area forecast discussion
national weather service brownsville tx
240 pm cst Thu nov 15 2018
.Short term (tonight through Friday night): with the exception of
an axis of high clouds moving across the cwfa this afternoon, not
much in the way of weather to report today. Aloft, generally
confluent flow (sinking) exists across much of the central us
(minus a weak impulse helping with the aforementioned cloud axis
right over our area this afternoon). At the surface, high pressure
is mainly in control which is keeping the low levels cool... Yet
dry. This high pressure will eventually drift eastward over the
gulf later tonight and especially during the day Friday. At the
same time another weak impulse will drop into the red river valley
and flatten tonight through early Saturday. At this time, not
expecting much with this impulse except maybe scattered higher
clouds, especially across the northern ranchlands.

Eventually the flow aloft will become progressive (zonal). As the
surface high continues to shift eastward across the gulf, southerly
return flow will start once again. This will help gradually increase
temperatures and moisture levels toward the end of the period.

Otherwise, below average temperatures (though not as cool) will
continue through the short term along with mostly light and variable
winds.

.Long term (Saturday through Thursday):as nice as the short term
will be and has been the complete opposite is expected for much
of the long term. A developing split flow pattern across the conus
is likely to result in a wet and relative cool to mild period for
the rgv and deep south texas. The first element is a cold front
expected in the CWA some time Sunday night into Monday as energy
within the northern jet moves out of canada through the rockies as
an upper ridge strengthens over the pacific NW british columbia.

This front is followed by a series of mid level troughs embedded
within the subtropical southern jet stream flowing from the
pacific, under the ridge, across the desert SW and into texas.

12z model suite remains in good consistency with the Sunday
night Monday frontal passage along with a initial burst of
convection and potential widespread moderate rainfall as gulf
moisture, upwards to 650mb, will be in place. As the relative
cooler air (highs 50s and 60s) settles to the surface
Monday Tuesday the first of two shortwave troughs, in the southern
stream track across the state. This will allow for our usual
coastal troughing to develop maintaining a chance of rain, likely
drizzle and light rain, with low thick clouds to keep temperatures
from recovering much. Next disturbances rides on the heels of the
first working its way into texas later Wednesday and thanksgiving
day. GFS is much stronger than the ec but both models trend
slightly lower on rain chances and warmer temperatures, however
with the thick cloud cover likely to linger and a resurgence of
north winds next Thursday will trend closer to the cooler ecmwf
temperatures which is a few to several degrees below current model
blend and previous local forecast projections.

.Marine:(tonight through Friday night): overall, favorable marine
conditions expected through the short term marine period. High
pressure will remain in control, which should keep winds very light.

Seas around or less than 2 ft expected. The high will eventually
shift eastward with time allowing for a light southerly flow to take
shape. This may bump wave heights just slightly toward the end of
the period, however, winds will remain mostly light (5-10 kts
generally).

Saturday through Tuesday... Moderate southeast flow and slight seas
over the weekend to be followed by a mild cold front Sunday night
and Monday with its impact persisting through Tuesday. A coastal
trough is forecast to develop Tuesday and possibly persist through
thanksgiving day. Not expecting any hazardous marine conditions over
the weekend but in wake of the front Monday and Tuesday small craft
advisory conditoins are possible for all or portions of the coastal
waters.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
