short term today through Monday ...

an upper level low pressure system will traverse the region today,
with minimal impact other than increased clouds. At the surface,
high pressure settling over the area will result in
southerly southeasterly flow, which will continue to allow for
warmer temperatures. Highs today are expected to top off in the 60s
to near 70. Lows overnight will only drop into the 40s.

Near the end of the short term, a cold front will approach the state
Monday evening, and have continued likely pops and slight chance of
thunder through the remainder of the period. Temperatures will
remain the 60s to low 70s Monday, and instability should be enough
to support isolated thunderstorms. At this time, models are only
indicating a few hundred CAPE as the front moves into the state
Monday evening, with instability dropping off into the overnight
period.

long term Monday night through Saturday ...

models continue in pretty good general agreement through the short
term with some minor timing differences in next weekends system.

Early in the long term, a cold front will move across the cwa
Monday night. Areas of showers and isolated thunderstorms will
continue ahead of the front with the better chances across north
georgia where the deeper moisture will be. By Tuesday morning the
cold front will be in the carolinas with drier air spread across
the cwa. This dry air will continue across the CWA through
Friday. An h5 ridge will build over the eastern u.S. During the
latter half of the upcoming week, and by Saturday this ridge will
be to our east with southwest flow over the CWA by Friday night
and Saturday. At the surface the strong high pressure will be
ridging into the CWA Friday and Saturday with a cool easterly
flow. Another storm system will be developing over the midwest and
lower mississippi valley and this will spread moisture into the
cwa Friday night into Saturday. This will create an overrunning
situation with mainly light rain drizzle developing Friday night
and Saturday over mainly north georgia. Temperatures through the
long term will be near normal.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
