Area Forecast Discussion
National Weather Service Houston/Galveston TX
951 AM CST Sun Dec 10 2017

.UPDATE...
Water vapor imagery shows the dry air aloft beginning to be
eroded from the west this morning, as high cirrus moves into the
western reaches of our forecast area today. With surface high
pressure lingering overhead, plenty of sunshine should help
temperatures rise into the mid to upper 60s today across SE TX.
Dewpoints are should remain in the mid to upper 30s, but will be
on the rise come Monday. Only adjustments made to the forecast in
this morning`s update were for temperatures and dewpoints to
account for observations. Otherwise, forecast appears to be in
good shape.

.PREV DISCUSSION... /ISSUED 533 AM CST Sun Dec 10 2017/

AVIATION...
VFR. A variable breeze around the western dial through the period
as high pressure nestles in across the region. Late day western
cirrus may ride in along the (exiting) backside of the eastern
CONUS upper trough axis. 31

PREV DISCUSSION... /ISSUED 328 AM CST Sun Dec 10 2017/

DISCUSSION...
Southeast Texas will see some high clouds stream across the area
from the southwest and west over the next couple of days as a mid/
upper level low lingers around the Baja Peninsula. After another
cool start to the day (3 AM temperatures range from the low to
mid 30s inland to around 50 along the coast), look for warming
daytime high temperatures today and Monday as surface winds come
back around to the west and southwest. Moisture levels remain
very low, and still expect to see no rain when the next fast
moving cold front moves through the area Monday night through
early Tuesday morning. Slightly cooler temperatures can be
expected behind this front. Winds come back around to the south
and southwest on Wednesday before another cold front moves
through the area on Thursday and Thursday night. The upcoming
week`s fronts will help to keep western Gulf of Mexico moisture
levels on the low side, and have leaned toward the more consistent
and drier ECMWF model runs for next weekend`s forecast. At this
time, anticipating the deeper moisture levels and slightly better
rain chances to be concentrated off to our northeast.  42

MARINE...
Overall, this week`s maritime weather will be fairly uneventful with
a couple of passing cold fronts veering and slightly strengthening
offshore flow for brief periods. An early Tuesday cold frontal
passage will veer a weak early week westerly wind northerly and
increase these winds to brief cautions across the Gulf. Eastern
moving high pressure will take light flow and swing it back to
onshore by Wednesday afternoon. Winds will veer around the dial late
in the work week...becoming moderate northerly again (SCEC) with an
early Friday frontal passage. Weekly seas will pick up by a couple
of feet with each frontal passage...late week slight precipitation
chances Thursday and Friday in association with the approach and
passage of the early Friday cold front. Weekend winds will be
onshore and strengthen to caution levels as the pressure gradient
tightens between Florida high pressure and lowering Rocky Mountain
lee pressures. 31
