Synopsis
High pressure builds in from the northwest today and tonight,
and settles immediately off the coast Wednesday. This area of
high pressure then shifts off the coast later in the week.

Near term until 6 pm this evening
As of 1045 am edt Tuesday...

latest analysis indicates that the sfc cold front has pushed
well S of the local area, now located over southeast nc. Sfc
high pressure is centered over the great lakes and is building
se into the mid-atlantic states, with area obs showing about a 3
to 5 mb rise in pressure over the past 6 hrs. Nnw winds, gusty
to 25 mph prevail on the eastern shore, with N to NE winds in
place elsewhere (also somewhat gusty to around 25 mph along the
coast). Temperatures as of 15z 11am range from around 70 f
across the N to the mid upper 70s over the s. Dew pts have
dropped into the lower 50s N but remain in the lower 60s in ne
nc. Mostly sunny and pleasant this aftn with just some scattered
cu developing. Highs will range from the lower 80s in interior
ne nc and south central va to the lower-mid 70s along the coast
and over the n.

Short term 6 pm this evening through Thursday
As of 400 am edt Tuesday...

dry and seasonal conditions will continue tonight into
Wednesday as high pressure shifts from the NRN mid-atlantic
tonight, to off the mid-atlantic coast Wednesday. Clear tonight
with low temperatures ranging from around 50f n, to the
mid upper 50s near and along the coasts of SE va NE nc. Favored
cold spots potentially drop into the upper 40s. Mostly sunny
Wednesday with high temperatures ranging from the low mid 70s
along the coast (around 70f md atlantic coast), to around 80f
well inland.

High pressure shifts east Wednesday night and Thursday allowing
the start of the next warmup. Models continue to show a NW flow
upper level flow pattern setting up that could allow for
another round of upstream convection to dive sewd. The 21 00z
gfs remains most aggressive with this, while the nam ECMWF are
generally drier and more capped. Timing can be a problem this
far out so pops are mainly ~20%. Low temperatures Wednesday
night are in the upper 50s to low 60s, followed by highs
Thursday in the mid upper 80s inland, to the upper 70s low 80s
closer to and along the coastlines.

Long term Thursday night through Monday
As of 330 pm edt Monday...

a few tstms are possible (highest chances ne) Thu night as a weak
disturbance in NW flow aloft tracks through the region. Otherwise,
strong upper-level ridging (and associated anticyclone) remains
centered over the southeast for much of the extended period while a
series of shortwaves track well to our N (from the upper midwest to
new england). As a result, very high confidence in above average
temperatures (and mostly dry conditions) from Fri through early next
week. A weak cold front may try to sneak into nrn ERN portions of
the CWA on Sat am, but no pcpn is expected with the fropa. The front
quickly washes out during the day on sat. Perhaps a brief
shower TSTM Sat night, but otherwise dry this weekend. Slight
chances for mainly aftn-evening showers tstms may return early next
week as the center of the anticyclone retreats slightly to the
southwest. Highs mainly in the low-mid 90s inland on Fri with mid
80s-around 90f near the coast. Still very warm on Sat with highs
ranging from the mid 80-low 90s (highest inland coolest over the
lower md ERN shore). Sunday may be the hottest day of the weekend
with highs will be in the mid 90s in most areas W upper 80s on the
lower ERN shore. Lows throughout the extended period will mainly in
the mid 60s-around 70f.

Aviation 15z Tuesday through Saturday
As of 700 am edt Tuesday...

a cold front is slowly pushing through NE nc as of 11z. The
wind will initially shift to NW behind the front, and then turn
nne 8-12kt primarily after 12z, and continuing through the day
with occasional gusts to 15-20kt. Mostly clear sunny conditions
are expected as high pressure builds in from the nw. High
pressure becomes centered N of the area tonight, with a light ne
wind under a clear sky.

High pressure remains over the region Wednesday, before sliding
offshore Wednesday night into Thursday. There is a 20-30% chc of
showers tstms Thursday aftn evening as a trough slides across
the area in NW flow aloft. Dry conditions are expected Friday
into Saturday as weak high pressure returns.

Marine
As of 410 am edt Tuesday...

a cold front will drop acrs the waters and push into the atlc
during this morning. Fairly modest pressure rises occur behind
the frontal passage, with high res guidance still showing a
surge of nnw winds in the wake of the front this morning. Winds
in the ches bay and the lower james river will generally run
15-20 knots with gusts to 25 knots. Accordingly, scas remains in
effect for these areas through 10 am this morning. Waves will
briefly build to 3 ft this morning, then subside to 1-2 ft by
this aftn. Winds offshore will also run 15-20 knots with gusts
up to 25 knots and seas 3-4 ft in offshore flow. Winds decrease
to 5-15 knots later today into Wed before swinging around to
the ese and then S by thu, as high pressure moves offshore and
ridging aloft builds over the southeast. There is the potential
for another cold frontal passage on fri.

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.
