national weather service brownsville tx
436 am cdt Mon aug 26 2019
.Short term (now through Tuesday): mid level ridging will build into
texas through the period. Drier air aloft will keep rain chances low
through Tuesday. Hot and humid conditions are expected today and
Tuesday with afternoon high temperatures ranging from the low to mid
90s near the coast and 100 to 105 degrees inland. Surface dew points
mainly in the mid to upper 70s, will support heat indices exceeding
110 degrees for much of the area, especially across the coastal
counties. Therefore, a heat advisory is in effect for portions of
the CWA this afternoon. Another heat advisory will likely be needed
for tomorrow with elevated dewpoints continuing. High pressure
across the eastern gulf combined with a thermal trough of low
pressure across west texas will support breezy southeast winds along
the coast this afternoon. Low temperatures tonight are expected to
be in the upper 70s to the lower 80s.

.Long term (Tuesday night through Sunday): 500 mb high pressure
dominating through a majority of the forecast period will allow
only a couple of bouts of isolated convection for the adjacent
gulf of mexico waters early in the period. However, as the mid-
level ridge of high pressure eases slightly and inverted 500 mb
troughs slip into the western gulf of mexico, isolated showers and
thunderstorms will be possible for the entire bro cwfa Friday
night through Sunday. Above normal temperatures will also occur
throughout the entire forecast period.

.Marine (now through Tuesday): high pressure across the eastern gulf
combined with a thermal trough of low pressure across west texas
will support moderate to strong southeast winds and moderate seas. A
small craft advisory is in effect for the laguna madre from 1 pm
until 8 pm today due to strong winds. Small craft exercise caution
on the gulf waters today due to elevated winds. The gradient is
expected to weaken on Tuesday.

Tuesday night through Sunday: light to moderate winds and low to
moderate seas are anticipated during the period as high pressure
dominates over the western gulf of mexico. Small craft exercise
caution and small craft advisory are not likely to be needed.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
