Short term /today through Sunday/
Expect enhanced southerly moisture transport to allow for midlevel
cloud deck today (possible breaks here and there), though the
approaching cutoff trough to the west and upper level vorticity
advection will ramp up shower chances by this evening. Orographic
effects should aid some isolated shower development in the NE this
afternoon. Progged thermal profiles are not very impressive in the
form of attainable CAPE for overnight tonight as the main
instability axis stays just west near the al border due to a
lingering mid level cap present. Have kept thunder mention mainly to
chance in the areas of likely shower coverage.

Sunday will have greater chances of storms and even isolated strong
to severe for north ga as the occluded front approaches and main
wave energy swings around the aforementioned cutoff low in a more
unstable airmass. Bulk deep layer shear of 35 to 40 kts helps
justify a marginal risk and main threat of damaging wind with the
strongest development.

Resultant temps around 5-7 degrees above climo with highs both today
and Sunday generally in the 70s and again abnormally warm overnight
lows due to the ample moisture/cloud coverage.

Long term /Sunday night through Friday/
The weekend system will be exiting eastward at the beginning of the
extended Sunday night. Following closely on its heels will be the
next system for late Monday into Tuesday. The upper trough will
track across the area while the surface low traverses into the great
lakes region. Given a continued warm and moist airmass in place,
some thunderstorm activity can again be expected. While the highest
forecast instability values continue to be highest to the west of
georgia, there will be sufficient instability for a few stronger
thunderstorms during the late Monday into Tuesday time frame. Shear
values continue to be middling with 0-6km values less than 40 knots
indicated.

The aforementioned system will propagate east of the area by late
Tuesday. Wednesday will bring generally drier conditions to the area
due to upper ridging, but this will also be brief as the active
weather pattern will continue. A closed low evident over the
southwestern u.S. Will be barreling eastward by late week. Models
continue with discrepancies in the handling of the evolution of
this system as it heads our direction. Regardless, shower and
thunderstorm chances will once again be quickly increasing by late
Thursday into at least part of Friday.

Model disagreement unsurprisingly becomes even more pronounced after
the late week system; however, the active overall pattern looks
likely to continue.

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.
