| Synopsis for Lower Atchafalaya River LA to High Island TX out 60 NM including Sabine and Calcasieu Lakes and Vermilion Bay: GMZ400 343 PM CST Sun Jan 16 2022 Northwest winds will continue to subside the rest of the afternoon and into this evening, though the persistent offshore flow coupled with low astronomical tide levels will still yield low water conditions on the coastal lakes and bays. Surface high pressure will traverse the region on Monday, with an onshore flow developing in its wake. This southerly flow will continue until another frontal passage Wednesday night. |
| Area Forecast Discussion National Weather Service Lake Charles LA 430pm CST Sunday Jan 16 2022 00Z TAFS /issued 347pm CST Sunday Jan 16 2022/ Short Term - Tonight Through Tuesday Upper low now over the SE CONUS and continuing to pull away from the region, with wrap around clouds now well east of the area as a deeper plume of MSTR spreads in from the west. NW winds are still a little gusty, but will continue to settle down this evening as the gradient relaxes and weak SFC high pressure to the west slides eastward. Good though not ideal radiational cooling is expected tonight, and lows will once again drop into the lower/mid 30s. Another SFC high dropping south from the Plains will traverse the area tomorrow with NW flow prevailing aloft. A sunny and seasonably mild afternoon is forecast, with highs reaching the lower to perhaps mid 60s. As the SFC high shifts east of the area tomorrow night, an initially light return southerly flow will become established, becoming more modest through the day TUE between the departing high and an area of low pressure over the Southern Plains. Amid this warm air/moisture advection regime, lows TUE morning near or just above normal are expected, giving way to high temperatures TUE that will climb well above normal into the upper 60s to lower 70s. Long Term - Wednesday Through Sunday The long term period has not changed significantly since yesterday. It will be denoted by a cold front that will be moving through the area Wednesday into Thursday which will bring much cooler air. Wednesday will be warm with onshore flow present prior to the arrival of the cold front. The warm temperatures, moisture with onshore flow, and forced uplift from the front will mean there will be chances for showers and thunderstorms Wednesday into Thursday. Much cooler air will be arriving post frontal. Cooler temperatures will be expected to persist to the end of the period with an area of high pressure in the region which will help keep northerly flow and prevent a significant warm up. Shortwave energy will be expected to move across the southwestern U.S. and enter our area over the weekend. The significant cloud cover expected along with still mostly northerly winds will mean temperatures will remain below average late in the period. NBM is indicating continued chances for precipitation post frontal Thursday into the weekend. However, ECMWF (European Centre for Medium-Range Weather Forecasts) is not showing precipitation post frontal and GFS is only showing very modest amounts over the weekend. Given that northerly flow will persist and moisture will be expected to be low inland, NBM Probability of Precipitation and WPC Quantitative Precipitation Forecast were reduced post frontal Thursday into the weekend. Although there will be a chance for snow post frontal, areas that are most likely to see any precipitation will be areas that are expected to be above freezing (near the coast and offshore). Chances for precipitation will be low post frontal regardless. 55 Marine Northwest winds will continue to subside the rest of the afternoon and into this evening, though the persistent offshore flow coupled with low astronomical tide levels will still yield low water conditions on the coastal lakes and bays. Surface high pressure will traverse the region on Monday, with an onshore flow developing in its wake. This southerly flow will continue until another frontal passage Wednesday night. 13 NOAA Lake Charles LA Office: Watches - Warnings - Advisories LA...None. TX...None.
