Discussion Updated for latest aviation discussion below.

Aviation Satellite images and surface observations indicate low
clouds with moderate north winds across deep south texas early
this morning. Expect ifr to MVFR ceilings across the rio grande
valley through around mid morning before drier air filters into
the area with skies clearing from west to east. Ceilings are
expected to improve toVFR by late this morning. Low clouds will
return late this evening into the overnight hours with MVFR
ceilings possible after 06z.

Prev discussion issued 439 am cst Wed feb 20 2019
short term (now through Thursday): a weak cold front has moved off
the lower texas coast early this morning. Low clouds with light rain
and or drizzle with fog will continue near the coast through mid
morning. Drier air will filter into the area by this afternoon, with
skies clearing from west to east. High temperatures today will
generally be in the 60s as high pressure builds in from the
northwest. The front us expected to stall across the western gulf of
mexico later today and tonight. Rain chances start to increase again
late tonight into Thursday as the frontal boundary lifts back to the
north. Low temperatures tonight should range from the lower 50s
across the northern ranchlands to the mid to upper 50s across the
valley with increasing cloudiness. High temperatures Thursday should
reach to the low to mid 70s under a mix of Sun and clouds.

Long term (Thursday night through Tuesday): weak inverted surface
troughiness along the lower texas coast will produce isolated
patches of precipitation Thursday night. Dry weather will then
develop and prevail until late in the weekend, when the formation
of another inverted trough in the wake of the Saturday passage of
a front will generate scattered precipitation for the final 48
hours of the forecast period. Temperatures will ride a roller
coaster during the long term, with the warmest values occurring
in advance of the Saturday cold front, and more near normal values
afterwards.

Marine (now through Thursday): buoy 42020 reported north-
northwest winds around 21 knots gusting to around 27 knots with
seas slightly under 5.2 feet with a period of 8 seconds at 0310
cdt 0910 utc. High pressure building into the region early this
morning has allowed north winds to increase and seas to build. A
small craft advisory is now in effect for the lower texas gulf
waters until noon today. Small craft advisory conditions may
linger across the gulf waters into the afternoon. Small craft
should exercise caution on the laguna madre today. Winds will
become northeast to east and weaken tonight and Thursday as a
coastal trough develops again along the northeast mexican coast
into the lower texas coastal waters.

Thursday night through Tuesday: the most adverse marine conditions
during the period are expected to occur during the weekend due to
the approach and passage of a cold front. Small craft advisories
may be needed along the lower texas coast in association with the
frontal passage. Otherwise, generally moderate winds and seas are
anticipated for the remainder of the forecast period with surface
high pressure in control.

Bro watches warnings advisories
Tx... None.

Gm... Small craft advisory until noon cst today for gmz150-155-170-175.

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.
