Update
Updated for the 06z aviation discussion.

update...

persistent light showers in NW flow continue for the northern
tier and at times extend southward into the metro. Have extended
slight and low end chance pops through 06z before tailing off.

Remainder of the forecast is on track and no changes are planned.

short term tonight through Wednesday night ...

current radar loop shows light showers increasing across the area as
they wrap around the back side of the exiting low pressure system.

Currently the main low center is right along the ga sc border and is
moving slowly ne. It will continue pushing into the mid atlantic states
through Wed morning pulling the lower ceilings and precip NE along
with it. Winds behind this system will also pick up Wednesday
especially across NE ga with winds in the 10-15kt range gusting 20-
25kt Wed afternoon. Not expecting much in the way of precip Wed as
we will be in between systems with slightly drier air over the area.

The second wave which is currently developing over the central
plains will push into the ms river valley Wed afternoon evening with
moisture and precip chances increasing across ga Wed night. The main
system does not move into western sections of the state until thu
morning but should begin to see some showers and isolated
thunderstorms move into the area ahead of this next system. There is
very little instability over the area Wed night so any thunderstorms
that do develop will stay below severe limits. Clouds will stay over
the area tonight so low temps will only dip mainly into the 50s.

High temps are expected to get up into the 70s across the area with
some 60s across the NE ga mountains.

long term Thursday through Tuesday ...

only tweaks made to the long term forecast with this update. Models
are converging with respect to a shortwave trough expected to move
through the SE CONUS Thursday through Friday morning. More
widespread showers and thunderstorms are expected, especially for
northern ga with this system but it shouldn't linger as much as
the last system has. MAX storm total QPF is expected to be
between 0.5-1" for northern portions of the forecast area, but
locally higher amounts will be possible. There are some
disagreements between model solutions regarding instability with
this next shortwave so conditions will need to be monitored going
forward.

Otherwise, near normal conditions are expected for the rest of the
long term period.

active wave train pattern continues through the fcst period with
the main focus on the strength and timing of two shortwaves. The
first is with pretty good model consensus consistency on swinging
through the area for Thursday. Have raised pops to likely for most
of CWA and included slight chance thunder mention given some
progged elevated instability (also how sensitive the environment
can be given any cloud breaks and increasing solar angle for this
time of year). Low level shear is lacking though deep layer values
are marginal enough to where we will need to monitor any
strong severe potential for more organized convection or enhanced
updrafts. Should not be as much of a flooding heavy rain issue
given how progressive it looks to be.

Next wave could be a bit less in amplitude though guidance has
less agreement on how far south the piece of energy digs or if it
cuts off going into late Friday early Saturday. Carried general
slight pops until more confidence is reached or moisture return
increases.

The weekend for now looks pleasant and ridge dominated. Temps
rebound to back above normal with even upper 70s for most areas
Sunday Monday.

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.
