Update
Showers and thunderstorms continue to wrap around the periphery of
a surface high centered over the appalachians and upper level
ridging centered over the northeastern gulf coast. The majority of
this activity has been focused across southeast texas with the
heaviest rainfall occurring just outside of the lch CWA boundaries
in chambers and liberty counties. Hrrr and other high res
guidance indicating that this activity should continue through the
afternoon with storms remaining primarily over southeast texas
and the adjacent coastal waters. Thus, I raised pop's for both the
remainder of the morning and this afternoon across these areas.

Only other changes were minor tweaks to other parameters based on
latest observations. Expect convection to decrease over land
areas by late this evening.

Aviation...

a weak sfc trough over the tx coast combined with a shortwave
aloft is producing a band of shra tsra over southeast tx. Although
most of the activity is west of the area, some of this convection
will affect the bpt terminal today. Conditions have beenVFR
overnight under bkn ovc mid and high cloud decks, and these
conditions will continue today although CIGS will lower to
3500-5000 ft at bpt lch with sctd low decks further east. East to
southeast winds are also expected to strengthen to 10-15 kt at
bpt lch, with speeds around 10 kt at aex ara lft. Showers and
storms acrs southeast tx should diminish this evening, with cigs
lowering to MVFR at bpt after 06z.

prev discussion... Issued 405 am cdt Fri oct 20 2017
discussion...

high pressure at the surface and aloft will continue to dominate
the area into the early portion of the weekend. A few showers and
earlier some thunderstorms currently moving across E texas with a
weakening short wave. This will provide for considerable cloud
cover across the area today. Showers and thunderstorms will
continue to weaken as they try to move across the western portions
of the area today. Still cant rule out measurable rainfall over
southeast texas.

Low pressure still forecast to develop in the lee of the rockies
Saturday as a potent trough moves across the western us. This will
induce increasing moisture levels throughout the column. As the
features continue to move east, a cold front will move into the
region Saturday night and through the area Sunday. Instability and
shear parameters still indicate a potential for a few strong
storms Sunday.

Cooler airmass will follow in the wake of the front, however even
cooler airmass will come in the wake of a secondary dry front on
Tuesday with dry weather forecast for the remainder of next work
week.

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.
