short term today through Thursday ...
weak upper level troughing remains situated over the area to begin
the short term period, keeping the forecast area in a relatively
moist and unsettled pattern, favorable for unorganized, diurnally
driven thunderstorms each day. At the surface, a weak area of low
pressure is moving northeastward into the carolinas and will
continue through the remainder of the day Wednesday. Westerly low-
level flow has set up behind this feature, which is expected to
bring in some relatively drier conditions today and tonight. The
absence of better atmospheric moisture will lead to reduced rain
chances on Wednesday in comparison to the previous couple of
days, with chance pops across the area. During the peak heating
period, the highest chances will be across north georgia at 40-50
percent, with the lowest chances across central georgia at 25-35
percent. A return to more southerly low-level flow and increasing
deep moisture on Thursday will allow for greater coverage of
diurnally-driven convection in the afternoon and evening, with
high-end chance pops across much of the forecast area in addition
to likely pops across far north georgia.
While widespread severe weather is not anticipated this afternoon
and evening, a few strong to marginally severe thunderstorms are
nonetheless possible. Gusty winds are the primary threat with any
strong to severe storms that occur, with frequent lightning and
brief heavy downpours as additional hazards. High temperatures on
Wednesday and Thursday will be roughly 3-5 degrees higher than
climatological normals, with most of the forecast area in the low
90s. Heat index values will largely remain under 100, and well
outside of heat advisory criteria, although a few patchy areas may
exceed 100 each afternoon.
long term Thursday night through Tuesday ...
a moist and unstable air mass will continue under the flat ridge
aloft. However... A broad trough moving across the great lakes this
weekend should push a frontal boundary into ga. This front looks
like it will stall in the vicinity of central ga on Saturday with
a wedge building into north ga. This configuration should keep|
chance to likely showers and thunderstorms across the area. By the
first of next week... An upper level trough moves across the oh and
tn valley region keeping north and central ga in an unstable
environment. High temperatures should moderate mostly into the 80s
by the weekend and into next week.
ifr lifr ceilings are building in over the metro TAF sites to
begin the TAF period, and conditions are expected to improve by
14-15z. AVFR CU field at 035-050 then develops and will remain
through the afternoon hours. Scattered tsra is expected area-wide
during the afternoon, with the highest chances across north
georgia. Convection is expected to peak later in the afternoon, so
the prob30 at the metro sites and ahn has been pushed back to
start at 21-22z. With lower chances at csg mcn, only vcsh has been
maintained at these sites. SW winds at mainly less than 5 kts
this morning will shift to W this afternoon at 5-10 kts before
weakening and shifting back to SW overnight.

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.
