area forecast discussion
national weather service brownsville tx
444 am cdt Mon may 27 2019
.Short term (now through Tuesday): mid to upper level ridging will
continue across the southeast u.S. With persistent troughing and
unsettled weather over the desert southwest. A closed high noted in
the 500mb flow over the northern gulf has broadened and extended
westward into deep south texas. This will maintain hot and dry
weather through the short term. Model time-heights indicate very
shallow moisture, with strong subsidence above 850mb. This will make
it very difficult for any showers to develop across the region.

Radar imagery this morning shows some weak showers trying to stream
northward over the waters, but they will have trouble surviving
inland. Have maintained 10% pop along the coast and offshore today
with around 5% elsewhere. Similar conditions on Tuesday with above-
normal temperatures and very low rain chances.

.Long term (Tuesday night through Sunday): for this portion of the
forecast, 500 mb high pressure will be the dominant force over the
entirety of the gulf of mexico, deep south texas, and the rio
grande valley. This synoptic situation will produce dry weather
for the bro cwfa during the period. However, some model guidance
suggests that precipitation may occur within the forecast area on
Friday and Saturday courtesy of the quick passage of weak mid-
level disturbances. This forecast versus model difference will
need to be monitored by successive forecast shifts, even through
precipitation amounts would likely not be appreciable.

Temperature-wise, the presence of the 500 mb high will support
well above normal daytime high and overnight low temperatures for
the entire forecast period.

.Marine (now through Tuesday): a strong pressure gradient between
surface high pressure over the northeast gulf of mexico and low
pressure troughing across west texas will result in periodic
hazardous marine conditions through at least the first half of the
week. Small craft advisories will be possible on Tuesday across the
gulf waters as seas build to 5 to 7 feet.

Tuesday night through Sunday: small craft advisory conditions
will prevail along the lower texas coast Tuesday night through
Wednesday night courtesy of an enhanced pressure gradient. Much
improved winds and seas will occur Thursday through Sunday as
the gradient weakens and high pressure becomes a more dominant
force over the western gulf of mexico.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
