Near term through tonight ...

the region will be between high pressure to the southeast and a
trough of low pressure to the northwest this period. Convection is
expected to initiate due to diurnal instability this afternoon. The
chance for storms will then continue through the afternoon, with
activity dissipating in the evening due to loss of heating. With the
low level flow from the southwest, the east coast sea breeze will
struggle to get past i95. The sea breeze boundary may help to
enhance storms later in the afternoon in the i95 corridor. Clouds
will decrease tonight, with mainly high clouds created by daytime
convection passing through.

Temperatures will continue to be above normal this period.

Short term Friday through Saturday night... Weakening upper
ridge with high moisture levels over the area will continue the
scattered diurnal convection. The higher coverage of storms will
be inland where afternoon seabreezes will merge by early evening.

Locally heavy rainfall will occur with a slow cell motion to the
north.

Long term Sunday through Wednesday... A weakness in the
subtropical ridge will be over the area during the period. A
moist SW flow will result in scattered to numerous storms each
afternoon and evening. Storms will be more numerous over eastern
zones as increasing SW winds will produce seabreeze mergers closer
to the east coast next week. Temperatures will be near average
levels.

Marine... The region will be between high pressure to the east
southeast and a trough of low pressure to the northwest into early
next week.

Rip currents: SE ga: low risk through Friday
ne fl: moderate risk through Friday

Aviation 06z TAF period... With the exception of patchy fog
that may develop inland early this morning possibly affecting
kgnv, prevailingVFR conditions are expected this morning.

Convection is expected to initiate this afternoon, with scattered
storms through the afternoon and evening. If these storms affect
an area terminal, restrictions and gusty winds are anticipated.

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.
