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.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

short term (tonight through Tuesday night): tonight, the arrival
of drier air and thinning high clouds behind a Monday morning
cold front will allow temperatures to cool into the mid 40s to
lower 50s. Slightly cooler weather will continue on Tuesday, with
high temps from the upper 60s to near 70 degrees. Mostly sunny
skies and light northeast winds will prevail. Though surface high
pressure will support northeast low level flow Tuesday night,
moisture just above the boundary layer returning from the south
will surge quickly back into the area, increasing cloud cover and
supporting a chance of rain mainly for sections of the southern
gulf and the southeast corner of the cwa, including cameron and
portions of willacy and hidalgo counties. Rain amounts should be
light, measuring in the hundredths of inches.
Long term (Wednesday through Monday): southwest flow aloft will
continue through the remainder of the week as a trough extends
southward from the four corners region. This will continue to toss
minor impulses across south texas. At the sfc, high pressure to
the north will be moving east, allowing winds to shift back from
the southeast, tapping increasing gulf moisture. This added
moisture and instability aloft will bring a small chance for
showers, for the lower valley into Wednesday morning, and areawide
again Thursday. Accumulations will remain light. The next front
dives into texas Friday, arriving in deep south texas on Saturday.
Instability along and ahead of the front will bring a continued
chance for showers. Drier high pressure will move across the|
region for the latter half of the weekend into early next week,
with an end to any rain chances and high temps back to the 60s.
now through Tuesday night: high pressure will spread over the
gulf, and moderate northeast winds will prevail, supporting
Wednesday through Friday: the high pressure will be moving to the
east across the southeastern us, with winds gradually shifting
from northeast to southeast through the period. Winds will remain
10 to 15 knots through the period, which will continue to push
swells up to near 5 feet across the gulf. Increasing moisture and
passing impulses aloft will help spark a few showers here and
there through the period, but rainfall will be isolated in nature.
Fire weather: depressed relative humidity values, as low as the
teens, will redevelop on Tuesday afternoon, mainly across inland
areas, but winds at 20 feet will be less than 15 mph. Thus, while
critical fire weather parameters likely will not be exceeded, some
erratic wildfire behavior will be possible, including better growth
and spread potential.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. 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.
