Discussion...

Short term [Sunday through Sunday night]
A very warm afternoon with temps in the mid 80s near the coast
and near 90 across portions of central and western areas. Expect
to see a few showers develop in the next hour or two across areas
along and SE of a columbus to conroe to livingston line, as
heating continues. A weak cool front(which is really just drier
air)is currently located from near act to tpl and will be near cll
around 7 pm. This boundary will provide an additional focus few
showers and possibly isolated thunderstorms overnight as it pushes
se. Expect this boundary to stall during the early morning hours
near or just south of houston. We may see some patchy fog near and
south of the boundary during the early morning hours. Another
very warm afternoon is expected on Sunday with MAX temps very
similar to what we are seeing today. Isolated afternoon showers
will be possible again on Sunday across much of the area.

Wood

Long term [Sunday night through Saturday]
Mostly cloudy skies are anticipated late Sunday night through
Monday as the next frontal passage approaches the region. Global
model guidance is in fairly good agreement with the overall timing
of the front, which is expected to reach our northern zones Monday
morning, and off the coast by the late afternoon to early evening
hours. Anticipate decent shower and thunderstorm coverage along
the boundary as it pushes through the area, with frequent
lightning, gusty winds, and brief heavy downpours possible with
stronger storms embedded along the boundary. The storm prediction
center has outlooked areas along i-45 and to the east and
northeast across our forecast area under a marginal risk for
severe storms. Precipitable waters surge to near 1.5 to 1.8 inches
ahead of the front. Additionally, CAPE values should peak near
2000-2500 j kg along and ahead of the boundary, with no mid-level
cap in place. The 850 mb jet will also increase to 35-45 knots
across the northeastern counties, essentially along i-45 and i-10
and to the northeast.

Behind the front, expect drier air to usher in as surface ridging
moves into the area. High temperatures for the days following to
peak in the 70s and low temperatures will also bottom out in the
low 50s to upper 60s. Moderate onshore flow should return by
Wednesday afternoon, bringing with it the return of higher
moisture values. The chance for showers and thunderstorms returns
Thursday, as a second cold front, stronger in nature, moves
through the region. The global model solutions diverge in regards
to the timing of this feature towards the the end of the week.

Most of the guidance pushes the front through sometime between
late Thursday through Friday. At this time the ECMWF remains the
fastest with this feature, pushing the front off the coast by
Friday morning, while the GFS lags behind about 3 to 6 hours.

Regardless, this front does look to be more potent, and the
weekend could be off the a chilly start with low temperatures
dropping into the mid 40s to low 60s Saturday and Sunday.

Aviation [18z TAF issuance]
18z aviation... Sct CU are expected this aft, with a few areas of
MVFR ceilings through 19z. Isolated to scattered showers are
expected to develop around sgr, iah, hou, and cxo between 21 and
22z, continuing through 1z. Only a very small chance of a
thunderstorm, so that was left out of the tafs. A weak frontal
boundary will approach cll this evening and is expected to make it
near or just south of hou before stalling around 11 or 12z. There
will likely be some shra near the boundary. Patchy fog is
possible around and south of the boundary during the early morning
hours.

Wood

Marine
Light to moderate onshore flow is expected to continue through
Sunday afternoon. There may be some isolated showers or
thunderstorms tonight and into Sunday morning that will produce some
isolated gustier winds. Southerly flow increases Sunday night into
Monday morning nearing caution flag criteria ahead of an approaching
cold front. Then, strong northerly winds will develop Monday night
into Tuesday in the wake of the cold front. The northerly winds
offshore may reach advisory conditions.

The coastal flood statement will continue for the gulf facing
beaches as tides area expected to again peak around 3.7 mllw
tonight and Sunday night.

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.
