.Short term (now through Sunday): the 500 mb ridging currently over
the central and northeastern u.S. Will be eroded by a deep closed
moving in from the western states and a weaker closed low drifting
west over the southeastern states. As the 500 mb ridging gradually
breaks over the rgv... Day time heating will help drive isold sct
conv throughout the weekend. The 00z bro sounding indicates that
overall moisture and instability is a little limited with an mucape
of 1860 j kg and a pwat of 1.94 inches. The GFS mos pops are the
wettest versus the nam ECMWF numbers. Will lean towards the wetter
gfs pops as the rgv has seen pretty decent conv over the last couple
of days. The latest kbro radar imagery also indicates some conv over
the gulf waters trying to edge into the inland areas early this
morning.

Will go close to persistence for temps around the rgv as short term
guidance is in reasonable agreement for highs lows.

.Long term (Sunday night through Friday): deep south texas will
continue to be on the western side of a mid-level ridge over the
central gulf and a mid-level trough over the western conus. Surface
high pressure across the southeast united states extending into the
northern gulf of mexico will prevail Sunday night and Monday. A cold
front is expected to move into northern texas on Tuesday and
gradually move south through the week. Deep tropical moisture is
expected to pool ahead and along the frontal boundary. The latest
gfs ECMWF suggests the cold front will move into deep south texas by
late week. Precipitable water values near or above two inches will
support isolated to scattered showers and thunderstorms through most
of the period. Rain chances diminish by Friday night as drier air
filters into the region in the wake of the front. Temperatures will
to remain above normal through Thursday night due to abundant cloud
cover and high dewpoints. Near to slightly below normal temperatures
are expected Friday and Friday night in the wake of the front.

.Marine (now through Sunday): broad surface ridging sprawled over
the eastern states will maintain light to moderate winds and seas
across the lower tx coastline. Expect e-se winds across the region
with gulf seas ranging generally in the 2 to 3 foot range. A light
to moderate chop is expected on the laguna madre. No SCA conditions
expected through Sunday.

Sunday night through Wednesday night: surface high pressure
across the northeast gulf of mexico will maintain light to
moderate southeast flow and low to moderate seas across the lower
texas coastal waters through midweek. A cold front will approach
deep south texas and the adjacent coastal waters by late in the
week which will result in higher winds and seas. Small craft
exercise cautions conditions likely in the wake of the front.

Isolated to scattered showers and thunderstorms will also be
possible at times through the period.

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.
