Synopsis
High pressure will gradually build across the southeast through
Tuesday. A front will stall over the area Wednesday and
Thursday followed by weak troughing inland.

Near term through tonight
Strong NVA and subsidence associated with a shortwave ridge
over the area should preclude convection while producing a hot
day across the area. Sunny skies will prevail much of the day
with only a small amount of cumulus, mainly late in the day.

A pronounced shortwave is forecast to move in from the west this
evening, likely preceded by a decaying MCS from upstream. Model
guidance including high-res convection allowing models show only
a broken band of showers and tstms moving in from the west
after 23z. Thermodynamic profiles do not look terribly
impressive this evening though we could have enough built-up
instability to allow for isolated severe thunderstorms with
damaging winds the primary hazard.

Heat indices are still expected to top out in the 105-108f range
along the eastern half of the area where mid 90s temps and
low mid 70s dewpoints overlap for a few hours. The existing heat
advisory still looks good.

Overnight: any convection lingering will translate well offshore
and quiet weather is expected with the land breeze pushing over
the atlantic with a west surface flow.

Short term Tuesday through Thursday
The mid-levels will consist of semi-zonal flow over the southeast
with gradually building heights. At the surface, high pressure will
be over the southeast on Tuesday. A weak cold front will approach
from the northwest Tuesday night. The front will stall over our
nearby our area Wednesday into Thursday, while gradually
weakening dissipating. Models show strong subsidence in place
Tuesday and Wednesday and lower than climo moisture. We removed
mentionable pops and are only expecting some fair weather clouds.

Thursday the moisture and instability starts to return, so we have
chance pops, mainly along the sea breeze. The combination of 850 mb
temperatures, thickness values, and lack of convection should lead
to above normal temperatures Tuesday and Wednesday with highs in the
middle 90s away from the beaches. Highs should be a bit cooler on
Thursday, mainly due to the sea breeze and convection. Additionally,
heat index values could approach 105 f Tuesday for the coastal
counties, which could prompt heat advisories.

Long term Thursday night through Monday
Surface troughing will prevail across the southeast. This will bring
our area the typical afternoon evening showers and
thunderstorms.

Aviation 18z Monday through Saturday
Vfr through 18z Tuesday. There is a slight chance that lingering
convection will make it to the TAF sites late this evening or
early Tue am. Chances are currently too low to warrant a mention
in the 18z tafs.

Extended aviation outlook: brief flight restrictions are possible in
afternoon evening showers thunderstorms Thursday and Friday.

Marine
High pressure will gradually build across the southeast through
Tuesday. A front will stall over the area Wednesday and
Thursday followed by weak troughing inland. Winds seas will
remain below advisory thresholds.

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.
