short term tonight through Saturday night ...

its been a nice day today but things are definitely going to change
over the next 12-24 hours. Tropical storm nestor, currently located
in the central gulf of mexico, is expected to continue moving
northeastward through Sunday morning. The models continue to show
some minor differences in speed and location of the system, but
overall it is expected to move northeast fairly quickly making
landfall along the fl panhandle just before daybreak Sat morning.

Rain is already beginning to push onshore the la ms al fl coast and
is expected to continue moving northward over night. This system
will move into south ga Sat morning and into central ga sat
afternoon evening. It will continue moving NE into the carolinas sat
night into Sunday morning. This is a fairly weak tropical storm and
is not expected to cause any major damage to the area. The biggest
concern is because we are in a drought right... And with the
increased winds and rain we will see some trees falling across
central ga. Winds will increase into the 20 to 25 mph range with
gust to 35 mph Sat afternoon. The models are also showing pws
increasing to the 2+ inch mark, so some periods of heavy rain will
be possible. Rainfall totals from early Saturday through early
Sunday are around a half inch to 1 inch for areas north of the
interstate 85 corridor... To 1 to 2.5 inches for areas south of that
line. Some locally higher amounts will be possible especially across
east central portions of the state.

High temperatures are expected to remain well below seasonal norms,
with highs in the 60s and lower 70s and some 50s across the
mountains and northeastern georgia. Low temps tonight and Saturday
night will be in the 40s and 50s.

long term Sunday through Friday ...

general forecast trends remain unchanged through the extended
forecast period as medium-range models continue to show fairly good
agreement through next week. Dry and mild to start the period Sunday
into early Monday as southwesterly upper-level flow amplifies ahead
of the next upper trough digging into the high plains. Precipitation
chances return by Monday afternoon ahead of another relatively sharp
cold front, peaking Monday night into early Tuesday as the front
sweeps through. Instability still looks to be somewhat limited, but
moderate to strong forcing and ample shear keeps at least a small
chance for severe thunderstorms in the picture. Air mass behind the
cold front is not looking particularly cold as the upper flow
quickly turns zonal through the middle of the upcoming workweek.

Next system digging into the middle of the country as we head into
the end of the week with precipitation chances once again
increasing.

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.
