Short term (tonight through Saturday night)
Any isolated convection over northeast sections of the area will
wane with the loss of daytime heating. Some showers may redevelop
over the gulf waters late tonight into early Saturday morning.

Overnight lows will range from the 70s inland to low 80s along the
immediate coast.

On Saturday, inverted trough will continue to move westward across
the gulf. Being on the western side of this disturbance, most
locations should remain dry. The exception may be across coastal
bend into victoria crossroads where deeper moisture will reside
(pws around or slightly above 2 inches). Will keeps pops in the 20
to 30 percent range as daytime heating and the sea breeze may
trigger some isolated convection. The heat will be an issue again
on Saturday with highs between 100 and 105 over the western brush
country and rio grande to middle 90s near victoria. The hot temps
combined with the humid conditions will produce dangerous heat
index values. A heat advisory may be needed across portions of the
area, especially southern coastal bend.

Similar trend is expected tomorrow with convection subsiding during
the evening, but isolated showers then redeveloping overnight
over the gulf waters. Lows again will be in the 70s inland with
low 80s along the coat.

Long term (Sunday through Friday)
Surface low pressure across the southern high plains and high
pressure across the northern gulf will maintain a more moderate
onshore flow across the gulf waters through early next week, with
breezy conditions in the afternoons inland. A weak shear axis will
remain along the texas coast Sunday, but moisture is lacking so have
cut back on pops for Sunday and Monday. Mid level ridging builds
back to the south Tuesday, but at the surface, moisture increases
across the middle texas coast on the western periphery of the
surface high. This will bring back chances for isolated to scattered
showers and thunderstorms beginning Tuesday, with most activity
being thermally driven. Temperatures through the period will remain
hot, with the humidity leading to temperatures to feel like 105 to
109 degrees daily across the majority of south texas. Some locations
may reach 110 or greater which may require heat advisories on and
off through the week.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
