Marine Weather and Tides
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.
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.

Aviation 00z tafs
strong onshore flow this afternoon has continued to feed moisture
into the region. CurrentVFR conditions will fall back to MVFR
around 05z-07z then ifr 10z-12z. CIGS will be slow to lift Saturday
and do not expect a return toVFR until 18z west and 22z east. Gusty
s SE winds through at least 03z will decrease to near 10 knots
overnight. At this time looks like the winds speeds will be less on
Saturday. S SE winds after 15z-16z should remain near 10 knots. Could
see a few sprinkles Saturday morning, but confidence is not great
and will not include in the forecast.

short term (tonight through Saturday night)...
low level moisture will steadily increase tonight through Saturday
night beneath a capping inversion. This will lead to increasing
cloud cover and warmer overnight lows. Can't rule out some patchy
drizzle or light rain Saturday morning along the southern escarpment.
Winds on Saturday should be weaker than today as the pressure
gradient relaxes slightly.
Long term (Sunday through Friday)...
a strong capping inversion will remain in place Sunday and Monday
across central and eastern areas of the CWA with continued warm and
mostly cloudy conditions as well as a slight chance of showers.
Farther west, the dry line Sunday afternoon and evening should become
active across west central texas along with a few storms associated
with orographic lift up the serranias del burro. Can't rule out some
of these storms making into far northern and far western areas of the
cwa late Sunday where cap erodes. CAPE values are forecast to
increase to over 1500 j kg along with deep layer shear values of 60
kts, and can't rule out a storm or two becoming strong to severe,
with hail and damaging straight-line winds the primary threat. The
day 3 marginal risk from SPC clips far northwest areas of the cwa. A
mid level shortwave in the southwest flow aloft will aid in convection
chances Monday night into Tuesday and send the dry line further into
the southern edwards plateau and rio grande plains Monday afternoon
and evening and into the hill country Tuesday. This should allow for
better chances for showers and storms near and northwest of a del rio|
to llano line late Monday as the cap erodes. Again instability and
shear values should be favorable for some strong to severe storms
northwest of this line and eventually extending eastward through
portions of the eastern hill country Tuesday.
Better chances for more widespread rainfall will come Tuesday night
through Wednesday night as a combination of a potent upper level low
to the west across northern mexico opens and approaches, interacting
with a frontal boundary and deep moisture in place. There is still
significant uncertainty on frontal timing between GFS and ECMWF on
Wednesday as well as run to run consistency. 12z GFS is now quicker
and farther south with the front Wednesday with post frontal
precipitation and cool temperatures over the region. However it does
appear showers and storms will be likely in general Tuesday night
through Wednesday night, possibly with more of a focus for pockets of
locally heavy rainfall if all ingredients come together, especially
with a slower frontal solution and the significantly anomalous high
precipitable waters forecast over the region.
Drier conditions and clearing skies are expected Thursday as the main
trough axis moves east. An upstream disturbance aloft is shown by
the GFS to move through west central texas and into north central
texas Thursday night into Friday, possibly clipping northern areas
of the cwa. ECMWF has this signal as well, but slightly faster. At
this time will keep the Thursday night and Friday dry due to

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
