GMZ100 Synopsis For Baffin Bay To Rio Grande Out 60 Nm- 357 Am Cdt Wed Jul 17 2019
Synopsis..Modest pressure gradient between a broad surface ridge across the gulf of mexico and thermal troughing over the interior mountains will result in mainly moderate southeast winds through this weekend. These winds may become fresh during the daytime on the laguna madre, however. Moderate seas early on trend toward slight over the weekend as winds diminish slightly with weaker high pressure stretching across the gulf.

356 am cdt Wed jul 17 2019
.Short term (today through Thursday): mid july in the rio grande
valley and deep s. Texas is living up to its expectedly hot
billing, with fair weather the rule. About the only difference
from average is the persistence of the breezy southeast flow,
courtesy of the surface high parked over the northeast gulf
combined with "heat" trough from the foothills of the rockies
south to the sierra madre. These surface features are the result
of slightly stronger 500 mb ridge over the southeast u.S. Than the
one over the southwest u.S. So, while daytime temperatures are
right around mid july averages (mid 90s lower valley, 99 to 103
elsewhere), just enough overnight breezes will keep the sultry
temperatures in the 80s for most of the night (with heat index 88
to 97) falling into the upper 70s to lower 80s by daybreak... In
this case, values 3 to 6 degrees above average. Daytime heat index
will continue to range from 105 to 110. No rainfall is expected
on land... Which is keeping moderate to severe drought going across
the rio grande plains and beginning to turn recently green
grass rangeland brown in the lower valley mainly east of us
77... Where the june 24th rainfall was notably lower than
along west of us 77.

.Long term (Thursday night through Tuesday): the beginning of the
long term period will remain under the influence of a broad 500
mb ridge across the southern us. This ridge will continue the
persistent pattern of slightly above average temperatures with
peak afternoon heat indices between 105 and 110 degrees. After
Saturday, local 500 mb heights and 1000 to 500 mb thicknesses
gradually drop into early next week. A few of the recent model
runs, especially the ecmwf, have highlighted a weak piece of
energy splitting off an upper level trough along the east coast
and creating a weakness aloft across the western gulf. Overall,
anticipate for the temperatures to gradually decrease to near
climatological average for early next week and lower peak heat
indices in the afternoon as well.

Interaction between a surface high pressure system over the gulf
of mexico and broad low pressure over the mexican higher terrain
will continue to result in moderate to breezy south-southeast
winds into the weekend. The pressure gradient and winds will
subside early next week as a front moves into the north-central
half of the state. With weaker wind speeds and some uptick in
the moisture across the 850 to 700 mb levels, will promote the
potential for sea breeze convection along with offshore showers
and thunderstorms early next week.

.Marine (now through Thursday): persistence is the forecast
through Thursday, based on the aforementioned southeast flow.

Upwelling has been a return feature the past several days and is
helping to knock down nearshore wind speeds, at least out 10
nautical miles. General marine layer, while weak, should keep
average winds right on the edge of caution (15-20 knots and gusty)
beyond 10-20 nautical miles out at night, but speeds should be
closer to 13-17 knots by day. Laguna madre winds, meanwhile, will
continue to jump up close to 20 knots and probably a smidge higher
across the land cut in kenedy county, so will continue the
exercise caution wording for the daytime hours.

Seas have also been persistent, and will continue a broad 4 foot
value for most waters. Could see a few hours up to 5 feet in some
areas especially beyond 20 nm out. Wind waves continue to be
dominant (3 feet overall) which is a nuisance to boating but not
necessary a show-stopper for all.

Thursday night through Tuesday: moderate onshore winds and seas
will continue into the start of the weekend. This may result in
small craft exercise caution to marginal small craft advisory for
winds conditions on the bay during the afternoon evening. The
pressure gradient over the region will gradually weaken from
Sunday into early next week as a front slides into north-central
texas. Winds gradually diminish and seas subside as a result.

However, shower and thunderstorm chances will increase early next
week and may result in locally gusty winds and agitated seas at
times.

Fire weather Conditions across the rio grande plains of jim hogg
and zapata county are right on the edge for a fire danger statement
based on the combination of dry to critically dry fuels and
marginally low humidity and 20 foot winds right around or just above
15 mph. For now, with the forecast parameters at or just below
local criteria for a statement will hold off but let later shifts
take a closer look. Key will be dewpoint temperatures, which on
Tuesday stayed just above 60 and kept afternoon humidity from
dropping into the lower or mid 20s. Should additional dry air mix
down and bring dewpoints into the upper 50s while high temperatures
reach the lower 100s, humidity would be sufficient for at least a
fire danger statement.

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.
