Aviation
Vfr conditions expected as a cold front moves toward the coast this
evening and offshore overnight. Could see some more shra and possible
tsra development along and ahead of the front through around 02z or
03z with the best chance of this happening near the gls and lbx sites
which could be close to the front intersecting with the sea breeze
boundary. Once the front gets far enough offshore, all locations will
have N winds 5 to 10 knots with just some cirrus streaming eastward
across the area. Cirrus possibly continues tomorrow while winds turn
a little more to the ne. 42

short term...

latest visible satellite imagery shows frontal boundary
stretching across SE texas just north of the houston area about to
enter harris county. Strongest storms are confined to extreme
east texas with a few isolated storm back towards liberty. More
robust line of cumulus stretches back to SE montgomery co and
should reach NE harris county the next couple hours. Forecast will
keep some rain chances along the front as it pushes south tonight
into tomorrow morning. Rain chances should be off the coast after
10pm to 1am tonight. Main threats from any isolated storms will
be lightning and gusty winds. Stronger storm if it forms could
produce hail but think SPC marginal risk highlights the small
threat for a severe storm with more of a threat over louisiana.

Cold front is pushing south tonight with it reaching the coast
around midnight and drier cooler air filtering into the are
Tuesday morning. Tomorrow may not necessarily be cooler with high
temperatures back into the mid upper 70s but it will feel drier
with afternoon rh down to 30 to 40 percent and light NE winds.

Long term...

main concern in the long term will be chances of thunderstorms
starting Friday through the weekend. One upper level trough
develops over the western u.S. And has a vorticity maximum split
of moving across the rockies quickly by Saturday morning. Second
trough now lags back and pushes across the plains next
Sunday Monday. Warm advection should bring back enough moisture
with the first approaching system to need rain chances Friday
morning. Better chances look to be Saturday as a cold front slides
into the area and then maybe again overnight Saturday into
Sunday. All of this hinges on the timing of the second trough. Gfs
is more aggressive with rain chances while ECMWF and canadian are
drier. It does look all of this should clear out Monday more in
line with the ecmwf. Still too soon to highlight any potential
weather threats, but there will at least be a chance for
thunderstorms Saturday and maybe Saturday night as convection
becomes elevated over top the front.

Overpeck
marine...

a cold front remains draped over SE tx this afternoon, and is
continuing to sag southward. Along this boundary, showers and
isolated thunderstorms will be possible. Light onshore flow will
eventually turn more out of the west and then out of the north
behind the passage of this cold front. Patchy fog will again be
possible across portions of the nearshore waters and bays this
evening, until drier air filters in behind the cold front.

Expecting to see improved visibilities shortly after midnight and
into the early morning hours Tuesday as the cold front clears the
coastal waters. Scec conditions are likely Tuesday morning into
the afternoon hours across the gulf waters, and as a result, seas
will rise to between 2 to 4 feet. East flow will prevail by
Wednesday, and eventually turn out of the southeast by Thursday
morning as onshore flow returns. At this time, another cold front
is anticipated to push through SE tx Saturday afternoon into
Sunday, with winds and seas expected to increase behind the front.

Additionally, tides will run around normal through the majority
of the week and start to run slightly above normal by about a half
foot to a foot towards the end of the week.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
