156 FXUS64 KLCH 040433 AFDLCH Area Forecast Discussion National Weather Service Lake Charles LA 1133 PM CDT Fri May 3 2024 ...New AVIATION... .SHORT TERM... (Tonight through Sunday night) Issued at 330 PM CDT Fri May 3 2024 Area radar this afternoon shows scattered showers and thunderstorms spreading across the region from the west. Most of today`s precip has fallen across SE TX and SW LA, with area mesonet stations showing around 0.75-2.00" of rain has fallen in these regions. CAMs have largely handled today`s system poorly however, the HRRR seems to have gotten a better handle on it over the last couple of runs and continues to show most of this activity ending between 6 and 8 PM this evening. Overnight, dry weather is expected along with another round of patchy fog, especially across those areas that saw a good bit of rain today. Moving into the weekend, rain chances continue. Tomorrow, another shortwave is expected to pass overhead and initialize scattered showers by the late morning hours. POPs tomorrow are only in the 20-40% range, with better chances north of I-10, and overall coverage should be much less than the last couple of days. Rain chances then ramp up again for the second half of the weekend as a second, more robust, shortwave slides overhead and passes a bit further to the south that Saturday`s shortwave. This may bring a similar set up to today`s convection, with elevated rain chances in the 40-60% range on tap area-wide. Fortunately, no severe weather is anticipated this weekend however, we will have to keep an eye on the flooding risk as much of the forecast area has already received significant rainfall over the last couple of days. Temperature wise, we will see near seasonal daytime highs over the weekend, warming into the low to mid 80s area-wide both days. Overnight, lows will continue to fall into the upper 60s inland and low to mid 70s along and south of I-10. 17 && .LONG TERM... (Monday through next Thursday) Issued at 330 PM CDT Fri May 3 2024 As we head into the work week small rain chances continue for Monday followed by a reprieve from the wet weather through the mid-week. POPs on Monday are only around 15-30% at best, with mainly isolated afternoon activity anticipated. Tuesday through Thursday a drier pattern is expected as a weak midlevel ridge builds over the Gulf Coast and offers a bit of drier air aloft to keep showers at bay. Finally by Friday we may see a return of shower activity as some long range models are now pointing to a weak frontal passage. This is still a ways out however, and changes to the progression of this front are likely. Temperature wise next week will bring a gradual warming trend with highs on Mon in the mid 80s warming into the mid to upper 80s on Tuesday and into the upper 80s to lower 90s from Wednesday and beyond. Overnight, lows in the low to mid 70s can be expected. 17 && .AVIATION... (06Z TAFS) Issued at 1127 PM CDT Fri May 3 2024 With the exception of KARA, which has some low clouds and ceilings at MVFR conditions, the terminals are starting out at VFR levels from high level clouds. Extensive high level cloudiness as the result of convective blow-off from central/west Texas moving over the forecast area. This may help reduce cooling and help keep or delay the very low clouds and patchy fog from forming until after 04/09z. Still expect at least MVFR conditions at all terminals from the low ceilings and patchy fog. Not looking at any disturbances moving into the region tonight and with a drier airmass based on the 04/00z upper air sounding from KLCH, not expecting any shower activity overnight. On Saturday, more stable conditions look to be in store. However, still enough moisture along with daytime heating to allow for isolated showers or storms to develop and will only mention VCSH and VCTS for terminals through the day. Rua && .MARINE... Issued at 330 PM CDT Fri May 3 2024 Scattered showers and thunderstorms will continue into this evening across the coastal waters and coastal lakes/bays. In addition, moderate onshore flow will also persist, and small craft should continue to exercise caution through tonight. Tonight, rain will end however, fog is expected to develop closer to sunrise especially along and near the coastline. Light onshore flow and low seas will prevail through the rest of the upcoming week. && .PRELIMINARY POINT TEMPS/POPS...
