Marine Weather and Tides
8/26/2020 The 7 day forecast is taking about 5 seconds to load but it will eventually load. NOAA is still working on it.
8/18/2020 NOAA continues to have trouble. Wind guest will occasionally be left off graphs. I am working with NOAA to resolve the issue.
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.

DISCUSSION. Tonight and Friday: Continued warmer than normal through the period but with greater rain chances Friday. Mid afternoon visible satellite imagery shows a better developed cu field than we have seen the last several days. Regional radars are showing a few light returns just north of Interstate 10 over southeast Louisiana tracking to the northwest. Our airmass was trying to moisten ahead of a cold front that will be approaching our northwest most zones by this time Friday. Water vapor imagery/RAP analysis showed a shortwave trough over the Southern Plains that will result in more southwesterly flow aloft tonight and Friday while our flow aloft continued out of the south this afternoon. Surface analysis still had a ridge nosing across our CWA from the northeast. Together these features will continue to help increase moisture back into our CWA. There remains a low chance that some of the convection developing to our south will spread across our southern zones late this afternoon and early evening but the greatest chance for rain that we have seen in several days is expected Friday. Come Friday a northern stream shortwave and associated surface low will be moving well to the northeast of our region leaving a trailing cold front to slowly approach our CWA. Models remain in decent agreement that the cold front will take until Friday evening to move into our northwest most zones. Clouds and the chance for rain will increase over our CWA ahead of the cold front. This should result in lower afternoon highs but temperatures are expected to top back out in the low to mid 80s again. Temperatures tonight will continue above normal as well with most sites bottoming out in the mid 60s. /22/
Friday night through Wednesday: A more progressive weather pattern than of late will bring a few weather systems across the CONUS through the middle of next week. A longwave trough over the western and central 2/3rds of the country will become more amplified as a ridge over the eastern Pacific edges toward the West Coast. As a series of shortwave troughs swing over the Northern Tier, a frontal boundary will oscillate through our region. A southward push of cooler air will reach our area with a cold front Friday night into Saturday, with a chance for showers and thunderstorms in the warm air ahead of the front on Friday. At this time, severe weather is not expected.
The latest suite of model guidance have come into slightly better agreement with a shortwave trough digging far south along the West Coast over the weekend and closing off as a low pressure system over the Four Corners region of the Desert Southwest. With southwest flow aloft ahead of this amplifying system, and expected cyclogenesis along the frontal boundary to its east, it is looking more likely for the cold front reaching our area on Monday/Monday night to stall out in the region. Coolest temperatures and best rain chances look to stay north of the cold front (and mostly northwest of our area) through Monday night. Then depending on exactly how the trough to our west evolves, we could set up for more intense thunderstorm and heavy rain potential Tuesday and Wednesday.
Although guidance has been bouncing around, enough confidence in the western trough closing off into a low pressure system over the Southern Plains exists to edge temperatures warmer for Tuesday and Wednesday ahead of the frontal boundary. Thunderstorms on Tuesday will be in a drier environment and should be more isolated, but moisture will really be increasing across the region as we head into Wednesday. A fetch of mid and upper level moisture sets up from the Baja Peninsula region off of Mexico, while a surge of very moist air should be arriving from the western Gulf of Mexico. Longer residence times for moisture wrapping back around into the low could drive a flash flooding threat somewhere around the northern and northwestern portions of Mississippi, Louisiana, and Arkansas Wednesday into Wednesday night. These trends will be monitored over the next several days. /NF/27/
AVIATION. 18Z TAF discussion: The MVFR cigs over the se wl scatter in the next hour or two and VFR conditions are expected to prevail areawide until 09Z. After 09Z IFR/LIFR cigs wl be psbl in the se again with VFR conditions continuing to prevail elsewhere. The IFR/LIFR cigs in the se should improve by 16Z with VFR conditions expected areawide through 18Z. /22/

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.
