short term tonight through Tuesday night ...

models in good agreement for the short term. H5 ridge builds through
the short term which will suppress any convection but at least allow
for a CU field to develop Tuesday. At the surface a ridge of high
pressure will build into the CWA tonight, briefly shifting the winds
to the northeast, but this will be short lived as the surface high
moves off the atlantic coast and a winds shift back to the southwest
by Tuesday afternoon. Temperatures will remain above normal. Tuesday
highs will be nearly 10 degrees above normal at most locations
across the cwa.

On a personal note, this will be the last afd I will write for the
national weather service. After 33 1 2 years of working for the
national weather service I am retiring. It has been a pleasure
and honor serving the people of youngstown, oh, bismarck, nd and,
for the last 25 years, the people of north and central georgia. I
will always have fond memories of the NWS and the people that i
have worked with. God bless!

long term Wednesday through Monday ...

ugh! For anyone complaining about the cold temps 3 months
ago... The upcoming heat wave is your fault.

Unanimous agreement in the models over ridging that develops
through the week as a deep trough entrenches itself across the
western us into the foreseeable future. GFS and ECMWF agreeing on
both the placement and intensity of the center of the 500mb and
700mb ridge over central and western ga by Thursday afternoon.

Forecast 500mb heights of 595dm over csg and 594dm over atl on
Thursday would be all time may high heights per SPC sounding
climatology as well... By a long shot. By Saturday, 500mb ridge
starts to flatten and shift slightly south however... Forecasts of
the 700mb ridge peak by Saturday which spells greater thermal
capping through the weekend. Air quality issues will likely become
more of an issue through the weekend as a result.

Low end tstorm chances on Wed and thur across north and northeast
ga where the mountains may act as an elevated heat source for
storm initiation... But expect those chances to decline into the
weekend as the 700mb ridge strengthens and maximizes the cap.

Not only will daily records be in jeopardy starting Friday through
Monday, but all time may highs are also either currently forecast
or will come close.

For reference, the all-time may record highs are as follows:
atlanta - 97 degrees f in 1914 and 1941
athens - 100 degrees f in 1918 and 1926
columbus - 100 degrees f in 1916 and 1937
macon - 99 degrees f in 1898, 1953, and 1967

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.
