Synopsis for the middle texas coastal waters.. A generally weak onshore flow is expected tonight. Onshore flow will increase to moderate levels on Thursday and continue into Thursday night as a surface low pressure system deepens over the southern plains. Chances for showers and Thunderstorms will continue through Thursday night as an upper level disturbance and sufficient moisture remains across the middle texas coastal waters. Rain chances will decrease through Friday as drier air slowly works back into the region. Moderate to occasionally strong onshore flow will continue through the weekend becoming weak to occasionally moderate early next week.

Discussion
Water vapor imagery is showing drier air moving into the region
(eventually), with upper trough axis just off the coast. However,
evening sounding still showed pwats just above 2 inches. With
smaller scale models keeping the rain out of the inland areas
until late (and very isolated), have decided to lower pops for the
evening and overnight, but still mentioning rainfall over inland
areas mainly over the NE areas where better chances for rainfall
reside. Other than that, rest of the forecast is fine and did not
make any changes to the remainder of the forecast.

Aviation...

except for possible and temporary MVFR CIGS and or vsbys at kali
and kvct, should seeVFR through the period. With winds forecast
to be shifting more to the south later tonight, that should
preclude any persistent lower clouds (still could have some
temporary conditions). Otherwise, think any showers during the
period will be confined to kcrp and kvct terminals with not enough
confidence to have tempo and or prob30 for these locations. Winds
start from the south after sunrise and go sse in the afternoon
with the sea-breeze. Overall, terminal forecasts are not too
different from climatology for terminals.

short term (tonight through Thursday night)...

isolated to scattered convection over the victoria crossroads and
northern coastal bend continues to slowly sink southwestward.

These showers and storms will persist through the early evening
before diminishing with the loss of daytime heating. However,
additional redevelopment is expected tonight mainly over the gulf
waters and immediate coastal locations. Low tonight will be in
the mid 70s inland to upper 70s to lower 80s along the coast.

Mid level weakness will remain over south texas on Thursday. The
weakness combined with pw values between 1.7 and 1.9 inches will
lead to isolated to scattered convection again tomorrow. Favored
locations will be over the gulf waters with only 20 pops over the
brush country. Similar to today, showers and storms should wane
with the loss of daytime heating a warming trend will begin tomorrow
with highs topping 100 over the western brush country and rio
grande plains. Heat index values will also be an issue and a heat
advisory may be needed across the southern coastal bend and
perhaps webb county.

Long term (Friday through Wednesday)...

much drier conditions develop heading into the weekend and into next
week. Mid level ridging begins to build in from the western gulf
drying the mid levels further and allowing mid level temperatures to
rise. H85 temperatures are expected to rise to 20c-23c. However, in
the lower levels, moisture remains with pwats ranging at times
between 1.5 to 1.7 inches. As a result, continue to keep silent 5-10
pops through next week. Although the increase subsidence should
hinder much in the way of convection, a rogue shower to thunderstorm
may be possible along the sea breeze during the afternoons, more so
into early next week.

Temperatures through the week will warm back into the low to mid 90s
across the coastal region and near the 100 degree mark across areas
generally west of highway 281. Heat index values will also be on the
rise through the period, with the highest values Friday. Heat index
values on Friday may range from 110-112 across portions of south
texas. A heat advisory may be required for Friday. Otherwise, heat
index values are expected to range from 105 to 109 through early
next week.

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.
