GMZ300 Synopsis For High Island To The Matagorda Ship Channel Out 60 Nautical Miles Including Galveston And Matagorda Bays 405 Am Cdt Fri Jun 23 2017
Synopsis for high island to matagorda ship channel out 60 nm.. Moderate southerly winds should slacken some later this morning, but 6-7 foot seas will likely stick around for most if not all of the day today and into tonight. For this reason, the small craft advisory was extended for the offshore waters through 3 pm this afternoon with a scec in place after that lasting into tonight. Winds and seas will continue to slowly diminish into the weekend, with periods of moderate onshore flow and elevated seas returning around midweek.

Discussion See aviation section for 12z tafs.

Aviation Satellite imagery shows a band of broken clouds along
highway 281 as well as scattered-broken cloud deck from the gulf
waters extending northward to near vct area. MVFR ceilings will be
possible over much of the coastal plains through 15z. Then expect
few to scattered clouds the rest of the day with gusty south winds
by 15z backing to southeast over the southern coastal bend this
afternoon. Strongest gusts will be over the southern coastal bend
this afternoon. Low level moisture will increase tonight and
expect MVFR ceilings to develop over the coastal plains by 08z
Saturday and reach lrd area by 10z.

Previous discussion issued 336 am cdt Fri jun 23 2017
short term (today through Saturday)...

the upper ridge will continue to hold to our west through tonight
with the main story for today being the dangerous heat index
values possible this afternoon. With a moderate onshore flow,
higher boundary layer moisture has advanced back into the region.

Dewpoint temperatures are in the upper 70s over the coastal plains
and do not expect values to fall very much by this afternoon.

Even though high temperatures will be a category or two lower
today than yesterday for the coastal plains, higher humidity will
lead to higher heat index values. Heat index values will range
from 110 to 115 across the area with values as high as 118 at
kingsville due to the influence of air flow from baffin bay. A
heat advisory will be in effect from 17z until 00z Saturday.

Expect laredo to reach another record high today.

Humid night expected for tonight. Lowered pops to 10 percent
during the overnight hours over the coastal plains and near shore
waters. Could see isolated streamer showers along the coast as
low level lapse rates will be barely adequate overnight.

Will see a relief from the heat by Saturday as the upper ridge
shifts slightly to the west. This will allow a front that pushes
down into northwest texas this evening to move through central
texas on Saturday and be near the i-10 corridor by 00z Sunday.

Higher moisture pooling in advance of the front will lead to
possibly scattered convection from the victoria crossroads into
the coastal bend. Expect only isolated activity over the brush
country. Higher moisture will also be moving into the coastal
waters to provide a chance of convection there Saturday.

Marine...

mesonet sites continue to show SCA conditions over the bay waters
south of port aransas this morning. There are even some strong
winds around rockport, but most of the bay waters north of port
aransas are at scec levels. SCA conditions will continue over the
gulf waters this morning with winds speeds expected to decrease by
this afternoon. Will take some time for seas to diminish to below
sca by late afternoon. Thermal gradient will keep SCA conditions
over the southern bays through the afternoon.

Coastal...

tide levels are down to around a foot above expected at bob hall
pier and port o'connor early this morning. Trend continues to be
slowly downward but with moderate to strong onshore flow this
morning, may see a slight increase. But even with tides of
slightly above 1 foot over expected possible, tide levels will
only reach 1.5 feet msl at port o'connor during high tide. Made
some adjustments to the coastal flood advisory, limiting the
advisory to port aransas down to baffin bay and have the advisory
expire at 18z today. Removed the inland counties of refugio and
san patricio counties also. Bay levels are running around 1.3 feet
above expected. But this also will not lead to bay levels
reaching 2 feet in this area around high tide.

Swells are expected to be 3-4 feet today with periods of around 8
seconds. With most of the day experiencing a moderate to strong
long shore flow, will keep rip current risk at moderate for today.

Long term (Saturday night through Thursday)...

deep moisture (pwat around 2 inches) will overspread the area early
in the period. A weakening boundary will drop in from the north and
while it may not make it into the area it still will help provide a
little lift to enhance precip cvrg. Aloft we'll be in an area of
relative weakness in the mid-levels which should further enhance the
convective profile each day. With all this considered we'll
continue a few days (sun-tue) of relatively high pops across the
area with best chances over and close to the gulf. Pcpc clouds and
lower heights will all help keep temperatures suppressed to at or
below normal values for highs into the early part of next week.

The atmosphere begins to dry out inland on Wed Thu hwvr deep mstr
remains over near the waters. Will maintain low pops east through
the period. Temperatures will slowly warm as things dry out and
heights rise.

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.
