Synopsis
A frontal boundary will remain nearly stationary over southeast
virginia and northeast north carolina today into Sunday. Weak
high pressure will be over the area on Monday.

Near term until 6 pm this evening
As of 955 am edt Saturday...

morning fog and stratus are slowly scattering and lifting over
central and s-central va and the md ERN shore this morning. Warm
and humid with temperatures in the mid 70s to low 80s and
dewpoints in the low mid 70s.

A frontal boundary will remain nearly stationary over SE va and
ne nc during today. Pops will be 15-30%. Highs today will
generally be in the upper 80s to lower 90s, with mid 80s along
the atlantic coast of the ERN shore.

Short term 6 pm this evening through Monday
As of 400 am edt Saturday...

the frontal boundary will gradually get pushed to the SE very
late tonight through sun, as upper ridging starts to build in
from the w. However, the front does linger near the coast, and
the 17 00z gfs ECMWF nam continue to show a wave tracking along
the front over the coastal carolinas later tonight into sun
aftn. Pops of 20-50% will be over SE portions of the area for
the first part of sun. Lows tonight 70-75, followed by hotter
conditions sun, with highs in the upper 80s to lower 90s, and
potentially some mid 90s well inland.

The frontal boundary pushes well off the coast Sun night into
mon, as the upper ridge builds in from the w. Pops will be 15-30%
mon aftn with hot and humid conditions developing. Forecast highs
on Mon are 90-95, with upper 80s at the coast, after morning
lows of 70-75.

Long term Monday night through Friday
As of 300 pm Friday...

models continue to show a breaking down of the western atlantic
and western us ridges over the eastern third of the us next
week with a weakness developing in the ridge along the
southeastern us coast by midweek before a northern stream trough
slides across the great lake and northeastern us late in the
week. This is similar to yesterdays runs, although the timing on
the sfc cold front associated with the northern stream trough
is a bit slower than yesterday. Overall, this should lead to a
gradual increase in moisture and convection from Tuesday into
Thursday in advance of the front with more organized
precipitation with the cold frontal passage on Friday. How are
south the front will make it is still in doubt the models begin
to show the western atlantic ridge building back westward late
in the period and this could stall the front across SRN va nrn
nc. So have left pops across this area for Friday.

For temperatures, guidance has trended a little cooler with
this model cycle, with readings generally near normal next week
with highs in the upper 80s to around 90 most days and lows in
the upper 60 to mid 70s.

Aviation 14z Saturday through Wednesday
As of 300 am edt Saturday...

early this morning, conditions ranged fromVFR (ric) to ifr
(sby) at the TAF sites. Isolated showers were over the ERN shore
down into coastal NE nc. A frontal boundary will remain nearly
stationary over SE va and NE nc today into sun, keeping the
best chc for showers tstms over this area, but isolated activity
will still be possible anywhere over the CWA this aftn evening
and Sun aftn evening. MVFR ifr conditions, will continue to be a
possibility at the TAF sites later tonight into Sun morning.

MainlyVFR conditions are expected to prevail Mon and tue,
although a low probability of aftn evening showers tstms will
continue.

Marine
As of 140 am edt Saturday...

no headlines expected through early in the upcoming week. Hi
pres will remain nearly stationary off the coast. Very weak low
pres tracking NE along off the NE nc coast is shown on a couple
of the models during Sun which may briefing result in a period
of ene winds... Otw... Mainly se-sw winds AOB 10 kt through mon.

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.
