Synopsis for the middle texas coastal waters.. Weak to moderate onshore flow will occur today and tonight. Onshore flow will increase to predominate moderate levels Tuesday afternoon in advance of an approaching upper level disturbance. Strong onshore winds will persist Tuesday night and Wednesday morning as a cold front approaches. There will also be a chance for showers and Thunderstorms. The front should move through the waters Thursday with weak to moderate offshore flow in its wake. Moderate onshore winds return on Friday as the next storm system moves into the southern rockies.

Discussion
Note aviation discussion below regarding 12z tafs.

Aviation
MVFR/ifr/lifr ceilings/visibilities early this morning will
transition to MVFR/vfr by mid morning thenVFR by afternoon.

Increasing onshore flow mid/late morning/afternoon. A transition
to MVFR/ifr ceilings/patchy ifr visibilities and light wind near
the end of the TAF period.

Previous discussion /issued 342 am cdt Mon mar 27 2017/
short term (today through Tuesday)...

concur with the deterministic gfs/ecmwf/nam that the upper level
disturbance currently over the SRN plains will lift e/ne while
another yet stronger upper level disturbance moves ewd across the
swrn CONUS during the period. Not surprised that the foregoing
deterministic solutions stall the frontal boundary just north of
the CWA today given the projected upper pattern. Do not expect the
front to trigger convection over the nrn CWA today given limited
moisture. Increasing synoptic scale ascent associated with the
stronger upper sytem will increase the chance for convection over
the cwa. Anticipate isold convection over the nwrn CWA Tuesday
afternoon given upper forcing and near/above normal pwat values
(gfs ensemble QPF output also adds credence.) increasing onshore
flow will result in at least scec conditions over the msa Tuesday
afternoon. Based on wavewatch sea state output/expected wind
velocities, anticipate a low risk for rip currents today and a
moderate risk Tuesday.

Long term (Tuesday night through Sunday night)...

moist southerly onshore flow will persist Tue night in advance of a
deepening cyclone over the southern rockies. Convection ongoing
along the dryline in west texas may approach our far NW counties
late. A few strong storms will be possible. Will maintain highest
pops for the northeast coastal bend for Wednesday morning due to
forcing ahead of the dryline. An isolated strong/severe storm will
be possible due to capes (>2000 j/kg), bulk shear magnitudes >35 kts
and 90kt upper jet nosing into the region. SPC has highlighted our
ne counties in a slight risk for Wed as well. Drier airmass advects
in on Thursday as the upper trough finally moves east and will
result in at least one cooler/drier overnight period. Low
temperatures Thursday night will dip in the upper 50s to lower 60s
area wide which is actually near normal for this time of year.

On Friday the next big trough digs into the southern rockies
inducing onshore winds once again... Which will become breezy by
afternoon. Moisture really surges into the area on Saturday as the
trough gets closer. Could be a few streamer showers by afternoon
with help from a few mid level impulses traversing the area in the
sw flow aloft. Better chances for rain can be expected sat
night/Sunday as the main forcing associated with this deep low moves
across the state. The added cloud cover and precip will limit
temperatures to more seasonable normals by Sunday.

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 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.
