GMZ100 Synopsis For Baffin Bay To Rio Grande Out 60 Nm- 929 Pm Cdt Sun Sep 23 2018
Synopsis..A weak cold front is located well offshore of the lower texas coast with light and variable winds behind it. Models are struggling with its position through tonight and predict it possibly retreating back towards the coast. The boundary should be fairly weak regardless that southerly winds will prevail. Southeast winds will be reestablished across the western gulf as surface high pressure builds back into the eastern gulf. Another cold front may approach southeast texas towards the end of the week, which will increase moisture and rain chances Wednesday through Friday.

Discussion Updated for latest aviation discussion below.

Aviation ExpectVFR conditions to prevail for all three taf
sites in deep south texas. Winds overnight will be light and
variable, however, should increase to around 10 knots or so from
the south or south southeast tomorrow morning through the end of
the cycle.

Prev discussion... Issued 241 pm cdt Sun sep 23 2018
short term (now through Monday night): the most recent surface
analysis indicated a cold front over the western gulf of mexico.

In the wake of the front, kbro doppler radar is completely devoid
of echoes, with satellite imagery showing gradually thinning high
cloudiness moving northeast out of neighboring mexico. Tranquil
conditions are anticipated through the forecast period as surface
high pressure builds in from the east and mid- level high pressure
makes a halfhearted attempt to build in from the same direction.

In the wake of the first cold front of the season, temperatures
will finally range in the near normal level for a change.

Long term (Tuesday through Sunday): the global models appear to
continue to show considerable differences as far as rain chances
this week with the ECMWF wetter than the GFS Wednesday and
Thursday. The GFS progs drier air across southwest texas Tuesday
than the ECMWF so will initially lean towards the drier gfs
through the next several days. The models are at least in
agreement with the 500mb trough across central united states
Wednesday and moving slowly eastward Thursday as a weak cold
front moves into northwest texas Wednesday and into south texas
Thursday before stalling. Moisture will pool along and ahead of
the boundary across south texas providing a chance of showers and
thunderstorms across the CWA Wednesday through the rest of the
week. The front will wash out and moisture across the area will
lift northward for the weekend so will mention a slight chance of
rain Saturday and Sunday mainly for seabreeze convection across
the coastal sections.

Marine (now through Monday night): buoy 42020 reported west-
northwest winds around 6 knots gusting to around 10 knots with seas
slightly over 1.5 feet with a period of 6 seconds at 1350 cdt 1850
utc. Favorable winds and seas are expected along the lower texas
coast in the wake of the recent passage of a cold front. Small craft
exercise caution and small craft advisory are not likely to be
needed.

Tuesday through Friday... Light to moderate south to southeast winds
will prevail across the coastal waters Tuesday with low pressure
across west texas and high pressure across the eastern gulf of
mexico. The pressure gradient will remain weak across the lower
texas coast Wednesday as a weak cold front moves into northwest
texas. Winds should diminish Thursday as the front moves into
south texas and stalls. Light southeast to east winds will
prevail across the coastal waters Thursday and Friday as a result.

Bro watches warnings advisories
Tx... None.

Gm... None.

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.
