short term today through Sunday ...

current satellite loop shows moisture plume associated with the old
frontal boundary extending from just off the mid atlantic coast down
the ga coast and across north central fl. This moisture should stay
in place one more day as a much drier air mass across north and
central ga keeps things mostly dry today. Areas south and east of
macon will see some increased moisture today so included a slight
chance of afternoon showers and thunderstorms today. Instability
indices stay fairly low today so any showers and thunderstorms that
develop will stay below severe limits.

Moisture begins to increase across the entire area from the south
and north Sunday which is definitely evident in the precipitable
waters. Pws go from 0.9-1.2 inches today to 1.4-1.5 inches Sunday.

Instabilities also increase with mucapes getting into the 1700 j kg
range. Lifted indices and shear values stay fairly weak so not
looking for much in the way of severe storms but would expect to see
some strong storms Sunday.

Heat index values will get into the 98-102 deg range over much of
central ga on today... But should remain below advisory criteria.

Forecast high temperatures should continue mostly above normal
areawide for today and Sunday.

long term Sunday night through Friday ...

as the extended period begins, broad upper-level ridging will be in
place to the west of the forecast across the central CONUS and to
the east of the area over the western atlantic. A transition in the
pattern will be ongoing by Sunday night as weak troughing will be
building in between the two ridges. This upper-level troughing
will allow for a gradual moistening of the airmass, northward
advection of the deeper moisture, and an overall more unsettled
pattern through the remainder of the period. At the surface, a
dissipating frontal boundary will remain stalled across central
georgia on Sunday night, providing a focus for some lingering
isolated showers and thunderstorms in central georgia.

The persistent trough and increase in deep moisture will allow for
greater coverage of diurnally driven convection during the afternoon
hours each day in the coming week. Primarily chance to low-end
likely pops are expected across the area each afternoon and evening
starting Monday. With precipitable water values approaching 2 inches
by Tuesday, there is a possibility that some of the stronger
thunderstorms could produce locally heavy rainfall each day. Late in
the period, a deep longwave trough extending from the great lakes
region is anticipated to drop another cold front towards the
forecast area, providing a chance for some more organized
convection. However, model guidance remains inconsistent with the
handling of this feature at this time. The increase in convective
coverage and clouds during the extended period will also somewhat
moderate temperatures. Highs are thus expected to return to near
or just above climatological normals, in the upper 80s to low 90s
each afternoon.

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.
