981 FXUS64 KLCH 241540 AFDLCH Area Forecast Discussion National Weather Service Lake Charles LA 1040 AM CDT Fri May 24 2024 ...New UPDATE... .UPDATE... Issued at 1038 AM CDT Fri May 24 2024 Southerly winds will bring in low level Gulf moisture and help make things very humid. However, enough capping around that we should not see any significant shower activity. Current forecast is on track and no changes needed at this time. Rua && .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... (12Z TAFS) Issued at 546 AM CDT Fri May 24 2024 BR and MVFR/IFR CIGs this morning will transition to MVFR/VFR CIGs this afternoon. Southerly winds around 14 kts this afternoon. MVFR/IFR CIGs return by this evening. && .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...
