has been another active evening across the forecast area as
another area of frontogentic forcing and strong isentropic lift
allowed for banded convection at times. In addition, with such low
freezing levels, was not difficult at all to get hail with the
convection, the latest case being the cluster that move through
dade county. Things have settled down now and expect a quieter
night with rain still around but forcing less. Temps now safely
above freezing across the NE mountains but not by much. Models
agree in keeping outside any freezing rain thresholds overnight
but will certainly bear watching. Went ahead and edited pops for
the Wed timeframe keeping lower pops for all but the far northern
sections until prefrontal activity moves in toward evening.

afternoon forecast package...
short term tonight through Wednesday night ...
showers and isolated thunderstorms mainly across north and portions
of central ga as good east to southeasterly flow continues across the
area. The increased easterly flow is helping to push the high
pressure wedge down into our area as the axis of highest QPF looks
to stay north and west of our area. With rain expected to continue
into the extended periods we are still looking for some flooding
across N ga with 6 day totals in the 3-6 inch range. Have added a
few more counties into the current flood watch and will keep it
going through Saturday morning. The watch extends from haralson... To
cherokee... To white counties and all areas north of that line. Winds
will be elevated and gusty at times tonight and Wednesday with some
places at the higher elevations gusting to around 30kts.
Temperatures... Especially under the wedge will stay a bit cool with
lows tonight in the 30s and highs in the 40s wed. Locations not
under the influence of the wedge will see temps get up into the 60s
and 70s Wednesday which will be mainly across central portions of
long term Thursday through Tuesday ...
overall, only minimal changes to the extended period. The only
addition is another wedge front system that will move into the
area Friday night into Saturday as a strong new england surface
high pressure quickly moves off into the atlantic. This extra lift
could further enhance rainfall totals for north georgia during
that time frame. Otherwise, the preceding discussion follows.
Following this continuous bout of rain through Sunday, the next
wave looks just as strong and begins to move into the area on
Monday. A fairly active pattern looks likely afterwards with low
pressure waves causing trouble in the forecast area every few

long term Wednesday night through Monday ...
the long term period picks up with another period of possible heavy
rainfall late Wednesday as the wedge breaks down and a cold front
pushes towards the area. Current models don't show the front making
much progress into the area before becoming more parallel to the
flow and stalling. With the front stalled somewhere in the
vicinity, likely to categorical pops have been included for
northern georgia through Saturday as multiple waves of
precipitation move through the area. With instability present,
thunder has also been included for multiple days of the forecast.|
Also, with such high pw values forecast Wednesday through the
rest of the long term, heavy rain is expected at times over
multiple days continuing concerns for flash flooding and river
flooding. Portions of northwestern ga already has a few rivers in
flood. The flood watch is still in effect for portions of
northeast georgia through early [Saturday]. Make sure to stay
updated to the forecast for any changes to the watch.
The next more organized system looks to impact the area late
Saturday into Sunday as a surface low develops across the midwest
and pushes a cold front into the state on Sunday. With good
instability across central georgia and high pw values, this system
will bring another round of heavy rain and thunderstorms to the
Overall, with the bulk of the precipitation expected to fall in
the short term, current QPF totals from Thursday through Sunday is
about 1 to 3+ inches with the highest amounts across northern
georgia. For more information on the excessive rainfall refer to
the latest esf. Temperatures through the extended are mostly above
average, with highs generally in the 60s and 70s with lows in the
40s to lower 60s. Some areas are even pushing low 80s across
central georgia through the weekend.
a mix of ifr lifr CIGS will continue through the forecast. Winds
will be easterly and gusty early this morning, diminishing after
12z but remain mainly east through this evening. Winds will become
south to southwest tonight as the warm front lifts north of
atl ahn. Best chances of rain will be north of atl ahn, however as
the cold front approaches tonight, chances of rain will increase.
There is a risk of tsra this afternoon and tonight, however risk
is too low to mention in the taf.

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.
