00z aviation discussion.

Short term
Fair skies prevail across much of central with surface high
pressure over the mid atlantic region. Surface southeast winds are
increasing the dew points gradually and will support an increase
in clouds late this afternoon and into the evening hours.

Continued to maintain slightly lower pop's across central alabama
through late afternoon followed by few changes to the ongoing
forecast tonight and into early on Wednesday. Expect rain chances
to increase overnight and into early Wednesday as a weak front
along the gulf coast lifts northward toward central alabama.

previous mesoscale discussion from this morning.

12z balloon sounding revels a relatively dry profile with a stout
subsidence inversion around 700 millibars. Additionally, a
radiation inversion was detected right off the surface. The
radiation inversion has mostly already mixed out with surface
temperatures already in the lower 70's at 8 am. Precipitable
water values are around 0.93 inches which is about a tenth of an
inch less than this time yesterday morning. The wind profile
overall is weak with southwest flow aloft while a more southerly
flow was present toward the surface.

Morning surface analysis along with recent radar and satellite
imagery review indicates lower pressures that exist along the
central gulf coast while higher pressures were found across
north-central georgia. Two low-level boundaries were found in
satellite imagery over interior southwest alabama and were
drifting northeast.

Due to the drier air in the sounding this morning opted to
slightly decrease pop's across our north-central counties while
slightly increasing pop's late this morning through the afternoon
over our southern and southeast counties. The two low-level
boundaries may help to enhance surface convergence across our
southern and southeast counties late this morning and into early

previous short-term discussion:today and tonight.

Overall high pressure will still be in control of the region today
and tonight. However, we will see some more features that will
impact the region and begin to moisten up the area for the
extended portion of the forecast. For this afternoon, we will
begin to see a seabreeze move northward. Looks like it will
approach the area late in the afternoon into the evening hours.

Will include isolated to scattered showers and storms in the far
south through this evening. We will continue to moisten as
southerly flow increases over the region. There may be just enough
lift late tonight to generate an isolated shower storm across the
eastern two-thirds of the area so will include during that time
as well. Most of the area will remain dry through the next 24
hours. More of a typical summer time forecast, with a little more
in humidity by the afternoon.


Long term
Thursday through Tuesday.

Deep moisture will continue to spread inland on Thursday as a
disturbance moves northward from the gulf of mexico. For the
weekend, an upper-level trough is expected to approach the region
and provide additional focus for convection. This pattern should
lead to an extended period high rain chances for Thursday through
Sunday. Rain chances may decrease somewhat for early next week with
the passage of a diffuse front, but moisture content could remain
sufficient for isolated diurnally-driven convection.

00z TAF discussion.

A cluster of storms and showers continues to push northward across
west central alabama this evening, and have included tsra at tcl and
shra eet to begin the TAF period. Scattered storms are developing in
southwest georgia, and will need to watch that development as it
progresses northwestward. It could impact toi and mgm later tonight.

Clouds will increase early Thursday morning, with MVFR cigs
expected. Showers and storms are also expected, with uncertainty
regarding timing and coverage through out the day tomorrow. Hi-res
guidance shows clusters of storms developing as early as pre-dawn
and continuing through the day. Will make refinements as confidence
increases. Also, guidance brings in MVFR ifr CIGS overnight, and
might need to include lower CIGS earlier than currently forecasted
with the next forecast package.


Fire weather
Rain chances should begin to increase across our southern areas
today. This will continue for Thursday through Sunday with high
rain chances expected. There are no fire weather concerns.

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 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.
