Area Forecast Discussion
National Weather Service Houston/Galveston TX
311 AM CDT Tue Jul 25 2017

.DISCUSSION...
Under partly to mostly cloudy skies, early morning temperatures across
Southeast Texas are in the mid to upper 70s inland and in the lower
80s at the coast. These readings are actually a degree or two cooler
than they were at this time yesterday. Radar is quiet at the moment,
and the forecast has it staying that way today as we lose our recent
2+ precipitable water values with mid/upper level ridging beginning
to build into the area. Some moisture from a western Gulf of Mexico
mid/upper level could work its way into our area on Wednesday, so will
maintain low rain chances that are already in the forecast. Will keep
Thursday and Friday mostly dry, then bring some rain back into the
forecast beginning over the weekend and possibly continuing into the
start of next week as a western U.S. ridge and eastern U.S trough allows
a weak frontal boundary to slowly sag southward into the area. If this
boundary lingers in/around our area early next week, parts of Southeast
Texas could end up getting some decent rainfall coverage. If it manages
to move far enough southward, much of our area could end up drier.

Rising heat index values will be the weather story for the rest of the
week, and heat advisories might be needed as values are expected to
get closet to our 108 degree threshold. Even if no advisory is in effect,
precautions should always be taken at this time of the summer to keep
people and pets safe from the heat.  42

.MARINE...
Typical summer marine conditions are expected for the next several
days with light/moderate southerly winds and lower end seas. Speeds
may flirt w/ caution tonight for a few hours. Winds should veer more
to the sw going into the weekend ahead of a weak frontal boundary
backdooring into se Tx.   47

.AVIATION...
Cirrus and/or dust will continue to create BKN cigs at 15000-25000
feet with no significant impact expected. Could get a brief window
of MVFR cigs around sunrise but impact should be an hour or less and
coverage will be spotty so will hint at the lower cig with a sct015-
sct025 deck in the morning. Some spotty cumulus clouds possible in
the afternoon but persistent upper level clouds should prevail
through the TAF period.  47
