GMZ100 Synopsis For Baffin Bay To Rio Grande Out 60 Nm- 348 Pm Cdt Sun May 26 2019
Synopsis..The combination of nearly stationary high pressure centered over the northeast gulf of mexico and persistent low pressure over west texas through the sierra madre oriental range will maintain moderate seas and moderate to gusty southeast winds through Monday. Low pressure will deepen Monday night through Wednesday, supporting stronger southeast winds and higher seas. Pressure differences will gradually weaken Wednesday night through Thursday night allowing winds and seas to slowly subside.

area forecast discussion
national weather service brownsville tx
346 pm cdt Sun may 26 2019
.Short term (tonight through Monday night): limited changes were
made to the ongoing forecast. A mid level trough with an embedded
low is over the west while the subtropical ridge is ensconced over
the southeast and the north gulf. The low will rotate slowly
through the trough over the west while the western extent of the
subtropical ridging will hold steady over the northwest gulf and
portions of east texas. Primarily dry weather will continue with
moderate to breezy southeast winds and a mix of clouds and Sun to
mostly sunny skies during the day while staying partly cloudy at
night. Mid to upper 90s will be the rule in temperatures across
the area on memorial day, slightly above normal, with a few spots
out west possibly hitting the century mark, and with mid to upper
80s at the beach. Heat index values may run between 100 and 105
degrees for a few hours across inland areas on Monday afternoon.

Overnight lows will be in the middle to upper 70s. There is a
moderate risk of longshore and embedded rip currents through
Monday evening.

.Long term (Tuesday through Sunday): the 500 mb pattern will be
shifting a bit in the longer range forecast period. The 500 mb
closed low over the desert SW will open up and will ride over the
top of the persistent ridge in place over the southeastern states.

After this closed low ejects out to the E and ne. A series of open
500 mb troughs will then follow this feature moving E over the top
of the ridge axis. This shift in the pattern will tend to weaken
the ridge axis a bit later this upcoming work week which may allow
for a slight lowering of the overall temps. Both the GFS and the
ecmwf appear to want to advect in a little bit better moisture
levels across the region. Meanwhile, the low level flow will
likely relax later this coming week as the pgf slackens. This may
set the stage for a little better sea breeze impact. However, am
not confident enough in this to mention significant pops later in
the forecast period and will maintain a mention of only silent
pops at this time.

Max and min temps will be a blend of the longer range model
guidance through day 7 8. Pretty good agreement is evident between
the GFS and the ECMWF through next fri. The GFS temps are then a
little cooler than the ECMWF starting next weekend. Overall
confidence in the forecast wording is above average at this time.

.Marine now through Monday night: the combination of nearly
stationary high pressure centered over the northeast gulf and
persistent low pressure over west texas through the sierra madre
oriental range will maintain moderate to fresh southeast winds and
moderate to high seas through Monday. Small craft should exercise
caution to low end small craft advisory conditions will be
possible. Low pressure will deepen upstream Monday night,
supporting slightly stronger southeast winds, and pushing wave
heights on the gulf more toward low end small craft advisory
criteria.

Tuesday through Friday night: as the surface low pressure areas
over the central plains states move out to the E and NE later this
week. The pgf will then start to weaken allowing for light winds
and lower seas after Wed night. Scec marginal SCA conditions may
be possible from tues through Wed night mainly for the lower tx
gulf waters.
