Short term (tonight through Monday night)
The upper ridge over the area will move to the northwest through
the period as the tutt low over the eastern gulf of mexico moves
to the west. The tutt low is expected to be just east of the
coastal waters by 12z Tuesday. GOES 16 image of precipitable water
shows an axis of higher moisture with pwat values around 2 inches
over the western gulf of mexico to the west of the tutt low. This
area of moisture is expected to reach the coastal waters late
tonight and into the coastal plains on Monday. Isolated to
scattered convection should form by mid morning and move inland
through the afternoon with the sea breeze boundary. Will only go
with pops of 20-30 percent. The high temperatures will be slightly
lower on Monday with increased cloud cover. Isolated convection
will redevelop over the coastal waters late Monday night.

Long term (Tuesday through Sunday)
Weakening tutt low will back into the area from the east on Tuesday
before dissipating mid-week. Enough moisture (around 2 inches
pwat) and a slightly favorable thermodynamic profile for
convection... Especially Tuesday. Will maintain current 20 pops
west 30 east Tuesday then cut back to area wide 20s for Wednesday
and Thursday. Combination of slightly lower heights and a little
more cloud will allow high temps to cool a degree or so each day.

Generally undercut the mex numbers by 1-2 degrees.

The forecast for the end of the week into the weekend remains highly
dependent on what happens with harvey's remnants. At a minimum it
looks like moisture will increase Fri Sat with the deterministic gfs
progging pwat around 2.25 inch for much of the area. Will hold pops
in the chance range for now with the highest chances(40%) on
Saturday. Should a stronger low end up tracking further north into
mexico higher pops would be warranted, while a weaker further south
wave might have little impact. Plenty of time to monitor... Stay
tuned.

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.
