convective coverage across the area this afternoon into the early
evening than expected, but still have some potential for isolated to
scattered showers and thunderstorms. With the afternoon heating well
past its peak, chances will continue to diminish through the
overnight period. More organized convection to the north has been
diminishing as it moves south, but does merit slightly higher pops
lingering through the early morning hours across the far north.
Otherwise, no significant changes made to the short-term forecast at

Short term tonight through Wednesday night ...
widespread severe weather is not expected today, but marginally
strong to a few severe storms are possible today as diurnally-driven
convection fires. Weak upper level trough remains situated over the
area, and the surface low feature will continue to provide a focus
for storm development. This low will move northeastward over the
carolinas into Wednesday, with drier westerly flow setting up behind
Models continue to show highest storm chances over the southern and
eastern portions of the cwa, with gusty winds and frequent lightning
as main concerns. Additionally, with high precipitable water values,
brief heavy downpours can be expected with the strong or slow-moving
storms, and a quickly accumulating 1-2 inches or more are possible.
Rain chances are not quite as high Wednesday with the absence of
better moisture, but have continued to forecast good chance
thunderstorms for the peak heating period.
High temperatures Wednesday are slightly higher than today, with
most of the area back in the 90s. Heat index values will largely be
under 100, with a few patchy areas just above 100.

afternoon and evening scattered to numerous showers and
thunderstorms will continue through the extended periods of the
forecast. The area will remain situated in the weak upper trough
between the ridge over the plains and western atlantic ridge.
Moisture continues to slowly increase across the area through the
end of the week which will will provide a boost each afternoon for
convective development. By the end of the week, the models are
showing a cold front pushing south out of the great lake state
Thursday and into north ga Friday. The models show this frontal
boundary stalling across the southeastern u.S. And keeping rain
chances across the region through the end of the forecast period.
By Sat Sun a wedge of high pressure builds down the eastern
seaboard and keeps things rainy and cool for this time of year.
Looking at temps in the 70s and 80s across north and central ga.
mainlyVFR conditions are expected across the forecast area
through the period, with the exception of some patchy MVFR
visibility restrictions near mcn csg ahn between 09-14z. Some
scattered low-level clouds at 020-030 are also possible during
that time. Scattered convection is expected once again area- wide
during the afternoon after 18z, with sufficient coverage to
warrant a prob30 for tsra from 19-24z. SW to W winds through the
period will be generally less than 5 kts this morning, then will
increase to 5-10 kts by 18z.

medium confidence on the development of scattered low clouds.
High confidence on all other elements.

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.
