Short term tonight through Sunday night
A convergence zone seen on Sat pics is the main area of convection
this afternoon. There could be a southward drift to this but for the
most part it will remain across north georgia where scattered tsra
will continue this afternoon into the evening. Across central ga
forcing mainly driven by daytime heating will be more isolated to
scattered and should dissipate quickly this evening. A surface
trough will become a little more defined Sunday as deeper gulf
moisture spreads into the cwa. Pws push into the 1.5 to 2.0 inch
range. Have gone with high chance pops closer to the surface trough
across north georgia Sunday afternoon and low chance pops central.

Temperatures will be a few degrees cooler across the CWA Sunday.

Although heat index values will reach into the 100 to 104 range,
values should stay below 105 keeping the CWA out of heat advisory
criteria for Monday.

Long term Monday through Saturday
Minor adjustments to raise some late week pops in the northern
portion given more consistency on some NW flow influence before
some late period ridging can possibly finally make it into the
area. Refreshed other fcst elements with latest blend, which has
not differed much from before. Previous discussion follows...

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.
