short term tonight through Wednesday night ...

the upper level low over the carolina's will begin to lift
northeastward as the surface front continues to push away from
the forecast area. A surface low over the ohio valley will keep
north winds across the area tonight which will allow temperatures
to drop to near freezing across north ga - with below freezing
temperatures across the higher elevations. The models have backed
off a little on the amount of moisture that will move across
forecast area tonight. Short term models continue to show the wrap
around moisture close enough to the forecast area to include
slight to low chance pops overnight into tomorrow morning.

Forecast soundings support a mixture of rain and snow with all
snow across the higher elevations. Any accumulations will remain
light at one inch or less.

Tomorrow surface high pressure will build down the mississippi
valley and models are showing run-to-run consistency as well as
with each other that the surface gradient across the area will be
tight enough for some gusty winds to 35 mph tomorrow afternoon and
have issued a wind advisory from noon to 8 pm. Northwest flow
will keep CAA across the area, even as the skies remain mostly
clear across much of the area. Temperatures will moderate somewhat
with colder than normal temperatures expected.

long term Thursday through Tuesday ...

made some adjustments to the extended forecast trends, especially in
the latter half of the period. Loaded an nbm blend, but did adjust
to back off of the strength of the wedge influence early next week
as there continues to be some divergence between the GFS and ecmwf
through the period. GFS is showing a very strong wedge developing by
Sunday with the new ECMWF a bit slower and not not quite as strong,
at least initially. Consequently, instability is also looking a bit
limited with just enough instability to keep a mention of a slight
chance for thunder for Saturday Saturday night ahead of the wedge
development, but not did not include any mention other periods.

See previous discussion below.

long term Wednesday night through Monday ...

Thursday and Friday will bring moderating temperatures and will
remain primarily dry with only a slight chance of a few showers
sneaking into far north georgia by late Friday. Rain chances
appear to begin to increase more appreciably by Saturday as the upper
pattern transitions into a more zonal flow and a low pressure
system moves into the ohio valley. There is still some
inconsistencies in the run to run guidance of the models but
definitely transitioning into a wetter pattern for the weekend
into the middle of next week.


00z update...

MVFR CIGS will settle in across atl for the evening and into the
early morning hours. Do think some lifting is possible before 12z,
but CIGS should remain bknVFR until after sunrise and until good
mixing gets going. Tomorrow is going to be breezy. Frequent gusts
to 30kt are likely. Gusts should begin to lessen near sunset, but
should continue 20-25kt into the early evening.

Atl confidence... 00z update...

high confidence all elements.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. 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 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.
