GMZ200 400 Pm Cdt Mon May 22 2017
Synopsis for the middle texas coastal waters.. Generally weak onshore flow is expected tonight. Variable wind Tuesday. A frontal boundary oriented along the coast will remain nearly stationary tonight through early Tuesday and contribute to additional scattered showers and Thunderstorms. Additional shower and Thunderstorm activity will develop Tuesday in advance of a cold front. The cold front will move across the waters Tuesday night and result in a moderate north flow Tuesday night through Wednesday. Drier conditions will filter into the area behind the cold front. Onshore flow will develop and increase Thursday as surface high pressure moves across the northwest gulf of mexico and as surface low pressure develops over west texas.

Short term (tonight through Tuesday night)
Msas continues to depict the quasi-stationary boundary near and
parallel to the coast, and deterministic output maintain the
general position of this boundary tonight/early Tuesday before it
dissipates. Thus, anticipate additional isold/sct convection
mainly over the ERN cwa/msa tonight/Tuesday. Concur with the
gfs/ecmwf deterministic that an upper level disturbance will dig
s/se across the plains during the period and reinforce/maintain
the upper trough over the cntrl conus. In response, a cold front
is expected to move across the cwa/msa Tuesday night. This front,
significant moisture (nam determinsitic), and increasing upper
jet dynamics (gfs deterministic) should result in additional
convection Tuesday afternoon/evening in advance of the front.

Given the increased vertical shear and high CAPE values, strong
convection may occur. SPC has the CWA in a slight risk for severe
thunderstorms Tuesday. Increasing offshore flow expected Tuesday
night over the msa in response to frontal passage.

Long term (Wednesday through Monday)
Much quieter weather is expected by Wednesday in wake of the exiting
front. Northerly wind and drier conditions will develop. Cooler
temperatures will be felt briefly Wednesday but be most noticeable
during the overnight hours. South to southeast flow redevelops
Wednesday night with a gradual warming and increase in moisture
through the end of the week. Developing and deepening of surface low
pressure across the high plains Thursday will lead to breezy
conditions across south texas, especially the coastal bend and gulf
waters. Small craft advisories will be possible off and on starting
Thursday through the weekend. GFS and ECMWF models show sufficient
moisture returning over the weekend, with slight rain chances
possible by Sunday. The models also show another weak boundary to
move into the area early next week which would increase rain chances
heading into Monday.

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 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.
