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.

Updated for 00z aviation discussion

Aviation
00z TAF discussion:
convection is diminishing early this evening and this will be
followed byVFR conditions in the generally dry airmass for most
of the forecast period. Anticipate east to southeast winds through
the next 24 hours at 10 mph or less with any potential for late
night to early morning sub-vfr conditions mainly confined to
pib hbg. Bb ec

Discussion
Through Monday afternoon:
short range explicit convective allowing models have been having a
tough time keeping up with convection the last few afternoons,
typically underdoing rain chances. Such is the case this afternoon
and there are currently a good deal of small showers and embedded
thunderstorms across the region. This activity is drifting
westward with low to mid level flow while pseudo-seabreeze earlier
has instigated a more solid band of thunderstorms in southern
zones, now progressing through the pine belt. Decent instability
(sbcape values from 2000 to 3000 j kg) and dry air aloft yielding
downdraft capes in some cases in excess of 1000 j kg should allow
at least a few storms to produce gusty winds through early evening
(when convection should be rapidly diminishing). We will continue
to advertised the marginal risk of severe storms in the hwo for
areas south of i-20 through early this evening.

Otherwise for tonight, expect clear to partly cloudy skies and
little precip by late evening with decent radiational cooling
conditions and scattered ground moisture allowing for a bit of
patchy fog come daybreak, especially south of i-20. Currently, the
potential for dense fog is not at all great and therefore the
hwo graphics will be kept clear of any mention of a fog hazard.

Lows will be a little above normal, but still not terribly bad for
late september (mid to upper 60s).

Tomorrow, the upper low overhead will be weakening filling quite
rapidly and will not have the same cold pocket aloft to aid in
destabilization. There still will be enough instability and
moisture to give rise to isolated afternoon showers and storms
(with the best coverage probably again in southern zones). The
potential for any severe storms tomorrow should be less owing to
lesser overall amounts of instability. Temperatures will continue
to be a little above average, ranging from 86 to 91 degrees. Bb
Monday night into next weekend...

the current weather pattern will modify slightly early in this
period and more significantly late in the period. The above normal
temperatures will remain through most of the week and the diurnal
rain storm chances will begin to decrease by Wednesday. The upper
level low centered over the region will begin to weaken and push to
the SE on Tuesday. Although coverage is expected to be less than
previous days, some diurnal type thunderstorms will be possible on
Tuesday with better chances south of i-20. Upper level heights will
begin to increase late Tuesday into Wednesday resulting in a ridge
building over the region. This should help to keep the region mostly
free of storms on Wednesday. A dry front will begin to sweep through
the region on Thursday but not before temperatures increase to well
above their late september averages.

Slightly cooler, drier air will begin to filter into the region
behind the front. A reinforcing front will push through the region
on Friday. A more noticeable change will be present after the
second frontal passage pulls in a cooler, drier continental
airmass over the region. Highs will remain in the low 80s
throughout the weekend. There are no chances of precip in the
package worth noting after Tuesday.

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.
