Area Forecast Discussion
National Weather Service Houston/Galveston TX
100 PM CDT Tue Oct 25 2016

VFR conditions expected to prevail at all terminals through this
evening with FEW-SCT cumulus developing during the afternoon, but
another round of patchy fog development is expected again for
terminals north and west of Houston IAH and HOU early Wednesday
morning. Have low confidence on how low visibilities will get
Wednesday morning as high clouds associated with a disturbance
moving east across the Southern Plains will help limit some
radiational cooling, but have included MVFR visibilities for
College Station, Huntsville, Conroe, Sugar Land, and Angleton. If
these high clouds clear out earlier than anticipated (HRRR
guidance indicating as early as 05Z for western terminals),
visibility timing and restrictions will need to be amended.
Otherwise light east to southeast winds with speeds less than 10
knots are expected through the period.

For the morning update, went ahead and lowered this afternoon`s inland
high temperatures a couple degrees based mainly on increasing cloud
cover. Some showers might be possible across parts of the coastal
waters and also in and around the Matagorda Bay area.  42

PREV DISCUSSION... /ISSUED 505 AM CDT Tue Oct 25 2016/

Clear skies, light winds and low T/Td spreads helping with the de-
velopment of patchy fog across SE TX this morning. With conditions
expected to be similar tonight/early Wednesday morning...we should
expect to see a repeat of the patchy fog. In fact, the rest of the
forecast for this week will be much of the same: warmish (slightly
above normal temps) with very limited to no rain chances.

A persistent surface high to the east will help to maintain mainly
light E/SE winds across the area the next several days. This patt-
ern of somewhat recycled air should keep low-level moisture levels
on the low side. Aloft, the ridge building from the west is progg-
ed to expand eastward and then flatten over the southern Plains by
the end of the week. Otherwise, our next best rain chances may not
be until the start of next week when the upper ridge shifts off to
the east and the next upper trof begins to deepen/move across from
the desert SW. 41

Easterly flow today will prevail through Wednesday before winds
gradually increase as well as seas with the passage of a disturbance
in the Gulf. Seas should build to 4-5 feet Thursday before winds
again relax Friday and Saturday.
