422 pm cdt Fri jul 21 2017

Short term (tonight through Monday)
The central gulf coast region will be under the influence of a
broad mid upper level low that will be moving west across the
northeast and north central gulf of mexico tonight, and towards
the western gulf coast region over the weekend. Higher moisture
content returned today with precipitable water (pw) values up to
the 1.9 to 2.0 inch range, and these values are expected to
persist through the weekend with some higher values between 2.0
and 2.25 inches south of lake pontchartrain on Saturday and across
the forecast area Sunday. This will support the forecast of good
scattered coverage of showers and thunderstorms Saturday with a
bit higher coverage expected on Sunday. Locally heavy rainfall and
some stronger thunderstorms with gusty winds and frequent
lightning will be possible. Temperatures are expected to trend
near to slightly below the seasonal averages.

High pressure is then expected to rebuild across the gulf of
mexico on Monday which should lower the rain chances substantially
and allow the temperatures to spike back to very warm levels.

Long term (Monday night through Friday night)
A general area of deep layer high pressure is expected to prevail
across the gulf, however the models indicate a series of
shortwaves moving southeast from the northern plains into the
northeast states. This may break off a lower latitude shortwave
trough weakness over the southeast states Tuesday that should be
progressive and move east towards the south atlantic coast by late
Wednesday, allowing deep layer high pressure to rebuild quickly.

This pattern will be generally be mostly dry (mainly isolated
convection at best) and very warm with above normal temperatures.

22 td

Aviation
Isolated to scattered showers and thunderstorms continue to
occasionally impact some of the terminals, but should start to
decrease in number going towards evening. Nocturnal convection
will be a possibility especially south of lake pontchartrain later
on in the night. Otherwise expectVFR conditions with afternoon
convection once again for Saturday. 13 mh

Marine
High pressure over the gulf of mexico is expected to result in
mostly south to west winds around 10 knots or less through the
weekend, then an occasional tightening of the pressure gradient
may cause winds to rise into the 10 to 15 knots range at times
over portions of the area early next week. 22 td

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.
