Synopsis for the middle texas coastal waters.. Areas of sea fog will be possible over the bays and near shore waters this evening into the early overnight hours. A cold front will move push through the coastal waters during the overnight hours. A moderate northeasterly flow is expected Tuesday morning and become weak to moderate easterly by late in the afternoon. Isolated showers will be possible with the front overnight also. The isolated showers will linger over the gulf waters south of port aransas early Tuesday morning. Drier air will move in behind the cold front for Tuesday afternoon and Tuesday night with a weak to moderate east flow expected Tuesday night. Onshore flow turns from easterly to southerly on Wednesday, as low pressure develops across the plains. This will increase moisture across south texas and gradually build seas into the weekend. A cold front passes on Saturday with showers and Thunderstorms possible into Sunday. Moderate northerly winds behind the front further agitate seas late Saturday into Sunday, with small craft advisory conditions possible.

Short term (tonight through Tuesday night)
The cold front was located from south of college station to near
san marcos and then into the northern hill country while the
pre-frontal trough was along an iah-cot line. Air mass ahead of
the boundary is moderately unstable. Latest SPC meso-analysis
shows MLCAPE slightly above 1500 j kg from the victoria crossroads
into the northern brush country. High resolution convection
allowing models are not showing much in the way of convective
coverage this evening. But low level convergence will increase
over the northern portion of the forecast area as the front
approaches this evening. Water vapor imagery also shows a weak
upper level jet streak moving southeast across south texas.

Confidence is not high there will be much convection this evening
but with the amount of instability in place, feel there should be
a mention of isolated thunderstorms for the northern brush country
to the victoria crossroads this evening. The front will steadily
push through the area overnight. Hi-res arw and texas tech wrf
show an increase in coverage of showers over the southern brush
country to the southern coastal bend overnight. Increased pops to
30 percent in these areas. Drier air will move into the area from
the northeast behind the front Tuesday morning. Will keep a slight
chance of showers in the forecast for early Tuesday morning
across the southern counties of south texas. Clouds will decrease
by the afternoon over the coastal plains while cloud cover will
persist over the brush country. Will see slightly warmer
temperatures for the victoria crossroads and northern coastal bend
where more sunshine is expected on Tuesday. Moderate northeast
winds in the morning will shift to easterly by the late afternoon.

Clouds will linger over the brush country Tuesday night while
skies will be mostly clear for the mid-coast. There is the
possibility of sea fog forming along the coast this evening before
the front and northeast winds lead to improvement for the islands
and near coastal regions.

Long term (Wednesday through Sunday)
Mid level ridge builds across texas on Wednesday, as surface low
pressure develops across the southern plains into Thursday, turning
easterly flow along the middle texas coast more southerly through
the end of the week. This allows moisture to increase late week,
likely resulting in more cloud cover, and gradually warming high
temperatures a couple of degrees each afternoon. Surface low in the
plains heads northeast, dragging a cold front through south texas
Saturday afternoon with breezy northerly winds behind it through
Sunday. Models differ slightly heading out of the weekend, so have
stuck with the trend of holding the frontal boundary and weak
coastal low pressure across the western gulf of mexico, keeping the
chance of rain persisting into Monday.

Marine
Surface dewpoints in the upper 60s to lower 70s moving across
the slightly cooler waters along the coast will lead to areas of
fog forming over the near shore waters this evening and move into
the bays. The cold front will reach the northern marine zones by
midnight with some improvement in visibility as northeast winds
steadily increase. The front will move through the offshore waters
by 12z Tuesday. Isolated showers will be possible tonight with the
front and linger across the southern marine zones into early
Tuesday morning. The northeast winds will increase to moderate
levels Tuesday morning (may even briefly approach SCA over the
offshore waters) and then become easterly by late afternoon. The
weak to moderate easterly flow will continue through Tuesday
night. Seas are expected to build to 5 feet mainly over the
offshore waters with the increased northeast winds Tuesday and
subside to 3-4 feet Tuesday night.

As low pressure begins to develop across the plains, southerly flow
returns across the waters of the middle texas coast through the end
of the week, with light to moderate seas of 2 to 4 feet building
gradually to 3 to 5 feet by Thursday night. Low pressure in the
plains heads northeast, dragging a cold front through south texas on
Saturday, with breezy northerly winds behind it, further agitating
seas. Small craft exercise caution to small craft advisory
conditions likely by late Saturday and continuing into late Sunday.

A few gale force wind gusts may be possible Sunday morning across
offshore gulf of mexico waters.

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.
