeast Texas could reach the upper 90s with highs around 97 degrees. This is mainly due to the high pressure that will extend across the region from the east coast. This same ridge will also cause our winds to be onshore, pushing high levels of low-level moisture far inland. This ridge is strong for this time of year, with our heights in the 97th percentile and 850 temperatures above the 99th percentile. The apparent temperature will be greatest in southeast Texas, with values rising above 105. The experimental heat risk tool supports this by placing a swath of our area under a major heat risk. Temperatures will improve on Tuesday as a boundary moves across the region. Models are showing a very diffuse and weak front that will bring sporadic rainfall. For now, we only have PoPs around 20%. Atmospheric dynamics still look marginal for this event so, as of now, we don`t expect to see widespread thunderstorms or severe weather. Conditions could change and we could see PoPs increase or even for thunderstorms to become widespread so make sure to keep an eye on the forecast. With the passage of this system will come a cooler and drier airmass, which will drop our temperatures back into the upper 80s to the low 90s. 14/Slaughter && .AVIATION... (06Z TAFS) Issued at 311 AM CDT Fri May 24 2024 Some clouds are lingering overtop the area; the remnants of convective blowoff. The expectation is for some low clouds to continue developing with MVFR ceilings to prevail through the early morning. Ground fog will develop at most terminals with VIS to 5SM expected. After 15 or 16Z, the typical diurnal pattern returns with breezy south winds and high cloud ceilings. && .MARINE... Issued at 311 AM CDT Fri May 24 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...
