008 FXUS64 KLCH 261725 AFDLCH Area Forecast Discussion National Weather Service Lake Charles LA 1225 PM CDT Thu Jun 26 2025 ...New AVIATION... .KEY MESSAGES... - An upper level ridge will be near the area today helping to bring about slightly lower rain chances for the afternoon showers and storms, while the typical summer heat persists with max afternoon heat index values from 100 to 105 degrees. - From the weekend into early next week, the forecast area will be between a ridge to the west and trough to the east. Expect typical summertime weather with a daily chance of mainly afternoon showers and thunderstorms to go along with the usual hot and humid conditions. && .SHORT TERM... (Today through Saturday night) Issued at 217 AM CDT Thu Jun 26 2025 Radar is as quiet as it has been over the past few days as not too much in the way of nocturnal shower activity. This may foretell a less active day as far as showers and storms go. An upper level ridge has nudged to the west and over the Tennessee Valley. As the ridge continues to retrograde to the west it will continue to push deeper moisture off to the west with it being replaced by some drier and lower PWAT air. Therefore, looking at lower rain chances for mainly afternoon showers and thunderstorms. CAMs show activity will be mainly isolated to widely scattered during max heating and with any seabreeze boundary. For Friday into the Saturday, the upper level ridge will become more flat and weaker. With low level southerly flow continuing, low level moisture and humid conditions will occur. Daytime heating and seabreeze boundaries should allow for scattered afternoon showers and thunderstorms to develop. Looks like typical summertime heat away from the storms with max afternoon heat index values expected to range between 100F and 105F degrees. Rua && .LONG TERM... (Sunday through Thursday) Issued at 222 AM CDT Thu Jun 26 2025 For the first part of next week the pattern is setting up in the low levels with a continuation of the high off the southeast U.S. coast ridging into the forecast area. This will keep mainly southerly low level flow keeping around Gulf moisture and humid conditions. Meanwhile, in the upper levels, general pattern will see a ridge to the west of the forecast area and a trough to the east. Therefore, looks like the usual daily chance of the diurnal and seabreeze driven showers and storms mainly during the afternoon hours. Rain chances will slightly higher over eastern portions closer to the trough and a little lower over southeast Texas as that area will be closer to the ridge. Rua && .AVIATION... (18Z TAFS) Issued at 1223 PM CDT Thu Jun 26 2025 Isolated convection has begun to develop across SE TX, and may expand across south LA later this afternoon. Overall, rain chances are rather low today and most terminals will not see precip, therefore just kept VCTS in the I-10 tafs for the possibility of isolated convection. Otherwise, light winds and VFR CIGs/VIS continue through the forecast period. && .MARINE... Issued at 207 AM CDT Thu Jun 26 2025 A surface high off the southeast U.S. coast will continue to ridge across the northern Gulf and into the coastal through the weekend into early next week. The result will be mainly light southeast to south winds and relative low seas. There will be a daily chance of seeing scattered showers and thunderstorms. && .FIRE WEATHER... Issued at 205 AM CDT Thu Jun 26 2025 An upper level ridge will help reduce rain chances today. Despite this, light southerly flow will bring in low level moisture keeping things on the humid side with minimum afternoon relative humidity values around 50 across upper southeast Texas as well as central Louisiana and around 60 percent along the I-10 corridor to the coast. Mainly typical summertime pattern into the weekend with a daily chance for afternoon showers and thunderstorms to go along with hot and humid days and muggy nights. && .PRELIMINARY POINT TEMPS/POPS...
