short term today through Wednesday ...

all in all a continued quiet short term forecast. The airmass is
remaining mostly dry except for high clouds and some lower level
moisture effecting central and portions of N ga. There is no
instability what-so-ever and no rain is expected.

A cold front is expected to wash out and dissipate as it approaches
n ga tonight. The parent surface high ridge and short wave ridge aloft
over the eastern-mid u.S. Will usher in a surge of drier air tonight
and Wednesday across the forecast area.

Forecast high temperatures are running around normal to around 4 degrees
below normal across the area today and Wednesday.

Forecast low temperatures are running within 4 degrees of normal
across the area tonight.

Overall confidence is medium to high.

long term Wednesday night through Monday ...

models are in good agreement for the upcoming long term period.

The remains of willa should help develop a low pressure system in
the northwest gulf that will move eastward along the gulf coast
and bring increasing tropical moisture to our area. Likely to
categorical rainfall chances still look okay for much of north
and central ga Thursday and Friday. A cold wedge will also
dominate the area during that time as the low tracks to our
south. Rain chances should diminish by Saturday as this low moves
northward along the atlantic coast. However... A broad upper trough
will be developing over the oh and tn valleys with a couple of
short waves passing through. This will keep low pops over much of
the forecast area through Sunday. Monday looks mostly dry as high
pressure starts to build in from the west.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
