Synopsis
A cold front will stall south of the area Sunday. A system off
the florida coast through the weekend will move northward and
off the southeastern coast early next week. This will help keep
a chance for showers and storms in the forecast.

Near term until 6 am Sunday morning
Cool, dry air will move into the area tonight behind a cold
front. Moisture will be shallow, limiting pops overnight to a
slight chance of a light showers or drizzle. Temperatures have
been far cooler than model guidance so far tonight and lows
will likely be cooler than even the coolest model guidance. Lows
may be in the low to mid 60s over much of the area. Expect
stratus to remain in place overnight with wind helping to limit
the chance of fog.

Short term 6 am Sunday morning through Monday night
The cold front will be just off to the south of the forecast area on
Sunday. Surface high pressure centered well off to the north across
the upper mid-atlantic and new england regions will be ridging
southward into the region through the period. Surface low is
forecast to develop off the florida peninsula on Sunday, then track
northeastward off the southeastern coast into Monday. This low is
being monitored by the hurricane center for possible development.

Even so, the low is expected to remain offshore. Some atlantic
moisture from the low offshore may push inland enough to bring some
cloud cover on top of the wedge flow, and may be able to produce a
few showers across the eastern most portions of the CWA each
afternoon. The expected clouds will combine with the northeasterly
low-level flow to actually help to keep afternoon temperatures below
normal both Sunday and Monday.

Long term Tuesday through Saturday
The surface ridge will still be across the area beginning Tuesday,
although it will be weakening as a deepening upper low across the
upper mid-west pushes eastward. This will drive another cold front
towards the region by Wednesday, and east of the CWA by Thursday.

The stronger upper energy associated with this system is forecast to
remain well off to the north of the region, but still can not
completely rule out some organized convection over the area by
midweek. By the end of the week, showers and storms will be isolated
to scattered, and more diurnal. Temperatures will rebound back
to being close to normal by the end of the week, with readings
in the upper 80s to low 90s.

Aviation 01z Sunday through Thursday
The cold front has moved south of the cae cub terminals and
weak cold air damming appears to be developing. Ceilings are
rapidly lowering across the area from north to south with
ifr MVFR developing. Ahead of the front a narrow broken line of
showers was moving into the csra. Convection appears to be
shallow given weak dynamics and weak instability. The widespread
thunderstorm threat appears to be diminishing although brief
visibility restrictions possible from ags to ogb in heavier
showers. Expect front to move through the ags terminal area
during the next hour and ceilings will lower.

The hrrr and lamp indicate ceilings will remain low overnight
as stratus strato-cu dominates. MVFR forecast ceilings through
Sunday as wedge may strengthen with low pressure offshore and
ridge building south from the mid atlantic. Rain chance appears
minimal with no significant lift.

Extended aviation outlook... Widespread ifr or MVFR conditions
may linger during much of the outlook period because of a front
remaining in the region.

Cae watches warnings advisories
Ga... None.

Sc... None.

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.
