Marine Weather and Tides
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.

UPDATE. Updated for 12Z aviation discussion
AVIATION. 12Z TAF discussion: VFR through at least the next 6 hrs in most locations. Some light sprinkles out there, but mostly a cirrus sky. Light and variable winds under the ridge, becoming increasingly easterly through the day. Precip chances increasing through the afternoon and into the evening, but will be scattered in coverage early. Next main concern for avn is the development of showers/possible thunderstorms tomorrow night.
Today and tonight . A narrow high pressure ridge remains in place for the the lower Mississippi Valley and Central Gulf Coast today. Weak high pressure not enough to keep a few showers from popping up over the northern tier of the state this morning. Little more than sprinkles are expected in most locations. Winds are generally very light under the ridge, and mid and upper level moisture streaming clouds across the region ahead of a developing storm system to the west. Cloudy conditions will keep the daytime highs mainly in the 70s . with lower 80s closer to the coast.
Forecast gets more complicated moving into the overnight hours. A shortwave aloft moves out of the Southern Plains this afternoon/evening, with its associated developing surface low. Models have developed some showers and thunderstorms out across the state later this afternoon ahead of the low. Storms will be well north of the front stalled off the coast, and not have access to much in the way of surface based instability. Continued easterly flow because of the surface ridging in the eastern Gulf also assists in delaying any theta-e advection ahead of the low. The larger concern develops later in the evening as the frontal boundary/richer BL moisture finally surges northward. Models delay this until closer to 06z . bringing a narrow window of severe storm development to the overnight hours tonight/early Tuesday. Thunderstorm development north of the boundary will be a concern for wind and hail, elevated and tapping into cooler air. Once the developing front starts to lift through the region, shear is also increasing within the warm sector, adding a vertical assist to any ongoing convection. This severe threat is contingent on many moving parts, but the model runs are starting to show a little more continuity from run to run. Will be mid morning Tuesday until the storms clear out of the forecast area.
Tuesday morning through the weekend .
Storms associated with an upper level disturbance sweeping through the Mid Mississippi River Valley will be ongoing as we start our day on Tuesday. The severe weather threat will have shifted to areas east of the I-55 corridor. Ample deep layer shear will exist throughout the region with the best instability values being relegated to areas south the I-20 corridor. The decision was made to extend the slight risk further east to highlight the continuing threat Tuesday morning and to match better with our neighbors who have been outlooked in the Day 2 period. The main threat with storms on Tuesday morning will be damaging straight line winds, hail, and tornadoes.
The surface front will be east of the region by Tuesday afternoon with the severe threat waning before midday. A cooler airmass will begin to filter into the region Tuesday evening and lows on Wednesday morning will fall into the 40s areawide as a surface high becomes centered over the region. Dry weather will continue through the rest of the workweek as an upper ridge builds overhead. Temperatures will be back above normal by Thursday as the high shifts east of the region with the ridge still overhead. Although model guidance begins to fall out of consensus as the weekend approaches, most guidance increases rain chances over the region during the weekend as another surface front approaches the region from the west.

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. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
