Area Forecast Discussion National Weather Service Lake Charles LA 350 PM CDT Thu Jun 22 2023 ...New SHORT TERM, LONG TERM, MARINE... .SHORT TERM... (Tonight through Saturday night) Issued at 320 PM CDT Thu Jun 22 2023 Convection continues to blossom across the region this afternoon in response to a combination of a quasistationary surface boundary which continues to meander across the region and an upper level shortwave pushing across the area from Northwest to Southeast as it wraps around the sprawling longwave over the Southeastern U.S. Expect this activity to continue through the mid evening before waning by late evening as the upper level support exits the region. High rainfall rates are already being observed with some of these storms and periods of torrential rainfall will remain possible that could lead to some nuisance flooding. Guidance is in good agreement on nocturnal convective redevelopment offshore early Friday morning with this activity gradually lifting back inland by mid morning. Another upper level shortwave is progged to slide across the area within the broader northwesterly flow aloft Friday afternoon which will result in another round of scattered to numerous storms capable of torrential rainfall and frequent lightning. This should once again hold afternoon highs in the upper 80s to lower 90s and apparent temperatures near 100. The persistent upper level ridge over Northern Mexico will begin to build back across Southeast Texas by Saturday putting a lid on the daily convection and allowing afternoon highs to creep back upward. Isolated to widely scattered afternoon thunderstorms will still be possible Saturday afternoon across South Central Louisiana where the influence of the building ridge will be less pronounced, but don't expect these to amount to nearly as much as is being seen today or tomorrow. As of now, forecast apparent temperatures are on the fringe of advisory criteria across the Texas counties, but should remain below criteria in Louisiana. Jones && .LONG TERM... (Sunday through next Wednesday) Issued at 320 PM CDT Thu Jun 22 2023 No real change to the long term portion of the forecast this afternoon, as several hot and dry days are on tap. Aloft, a large high pressure ridge situated over Mexico/Texas will gradually expand eastward across the CWA through the first half of the week. At the surface, weak high pressure over the SE US/Gulf of Mexico will provide a persistent SWrly flow through the week, allowing dewpoints/moisture to remain elevated. Ridging expanding overhead aloft will put a cap on any convection through the long term period, with near zero rain chances on tap each day. At the same time, low level moisture will continue to pool overhead. This will, unfortunately, result in several very hot and humid days with afternoon highs gradually increasing each day. Sun, highs will top out in the low to mid 90s along and south of I-10 and in the upper 90s further inland. Mon to Thurs, inland highs will reach into the upper 90s to lower 100s, and in the mid to upper 90s further south. These temps combined with dewpoints in the mid 70s to near 80 will bring about heat indices in the 107-117 degrees range. Heat Advisories as well as Excessive Heat Warnings will once again be needed each day for most, if not all, of the forecast area. 17 && .AVIATION... (18Z TAFS) Issued at 1225 PM CDT Thu Jun 22 2023 Expect increasing thunderstorms across the region through the afternoon in response to a weak, quasistationary frontal boundary meandering across the region and a weak upper level disturbance traversing the area. Activity will wane through the evening with little activity expected overnight. Another round of scattered convection is expected to initialize Friday morning. Away from storms, VFR conditions will prevail through the period along with light, variable winds. Jones && .MARINE... Issued at 320 PM CDT Thu Jun 22 2023 Light onshore flow and low seas will prevail through the period. Scattered showers and thunderstorms will continue this afternoon, tonight and through Friday. The mid to upper ridge over Mexico and Texas expected to strengthen and move slowly eastward this weekend into most of next week, gradually lower chances of showers and thunderstorms. && .PRELIMINARY POINT TEMPS/POPS...
