Short term[this afternoon through Thursday]
Showers and isolated thunderstorms are currently developing mainly
south of i-10 and east of i-45, and are expected to gradually move
north to northeast as the afternoon progresses. This activity is
expected to dissipate by the evening with the loss of heating. For
tonight, expect clear to partly cloudy skies with low temperatures
ranging in the mid 70s to low 80s. Passing showers are possible over
the gulf waters late tonight to early Thursday morning, and could
move into the coastline from time to time.

Thursday, light southerly wind flow and high temperatures ranging in
the low to upper 90s expected. Mid to upper level ridge will start
to retreat to the west, decreasing subsidence across southeast
texas, as an upper level trough moves across the great lakes region.

Deep low level moisture is expected to begin to move into the
region, but should remain mainly along the gulf waters and southern
counties throughout the day. Data shows pwat values between 2.00 to
2.25 inches lingering across the aforementioned areas starting
Thursday morning through Thursday evening. Elsewhere, pwat values of
1.40 to 1.90 inches expected. With the ridge further west and low
level moisture gradually increasing across the gulf and southern
regions, expect showers over the gulf waters and coastal regions in
the morning, followed by showers and thunderstorms developing across
the southern and central regions during the late morning and
afternoon hours. Most of the activity is expected to dissipate in
the evening. However, showers and thunderstorms are expected to
continue over the local waters... Occansionally moving into the
coastal areas throughout the night. Low temperatures will remain
in the mid 70s to low 80s. 24

Long term [Friday through Tuesday]
Chances of shower and thunderstorms activity will increase
Friday. Mid to upper level trough will slowly move across the
great lakes region and the ridge will remain west of texas Friday.

Deep low level moisture will continue to filter into the gulf
water and southern regions of southeast texas, moving further
north as the day progresses. Pwat values between 1.70 and 2.30
inches should encompass the region by Friday afternoon,
particularly along the southern and central regions. Pwat values
of 2.20 to 2.50 inches is expected to remain mainly over the gulf
waters. Expect shower and thunderstorm activity to continue over
the gulf waters and southern portions of southeast texas early
Friday morning. As the day progresses, shower and thunderstorm
coverage and intensity will increase and expand further inland.

Strong storms will be capable of producing periods of heavy
rainfall, frequent lightning and gusty winds. The heavy rainfall
could lead to ponding of water along roadways and areas of poor
drainage as well as reduced visibility.

For the upcoming weekend, a similar pattern looks to set up with
the deep low level moisture lingering over the gulf waters as well
as the southern and central regions. Additionally, an upper level
disturbance or shortwave will move eastward across central conus
and north of texas Saturday, elongating southward into the eastern
tx and la region Sunday. On Monday and Tuesday, low level
moisture is expected to decrease, however, the proximity of the
upper level trough could continue to enhance shower and
thunderstorm activity across southeast texas, mainly in the
afternoons. Expect periods of showers and thunderstorms along the
gulf waters and southern and central regions throughout the day,
with lighter activity developing over the northern regions. At
nighttime, activity is expected to dissipate inland and persist
mainly over the waters and coastal regions. High temperatures will
range in the mid to upper 90s north of i-10 and in the low to mid
90s south of i-10 each day. Low temperatures will range in the
mid 70s to low 80s. A southerly wind flow is expected to prevail
throughout the forecast period. 24

Marine
Expect more of the same over the next couple of days with light to
moderate onshore flow during the day, then slightly increasing
onshore flow during the overnight hours. Winds and seas slightly
increase over the weekend flirting with scec criteria. This is due
to a surge of tropical moisture from the NW caribbean entering the
northern gulf. No tropical development is expected from this system.

Onshore flow continues for the start of next week as an upper level
ridge remains over texas.

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.
