00z aviation forecast discussion...

short term tonight through Sunday night ...

to begin the short-term period, a weak frontal boundary remains
positioned across far northern georgia. Surface high pressure
pushing eastward towards northern maine is giving this front a
southward push, setting up a wedge front over northeastern georgia.

The boundary is interacting with deep atmospheric moisture over the
forecast area as it moves southward to quickly generate convection.

Scattered showers and thunderstorms are ongoing across portions of
north and central georgia, and are expected to become more
widespread in the mid to late afternoon hours. Given abundant
moisture, with precipitable water values in excess of 2 inches,
stronger storms that occur could produce heavy downpours which could
lead to localized flash flooding concerns. Moreover, with sbcape
values around 3000 j kg and dcape values of 500-800 j kg, along with
the potential for heavy precip-loading, there is a chance that
several thunderstorms could become strong to severe this afternoon
and evening. Damaging wind gusts will be the primary hazard with any
severe thunderstorms that occur.

With deep moisture remaining in place, it is likely that some
convection will linger into the overnight hours. The wedge front
will continue to make steady progress to the south and west tonight,
allowing cool easterly surface flow to set up behind the front. On
Sunday, the boundary is expected to reach west-central georgia,
allowing for a cooler and more stable airmass to set up over the
majority of the forecast area. Thus, the highest precipitation
chances on Sunday will be concentrated along the western and
southern portions of the area. However, some scattered activity
within the wedge is not out of the question. The cool, low-level
easterly flow building into the area tonight and Sunday will bring
about a noticeable and welcome temperature change through the
remainder of the period. In stark contrast to the mainly above-
average temperatures throughout most of the month of august, high
temperatures on Sunday are anticipated to be as much as 10 degrees
cooler than climatological normals, with upper 70s in north georgia
and low to mid 80s in central georgia.

long term Monday through Saturday ...

mid level ridging gets shoved offshore by Monday as a long wave
trough moves slowly east across the SE us. The trough looks to begin
moving through the CWA later Tuesday into Wednesday... And remains
across the SE us through most of the week and even gets reinforced
during the late week.

At the surface, the wedge should continue to hold strong until later
Tuesday early Wednesday as a weak frontal boundary mid level trough
begins to push through the area. High pressure builds in behind the
frontal boundary through the end of the week into the early part of
the weekend. The first part of the work-week should have the best
chances for precipitation, with the wedge in place and a weak
frontal boundary moving through.

Below normal temps will continue for Monday with the strong wedge in
place. Temps do begin to increase to normal or slightly above normal
for this time of year Tuesday through the end of the week as the
wedge gets wiped out and high pressure builds in behind the fropa.

00z update...

MVFR ceilings spreading southwest across the forecast area at this
time. Should see MVFR conditions at the atlanta metro area TAF sites
by 01-03z and into kmcn kcsg 05-07z. Ceilings will continue lowering
with ifr or lower expected most areas by 06-09z, continuing through
16-18z before some improvement back into the MVFR range. Isolated to
scattered showers and a few thunderstorms will diminish through the
overnight hours, becoming scattered again across the area by 16-18z
tomorrow. Winds will be easterly, generally 6-12kt.

Atl confidence... 00z update...

high confidence for winds, medium on all other elements.

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.
