Area Forecast Discussion National Weather Service Lake Charles LA 1227 PM CDT Fri Sep 15 2023 ...New AVIATION... .SHORT TERM... (Today through Sunday night) Issued at 344 AM CDT Fri Sep 15 2023 Synoptic pattern in place across the region has changed little since yesterday, featuring westerly flow aloft with a stationary front sitting just offshore, stretching from the Bolivar Peninsula eastward across the coastal waters. Isolated convection has developed in the vicinity of the boundary over the past couple of hours, and this activity is expected to remain over the coastal waters over the next several hours. Latest CAM guidance is not very enthusiastic about rain chances inland today, pointing toward isolated late morning and afternoon convection across SE TX and mainly along/S of I-10 in southern LA. Toward early evening, SE propagation of ongoing convection across the TX panhandle could allow it to reach SE TX just as it falls apart, which is depicted by the HREF. With this in mind, NBM PoPs consequently looked quite overdone, so tempered them down by blending in a mix of the aforementioned CAM guidance. With the decrease in convective activity and less in the way of cloud cover than yesterday, forecast highs are expected to climb into the upper 80s to lower 90s. Fairly close to seasonal normals. This general synoptic pattern will stick around for one more day, until a digging ERN CONUS trof yields a deep NW flow that will rid us of the stationary front and usher in a drier airmass SAT night into SUN. 13 && .LONG TERM... (Monday through Friday) Issued at 344 AM CDT Fri Sep 15 2023 The long term portion of the forecast period begins with fairly pleasant weather as the old cold front is forecast to be beyond the coastal waters by Monday. Meanwhile, the region is progged to be on the back side of an ern CONUS mid/upper-level trof, with its nwrly flow further drying the airmass over the area. After morning lows in the 60s areawide, highs will still be a bit warm (generally lower 90s), although humidity values are looking to be really low (20s or lower 30s percent). These dry conditions are expected to linger through Tuesday, although the with the old frontal boundary progged to push back inland as a warm front, minimum RH values will be a little higher. By Wednesday, small rain chances to portions of the forecast area (mainly the wrn 2/3 and all coastal areas) as another significant shortwave approaches the region, while low-level moistening continues behind the sfc frontal boundary which should be washing out over the region. Thursday looks fairly similar to Wednesday as the initial shortwave departs the region, while a 2nd disturbance then approaches. 25 && .AVIATION... (18Z TAFS) Issued at 1225 PM CDT Fri Sep 15 2023 Some convection ongoing across SE TX may affect BPT and LCH through the afternoon hours. Elsewhere, no precip is expected today. Otherwise, no issues through the period with light and variable winds and VFR ceilings continue at all terminals. 17 && .MARINE... Issued at 344 AM CDT Fri Sep 15 2023 A weak stationary front will continue to meander near the coast through the next couple of days resulting in mainly light offshore flow and low seas. The proximity of the front over the coastal waters will maintain scattered showers and thunderstorms today through Saturday as well. Winds will remain offshore through the weekend, gradually returning to an onshore flow again on Monday. 13 && .CLIMATE... Issued at 350 AM CDT Fri Sep 15 2023 ...AND THEN, THERE WAS ONE...
