Marine Weather and Tides
Version 3.4 |
12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed. 10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. |

Synopsis..A low pressure system will continue to push through the region tonight. High pressure will build in tomorrow and remain in place through Saturday. Another low pressure will then impact the waters Sunday into Sunday night. High pressure will follow this low on Monday, but another low pressure system should affect the region Tuesday into Tuesday night.

Area Forecast Discussion National Weather Service New Orleans LA 405 PM CST Thu Jan 23 2020
SHORT TERM. A dry slot and strong negative vorticity advection have taken hold of the forecast area this afternoon and this trend will continue into the evening hours. This has allowed for cloud cover to scatter out over the southwest portion of the CWA and temperatures have spiked into the upper 60s in this area. The remainder of the forecast area will see continued mostly cloudy conditions into the evening hours.
Heading into the overnight hours, lingering low level moisture combined with a weak elevated inversion should keep skies mostly cloudy through daybreak tomorrow. This inversion is being driven by weak cold air advection in the wake of the departing low pressure system. Temperatures should dip into the 40s due to this weak cold air advection.
A largely zonal flow pattern will then set up across the Gulf South tomorrow and remain in place through Saturday night. A fairly strong surface high will dominate the region tomorrow into the first half of Saturday. A dry and stable airmass can be expected, and skies will remain clear through this period. Temperatures should be near average both Friday and Saturday with highs climbing into the lower 60s and lows in the upper 30s and lower 40s.
Conditions will rapidly deteriorate Saturday afternoon into Saturday night as a fast moving shortwave feature begins to push into the region. Although this upper level system is on the weaker side, a decent Gulf low is expected to develop in a region of enhanced baroclincity across the western Gulf of Mexico. Pacific based moisture will stream across Mexico and Texas and begin to bring increasing cloud cover to the region Saturday afternoon and evening. Moisture should gradually build down through the evening hours, and expect to see scattered light rain showers in place by daybreak on Sunday.
LONG TERM. A progressive weather pattern will persist through the end of next week with a series of southern stream shortwave troughs pushing through the Gulf South. The initial system that will bring rain to the area by early Sunday morning will continue to pass through during the day on Sunday and have likely to categorical POP values in place through the day. The rainfall and cloud cover should suppress temperatures and have highs in the middle 50s across the area. Rainfall should gradually come to an end Sunday night as the trough axis pushes to the east and an increasingly subsident airmass builds in from the west.
A shortwave ridge axis will then build into the area on Monday and remain place through early Tuesday. Weak surface ridging will also build in on Monday and remain in place through Monday night. Temperatures will be largely near average with highs in the low to middle 60s and lows in the 40s. Skies may not completely clear due to some lingering low level moisture, but a dry forecast is in place for Monday and Monday night.
The next upper level trough and associated surface low will pass over the area Tuesday afternoon into Wednesday. Models are good agreement that the surface low associated with this trough will sweep directly over the forecast area. As a result, the risk of thunderstorms remain low with this system. Expect to see scattered showers develop by Tuesday afternoon and linger into Tuesday night as the surface low pulls through the area. A dry slot should punch into the area on the back side of the passing trough axis on Wednesday, and this will lead to clearing skies and decreasing rain chances through the day. Weak ridging should build in Wednesday night and expect to see a period of mostly clear skies into Thursday morning.
AVIATION. A mix of MVFR and IFR ceilings are expected to redevelop tonight and linger through 12-14z tomorrow. Strong boundary layer mixing will lead to rapidly clearing skies and VFR conditions after 14z.
MARINE. Weak cold air advection tonight into tomorrow will result in a period of northwest winds of 15 to 20 knots and seas of 3 to 6 feet. High pressure will settle over the area by Saturday and winds will turn lighter and more variable. Another developing low pressure system in the Gulf will bring a period of stronger easterly flow to the region Sunday into Sunday night. Expect to see winds of 15 to 20 knots and seas of 3 to 6 feet return. High pressure will then settle back in on Monday with lighter winds and calmer seas expected through Tuesday.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
