Short term tonight through Friday night
The region will be sitting on the western end of the surface high
offshore. Continuous storm systems will stream north into the
lower mississippi valley through the period. This will mean moist
southerly flow across the region with well above normal
temperatures. Currently, shallow CU development area-wide with a
small line of showers moving through the far NW tier. Expect this
precipitation to subside quickly as it moves away from the mid upper
level support. Clouds will erode this evening and calm conditions
will ensue. Some fog and low cloud decks will be possible during the
early morning across portions of central and eastern ga. Any low
level moisture should diminish during the morning hours with the cu
field once again develops by the afternoon. Isolated showers are
possible later Friday afternoon. By Friday evening into the
overnight the surface high retreats farther offshore with the ridge
aloft being undercut by the trough to the west. This will result in
the plume of moisture and associated front sagging toward the region
by early Saturday. Increased precipitation can be expect across
north ga at this time.

Long term Saturday through Thursday
At the onset of the long-term period, the cold front to the west
will begin to finally make some progress into our area, bringing
with it increasing shower and thunderstorm chances. On Saturday the
persistent upper high over the western atlantic will maintain a
decent grip on the area. This will keep the best rain chances across
the northern portions of the CWA on Saturday. By Sunday, the front
will be making headway into the state, and precipitation chances
increase appreciably areawide. With the front entering the state
Sunday morning when instability is relatively meager, this will help
limit severe thunderstorm chances. The best dynamics also will
become displaced from the best instability by Sunday afternoon. The
potential for any stronger thunderstorms will continue to be
monitored through the next couple of days.

After a wet Sunday, there remains some disagreement with how quickly
the front will exit on Monday. The ECMWF is a bit slower than the
gfs and brings a wetter stormier Monday as a wave of low pressure
works its way northeastward along the cold front. Regardless,
both the ECMWF and GFS clear the front east of the area by Monday
night. After the front clears the state, Tuesday will be the lone
dry day. This dry and sunny weather will be short-lived, however,
as the next system will already be entering the area by Wednesday
with rain chances again increasing. Model differences remain with
the evolution of this mid-week system, but the Wednesday into
Thursday timeframe looks unsettled.

Temperatures will be near or above record warm levels again on
Saturday before cooling off slightly Sunday into next week behind
the cold front. Even behind the front, temperatures will remain
above average but not at record-breaking levels.

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.
