Marine Weather and Tides
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

area forecast discussion... Updated
national weather service new orleans la
1053 am cdt Mon jun 18 2018
In light of advancing tropical squall bands into the
coastal areas and penetrating through the atchafalaya basin,
updated hourly and MAX temps for today to reflect rain cooling in
places that may have seen their MAX this morning. Locations
generally east of the convection should still be on track to reach
the upper 80s before being affected by rain this afternoon. Also
aligned pops to show 60-70% in areas where squall bands area
passing through, but lowered to 20% or so in jackson co, ms where
somewhat drier easterly flow is nosing in.
Pretty moist sounding with precipitable water at 1.93" and lifted
index -10 on surface based and most unstable lift processes. This
is essentally auto-convective and being realized with efficient
rainfall in these squall arcs that move northward off the gulf.
Chap output on 357k lift shows 60% pop with gust potential 24kt 28
mph, though several locations have reported a bit higher, closer
to 40 mph. Chap rainfall 3.97" with storm track potential 6.22".
This may be difficult to come by due to storm motions around 30
mph, but monitoring for any training aspects in bands moving off
the coastal waters. Wind profile shows SE 15-25 kt surface to
about 13kft, e-ne 10 kt layer to 20kft, then SW 20-50kt to 46kft.

latest surface analysis showed a broad 1019mb high over alabama
and georgia and a deep 1006mb low over eastern colorado. Both
features were yielding a southerly flow over the southern plains
and lower mississippi valley. Surface dewpoint values were
generally in the lower 70s over the southern plains, mid and lower
Upper air analysis showed a broad ridge of high pressure over the
eastern half of CONUS with an inverted trough axis along the texas
coast. In addition, a deep low was located over the great basin.
Precipitable water values of 2.1 to 2.3 inches were along the
texas coast, 1.9 to 2.1 inches over louisiana, and 1.6 to to 1.8
inches over mississippi and alabama. 18
the inverted trough axis will continue to push northwest into
central texas. Relatively dry air, precipitable water values
between 1.7 to 1.9 inches are expected over the forecast area
through today. Rain chances will decrease to normal for this time
year. Surface heating and moisture will yield scattered coverage
Upper level high will drift back southeast from tennessee valley
to florida later today and slowly settling over northeast gulf
and florida Tuesday through Thursday. A deep upper low over great
basin will track east to the northern and central plains. This
feature will pull moisture just northwest of the forecast area
Wednesday and Thursday and rain chances will maintain rain chances
near norm for this time of year.
Upper level low will continue track east with the associated
moisture axis pushing east over the over the north half of the
forecast area late Thursday and Friday. Although slightly
increased moisture will be in play, dynamics will remain north of
the area thus maintaining rain chances near normal Thursday. The
upper level low will continue to track east to the great lakes
over the weekend. The lifting of the weak trough axis north of the
lower mississippi valley. This will allow heights to rise and
create a slight general descent of air over the area over the|
weekend. As a result, will lower rain chances to 20 and 30
percents in afternoon over the weekend. Temperatures will remain
normal to slightly above through the forecast period. 18
a tropical wave in the northwestern gulf of mexico has been a
generator for hazardous coastal water conditions. Latest
observations at buoy 42040 show that winds have fallen to around 10
knots and seas down to 4 feet. Points west of the mississippi river
still have winds over 20 knots. Thinking is that the pressure
gradient will gradually relax enough later this morning for winds
and seas to fall below SCA criteria. So have extended the advisory
to 16z, but cut off the zones east of the river. Winds and seas
should continue to back off heading into the rest of the week as a
surface ridge of high pressure settles in over the northeastern
gulf. Southeasterly flow will persist with quite light winds in
waters south of ms and closer to 10 knots in waters west of the
vfr conditions are expected to dominate the period outside of
showers and thunderstorms. Highest chances of shra tsra are west of
khdc to knew line. Will use tempo or prob30 for tsra which may be
accompanied by briefly lower vsby and CIGS bordering MVFR category.
Any lower ifr conditions are expected to be too brief and localized
for inclusion in the tafs.

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
