Discussion...
scattered showers and thunderstorms have developed today on the tail
end of an eastward moving disturbance. Those receiving the heaviest
rains have gotten a radar estimated 1 to almost 3 inches. Expect to
see decreasing coverage late this afternoon and on into early this
evening. Models are showing slightly higher precipitable water values
moving into the area tomorrow, and with a general weakness in mid/upper
level ridging, have gone with slightly better rain chances. Pops lower
at the end of the week and over the weekend under weak ridging and
slightly lower precipitable water values. Will carry increasing rain
chances next week as ridging aloft begins to break down and a western
U.S. Trough eventually works its way toward the east. 12z models are
not in particularly good agreement with the strength/location/movement
of this trough, so confidence is on the low side with next week's
forecast. Maybe we'll see a cold front move through the area toward
the end of next week? 42

Marine...
light to moderate southeast flow and seas around 3 feet are forecast
to persist along the Upper Texas coast through at least the next
week or so. Periods of showers and possibly a thunderstorm or two
will be possible over the waters through the forecast period, with
the best chances during the late night/early morning time frame
each day.
