Short term (tonight through Tuesday night)
Quiet conditions and generally westerly winds continue as high
pressure still has influence over south texas weather despite it
slowly moving south and east. High clouds will also continue to
stream in from the west moving with the jet stream. Another chilly
night is in store as temperatures cool into the lower 40s with a few
spots dipping into the upper 30s, especially in the lower lying
rural areas. The next cold front to make it to south texas is on its
way and currently moving through the texas panhandle. A 1034 mb high
forming in the high plains will help push the front farther south
this evening in order for the front to reach south texas shortly
before daybreak Tuesday morning. The atmosphere will remain dry with
pwats around 0.35 inch and keep mention of rain out of the forecast.

Northerly winds will develop behind the front Tuesday, becoming
breezy late morning through the afternoon. Weak CAA should allow
temperatures to cool a few degrees for Tuesday, with highs reaching
into the upper 60s versus the lower 70s of this afternoon. Overnight
lows Tuesday night should be cooler than tonight, with more areas
dipping into the upper 30s, with lower 40s along the immediate coast
and along the rio grande.

Fire weather
Breezy conditions are expected in wake of the cold front Tuesday.

Afternoon relative humidities are expected to fall below 35% for
a majority of south texas Tuesday afternoon, however at this time
winds are not expected to reach criteria for fire weather danger.

Continue to monitor for any possible changes.

Long term (Wednesday through Monday)
The extended part of the forecast will begin with high pressure
settled in over south texas. A significant cooldown is not expected
behind Tuesday's front with highs in the middle to upper 60s. A
slight warmup is expected on Thursday ahead of the next cold front.

Moisture is not overly impressive ahead of this front and any
chances of showers should be mainly confined to the gulf waters
Thursday night. Northerly winds will pick up Thursday night in wake
of the front and small craft advisories could become necessary for
the gulf waters. Temperatures will be set back about 5 to 10 degrees
on Friday with highs only in the lower to middle 60s. High pressure
once again quickly scoots to the east Friday night into Saturday
with southerly winds returning to south texas. Warmer conditions are
expected on Saturday with temps in the upper 60s to lower 70s. Some
discrepancies arrive during the weekend regarding moisture quality
ahead of approaching front on Sunday. Will keep 20 pops in the
forecast for Saturday night and Sunday, but confidence remains on
the low side.

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.
