| Area Forecast Discussion National Weather Service Lake Charles LA 1058pm CST Sunday Dec 3 2023 .SHORT TERM... (Tonight through Tuesday night) Issued at 325pm CST Sunday Dec 3 2023 Afternoon surface analysis shows weak high pressure overhead providing a light W to SW flow along with some slightly drier air at the surface (when compared to the last couple of days). Aloft, a broad longwave trough extends from the Great Lakes to north Mexico, with a SWrly flow overhead. This has resulted in a steady stream of mid to high clouds into the region today, keeping temps around 70 degrees this afternoon. Tonight into tomorrow, the mid/upper level trough will gradually make its way eastward, eventually pushing a weak cold front through the forecast area sometime around mid-day tomorrow. This frontal passage will be mainly noticeable by a northerly wind shift, which will bring another shot of drier air into the region. At the same time, the progression of the upper level trough will result in winds aloft shifting W and eventually NW overhead. The combination of NW winds aloft and N winds at the surface will bring a pleasant end to the short term period, with skies largely clearing out and dewpoints in the mid 30s to low 40s. Temperature wise, lows tonight will be slightly above average in the mid 40s to low 50s. Tomorrow night and Tuesday night, drier air will allow temps to fall into the lower 40s area-wide. Highs will run near average, topping out in the mid 60s to low 70s both tomorrow and Tuesday. 17 Long Term (Wednesday through next Saturday) Issued at 325pm CST Sunday Dec 3 2023 The long term kicks off with an upper level ridge over TX, building eastward into our area and a surface high over the central and southern plains. Winds will be out of the north for a short moment before returning out of the south as the surface high moves off to the east on Thursday. From there going into the weekend, we will see a warming trend with MaxTs going from the lower to mid 60s to the mid 70s and MinTs going from the mid 30s / lower 40s to the 50s / lower 60s. Dewpoints will also be on the rise with mid 30s in the middle of the work week to lower 60s by Friday. While the models seem to agree on a system moving into the area over the weekend, the timing is off. The GFS (Global Forecast System) has the front and any associated precipitation moving into the area by Saturday morning and moving out that night while the EURO has showers moving in mid to late Saturday then clearing out by Sunday afternoon. Despite the timing difference, cooler and drier air will be moving in after the front leaving us with temperatures cooler than climatological norms. Stigger/87 Marine Issued at 300pm CST Sunday Dec 3 2023 Light and variable winds and low seas will prevail through Tuesday. Drier air has filtered into the region today and will continue to do so through the start of the week, which should keep marine fog at bay for the time being. Late Tuesday, a cold front is expected to move through the coastal waters, resulting in a brief offshore flow and slightly stronger winds through Wednesday. Onshore flow then resumes by Thursday as the surface high moves east of the area. NOAA Lake Charles LA Office: Watches - Warnings - Advisories LA...None. TX...None. GM...None. |
