311 PM CDT sun Aug 30 2015

upper lows over southern Georgia and The Big Bend area of Texas
this afternoon. At the surface...high pressure ridging from the
Carolinas into eastern Texas. A weak trough...associated with the
remnants of along the western Florida coast. A couple
of thunderstorms over our western outer coastal waters...but
nothing much going on over southeast Louisiana and southern
Mississippi. Middle afternoon temperatures generally in the upper 80s
and lower 90s...with dew points in the middle 60s.


Short term...

Currently not planning on mentioning thunderstorms for this
evening...and expect the few storms in our coastal waters to
gradually weaken this evening. Georgia upper low will gradually
move toward the Atlantic coast over the next 48 hours while The
Big Bend low will move into eastern Texas. Have made very little
change to going forecast due to continuity with models and
neighbors forecasts. No mention of precipitation over land until a
slight chance on Wednesday. Temperatures within a couple of
degrees of normal...trending slightly warmer than normal. 35

Long term...

Weak upper low in East Texas will gradually set up over the area
for the end of the week...with differing details on when system
departs. Will go with consensus...which is scattered precipitation during
the day and isolated...mainly over coastal waters at night. Later
forecasts may need to bump probability of precipitation up a bit for Thursday through
Saturday...but should remain in the chance category. Temperatures
remaining close to normal. 35



Light winds and VFR conditions will prevail with the exception of
mcb where patchy fog may form and produce MVFR conditions after 9z
for a few hours. 12z mav/met guidance also indicate light fog
perhaps at btr and hdc...but with observation this morning not showing
anything less than 7 miles decided to leave it out for now.




Winds generally under 10 knots and seas of 1 to 2 feet with
occasional seas to 3 feet /mainly outer waters/ will prevail as a
weak pressure gradient dominants the weather over the Gulf of
Mexico. The only exception to this may be higher winds and seas
near scattered showers and thunderstorms that will return Tuesday
and be possible through the remainder of the week.
