957 pm edt Sat aug 19 2017

Synopsis
A cold front will become stationary across the area tonight into
Sunday, then dissipate early next week. Another cold front will
approach the area in the middle of next week and move through
the area by the end of the week.

Near term overnight
As of 955 pm sat... Latest sfc analysis shows 1000mb low over
northern quebec, with attendant cold front draped through the ne
us, and down into eastern nc. Front looks to be extending from
ne nc down through the coastal plain and back into central nc
this evening. The front will remain nearly stationary across the
area tonight. Latest radar imagery shows shower activity
pushing well offshore and expect pred dry conditions overnight
with clouds gradually clearing. Areas of fog possible overnight,
with clearing skies, winds decoupling and temps reaching near
crossover temps. Added fog to forecast based on good agreement
between high res guidance and forecast soundings. Overnight lows
in the low to mid 70s inland, and mid to upper 70s along the
coast.

Short term Sunday
As of 3 pm sat... A still hot but mainly dry airmass for the
majority of the area. Slightly higher moisture will be found
near and south of the front itself, and that is where we will
confine precip chances to just a slight chance. Highs will be in
the lower 90s along the coastal plain inland to mid upper 80s
at the beaches.

Long term Sunday night 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 02z Sunday through Thursday
Short term through Sunday ...

as of 630 pm Saturday...VFR conditions currently, with ifr fog
possible overnight and early Sunday morning. Precip will
continue to move east of the sites in the next hour or so
becoming pred dry overnight. Skies will gradually clear, winds
will be calm and temps are expected to reach near crossover
temps overnight, so widespread fog, locally dense at times, will
be possible. Fog and stratus should lift quickly after sunrise
Sunday morning becoming predVFR. Isolated showers and storms
possible Sunday, with best chances S E of the sites.

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 Sunday ...

as of 955 pm sat... Latest obs show winds SE SW 5-15 kt with
seas 2-3 ft. Quiet boating conditions in the short term with a
stationary front over the inland areas. South of oregon inlet
winds will be mainly south to southwest 5-15 knots with seas 2-4
feet. North of oregon inlet and on the albemarle sound winds
will be variable 5 to 10 knots with seas 2 to 3 feet.

Long term Sunday night 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.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
