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.

Area Forecast Discussion National Weather Service Shreveport LA 1235 PM CDT Tue Mar 31 2020
Most sites are starting out this TAF period in MVFR due to low ceilings, however as the north wind keeps kicking, dry air will continue to filter into the Four-States Region. By 01/00z, all sites should be in VFR with scattered skies due to the aforementioned dry air. Look for continued clearing into cirrus above 25,000 feet, and eventually SKC for the remainder of this forecast period. /44/
PREV DISCUSSION. /issued 954 AM CDT Tue Mar 31 2020/
Morning observations were a few degrees warmer than the forecasted trend, and clouds are starting to mix out across the region. As such, quick morning update to bump up afternoon high temperatures a few degrees. /44/
PREV DISCUSSION . /issued 633 AM CDT Tue Mar 31 2020/
AVIATION . In the wake of the frontal passage, IFR ceilings will prevail with some brief periods of LIFR possible. As the upper level trough continues to progress eastward, these ceilings will improve to MVFR status during the morning into early afternoon hours. VFR conditions are expected to return to all sites by the late afternoon and will persist through the remainder of the forecast period. /35/
PREV DISCUSSION . /issued 336 AM CDT Tue Mar 31 2020/
SHORT TERM . /Today through Wednesday/
The cold front is shifting east across our eastern zones this morning and is ending precipitation from west to east as it does so. There may be some wrap-around rain early today across Southwest Arkansas as the parent upper level system shifts east but not expecting much. Winds are shifting to the north and northwest behind the front and could be a little gusty today but should remain below Lake Wind Advisory criteria. Short range guidance is wanting to hold onto the cloud cover into the afternoon, and if this happens, high temperatures today may not warm up that much. Have lowered them a tad but maybe not enough. Skies will clear and winds will decouple tonight as high pressure builds in at the surface; there may be some patchy fog around the region as a result. High temperatures will warm back into the 70s on Wednesday as upper level ridging builds in from the west. /35/
LONG TERM . /Wednesday Night through Monday Night/
The axis of an upper level ridge will move east of the area during the day Thursday allowing the flow aloft to transition back to southwesterly and brining more Pacific moisture back into the region. Another strong upper trough will move towards the Northern Plains. A surface low and dryline will sharpen over the Southern High Plains. Meanwhile, a cold front will dive southward towards across the Central CONUS.
A weak shortwave trough will move across the Southern Plains late Thursday, which should provide enough ascent in the warm air advection regime for scattered showers and a couple of thunderstorms across Central Oklahoma southward into Texas. This activity will move eastward into our area Thursday night/early Friday morning. There may be a brief break in the showers after sunrise Friday. The best large scale forcing will be far north of the forecast area, but strong instability combined with a weak upper disturbance embedded in the flow should result in widespread convection along and ahead of the cold front Friday afternoon through Saturday morning. Deep layer shear should also be strong enough to support the potential for at least a couple of severe storms Friday afternoon and evening. Damaging winds and large hail will be the primary threats.
Model guidance is in sharp disagreement regarding the potential for post-frontal rain on Saturday. Both models bring the front completely through the forecast area, but the GFS suggests dry air will move into the area during the day Saturday, so it is far less aggressive with QPF. On the other hand, the ECMWF maintains quite a bit of post-frontal rain across the entire area until late Saturday evening. Higher PoPs were kept across the southeast half of the area during the day Saturday, but were tapered down to chance PoPs in the northwest.
The medium range models agree that there should be a brief break in the rain Saturday night. However, yet another strong upper trough will be digging into the Great Basin on Sunday. Strengthening southwesterly flow will provide an ample supply of Pacific moisture for another series of shortwave troughs to tap into. More showers and thunderstorms are likely by Sunday afternoon and continuing for most of Monday.

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.
