249 pm cdt Thu may 25 2017
.Short term (tonight through Friday night): 500mb ridge across
the central united states this afternoon will begin to move
eastward tonight into Friday as a 500mb subtropical ridge develops
across northeast mexico and the rio grande valley. This will
continue to provide subsidence across the CWA even as an onshore
flow continues to increase across the lower texas coast tonight
into Friday. Very warm... Breezy and humid conditions will prevail
across the rio grande valley and northern ranchlands tonight
through Fri night with no rain chances expected through the
period.

.Long term (Saturday through Thursday): hot and dry weather will
prevail Saturday with weak ridging over the southeast united states
and high pressure over the gulf. High temperatures locally will
range from the lower 90s to above the century mark. Heat index
values will increase to between 105 and 110 degrees Saturday
afternoon. A front will overtake the dry line upstream, provoking
convection over the big bend area of texas. By Sunday, with a mean
trough over the upper midwest and ridging again building over the
western united states, high pressure will spill southeast from the
upper northwest united states, pushing into central tex. A similarly
hot day relative to Saturday will prevail Sunday, with upstream
convection edging closer with the slow moving front. Convection will
fire over the rgv plains Sunday night with a few cells possibly
moving into the northwest sector of the cwa. The front will approach
the CWA on Monday, less emphatically than before, with winds
weakening and with some uncertainty as to whether the front will
have enough push to make it through. At any rate, the atmosphere
will be slightly destabilized resulting in an increase in rain
chances, particularly inland, where convection may fire late Monday
night into Tuesday morning. Southeast flow will regain its footing
on Tuesday and Wednesday, plus a destabilizing mid level low will
approach from the west, with diurnal showers firing over the cwa
while the lingering front is stalled or pushed back north. Only by
Thursday will rain chances settle down to the more benign coastal
sea breeze type, as the upstream low edges northeast. A weakness
above the southwest gulf may begin to trigger convection offshore
the latter half of next week.

.Marine (tonight through Friday night): seas were near 4 feet with
south to southeast winds near 21 knots at buoy020 this afternoon.

Moderate to strong south to southeast winds will prevail across
the coastal waters tonight as low pressure across the southern
plains and high pressure across the eastern gulf of mexico
provides a tight pressure gradient across the western gulf. Will
go ahead and extend the SCA for the bay waters through this
evening and post an SCA for the offshore for this evening through
fri morning. The pressure gradient will remain strong across the
coastal waters Friday and small craft advisories will be needed
for the laguna madre Fri morning and the SCA for the offshore
waters may need to be extended possibly through Fri afternoon.

Small craft advisories will be needed for the offshore waters for
fri night for strong southeast winds.

Saturday through Tuesday night: a persistent pattern of high
pressure will dominate the gulf during this period. Thus, look for
mainly moderate southeast winds and seas. Seas of four to six feet
will be common offshore, qualifying for small craft should exercise
caution headlines.

Bro watches warnings advisories
Tx... None.

Gm... Small craft advisory for winds until 9 pm cdt this evening for
gmz130-132-135.

Small craft advisory from 6 pm this evening to 7 am cdt Friday
for gmz150-155-170-175.

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.
