.AVIATION [00Z TAF Issuance]...

VFR conditions with mostly clear skies across the TAF sites. Most
winds will stay light and variable and coastal with get some onshore
flow effects. Some winds will start shifting Thursday night with a
weak dry frontal boundary. 35

&&

.DISCUSSION...
Relatively quiet weather next several days with a couple of dry
cold frontal passages. Next week will monitor possible tropical
systems over the SW Gulf and possibly moving up into the Southern
Gulf from the NW Caribbean Sea but not expected to directly
impact Texas coast at this time.


.SHORT TERM [Tonight Through Friday Night]...
Tranquil and comfortable early fall weather has prevailed today
thanks to the strong mid-upper level ridge over southwestern CONUS
and a broad surface high pressure to our east. Clear skies and
light winds will again provide good radiational cooling tonight;
therefore, low temperatures will again range from the upper 50s to
low 60s.

Another quiet day is in store for Thursday. The main weather feature
will be warmer conditions ahead of an approaching weak cold front.
Temperatures will generally be in the mid to upper 80s. The dry cold
front sags southward into our region Thursday afternoon into Friday,
bringing drier air and shifting winds to the north-northeast. Gusty
winds from 15 to 20 knots will be possible along and behind the
front, mainly along the coast/over the waters. Dry conditions
remain in control into the weekend. 05

05

.LONG TERM [Saturday Through Wednesday]...
Will see continued dry weather through the period with surface
ridging and E to SE surface winds over the area. Models hinting at
tropical cyclone possibly in the Bay of Campeche...with
possibility of another lifting from the NW Caribbean Sea into the
southern Gulf by middle of next week. This especially true in the
GFS can Canadian models. ECMWF doesn`t do much with either. In
any case not likely to see either system impact Texas coast
directly given the forecast steering currents more to the NE...but
as always will have to keep an eye on how any systems behave and
track middle and late next week. 18


.MARINE...
Relatively light winds and modest seas next few days with surface
ridging and weak pressure gradient in place. A front will cross
the waters Thursday evening...with increasing NE flow behind it on
Friday. Relatively light winds are expected over the weekend but
will have to watch for any tropical development over the NW
Caribbean or Southern Gulf of Mexico...which could mean a
tightening of the pressure gradient and increasing winds and seas
next week.
