Synopsis for the middle texas coastal waters.. A cold front is pushing through the middle texas coastal waters this morning. Very strong offshore flow is developing behind the front with gale force wind gusts expected in open waters through this morning. Showers will also persist through the morning. Winds and seas will gradually subside this afternoon and evening, however small craft advisories will be necessary once the gale warning expires into the evening. Cooler and drier conditions are expected for Thursday.

Short term (today through Thursday)
Cold front had pushed through all of south texas and is currently
in the offshore marine zones. As expected, strong winds have
developed in the wake of the front. While the strongest winds
lasted only a brief time with the frontal passage, coastal
locations will expect the very strong winds to persist through the
morning. Have gone ahead and issued a wind advisory through noon
for islands and eastern portions of coastal counties. Expect
sustained winds around 30 mph with gusts around 40 mph in these
locations. For the remainder of the coastal bend and coastal
plains, wind gusts around 30 to 35 mph will continue this morning.

Showers are still pushing through the coastal plains and coastal
bend. The back edge of the rain is currently across duval and live
oak counties. Timing this out, the main edge of the rain should be
near the coast by around 6am, but will keep a slight chance pop
for coastal counties with a bit of drizzle or light rain holding
back a bit farther. Everyone should be dry by mid-day. We'll be
much cooler today with highs mainly in the 50s.

High pressure builds into the region this afternoon and will
quickly decrease winds. By overnight, the ridge axis will drift
across south texas allowing for very light winds and cold
temperatures. Expect the area to largely stay above freezing,
especially as winds begin to turn onshore late in the night. It is
still not out of the question that a few low lying northern areas
could briefly hit freezing late in the night.

Thursday looks rather pleasant with mainly light onshore flow,
sunny skies, and temperatures in the 60s (low 60s east... Upper
60s west).

Long term (Thursday night through Tuesday)
Extended period begins between systems in our recent progressive
flow pattern. Winds turn northeast Thursday night before turning
onshore on Friday as strong high pressure builds in northeast of the
coastal bend. Models are increasingly settling on the ECMWF solution
swinging another impulse across the region Saturday and Saturday
night, with associated increases in rain chances. Upper support
exits by Sunday with a relatively weak frontal passage. Models show
synoptic flow becoming more meridional, with a stronger, although
dry, front moving through early next week. Arctic air behind this
stronger front will bring a bit of winter chill back to the area
toward the end of the period.

Marine
Gale force wind gusts can be expected this morning in the wake of
a strong cold front moving through the middle texas waters this
morning. Showers will also continue through late morning.

Conditions will gradually improve this afternoon, but small craft
advisory conditions will persist through the afternoon and into
the evening. A small craft advisory will need to be issued behind
the gale warning this afternoon. Generally quiet weather is
expected for Thursday. An upper level storm system will bring
scattered showers to the nearshore waters Saturday and Saturday
night. Offshore flow behind this system may briefly reach advisory
criteria late Saturday night or early Sunday morning. Flow then
quickly becomes onshore Sunday into Monday out ahead of a stronger
front. That front, currently forecast to pass through Monday
night, will bring strong to very strong offshore flow in its wake,
with advisory winds and seas with at least gusts to gale force on
Tuesday.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
