Short term today through Sunday
The main concern for today continues to be the persistent upper
ridge and hot temperatures. Little in the way of dynamics to force
convection... But old boundaries from Friday and afternoon heating
should be able to trigger a few showers and thunderstorms. Have
broad brushed 25 to 30 percent pops for the afternoon. Thunderstorms
should diminish by 06z and Sunday looks like it will be a repeat.

Afternoon temperatures should range in the low to mid 90s for much
of the forecast area today. Dew points were tweaked up again for
today to go with persistence. Current heat advisory looks good
except have added another row of counties on the northern side
since these areas were showing hi values of above 105. Models
indicate somewhat lower thickness values for Sunday... However still
looking for only a slight difference in MAX temperatures.

Long term Sunday night through Friday
The forecast through the extended continues to be characterized by
daily shower and thunderstorm opportunities. At the onset of the
period on Monday, an upper shortwave and approaching cold front will
serve to focus scattered convection, especially by afternoon and
evening during peak daytime heating. Given a moisture rich airmass
with pwats around 2 inches, locally heavy rainfall can be expected.

Furthermore, as is typical during mid summer with building afternoon
instability, some strong thunderstorms will be possible.

This weakening cold front will continue to linger in the
area through midweek, which will enhance diurnal convection each
day. By late week, the upper levels transition into a northwest flow
pattern. Any disturbances riding into the area will bring additional
shower and thunderstorm chances to the state with the increased
potential for mesoscale convective systems arriving from the
northwest.

High temperatures will not stray too far from normal through the
long-term period, with highs generally near 90 in north georgia and
into the lower 90s in central georgia. Low temperatures, meanwhile,
will run a few degrees above normal in the mid-70s with the
exception of cooler temperatures in the mountains.

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.
