What's New / NOTES
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.

Update
Updated for 00z aviation discussion.

Aviation
00z TAF discussion:
a cluster of thunderstorms is expected to impact khbg between 00z
and 02z, with possible gusty winds and briefly lower visibility as
those storms move through. Otherwise,VFR conditions and light
winds expected to prevail at all TAF sites until around 11z
Monday. Some br development then looks possible, with better
chances for a few hours of MVFR visibility at kglh and khbg before
fog any mixes out. A few showers or thunderstorms cannot be ruled
out near the end of the period, but expected coverage is too low
to include mention in tafs at this time. Nf

Discussion
Expect another muggy night tonight after the evening stray
showers and storms diminish by a few hours after sunset. Lows will
be in the low to mid 70s with only a few patches of light fog
around at daybreak.

Tomorrow, the subtropical ridge aloft over the lower ms valley
will start lessening its grip a bit, but certainly not in a
dramatic way. Convective suppression will not be as much as today
and we should see a little better coverage of afternoon showers
and storms in at least southern and western zones. Of course the
biggest story in the sky tomorrow will be the partial eclipse
overhead starting in the late morning and ending in the mid
afternoon. The partial insolation blockage in our region will
peak shortly after 2 pm and we actually anticipate enough shade to
cause at least a little temperature decrease during the time of
day usually reserved for peak heating. This shade will certainly
be welcome because otherwise the continued hot regime would be
unabated and more heat advisories would likely be necessary.

However, since we are taking the eclipse into account, our current
thoughts are that heat indices will remain too marginal for
another heat advisory (but of course the next shifts will be
examining that aspect of the forecast closely). Also, keep in
mind the shade and somewhat reduced associated instability during
peak heating will probably mean computer models (which don't take
the eclipse into account) will probably overdo afternoon
convection here. That potential bias was kept in mind when doing
the forecast. Bb
Monday night through Saturday: come Monday night the eclipse will be
over but a 594dam ridge axis will continue along the highway 82
corridor while a tutt axis pokes up over our northeast louisiana
parishes from the northern gulf. Both of these features will weaken
Tuesday as mid level troughing develops over the eastern CONUS and
the tutt shifts farther west over the texas coast. Afternoon
temperatures in the low to mid 90s Tuesday will combine with high
relative humidity in our west for peak heat index values to range
from 101-104. A heat advisory is not currently anticipated for
Tuesday but, cooler temperatures and lower relative humidity look to
mitigate heat stress related concerns the remainder of the week.

A closed low swinging across ontario and into quebec Tuesday night
into Wednesday will send a cold front into the region Wednesday.

Although there appears to be very little convergence across our cwa
when the cold front drops in, 2 inch pwats look to pool across our
cwa ahead of it. Lower heights aloft and daytime heating should
contribute to a good coverage of convection Wednesday afternoon into
the early evening hours. By Thursday morning the cold front is
expected to be near our highway 84 corridor with dew points in the
60s north of interstate 20. Continued northwest flow aloft Thursday
will support a >1020mb high dropping over the great lakes region and
nudging the the front south of our cwa. By Friday morning, a much
drier airmass will have filtered into our whole CWA with dewpoints
in the 60s areawide. Although mid level ridging will strengthen over
the region Saturday, the surface high will shift east slowly through
the weekend. This will keep the gulf closed over our area and hold
deep moister at bay while temperatures warm. Cooler than normal
afternoon highs are expected Thursday and Friday; mainly in the
upper 80s. Afternoon highs will top out closer to normal Saturday
and Sunday but due to the drier airmass remaining over the region,
peak heat index values will not reach critical values. 22

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.
