What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

short term tonight through Wednesday night ...

ridging aloft will dominate the forecast area through the short
term. The water vapor curve shows much of the state in a drier air
mass with tropical moisture to our west and east. However moderate
cape... Lifted index values around minus three to minus five... And a
weak lee trough will support a few diurnal showers and
thunderstorms. Weak winds aloft should keep the storms nearly
stationary and heavy rain and damaging winds are possible. Look for
a similar pattern on Wednesday as the air mass is not expected to
change much. The ridge aloft gets suppressed a bit on Wednesday
evening into the overnight. This will allow a more southwest flow
aloft to bring an increase in moisture into north and west ga. Have
held on to mostly chance pops across the northwest Wednesday night.

Temperatures will remain hot but heat index values will remain below
advisory criteria tomorrow afternoon.

long term Thursday through Tuesday ...

shower and thunderstorm chances will be on the increase at the onset
of the long-term forecast period as the upper ridge over the
southeast flattens as a result of the trough digging into the
midwest. This pattern will funnel tropical moisture from texas
northeastward into the southeast, bringing pws over 2" into the area
by Thursday. Low pressure will continue to build into the mid-
mississippi valley by Thursday into Friday, and associated shortwave
disturbances rounding the base of trough will help increase shower
and thunderstorm coverage through late week over our area.

By weekend, upper flow transitions into more of a zonal flow. The
gfs favors a more of an active northwest flow by early next week and
enhanced shower and thunderstorm chances. Regardless, with plenty of
gulf moisture remaining in place, shower and thunderstorm chances
will linger.

Outside of showers and thunderstorms, temperatures will be hot.

Highs ranging from the upper 80s to mid 90s in combination with
dewpoints in the 70s will provide for heat indices from the upper
90s in north georgia to low 100s in central georgia. Current
forecast heat index values remain just below advisory criteria,
though appropriate heat precautions should still be taken.

00z update...

pretty much a persistence forecast although coverage of convection
Wednesday afternoon should be less than today. Otherwise
convection will dissipate over the next 2 to 3 hours withVFR
conditions expected through the forecast. CU field will develop
Wednesday morning with isolated to scattered convection developing
by afternoon. Winds will remain northwest to west less than 10
kts.

Atl confidence... 00z update...

high on all elements.

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.
