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.

Surface high pressure building into our area will bring nly winds of
10 to 20 kts at kaus and 8 to 14 kts at ksat kssf while only around
5 kts at kdrt due to a lighter pressure gradient there overnight to
around midday into early afternoon on Tuesday. High pressure begins
to move off to the east Tuesday afternoon with winds decreasing and
becoming nely around 5 kts at kaus, ksat, kssf and sely at kdrt
Tuesday night.VFR skies will prevail with few-sct cirrus overnight
through Tuesday night.

red flag warning expired.
winds have weakened below critical thresholds across the region and
we have allowed the red flag warning to expire. Relative humidity
will increase as the temperatures drop through the evening rising
above critical levels within the next few hours. We expect near
critical conditions again Tuesday afternoon, but winds should remain
below critical criteria.

00z aviation forecast below.
vfr conditions through the TAF period with periods of high cirrus
this evening. NW winds will continue to diminish early this evening
to around 6-11 kts after sunset and becoming more n. Winds at sat
and aus will increase slightly Tuesday after 15z from the N with
some occasional winds gusts between 15z-21z between 15-20 kts.

short term (tonight through Tuesday night)...
critical fire weather conditions ongoing this afternoon...
main hazard highlight remains the well advertised and ongoing
critical fire weather conditions due very low humidity values ranging
from the single digits to teens and sustained winds in the 10 to 20
mph range along with 25 to 35 mph gusts. Combined with dry
vegetation from the moderate drought conditions all parameters
included will aid in increased risk of rapid fire spread, if one was
too occur. A red flag warning is in effect until 7pm this evening for
much of the area. Winds will decrease through the evening with
humidity increasing with conditions improving.
Temperatures have reached into the upper 70s to the low 80s while|
dewpoints have dropped into the teens and low 20s behind a frontal
passage that occurred this morning. Higher dewpoints will shift into
the region overnight as another weak boundary moves south. Near-
critical fire weather conditions are expected again tomorrow but
winds will be lighter and humidity will be higher. Still, any type of
burning is discouraged. A ridge of high pressure will shift over
north-central texas and aid in the lighter winds along with cooler
Long term (Wednesday through Monday)...
near to above normal temperatures expected through the entire period
with dry conditions set till at least Friday. Low-end rain chances
will be possible Saturday but light accumulations are expected. Next
better chance of rain and unsettled weather will be next Monday and
Tuesday with a more active southwest flow pattern coupled with a
possible frontal zone nearby.
Mid-level northwest flow will persist through much of the work week
as a deeper trough forms over the eastern CONUS and a dampened ridge
develops over the across the southwest u.S. The surface ridge of high
pressure will shift east by late week acting to open up the gulf
moisture fetch back into texas. Low clouds and some fog will be
possible by late week and into the weekend. By Saturday and Sunday,
southwest mid-level flow will be reestablished as weak shortwave
trough shifts over the southwest conus. A few migratory embedded
impulses could help some showers over the weekend but overall
accumulations look light currently. Strong surface cyclogenesis is
agreed upon by mid-range global models across the central plains
this upcoming weekend and an attendant cold front looks to shift
south towards the region by early Monday. If the front is able to
reach the area and coupled with implied impulses shifting across in
the mid-level flow, a few rounds of showers and thunderstorms could
be possible Monday and Tuesday. Furthermore, a deeper shortwave
trough may be in position by Tuesday near big bend area for further
dynamic lift support. Needless to say, early next week looks to be
the best rain chance to help with the current drought conditions.

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.
