Synopsis
Upper ridging will weaken today into early next week. Along
with the troughing moisture will increase across the area with
slowly increasing chances of thunderstorms through Wednesday. It
will remain hot today with heat index values peaking between
105 and 110 degrees.

Near term until 6 am this morning
Subtropical ridging will continue to extend into the region
through tonight. Lee side troughing will remain over the
upstate. Convection has ended and mostly clear skies expected.

Overnight low temperatures will be in the middle 70s. Fog is
not expected due to a well mixed boundary layer.

Short term 6 am this morning through Monday night
Synoptic situation will continue changing Sunday and Monday as
the upper level trough digs into the eastern us and the upper
level ridge retreats to the south. Southwest winds on Sunday
will push gulf moisture northward with pwat values exceeding 2
inches from the late morning hours through Monday night.

Instability will again be moderate to strong Sunday... However
minimal divergence aloft will work to suppress convection. As
such expect a slight increase in pops due to the combination of
moisture and instability on Sunday and with slightly better flow
aloft Monday another slight increase in pops. With the freezing
level above 15 kft expect the main threat from thunderstorms to
remain damaging wind gusts... However with slow storm movement
expected will also need to monitor for locally heavy rainfall.

With the upper level trough over the eastern us and increased
cloud cover temperatures will moderate slightly with afternoon
highs in the mid 90s Sunday and low 90s Monday.

Long term Tuesday through Saturday
Models remain in good agreement through the long term with the
upper level trough exiting the region Tuesday then returning
Thursday through Saturday as the next system drops from canada
into the great lakes region. This will keep the forecast area
stuck between the upper level ridge to the south and the trough
to the north and under an influx of gulf moisture. As such have
remained with chance pops through the long term with
temperatures near normal with highs in the low 90s and lows in
the low to mid 70s.

Aviation 06z Sunday through Thursday
Vfr conditions are expected to prevail at the terminals through
the forecast period. Tonight will feature mainly clear skies
and relatively light winds at the terminals under the influence
of high pressure. The development of a low-level jet tonight
should inhibit fog formation. A strengthening southwest flow on
Sunday will allow increased moisture to advect into the area,
with scattered showers and thunderstorms expected to develop in
the afternoon. Given uncertainty in the coverage and timing of
thunderstorms, have kept mention out of the tafs at this time.

Extended aviation outlook... Increasing chances of afternoon evening
thunderstorms, and late night early morning fog stratus, Monday
through Wednesday.

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.
