Update
Mostly clear this evening with warmer temperatures being observed
across the area in comparison to last night. This is a result of
easterly flow pushing higher dewpoint temperatures inland. The
only feature of note is a subtle backdoor front pushing through
the area from north to south. Behind the front, surface dewpoint
temperatures increased 15 to 20 degrees from the mid 20s and lower
30s into the upper 40s and lower 50s. With the increased
moisture, much warmer temperatures will be observed overnight with
patchy fog possible across the i-10 corridor for Sunday morning.

Nighttime microphysics imagery courtesy of goes-16 reveals a broad
shield of upper level cirrus advancing across the gulf coast. This
shield of clouds provided by a weak trough propagating across the
gom, will provide some limitation to the radiational cooling
through the overnight. High pressure remains dominate into Sunday
with another phenomenal day featuring mostly sunny skies and
temperatures near or slightly above normal.

Aviation
PrevailingVFR conditions. Patchy fog possible a few hours before
sunrise with light easterly winds continuing on Sunday.

Marine
Weak cold front crossing the waters overnight as surface high
pressure remains north of the area. Light winds and low seas are
expected into early next week.

Rip currents:moderate risk of rip currents continues into Sunday
with onshore flow and long-period swell.

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.
