short term today through Sunday ...

an upper trough continues over the SE CWA and drifts into the
northern gulf of mexico during the day as more or a weak upper low.

This seems to give the best chances for highly diurnal convection to
the far N and far southern portion of central ga as these 2
locations are where the best forecast instability is located. At
this time, my thinking is that the precip potential should only go
into the early evening hours tonight.

For Sunday, the upper low drifts W along the gulf coast states with
hurricane maria moving N over the western atlantic. A surface ridge
of high pressure will have built down the appalachians. This seems
to keep precip chances too low to mention in the forecasts at this
time.

A warm airmass continues over the area with forecast high
temperatures running 4-7 degrees above normal today and 3-5 degrees
above normal for Sunday. Forecast low temperatures are running around
5 degrees above normal for tonight.

Overall confidence is medium to high.

long term Sunday night through Friday ...

no real changes to the recent extended forecast trends seen with this
model cycle. Medium range models continue to keep the region under a
large, but not particularly strong, upper-level ridge through all
but the tail-end of the period. Upper trough breaks down the ridge as
we head into Thursday Friday of next week and a surface trough
develops across the coastal carolinas and into central south georgia
in the wake of maria as she sweeps up the east coast. Persistent
northeast to north low-level flow keeps the region stable through the
period, and this stable airmass and the absence of strong upper
dynamics or low-level forcing keeps pops low with this late-week
system. Dry and above seasonal normal temperatures reign until then,
replaced by more seasonal temperatures as we head into next weekend.

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.
