Synopsis
Unsettled weather is expected through Thursday as a cold front
stalls near the area and several low pressure areas move along
it. High pressure will build in from the west Friday and
Saturday.

Near term /until 6 am this morning/
As of 120 am tue... Widespread light rain and drizzle across all
of the forecast area at present with no thunder. Do not expect
much change overnight so went categorical pops throughout and
removed mention of thunder. No changes to the forecast overnight
low temperatures with mostly areas between 65 and 70 degrees.

Short term /6 am this morning through 6 pm today/
As of 245 pm mon... Cold front will continue to approach from the
west Tuesday, as a weak area of low pressure develops along the
front then lifts through the coastal plain, and off the va
coast by Tuesday evening. Numerous showers and storms expected
with precip coverage expected to be more widespread than
previous days. Will continue likely to categorical pops.

Widespread clouds and precip expected, which will limit overall
instability, but could still see an isolated strong storm
develop with increasing shear. Periods of moderate to heavy
rainfall likely, as pwat values increase to around 2". Low
level thickness values, s/sw winds and cloudy skies support
highs in the upper 70s to around 80 degrees.

Long term /tonight through Monday/
As of 330 pm Monday... Latest models continue to indicate wet,
stormy period into Thursday, followed by much drier weather
toward the end of the week and weekend. Upper trough digging
from northern plains into SE us will lead to slow-moving frontal
boundary Tuesday night into Thursday. System will lift north and
east of area Thursday night with dry high pressure for Friday-
Saturday. Return of jet energy will bring return of convective
threat Sunday into Monday.

Tuesday night... Have leaned toward a 12z nam/ecmwf blend with a
secondary low moving along stalled frontal boundary SW to ne
across northern sections during the night. GFS shows a similar
short wave to these models but no surface reflection indicated.

Will carry likely pops all zones through the night with good
coverage of showers and scattered tstms with locally heavy rain
threat.

Wednesday... Models in general agreement with lull in activity
during the morning but kept pops 30-50% with frontal boundary
stalled across area. Short wave energy approaching again during
afternoon and increased pops to likely again for SW 2/3 of area.

Wednesday night... Another period of widespread showers and
scattered thunderstorms expected with likely pops all zones.

Threat of strong to marginally severe storms will increase
slightly with bulk shear up to 50 kt but instability and cape
will be limited. QPF will indicate potential for another one-
half to one inch additional rainfall.

Thursday... Evolving upper low and associated trough will move
into area with dry slot likely spreading in from SW during the
day. Main activity will be along coast in morning and moving
offshore during afternoon, but at least chance pops for all
zones during the day.

Thursday night... Continued chance pops during evening with upper
trough moving across, then drying expected overnight with deep
west to NW flow developing.

Friday-Saturday... Ridging surface and aloft expected to produce
dry period. GFS does bring short wave energy back quickly
across northern sections Saturday afternoon but appears to be a
fast outlier at this time.

Sunday-Monday... Increased short wave energy with surface and
upper ridges moving offshore will result in return of at least
chance pops for convective development each day.

Tuesday night-Thursday period will see min temps 5-10 degrees
above normal while clouds and precip will keep MAX temps a few
degree below normal. Near normal for Friday-Saturday, then above
normal for Sunday-Monday.

Aviation /05z Tuesday through Saturday/
Short term /through 00z Wednesday/...

as of 120 am tue... MainlyVFR at the area terminals with
occasional lower ceilings. Widespread light rain and drizzle
covers the area and will continue overnight. Rain will become
heavier during the day with embedded thunder, especially in the
afternoon. Ceilings will lower to MVFR as a result toward 12z
and continue through the day into tonight with visibilities
lower in heavier rain. Winds will be from the south to southwest
at less than 10 knots overnight, increasing to 10-15 knots
today, then diminishing to less than 10 knots tonight.

Long term /tue night through Saturday/...

as of 330 pm Monday... Sub-vfr likely in periods of heavier rain
and thunderstorms Tuesday night through early Thursday morning.

A return toVFR is expected Thursday night through Saturday
with drier weather building across the terminals.

Marine
Short term /through Tuesday/...

as of 120 am tue... Winds are s-sw over the coastal waters and
sounds at 10-15 knots with occasional gusts approaching 20
knots. Seas remain at 2-4 feet. No real changes needed to the
current marine forecast as SW winds will increase to 15-25 kt by
midday on Tuesday with seas building to 5-9 feet. SCA for the
pamlico sound and coastal waters starts around midday Tuesday
and will persist into weds for the pamlico sound and northern
waters and into late week elsewhere.

Long term /Tuesday night through Saturday/...

as of 330 pm Monday... Gusty winds will continue into Thursday
night while elevated seas will linger into Friday.

Low pressure moving along frontal boundary mainly inland of
waters will produce periods of SW 15-25 kt winds into Thursday.

There is some model differences on Wednesday with GFS indicating
wind shift and lighter winds for northern sections as front
stalls over central waters, while ECMWF and NAM keep front
stalled over northern sections with moderate SW flow for most of
waters. Have leaned toward ecmwf/nam with main result of
lingering elevated seas. Strongest winds likely Wednesday into
early Thursday with stronger low moving across to NW and could
see solid 20-25 kt over southern and central waters. Wind shift
to westerly behind front Thursday evening with speeds
diminishing into Friday night, followed by return to SW late
Saturday.

Nwps used for seas most of period. Heights 6-9 feet Tue night
will subside briefly to 5-7 ft wed, then build to 7-11 ft by thu
morning. Diminishing winds will allow seas to subside below 6 ft
Friday evening and to 2-3 ft Saturday.

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.
