Synopsis
A weak cold front will move across the area from the north today
and then stall and dissipate offshore tonight. High pressure
will extend over the area from offshore Monday through
Wednesday, then a stronger cold front will move through
Thursday.

Near term until 6 pm this evening
As of 300 am Sunday... Latest guidance is indicating weak surface
cold front wind shift line currently just north of area will
move south across area this morning, followed by weak high
pressure from the n-nw. No significant cooling or drying
expected with boundary passage except for temps a few degrees
cooler northern outer banks with NE to E wind. Deeper moisture
axis has shifted off coast with short wave trough moving into
area, and guidance in general agreement only isolated
shower TSTM threat along coast this morning and then over
southern sections this afternoon with weak convergence from sea
breeze combined with veering winds due to boundary passage.

Patchy fog and low clouds expected early this morning, mainly
for inland and southern coastal sections.

Max temps mainly upper 80s to lower 90s with mid 80s for
northern outer banks.

Short term 6 pm this evening through 6 am Monday
As of 300 am Sunday... Weak high pressure will extend over area
from n-ne with surface boundary dissipating offshore. Convective
activity expected to remain offshore during evening, but some
isolated threat along coast overnight with light onshore flow.

Patchy fog and low clouds possible for mainly inland sections
late tonight with mostly clear skies and light winds. Went with
mos blend for min temps, ranging from near 70 coastal plains to
mid 70s coast.

Long term Monday through Saturday
As of 3 pm Saturday... No significant changes to the forecast
with a quiet start to the week followed by a frontal passage
with widespread showers and thunderstorms mid week and cooler
and drier air for the end of the week into next weekend.

Sunday night through Tuesday... A front will wash out across the.

Area. The end result will be a slightly more comfortable but still
seasonably hot and humid air mass. There will be slightly higher
moisture near and south of the front itself, and that is where we
will confine precip chances. Highs through the period will be around
90 inland to mid 80s at the beaches.

Wednesday into Thursday... Best shot for precipitation over the
extended period will come late Wednesday into Thursday as a new,
stronger front moves into the area. With consistency in for this
period. Models for this feature, elevated pops to 60% Wednesday
night into Thursday.

Friday into Saturday... .Good news with the frontal passage will be
some significant relief from the heat and humidity. Expect mostly
dry conditions with highs in the lower 80s both Friday and Saturday
and lows falling into the mid 60s inland.

Aviation 07z Sunday through Thursday
Short term through 06z Monday ...

as of 145 am Sunday... Mix ofVFR and sub-vfr with patchy
fog stratus will continue until around 08z, then widespread ifr
to lifr mainly in fog expected at TAF sites until 12z-13z. Main
threat of lifr for kewn and koaj as both sites saw decent
rainfall Sat afternoon. Conditions improving toVFR by 14z and
persisting rest of TAF period. Isolated shower TSTM threat for
southern sections but not enough coverage expected to mention in
tafs. Winds will become NE this morning behind weak frontal
passage and then gradually veer to E and SE this
afternoon evening but speeds remaining below 10 kt.

Long term Sunday night through Thursday ...

as of 3 pm Saturday...VFR through Tuesday. SubVFR conditions
possible late Wednesday into Thursday in scattered showers and
storms.

Marine
Short term through tonight ...

as of 300 am Sunday... Current sw-w winds 5-10 kt will shift to
n-ne this morning as weak front moves south across area. Weak
high pressure will build in from N and extend over area through
tonight with winds gradually veering to E and SE 10 kt or less.

Seas mainly 2-3 feet today will become 1-2 feet tonight.

Long term Monday through Thursday ...

as of 3 pm Saturday... Quiet boating conditions continue through
Tuesday. During this period winds will be 10 kts or less with
wave heights 2 to 3 feet. With a boundary near the coastal
waters wind directions will vary quite a bit during this time
depending on location on the water (north to south). Tuesday
night winds begin to increase out of the south as a front
approaches and by Wednesday marine conditions become less
favorable. Ahead of the front southwest winds increase 10 to 20
kt, with seas building to 3 to 5 feet as a gradient tightens
ahead of the front. Timing of the frontal passage will begin
Wednesday night and by Thursday it should be through all the
waters. Seas will be 2 to 4 feet Thursday.

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.
