Update
Breezy and dry conditions are settling in across the region in
the wake of last night this morning's cold front, which morning
surface analysis shows has pushed off the texas coast. Current
forecast is handling trends well, but did a minor update to
account for slightly drier conditions this afternoon based on
upstream dew points and anticipated afternoon mixing. Expect
elevated fire weather conditions across the area by early
afternoon as relative humidities fall into the 20-30 percent range
with conditions improving by this evening as winds decrease with
the arrival of surface ridging from west texas. Otherwise, expect
high temperatures to climb into the upper 60s to low 70s under
sunny skies.

front is in the process of moving thru the area. Lack of
instability and some capping has limited areal coverage and
intensity. Precipitation should be near or off the coast by
sunrise... Taking the sea fog with it. Clearing skies and a much
drier airmass will filter in during the day allowing rh's to dip
into the 25-30% range during the day with NW winds 10-20 mph.

Elevated fire weather conditions are possible.

Dry, seasonable weather will persist into the mid-late work week
time period with surface high pressure dominating area wx.

Moisture levels and rain chances will increase going on into the
weekend as onshore winds resume as the high moves off to the east.

The next western trof will advance into the plains and send a
cold front and associated precip through the area sometime
Saturday. 47
marine...

sea fog showers currently lingering over the area is expected to
move out by mid morning with the passage of the weak cold front.

Winds behind this front not terribly impressive per obs upstream
but with the continued CAA behind this boundary, we could see an
uptick with winds seas over the offshore waters this afternoon.

An scec has been issued for the 20-60 nm coastal waters for this
timeframe.

As the associated surface high builds down into the region tonight
and then makes a slow sweep across the southern states, winds will
be shifting to the east by tues and persisting through much of the
upcoming week. However, winds seas across the offshore waters will
likely continue to remain elevated and caution flag criteria could
persist through this week. SE winds expected to return to the area
late thurs Fri ahead of the next cold front that is still forecast
to move into the gulf waters late sat. 41
aviation...

scattered showers still possible through the rest of this morning

lematic at gls through mid morning. However, we are and will keep
seeing improving conditions from the NW as the morning wears on.

Vfr should prevail areawide by 18z. No cig vis issues for tonight
or tomorrow. 41

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.
