Synopsis
Ridging over the region will weaken on Monday as a frontal
boundary slowly slides into the area. The front will stall over
the area Tuesday with chances of showers and thunderstorms each
day through next weekend.

Near term until 6 am this morning
Earlier convection has shifted east of the area and dissipated
with only some passing high clouds over the forecast area at
this time. No additional rain is expected through dawn Monday.

Another convective complex is lifting northeastward across the
central gulf coast states but is not expected to reach the
forecast area by 12z and is forecast to lift northward into
north georgia. Although abundant low level moisture remains over
the area there is a forecast 25 knot low level jet which should
help mitigate fog formation.

Short term 6 am this morning through Tuesday night
Frontal boundary will continue moving toward the area on Monday
as the upper level ridge further weakens. Monday night the
front will move into the forecast area and stall across the area
Tuesday and Tuesday night. Main focus for the short term will
be convective potential as well as potential for severe
thunderstorms. Instability on Monday will be moderate to strong
with lis around -5 and CAPE around around 1500 j kg. With dry
air in the mid and upper levels there will be potential for
damaging winds and with wet bulb zero rising to around 12 kft
the potential for hail will be lower. With intersecting
boundaries and instability into Monday night expect scattered
convection into the overnight hours. SPC continues to have the
area under a slight risk for Monday as well. Temperatures Monday
afternoon will be in the lower 90s with lows Monday night in
the upper 60s to low 70s.

Tuesday will be similar... However with the front stalling over
the area expect the best chances for convection to along and
south of the front. Instability Tuesday will be strong and with
dry air persisting in the mid and upper levels will again see
potential for damaging winds and lower threat of hail. With a
weak pressure gradient there is also potential for a sea
breeze... Models currently depict this remaining near the coast
and triggering convection however if this moves further inland
this could trigger additional convection. Tuesday afternoon
highs will be in the upper 80s to around 90 with overnight lows
in the upper 60s to around 70.

Long term Wednesday through Sunday
Models are in good agreement into next weekend as the weak
surface front remains stalled over the region and a series of
weak upper level disturbances cross the area. This will keep
chances of mainly diurnal showers and thunderstorms in the
forecast each day through Sunday. Concern with convection for
Thursday onward will be potential for heavy rainfall as high
pressure over the western atlantic will result in southerly flow
and open the area to moisture from the gulf of mexico.

Temperatures through the long term will be near normal.

Aviation 06z Monday through Friday
Vfr conditions expected through the TAF period outside of
showers and thunderstorms Monday afternoon and evening.

Earlier convection has ended and only high cirrus clouds are
traversing the forecast area. Abundant low level moisture is in
place but a 25 knot low level jet should help keep the boundary
layer mixed and limit fog formation, although ogb already
showing lowering vsbys so will include a window of possible MVFR
vsbys from 08z-11z there.

A frontal boundary near the area will provide a chance of
showers and thunderstorms late Monday afternoon and evening.

Confidence in timing and exact location difficult so will
include only vicinity showers with this forecast generally after
21z. Winds will be light overnight and will pick up after
daybreak on Monday out of the west-southwest to around 5 to 10
knots.

Extended aviation outlook... A cold front will stall over the
region through early next week. The front will help support
scattered thunderstorms and possible restrictions.

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.
