short term today through Tuesday ...

mostly high clouds across the area this morning but things are
expected to change. A frontal boundary entering north ga with
increased moisture and instability across the area will lead to
more widespread thunderstorms activity this afternoon and evening.

Expecting scattered convective to develop after 18z as cape
values peak around 2000-3000 j kg range. Any thunderstorms that do
develop should be heavy rain producers with pws in the 1.6 to 1.8
in range through tues morning. Some thunderstorms are expected to
be strong to severe with favorable 0-6km shear around 30-35 knots
contributing to the severe threat this afternoon evening. The
primary threats will be damaging wind gusts with some marginally
severe hail and heavy rainfall.

The main frontal system pushes into central ga by Tue morning and
appears to stall. There is still some decent instability and
moisture across the area but it does not appear that things will
weaken some so not expecting as much convective coverage tues as
today.

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.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
