NWS Lake Charles, LA wrote its last area forecast discussion before the first event at Aug 3, 5:28 AM CST, 5 hours 26 minutes earlier.
Area Forecast Discussion National Weather Service Lake Charles LA 628 AM CDT Wed Aug 3 2022 .DISCUSSION... For the 08/03/2022 1200 UTC TAF package. && .AVIATION... Some low clouds and patchy fog have developed over central Louisiana and this is affecting the KAEX terminal with the possibility of IFR/MVFR conditions until about 03/14Z. A cluster of nocturnal showers and thunderstorms are noted over Vermilion Bay. Some of this activity may build up toward KARA and will have VCSH to start out the forecast for that site. For today, numerous showers and thunderstorms are expected east of a KAEX to KLCH line. Therefore, KARA and KLFT should have the highest probability of seeing thunderstorms, especially after 03/18Z. Away from the storms, VFR conditions will prevail. Rua && .PREV DISCUSSION... /issued 415 AM CDT Wed Aug 3 2022/ SHORT TERM [Today through Friday]... The forecast during this period will be influenced by what a mid level low/inverted trough feature located around the middle Gulf coast/southeast Louisiana area currently. The inverted trough is expected to become more well defined and move gradually westward and into south central Louisiana on Thursday and southwest Louisiana/southeast Texas on Friday. Nocturnal shower activity is currently occurring off the south central Louisiana coast. This is where the better moisture is located and should be a foretelling of where the higher rain chances will be later on the morning into the afternoon and that is over south central Louisiana and northward between the I-49 corridor to the Atchafalaya Basin. Pops will gradually lower as you head to the west. Upper level ridging is noted to mainly hold over southeast Texas, so that area will see limited convection and hotter conditions. As the inverted trough moves into south central Louisiana on Thursday, numerous showers and storms can be expected east of a Leesville to Lake Charles line anytime during the day, and activity west of there gradually increasing in the afternoon. Then on Friday the convective activity will be concentrated more into southwest Louisiana and southeast Texas, with convection beginning early in the day. PWAT will be over 2.25 inches at times with the inverted trough and with favorable conditions for precipitation efficient storms, some high rainfall rates between 1 to 3 inches per hour, will be possible. This will bring about the potential for some locally heavy rainfall that may lead to localized urban street type flooding. Therefore, WPC has outlined southwest and south central Louisiana in a Marginal Risk (risk level 1 out of 4) of Excessive Rainfall for today and Thursday, and for southeast Texas and southwest Louisiana on Friday. Rua LONG TERM [Saturday through Tuesday]... With the inverted upper level trof moving inland over eastern Texas where it will dissipate by late Saturday, the region will revert back to the pattern seen through much of the last couple of weeks. Weak ridging will build back in across east Texas while a fairly expansive tropical airmass will remain in place across the northern gulf. Scattered to numerous, diurnally driven, storms will develop each day by late morning and continue through early evening. More widespread storms are expected across south central Louisiana where the influence of the upper ridging will be less pronounced. Guidance is depicting some form of another inverted upper trof developing in the northeastern gulf by the middle of next week, but there is little spatial or temporal continuity with it. Any synoptic support in the very tropical airmass will elevate PoPs further and the forecast will continue to reflect PoPs above climatological normals through mid week. Jones 66 MARINE... Surface high pressure ridging across the northern Gulf of Mexico will maintain a light to occasionally moderate onshore flow through the end of the week into the weekend. An upper level disturbance moving across the northwest Gulf will help provide numerous showers and thunderstorms through the end of the week. Rua && .LCH WATCHES/WARNINGS/ADVISORIES... LA...None.
