Synopsis
A frontal system will meander just off the coast through Tuesday night.

High pressure will build in from the west Wednesday through late
week.

Near term until 6 pm this evening
As of 710 am Monday... Precipitation has dissipated over land and
band of heavier showers and thunderstorms are now well offshore.

High-resolution models such as the hrrr rap and arw still
indicate some precipitation skirting the coast later today and
will continue with a slight chance along the coast, but would
not be surprised if things remain dry. Lower dewpoints should
lead to more sunshine and no precipitation further inland today.

With the lower dewpoints, especially inland, expect high temperatures
in the mid 80s cwa-wide today.

Short term 6 pm this evening through 6 am Tuesday
As of 3 am Monday... Surface ridge will slowly start to build in
from the west tonight pushing frontal boundary further
offshore as axis of mid-level trough approaches. This will serve
to push any precipitation even further offshore and will
forecast dry weather overnight. Pleasant temperatures for late
june expected tonight with lower 60s inland ranging to the lower
70s outer banks as dewpoints drop into the upper 50s to lower
60s.

Long term Tuesday through Sunday
As of 245 am mon... Scattered showers expected Tuesday. Then,
cooler and much drier air will spread into eastern nc Wednesday
through late week. Typical summertime pattern redevelops late
week into next weekend with temps a few degrees above normal and
scattered diurnal driven convection.

Tuesday through Tuesday night... A strong mid-level shortwave
will move through virginia and the carolinas Tuesday into
Tuesday night, supporting scattered showers and possibly a
thunderstorm. Forecast soundings indicate marginal instability
but strong shear and much cooler temps aloft, 500mb temps drop
to -12 -14c, could see some small hail especially a few hours
in the afternoon early evening. Will continue chance pops with
slight chance thunder, but think it will be isolated. Low level
thickness values and predominant N E flow support highs in the
low mid 80s Tuesday, with dewpoints in the mid 50s to mid 60s.

Much cooler Tue night with lows dropping into the upper 50s
inland and mid 60s along the coast.

Wednesday through Sunday... Strong high pressure will move overhead
Wednesday, and off the coast late week into the weekend. While
overhead, this high will provide a somewhat refreshing airmass
with lower humidities and cooler temps. Temperatures quickly
warm back up however, as southwest winds return on Thursday and
highs creep back to the mid 80s 90 degrees late week and the
weekend. Low temps in the 60s mid week, then warming back into
the 70s this weekend. Typical summertime pattern redevelops late
week into next weekend, with troughing inland and high pressure
offshore. Dry wx will cont through late week, with scattered
diurnal convective chances by the weekend. Will continue chance
pops inland sc along the coast Sat and sun, with isolated precip
overnight.

Aviation 11z Monday through Friday
Short term through 12z Tuesday ...

as of 715 am Monday... Patchy mid to high level clouds will
persist through most of the day today, thicker east of the taf
sites near the coast. Most of the remainder of the forecast will
be in theVFR category, but with winds likely to decouple inland
tonight, will forecast some radiational fog as temps dewpoint
drop with MVFR vsbys from about 08z-12z Tuesday morning.

Long term Tuesday through Friday ...

as of 245 am mon...VFR conditions are expected to prevail
through the period. Scattered showers and storms may produce
brief period of sub-vfr conditions Tuesday. As usual, patchy
fog stratus will be possible most mornings.

s SW by tonight ahead of next cold front, but speeds should
remain at 10 knots or less. Seas will remain at 3 feet or less
through the period.

as of 245 am mon... Generally benign and pleasant boating
conditions expected through late week. A weak cold front will
move through early Tuesday, N NW winds 5-10 kt early, becoming
ne E with seas around 2 ft. Surface high pressure will build
over the area Tuesday night from the northwest, crest over the

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.
