Synopsis for the middle texas coastal waters.. A weak to moderate easterly flow is expected to continue tonight through Tuesday. Deep moisture over the coastal waters and a weak upper level disturbance will contribute to scattered to numerous showers or Thunderstorms through Tuesday night. Scattered showers and Thunderstorms will remain in the forecast from Tuesday night through Thursday as deep moisture will remain over the region and a weak upper level disturbance will persist along the coast. Onshore flow will increase to moderate to occasionally strong Thursday into Friday as an area of low pressure develops over west texas. Rain chances will decrease by Friday as drier air slowly works back into the region.

Short term (tonight through Tuesday night)
Scattered convection ongoing this afternoon, with coverage greater
far inland along the convergence zone. Isolated activity moving
west across the coastal waters, with isolated development along
the coastal counties. Should see activity along the coastal region
to diminish shortly with the marine layer moving in. There is a
mid-level shortwave low currently digging through northwest texas
with convection firing up. Models take this shortwave and move it
farther south this evening. Convergence is expected to increase
late tonight through Tuesday with the shortwave from the north
and surface coastal trough along the southern texas coast to the
south. Combined with pwats over near or over 2 inches, expecting
another day of showers and thunderstorms with scattered to even
widespread coverage. Storm motion again remains rather weak so
slow moving storms again are expected. And with the deep tropical
moisture, locally heavy rain and flooding will be possible. No
capping and instability values ranging from 1500-2500 may allow
for a few strong storms with gusty winds possible hinted by the
inverted-v profiles. With the southern push from the shortwave,
moisture is slowly forced farther south, which should aide in
trending pops down through Tuesday night, but maintain chance
pops across the waters and across the coastal counties.

Daytime temperatures again should generally range in the lower
90s across much of the region, with the exception along the coast
where temps in the mid to upper 80s will be possible due to the
expected increase in rain and cloud coverage. Overnight lows to
generally range in the mid 70s.

Long term (Wednesday through Sunday)
Not too much of a change from the previous handful of forecast
packages. Still have the copious tropical moisture hanging around
through at least the end of the work week. Mostly diurnally driven
convection will persist through end of the work week as it taps
into this moisture with sea breeze and outflow boundary
interactions.

Poor mans surface pressure ensemble shows a tightening pressure
gradient in response to a deepening low over west texas Thursday
into Friday. This will help to scatter out the convection a bit
more than we have seen recently so effectively we continue to
carry lower pops Thursday into Friday. Given we are still in full
on tropical airmass mode, the showers and thunderstorms will be
able to produce heavy and efficient rainfall. Temperatures climb
to slightly above seasonal averages with just a tad less cloud
cover and slightly drier air moving into the region around Friday.

This will be enough to boost heat index values back towards the
105 to 109 degree mark. Drier and warmer conditions still expected
for the upcoming weekend.

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.
