Version 3.4
What's New / NOTES
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 evening discussion.

Adjusted rain chances for tonight as guidance continues to
indicate that most of the region will be dry. Some showers will
continue through the night near the stalled front and also moving
north from louisiana. In addition, guidance continues to indicate
the potential for patchy fog, some of which could be dense, late
tonight closer to daybreak Tuesday. This would be especially the
case in the northern part of the forecast area and in the delta.

Have added this to the forecast and also will put out a limited
fog threat in the hwo and graphics. 28
prior discussion below:
isolated showers and storms continue this evening with
temperatures mainly in the low 70s. Lows overnight look to be in
the mid to upper 60s. With more moisture expected to advect
back into the area tonight, will not make any changes to the
current rain chances for tonight. 27
prior discussion below:
this afternoon tonight through Tuesday:
the complex weather pattern continues today as widespread clouds
from the MCS over the gulf coast and stream of moisture continues to
keep temperatures down into the upper 70s to just lower 80s. With
the previously mentioned meso-high still over the area and drier pws,
we are definitely on track for another dry afternoon, for the most
part. The cold front is analyzed up in the arklamiss delta, with
better moisture and isentropic lift continuing over the region. Many
mesoscale features of the mcvs, gravity waves and some differential
heating boundaries, will play into this complex mesoscale setup.

Some cumulus fields are developing along the cold front in the delta
and differential heating boundaries along the edge of the cloud
fields. Left chances for scattered showers and storms in there this
afternoon due to this but this is definitely a lower confidence
forecast. In addition a very strong MCS over the gulf is likely
robbing better moisture transport convergence into our area, keeping
it even more uncertain for convection. Due to this and very little
destabilization or convection developing, dropped the marginal for
today altogether for the entire area. If any convection develops, it
will be likely be late enough to limit much if any way of
strong severe potential. These clouds will continue to limit high
temperatures today and adjusted the hourly temperatures and high
temperature today to this current trend.

More moisture will advect back in tonight due to the previously
mentioned shortwave and disturbance over the gulf. Guidance
indicates a MCV mesolow will slowly move northeast tonight but then
the upper forcing will gradually pull away and closer towards our
area into tonight. This will help bring some rain and storm chances
back in later tonight. Maintained rain chances through tonight as
there is too much uncertainty to cut much if any chances. This and
widespread clouds will keep temperatures in the mid-upper 60s. As
the shortwave continues to lift northeast and the forcing pulls away
to the east, expect the best chances for convection Tuesday to
remain mainly along and southeast of the front, with the best
chances southeast of the natchez trace corridor. Hi-res guidance
depicts the more widespread nature of convection tomorrow afternoon
across central and southern-eastern zones. Due to the scattered to
widespread nature of convection on Tuesday, this could keep
temperatures down. They will be into the upper 70s to low 80s in
this corridor southeast of the natchez trace, while areas to the
northwest along the cold front lingering in the area will warm up
into the low-mid 80s. The widespread nature of convection will also
limit strong-severe potential. This will keep lapse rates lower and
wind fields will be weak overall. Dc
Tuesday night through the coming weekend:
the weather pattern still looks quite wet through the extended
period with temperatures remaining at least a little below average
on most days.

Upper level energy gradually pulling away from the region in the
previously-outlined short term period will be replaced by more
incoming (and slow-moving) upper level trough energy Thursday.

This trough will probably wait until sometime early next week to
pass entirely through the region so daily rainfall chances will be
enhanced as at least modest warmth and moisture advection continues
north off the gulf of mexico. There may be enough forcing at
times to throw askew normal early summer diurnal trends in
precipitation but in general anticipate best shower and storm
chances to be in the afternoon through early evening (coinciding
with typical best time windows for available instability). Overall
severe weather chances late this week and through the weekend do
not look too great at this juncture as only non-impressive lapse
rates and wind shear combine on most days. Owing to this
assessment the hwo will be kept clear of convective threats at
this time but we will still keep a close eye on the situation over
the next several days (because it certainly does not take much
wind shear in june around this region to sometimes generate
localized pockets of severe weather).

Additionally, we will have to be watching out for any areas of
locally heavy rain through the week and it is possible as we go
forward we might need to start highlighting areas of greater flood
potential due to repeated downpours. However, at this point the
synoptic setup offered by model consensus suggests the potential
for torrential training downpours is not great and we also must
consider that going into the start of june the lush vegetation
will work to soak up a lot of potential run-off water very
quickly and efficiently. Bb

00z TAF discussion:
taf sites areVFR today with little in the way of clouds. A few
showers or storms are moving into the area but these should be
limited to southern areas through the evening. After midnight,
showers may affect TAF sites along and south of i-20 through the
night. MVFR ceilings may develop either in the shower activity or
near the approaching cold front overnight before improving back to
vfr tomorrow. 28

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 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.
