| Area Forecast Discussion National Weather Service New Orleans LA 333pm CST Fri Dec 8 2023 Long Term (Monday through Thursday night) Issued at 252pm CST Fri Dec 8 2023 By Monday the back side of the current troughiness is moving into slight ridging and southern branch flow. A surface high moves quickly across the area in the lea of the trough. Toward mid-week a low moves into the western US and provides a path for moisture return over the northern Gulf and into TX. By the end of the week there are some minor differences in global model solutions, but overall the low pressure moves slowly east while the ridging builds in amplitude over the eastern US. All this results in chilly temps warming slightly through the end of the week and little to no rain. Early in the week we will have lots of sun, but will transition as the week progresses to seeing partly to mostly cloudy skies. Winds early in the week will be dominated by the surface high and generally light and variable followed by a shift to light and easterly for the remainder of the period. Of most note may be daytime RHs that may dip into the 40% range early in the week, but should increase as the additional moisture returns increase mid to late week. NBM values are accepted, especially since there is very little variability in the ensemble members. However, slight downward adjustments to lows were made in cold air drainage areas on Monday and Tuesday. Marine Issued at 252pm CST Fri Dec 8 2023 A rather rough period of weather is expected over the marine zones through the middle of next week as a series of weather systems impacts the northern Gulf. Initially, a strong cold front will sweep through the waters tomorrow night. In the wake of the front, strong winds of 25 to 30 knots with higher gusts and very rough seas of 6 to 10 feet will develop on Sunday and continue into Monday morning before easing. After a brief period of calmer conditions Monday afternoon into Monday night, another low pressure system developing in the central Gulf will begin to produce higher winds and seas over the waters on Tuesday. Increasing easterly flow of 15 to 20 knots will combine with a long fetch and increasing swell train to push seas up to nearly 10 feet by Thursday over the outer waters.
