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.

UPDATE. Updated for 00Z aviation discussion
AVIATION. 00Z TAF discussion: VFR conditions will continue through the evening. MVFR ceilings will likely affect KGLH/KGWO by morning as clouds move in and some light rain as well. The remainder of the sites should remain VFR through much of the period. /28/
DISCUSSION. Tonight and Tuesday . High pressure at the surface will continue to slide east across the northern Gulf of Mexico through Tuesday. This, while flow aloft gradually flattens and becomes more zonal across the region. A cold front will sag south and into northern portions of the CWA on Tuesday, before eventually stalling. This will bring an increase in clouds across the CWA during the overnight hours and into Tuesday. Although our airmass is quite dry at the moment, we will be subtly moistening ahead of the front. This, in addition to weak forcing along the front, will bring increased rain chances across locales mainly along and north of the Interstate 20 corridor on Tuesday.
As far as temperatures are concerned, with the aforementioned increasing clouds and moisture, lows tonight will be a little warmer as they range from the mid 30s to mid 40s. Then on Tuesday, because of the cold front stalling over the area, a sharp temperature gradient will exist. Highs north of the front will generally be in the 50s under mostly cloudy skies. Meanwhile south of the front, highs will be in the 60s to around 70 under partly cloudy skies. /19/
Tuesday night and Wednesday: Light rain showers will continue into Tues night along and behind a quasi-stationary front. However, they will begin to diminish in coverage as a mid level shortwave departs and surface high pressure over the NE Gulf builds back into the area as shortwave mid/upper ridging temporarily builds just to our west. The front will weaken somewhat and slip a bit farther south, and though isolated showers may linger into Wednesday morning, much of the day is looking dry for now.
Wednesday night through Friday: The break in the rain will be short- lived as the surface front wavers back northward, the surface high slides east and southerly low level flow resumes. With upper flow mostly zonal, however, the front is likely to begin to stall and linger over the region until a cutoff mid/upper low ejects eastward and shoves it southward again through the area on Friday. In the mean time, periods of showers are likely along the front throughout this entire period. And there is potential for a couple periods within this time frame of somewhat enhanced rainfall as waves associated with upper divergence increases in the right entrance region of an upper jet streak move along the front. Right now WPC/model consensus is a swath of 2-4" rainfall accums across the area during this time. Given forecast PW/IVT in the >90th percentile Thursday through Friday, flooding is a concern that will need to be monitored, particularly if it becomes more apparent that convection/higher rain rates are more likely. For now, scattered thunder was added to the forecast for Thursday night given forecasted weak elevated instability. Confidence is not yet high enough to warrant mention of a flood threat in HWO/graphics, but this is something we'll continue to monitor through the week.
Saturday through next Monday: Another brief break in the rain is anticipated for most of the area late Friday into Saturday, but the pattern will remain active and progressive as another upper trough dips across the southwestern CONUS over the weekend. Southerly low level flow will return Sunday into Monday, and with this system, guidance is pointing toward a more organized surface cyclone tracking from the Southern Plains into the Ohio Valley and associated cold front moving through our area next Monday or Tuesday. If sufficient instability materializes with this system, severe weather could be a concern given ample shear anticipated and climatologically favorable surface low track and upper height fields. However, confidence is low at this stage with it still 7-8 days out, so this is yet another item to keep on our radar as we head through the upcoming week. /DL/

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
