See aviation discussion below for the 06z tafs.

Vfr will prevail through the period. Gusty northerly winds will
persist overnight in wake of a cold front. Winds will gradually
veer to the northeast through the day Sunday, maintaining a moderate
breezy flow. By the late afternoon evening Sunday winds will drop
to a light flow while continuing to veer.

Previous discussion issued 551 pm cst Sat nov 18 2017

see aviation below for 00z TAF update.


a cold front is currently pushing through the region. This will
bring windy conditions this evening through tonight, with gusts
around 25 to 30 kts. Winds will gradually relax early Sunday
morning, but maintain a moderate flow through the period as the
flow shifts from the north to a more north northeast flow.VFR
will predominate through the period.

Previous discussion... Issued 332 pm cst Sat nov 18 2017
short term (tonight through Sunday night)...

the cold front is on its way south expected to push offshore around
6 pm this evening, with far western extension already moving through
cotulla and approaching victoria as of writing. Winds have veered
out of the SW ahead of the front due to a prefrontal trough.

Farther south along the coast, winds continue to remain variable
and light, especially now that the warm temperatures across the
southern coastal bend have aided in the weak sea breeze
development along the coast with winds starting to back out of the
south-southeast. But winds will become northerly with the frontal
passage. As the front moves down, initial winds will increase
with gusts of 25 to 35 mph, but should relax slightly heading into
the evening. Over the waters, however, winds are expected to
remain strong with frequent gale force gusts. Not expecting rain
to develop over land due to the persistent SW warm and dry flow
coming off the sierra madre ahead of the front. However, isolated
showers will be possible once the front makes it over the gulf
waters. Activity will be brief as the front will quickly push
farther south across the waters this evening.

Temperatures tonight are expected to cool into the mid to upper 40s
as cooler and drier air moves in. For Sunday, continued CAA will
lead to temperatures struggling to break out of the 60s, with the
exception of a few locations toward the southern coastal bend that
may reach around 70 degrees. Thin cirrus will begin to move in
from the west through the day on Sunday.

Chillier conditions are then expected for Sunday night as winds by
this time will have relaxed further. A few locations for Sunday
night may reach into the upper 30s especially in low lying locations
from cotulla to victoria.

Marine (tonight)...

strong northerly winds will develop in wake of the cold front this
evening. Gale warnings are in effect for the gulf waters as very
strong winds aloft are expected to mix down to the surface over the
warmer waters. For the bays, small craft advisories are in effect.

Winds will be strong out of the north, but gusts are not expected to
frequently reach gale force wind speeds.

Long term (Monday through Saturday)...

there will be a brief period of onshore flow for Monday as the
surface high pressure ridge moves to the east. Adequate moisture
over the coastal waters along with a very weak coastal trough could
generate isolated showers in this area Monday night into Tuesday. A
short wave trough will be diving southeast through texas Tuesday
morning and reach the northwest gulf of mexico by Tuesday evening.

Isolated to scattered showers will be possible mainly over the
offshore waters Tuesday night as this short wave trough moves
through. Another surge of high pressure will move through the area
Tuesday night with offshore flow increasing to SCA levels Wednesday.

It will be cool and dry for thanksgiving. Temperatures will warm
back to near normal levels by Saturday as upper level high pressure
ridge over mexico builds into south texas.

If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at 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.
