313 am cst Fri jan 19 2018
.Short term (now through Saturday): widespread light rain and
drizzle with embedded isolated showers is affecting the central and
eastern portions of the bro cwfa and adjacent coastal waters.

Surface low pressure will develop along the lower texas coast today
and quickly eject off towards the northeast as closed 500 mb low
pressure progressively moves east across texas and into the
mississippi river valley. Rain chances will gradually taper off from
west to east today, and end altogether tonight, as the surface low
moves away. Dry weather with plenty of sunshine will then prevail
for Saturday as building mid-level high pressure replaces the closed
500 mb low. Below normal temperatures today courtesy of overcast
skies and ample rain chances will return to near normal values on
Saturday due to limited cloud cover and prolific sunshine.

.Long term (Saturday night through Thursday): temperatures continue
to recover Saturday night and Sunday with 500mb ridging overhead and
southeast flow continues at the surface. Above normal temperatures
will prevail through the rest of the weekend. Saturday night will be
mild with low temperatures Saturday night mainly in the 60s. Sunday
will be breezy, especially near the coast, as the pressure gradient
strengthens. High temperatures Sunday will be generally be in the
upper 70s to around 80 degrees with a mix of Sun and clouds. Mid
level ridging will move to the east late in the weekend as a cold
front approaches deep south texas.

The next cold front (from a milder source region) arrives Sunday
night bringing slightly cooler and drier air behind it. Some
showers will be possible with the front Sunday night into Monday
morning. Rain chances increase Tuesday night into Wednesday night
as a surface trough moves north and interacts with an upper level
disturbance. Rain chances diminish Thursday and Friday as the next
mid level short wave moves east and surface high pressure builds
into the region. Near normal temperatures are expected through
late next week.

.Marine: (now through Saturday): buoy 42019 reported east winds
around 14 knots gusting to around 18 knots with seas slightly under
4 feet with a period of 6 seconds at 02 cst 08 utc. Low pressure
will develop along the lower texas coast and move quickly off to the
northeast, allowing high pressure to resume over the western gulf of
mexico tonight and Saturday. The pressure gradient will be enough to
produce moderate winds and seas, with small craft exercise caution
for a portion of the lower texas coastal waters through the period.

Saturday night through Tuesday night: moderate southeast to south
winds will prevail along the lower texas coast Saturday night into
Sunday as the gradient strengthens ahead of the next cold front.

Marine conditions will briefly improve by Sunday evening as the
gradient relaxes ahead of the approaching cold front. The cold front
will move through the lower texas coastal waters late Sunday
bringing moderate north winds and moderate to high seas Monday and
Monday night. Marine conditions will improve Tuesday and Tuesday
night as high pressure spreads across the area. Periods of small
craft should exercise conditons to low end small craft advisory
conditions likely Saturday night through Monday night.

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.
