What's New / NOTES
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

Update
Diminishing batch of convection across north northwest ga this
evening is holding on a bit longer than expected. I have adjusted
pops a bit to reflect this and reworked hourly temperatures and dew
points to better depict the rain-cooled airmass across much of the
forecast area. No changes made beyond the overnight hours at this
time.

short term tonight through Tuesday night ...

A severe thunderstorm watch is in effect for portions of north
and central georgia until 9 pm edt...

as expected, with ample instability in place, thunderstorms are
quickly developing, primarily in association with an impulse moving
from eastern alabama into western georgia. Thunderstorm coverage
will continue to increase, especially ahead of this disturbance as
it traverses the CWA through this evening. SBCAPE values have
already reached in excess of 2000-2500 j kg which will contribute to
thunderstorm intensification and the increasing possibility of some
severe thunderstorms. Damaging wind gusts will be the primary threat
in the strongest storms with steep low level lapse rates and
plentiful moisture. While some hail is possible, less impressive mid-
level lapse rates will tend to reduce the large hail threat a bit.

Coverage of showers and thunderstorms will gradually diminish
overnight after sunset as daytime heating is lost and the
aforementioned impulse moves eastward.

The cold stationary front currently residing to our northwest will
continue to slowly sag into to our area on Tuesday. The proximity of
this boundary as well as continuing southwest flow aloft will
contribute to additional scattered showers and thunderstorms on
Tuesday afternoon. Deep layer shear will not be a factor tomorrow as
it is today, so while showers and thunderstorms can again be
expected on Tuesday, threat for strong severe thunderstorms will be
low.

Rw
long term Wednesday through Monday ...

models are coming into better agreement for the late week system.

Confidence is increasing on showers tstorms and have therefore
increased probabilities. No other major changes planned. Previous
long term discussion follows...

previous long term Tuesday night through Sunday ...

the long term remains unsettled with basically a west or
southwest flow aloft across the southern states... And low pressure
continuing across the great lakes. A moist air mass is expected
to persist and a series of short waves will cross the area through
the period. Breaks in the precipitation will be hard to time. So
the overall pattern remains similar with chance or slight chance
pops each period. Gfs ECMWF hint at a surface front pushing into
ga Wednesday night into Thursday with somewhat drier air but not
confident enough on this to make any big pop changes.

00z update...

mainlyVFR conditions currently outside of convection. Should see
scattered MVFR or lower conditions developing by 06z and impacting
most TAF sites to some extent between roughly 08z and 16z. Light
westerly winds, 5kt or less, will prevail through 14z, increasing to
7-10kt after. Isolated convection across northwest georgia and
northern alabama is expected to diminish between 00z and 06z as we
lose surface heating. Right now I do not anticipate any impacts at
the TAF sites. Scattered convection will redevelop Tuesday, mainly
between 16z and 04z.

Atl confidence... 00z update...

medium most elements, especially concerning timing of any convection
and MVFR or lower conditions early Tuesday.

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.
