short term tonight through Tuesday night ...

a beautiful fall afternoon across north and central georgia with
just some passing mid and high clouds. Temperatures have warmed
nicely into the 70s and lower 80s. Hope everyone is getting out to
enjoy today because tomorrow will be a different story.

For the first time in a long while, there's a very good chance for
significant widespread rainfall across the area Tuesday into Tuesday
evening. The combination of deep lyr moisture and mid lvl energy
overtop a very pronounced low lvl boundary (sfc-850mb) will support
widespread rain across the area beginning early Tuesday morning, and
lasting throughout the much of the day and into the evening hours
before the bulk of the energy and moisture shifts east of the area.

Questions remain about where the heaviest rainfall will occur, and
this will be largely dependent on the orientation positioning of
that low lvl boundary. At this point, it appears to set up along a
columbus to eastman line across our far southern area with the
heaviest rain likely to occur along and just north of this boundary.

Of course, a slight shift north or south will impact the latest
expected rainfall amounts. Feeling pretty good that a swath of 1 to
2 inches will occur across much of middle ga, mainly along and south
of i-20, with locally higher amounts certainly possible between
columbus and macon where better moisture and forcing will exist.

Thunderstorm potential remains low at this time as best sfc-based
instability and lapse rates remain south of the area, over south al
and ga. That said, cannot rule out a few "elevated" lightning
strikes storms given strong forcing within proximity of low lvl
boundary and upr lvl shortwave energy.

Contributing to the heavy rain potential for Tuesday are very high
precipitable water (pwat) values, expected to be 1.5 to 1.75" around
the ffc atl area (closer to 2" around columbus and macon). These
values would exceed the 90th percentile for oct 15.

long term Wednesday through Monday ...

overall, made minimal changes through the extended forecast as the
medium range models remain in fairly good agreement through the
majority of the period. Cold front exiting the forecast area
Wednesday to start the period ushering in the coolest air so far
this season. Temperatures at or below seasonal normals for the
latter half of the upcoming workweek, moderating back to at or
slightly above normal through the upcoming weekend and into the
beginning of next week. Dry after the system passes on Wednesday
with moisture and precipitation chances creeping back in by the
weekend and increasing into early next week.


00z update...

vfr conditions are expected across the area through the evening,
with mainly mid and high level clouds. During the overnight hours
lower clouds and rain showers will begin to spread over the area
from SW to ne, with MVFR conditions developing over csg between 08-
10z and reaching the metro sites by 15-16z. Heavier, more organized
rain, along with ifr ceilings and visibility restrictions, are
anticipated later in the day, at csg by 13z and spreading to the
metro sites by 17-18z. NW winds of 6 kts or less during the
overnight hours will shift to NE by 05z and E by 11-12z Tuesday,
then increase to 6-8 kts during the afternoon hours.

These have not been checked for accuracy and in many cases have not even been read by anyone associated with I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at 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.
