short term tonight through Tuesday night ...

freeze warning extended for a portion of N ga tonight. It's
borderline for some counties but at least close.

Otherwise a dry forecast continues through the short term with just
passing high clouds as a dry cold front exits the area this evening.

Forecast low temperatures are running about 2-9 degrees below normal
tonight and Tuesday night across the area. Forecast high temperatures
are running about 6-12 degrees below normal on Tuesday.

Overall confidence is high.

long term Wednesday through Monday ...

generally dry and seasonal conditions expected through the week
with no high-impact weather through the weekend.

A fast-moving clipper-like system will dive south from the
northern central plains, crossing the tennessee valley and southeast
regions Wednesday night into Thursday. System weakens and gets
absorbed within the main long-wave trough crossing the eastern
conus. System is also moisture-starved, so any organized areas of
precip will be short-lived at best, confined mainly across far north
ga very late Wednesday night through Thursday morning. Temps
expected to be warm enough to keep any precip in the form of rain,
however, cooling aloft associated with upr low running into drier
air near the sfc could support some light sleet mixed in with the
rain briefly at onset. Most areas will remain dry with this system.

Behind this system, a reinforcing shot of cooler drier air will
filter back across the area as high pressure remains in control. Upr
lvl ridge axis approaches the area over the weekend which should
allow temps to warm back up (several degrees above normal). Dry
conditions will prevail into early next week but models suggest a
stronger system coming out of the southern plains that could have
some impact over north central ga by middle of next week.

fire weather...

with a dry airmass in place, humidity recovery looks to be limited
tonight in the generally 50-80 percent range.

Another overall low dry rh day on Tuesday is expected with min
humidities running about 20 to 30 percent across the area. A
statement for high fire danger could be needed on Tuesday as
durations could hit 4 hours. N-e winds of around 10 mph or less
can be expected and briefly stronger for some areas during the
latter portions of the morning.

Min humidities for Wednesday are running 25 to 35 percent across the
area with winds mainly less than 10 mph and mostly light for the
mountains.

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.
