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.

Update for 00z aviation cycle.

Aviation
Tonight - Wednesday... MostlyVFR, lower conditions in showers and
storms. Expecting another increase in heavy shower activity later
this evening over most of our terminals. Could be a few periods of
light rain showers after 5am cdt before ramping back up again
towards late morning, all-in-all we continue to have a mess on our
hands. Lower CIGS and vsbys expected in the heaviest showers with
east-southeast winds around 10 knots. Medium confidence in timing.

Previous discussion issued 400 pm cdt Tue jun 19 2018
short term (tonight)...

showers and thunderstorms have been moving across south texas as
the center of circulation progresses inland. Strong low level
moisture convergence and an overly saturated atmosphere (2.51"
pwats on the crp 18z sounding) has contributed to rainfall rates
ranging from 1-3" hr. Jim wells county has seen some of our
highest totals today with rainfall reports ranging from 7-11"
with isolated pockets of larger amounts possible. There have also
been reports of 5-8" across portions of south texas. Reports of
roadways being flooded across the region were fairly common today.

Convective activity has waned a bit this afternoon as some dry air
wrapped around the center of the low. Expect activity to increase
again late tonight into early Wednesday morning, especially along
the coastal bend, victoria crossroads and over the gulf waters as
h85 moisture transports ramps up over the area. Showers and
thunderstorms will begin to redevelop early tomorrow morning,
around 5z or shortly after, per the href which has had a fairly
strong handle on the event.

Temps will be in the mid 70s across the brush country and victoria
crossroads to the low 80s along the coast. Small craft advisory
conditions will continue for the offshore waters overnight with
conditions slowly improving during the morning hours Wednesday.

Long term (Wednesday through Tuesday)...

the tropical wave will continue to move west to southwest on
Wednesday with very deep moisture pwat around 2-2.4 inches
continuing across S tx. This will maintain high pops through wed
with additional rainfall around 4 to 6 inches across the east and 2
to 3 inches across the rio grande plains. The flash flood watch will
remain in effect through Wed afternoon, but may need to be extended
to Wed night or Thu if heavier rainfall continues. The higher rain
chances will shift south and southwest by Thu thu night as drier air
aloft moves in from the NE as ridging begins to build back across s
tx. By fri, limited residual moisture and a weak embedded short wave
may lead to iso convection across the vct area fri, otherwise quiet
weather and warmer temps is expected Fri sat. Another wave is
progged to approach the region by Sunday, bringing another chance of
convection.

Winds across the offshore waters will be borderline SCA Wed morning,
but should be below advisory conditions by noon. Minor tidal
overflow and dangerous rip currents are also expected to continue
into Wed morning, but as winds and seas diminish as well as swell
periods, so will the coastal threats.

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.
