short term tonight through Sunday night ...

strong frontal system progged to push quickly across the area,
driven by amplifying upper trough currently across the east central
plains and western tn valley. Forecast continues to have a rapidly
progressing line of showers impinging the NW CWA by 7-8 pm this
evening, near the atlanta metro and west central CWA by 9-10 pm then
quickly skirting the remainder of the area by 4-5 am Sunday. Models
continue to have low end elevated instability near 100-200 j kg so
kept slight chance thunder mention. Given the strong shear
parameters and some diffluence aloft aiding the frontogenetic
forcing, cannot rule out a few strong convective cells with enhanced
downdraft winds and a few rumbles of thunder, though greatest chance
of this should be confined to the NW CWA this evening. Enhanced
gradient winds will likely be of more impact with the system as the
low deepens to the north with strong CAA on the heels of the fropa.

Wind advisory continues for north ga through 12z Sunday.

Nw fetch will still be enhanced and gusty through Sunday, though
below advisory levels. While skies will be mostly clear due to quick
ridging subsidence in the wake of the front, highs Sunday should
only make it into the low to mid 50s for most areas given the
aforementioned strong caa. This has warranted a freeze watch Sunday
night into Monday morning for all areas except the southern tier of
central ga. The frost freeze program ends nov. 20, therefore even if
frost or freeze conditions are forecast, agricultural interests will
not warrant watch, warning, or advisory issuances.

long term Monday through Saturday ...

models continue to diverge for the forecast for mid to late next
week. High pressure and mostly fair conditions are expected for
the early part of next week. Temperatures slightly below normal
are anticipated. There is a slight chance for showers across the
southern and east central portion of the cwfa and QPF amounts
remain very light.

The models begin to show some significant differences beginning Wednesday
into Thursday. Both the GFS and the ECMWF have a southward
digging longwave trough and a closed low pressure. The GFS is a
bit faster and further north with the development of the closed
low at 500mb than the ecmwf. The ECMWF develops a closed low at
the surface a little faster than the gfs, but both models show the
best potential for measurable precip remains across the far
southern portion of the cwfa and have upped the pops to around 30%
in the far southern zones.


00z update...

front moving through al and will push into NW ga within the next
few hours. The line of shra tsra will move into the atl area by
03-05z so expecting mainly gusty winds as they move through.

Winds are blowing out of the SW and will turn to the NW after the
line moves through. Wind speeds are in the 08-12kt range but will
increase as the line moves through with speeds reaching the
15-20kt range gusting to 35kt. Ceilings are in the MVFR range and
should stay there until they lift after the frontal passage. Will
seeVFR conditions by 08z-10z with things clearing out by 15z-

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.
