pronounced middle/upper low over the Sierra mountain region will
continue to dig southward into the southern Great Basin where it will remain
through the weekend. This will maintain broad southwesterly flow aloft
across the Southern Plains and supply ample moisture. In
addition...Hurricane Sandra over the eastern Pacific will continue to
churn northeastward and make landfall as a ts over Mainland Mexico early
Sunday morning...with broad feed of associated tropical moisture
spreading into Texas through the weekend. Low level Gulf moisture
return is well underway across the lower and middle Texas coast this
afternoon which will overspread the rest of the Upper Texas coast
over the next few days. The net result will be mild and unsettled
weather over southeastern Texas into the weekend.

As moisture return overspreads the area we can expect a general
increase in rain chances...mostly as scattered showers Thursday
and Friday increasing to steadier rain in the northern counties
Friday and Saturday. Will keep chance probability of precipitation over the western counties
beginning tomorrow morning where hrrr spreads some light showers
out of central Texas. However...for all but the immediate coast and
southeastern counties...primary rain chances begin Friday morning and
continue into Sunday. While the heaviest rain will likely occur to
the north and west of southeast Texas...some areas north of a
Columbus-Conroe-Livingston line could still see rain totals from
1-2" between Friday and sun. Much of the Houston metropolitan into the coast
are expected to see lesser amounts.

Temperatures will be quite warm for this late in Nov with
afternoon highs approaching 80f for a few spots Thursday and
Friday...prior to the cold front sagging across the area Saturday.
Behind the front we will likely cut temperatures 20 degrees for highs by
Sunday. We look to remain below normal through next week...with
unsettled weather continuing as moist westerly flow aloft remains in



for tonight...will continue to carry caution flags for the offshore
waters due to the elevated winds and higher seas. Nearshore water
forecast will carry winds around 15 knots...but add another knots or
two and caution flags will be needed there too. Slight increase in
both winds and seas is still anticipated tomorrow and Friday.
Advisories will likely be needed offshore...and caution flags are
expected for the nearshore waters and maybe the bays too. Expect
gradually lowering winds and seas over the weekend with the approach
and passage of a cold front. This front is currently expected to move
into the waters late Saturday night or early Sunday morning and
through the area during the day on Sunday. At this flags
are anticipated behind this front due to the low enough wind and sea
forecast. Will continue to monitor for possible sea fog formation
over the next couple of days. Also...elevated tides and expected to
