Update
Made a few adjustments to the short term forecast grids, mainly to
the hourly temperature, dew point and sky cover grids to fit current
trends. Nothing that will fundamentally change the nature of the of
the current forecast as general, overall, forecast remains on track.

short term tonight through Monday night ...

while the upper low has exited well to the northeast, lingering low
level moisture has kept pesky low clouds in place across most of the
area this afternoon. These low clouds are expected to gradually
break and lift by late evening with widespread clearing finally
taking hold overnight.

Monday will be the first dry and sunny day in quite a while as high
pressure continues to build into the southeast. Under abundant
sunshine, high temperatures will rebound to around five degrees
above normal areawide, ranging from the upper 50s in north georgia
to the mid 60s in central georgia. With continued clear skies, low
temperatures will drop to near normal by Tuesday morning with lows
in the 30s.

long term Tuesday through Sunday ...

still some slight timing amplitude differences with broad trough
and associated frontal system for thurs fri. Limited some of the
slight thunder mention a bit farther south for Thursday and still
have mention of rain or snow shower mix in the far north on the
heels of the wrap-around for late Friday. Will need to keep
monitoring especially the NE mountains for such transition
potential. Previous discussion follows.

long term Monday night through Saturday ...

models continue to come together on the system moving across the
cwa at the latter half of the upcoming week. The long term begins
with dry high pressure, but as a upper trough over the west coast
moves into the southern plains it will strengthen. This will pull
gulf moisture into the CWA beginning Wednesday night and
continuing into Friday. The system will deepen to a closed low,
however location is a bit different between the GFS and ecmwf. The
resultant weather, however, will not be much different... And with
consistency in the models from run to run, have increased pops
Wednesday night through Friday night. Models also increase
instability Thursday and have continued with the mention of a
slight chance of thunderstorms for Thursday. Another issue will be
a rain snow mix Friday night across the mountains. By this time,
however, the system is pulling out and the chances of
precipitation are decreasing.

northwest 7-12kts before diminishing to 5-9kts by 06z.

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.
