short term today through Tuesday ...

cold front currently moving across al and central tn bringing
showers and isolated thunderstorms to the southeastern u.S. The
precipitation shield associated with the trough front will continue
to spread eastward with the actual front moving into far western ga
right around daybreak.

The cold front should move through most of the CWA by late
morning early afternoon. As the front exits the state... Instability
indices and shear values increase a bit and we may see some strong
to near severe storms this afternoon for areas east of an atl to mcn
line. The biggest threat will be periods of heavy rain... Gusty
winds... And frequent lightning strikes. The current forecast models
are showing this frontal system completely exiting the area by 00z
tues with a much drier and cooler airmass pushing into the area
through Tuesday.

Cooler temperatures and a drier airmass are expected behind the cold
front Monday night. Lows tonight will be in the 40s and 50s with
highs tues mainly in the 60s to near 70.

long term Tuesday night through Sunday ...

the long term portion begins with a very strong mid level trough
moving through with a very much mid winter appearance. This will
usher in the coldest air of this young fall season by far with mid
to upper 30s for the northern tier on Wednesday morning and now
only recovering to the upper 50s for Wednesday afternoon. There
will be some wrap around clouds with the passage of the trough but
at this time, moisture looks too shallow to result in any
precipitation.

High pressure remains in control for much of the week with
continued cold conditions during the overnight as there could be
some lower 30s for the NE mountains Wed night into Thu morning.

Next wx system will be on tap for the weekend as another cold
front moves into NW ga late on Friday. Does not appear at this
time as if this one will be able to tap into the gulf so front
will have to bring all its moisture with it. Looks limited at best
for precip chances and will limit to low end chance in the grids
for now.

Looks like the ECMWF has come around to the GFS solution of a
cleaner FROPA Sat into sun. Still will hold onto some pops through
the first half of the weekend for now but if trends continue,
should be able to drop altogether with subsequent forecasts.

Another shot of cold temps to follow the frontal passage with a
return to lows in the 30s.

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.
