short term today through Tuesday ...
short term forecast largely marked by frontal passage this afternoon
into Tuesday morning. Rapid increase in moisture is still expected,
with shower activity beginning as early as this afternoon. Expect
overcast skies with prominent low level moisture by late morning,
which should act to keep instability limited. Regardless, most
unstable CAPE still looks to be enough to support scattered
thunderstorms, generally just ahead of the front, though best mid
level forcing could pass north of the area in the tn valley. Spc
does have portions of western and central georgia in a marginal risk
for severe storms. Given the front will move into eastern georgia in
the early morning hours, waning instability is not likely to support
any strong activity. Have good chance to categorical pops beginning
18-20z in far northwest georgia, then quickly spreading them south
and east into the overnight period. Moisture quickly exits into
Tuesday, with only slight chance pops in the far southeast corner of
the CWA by 15z mid morning.
Model guidance has been having difficulty with the warm more mild
temperatures over the state over the weekend. As a result, generally
went with an adjusted upward blend of the guidance for highs today
and Tuesday. Precip and cloud cover are still expected to dampen
insolation, but still expect we could be in the mid 60s to low 70s
this afternoon. Highs Tuesday will run 8-10 degrees cooler as a
result of the frontal passage.
long term Tuesday night through Sunday ...
models continue in close agreement with the long term. A
relatively progressive pattern will continue through the long term
with the next short wave moving across the region late Friday and into
the weekend. Guidance continues to give high pops
Saturday Saturday night and this seems reasonable as a wedge sets
up Friday with gulf moisture overrunning the wedge Saturday.
Strong isentropic lift in the lower levels across north georgia
Saturday should produce light rain drizzle ahead of the deepest
moisture which doesn't move into the CWA until late Saturday and
Saturday night. At this time instability will be minimal and
therefore will continue to keep thunder out of the forecast.
The associated cold front will move across the CWA Sunday ending
the precip from the northwest Sunday night. Colder air will spread
across the CWA Sunday night. There will also be some lingering
moisture across extreme north ga Sunday night, and with the colder
air some of the rain could be briefly mixed with light snow or
flurries before ending.
vfr conditions will become MVFR by 15-18z this morning as moisture
moves into the area ahead of a cold front. Expect ifr conditions
by early afternoon. Light rain is expected as early as 18z, but
better coverage thunder expected after 22-23z and kahn and
southern TAF sites could see activity through 06z.VFR conditions
are expected by 12z Tuesday. Winds will start off SE at 6kt or
less, then shift to the SW and increase to 8-12kt. Expect gusty
winds in near thunderstorms.

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.
