Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis for the middle texas coastal waters.. Tropical moisture will linger across the region for most of the day on Thursday, resulting in periods of showers and Thunderstorms mainly in the morning for the gulf waters. Shower activity is expected to move inland later in the day leading to decreasing chances for the gulf waters. Showers and Thunderstorms will decrease in areal coverage through Friday as drier air moves in from the north due to an upper level ridge. Deepening low pressure over west texas will result in moderate to possibly strong southerly flow this weekend. Sufficient moisture will be available Sunday and Monday for at least a slight chance for showers and Thunderstorms with the approach of an upper level inverted trough.

Discussion
Updated aviation discussion for 12z tafs.

Aviation
Wet conditions will continue across the eastern terminals this
morning. Light to moderate showers with MVFR, and at times ifr,
ceilings are expected to continue for the next few hours.

Tropical moisture will once again influence the region for most of
the day. This morning's shower activity is expected to shift
further inland by the afternoon, therefore have maintained some
mention of showers until this evening for all terminals. As the
low pressure system slides further to the southwest, rain chances
will taper off generally by 00z. Enough moisture will remain
around the area for MVFR ceilings to once again to develop
overnight.

Previous discussion issued 434 am cdt Thu jun 21 2018
short term (today through tonight)...

low pressure system with lingering tropical moisture will
continue to influence the region for most of today. Early morning
showers and thunderstorms will continue across portions of south
texas and the middle texas coastal waters. The heaviest activity
will remain across the southern portions of our cwa. Some areas,
mainly in nueces and kleberg counties, may receive an additional 1
to 2 inches of rainfall this morning and could lead to localized
flooding given the previous days' heavy rainfall. Have cut back
the ffa for our northern counties, but maintained it for the
southern counties through the afternoon. The shower activity is
expected to push inland this afternoon as the low pressure system
slips southwestward into mexico through the period. As the low
retreats, drier air is expected to advect in from the northwest
with a building ridge and rain chances will begin to taper off by
this evening. Otherwise, expect high temperatures today in the
mid to upper 80s across the coastal plains and edging into the
low 90s out west.

Long term (Friday through Tuesday)...

although drier air comes down by Friday, pwats Friday are still
around 2 inches over the SE areas and the 850 mb theta-e ridge is
still over the southern coastal counties Friday 18z (and ECMWF is
trying to hold on to rain a bit longer-given it is wet will defer
to it for now). Ergo, did include 20 to 30 pops over the southeast
half of the cwfa. Drier conditions on Friday night and Saturday, as
the upper ridge builds in for a short time. Zonal flow comes into
the area on Sunday, and we could see some isolated showers storms
mainly coastal areas as moisture is sufficient.

By Monday an inverted trough col area approaches develops over the
area and moisture gets even better (especially ECMWF 00z run), so
did go with low chance pops Monday. Better moisture begins to move
out on Tuesday although enough is there to warrant a mention of rain
as the inverted trough is still there so did keep 20 pops in for
most areas (30 pops extreme southern areas).

Temperature-wise, did go a bit cooler than superblend wpcguide
Friday through early next week over most areas for maximum
temperatures (kept the rio grande plains western brush about the
same as not much rain there). That still will result in afternoon
heat indices 105 to 109 (locally higher) Friday through Sunday
mainly over the western portions of south texas. For minimum
temperatures, generally went with a blend of superblend and
wpcguide.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
