Synopsis
A weak cold front will drop into the northern forecast area
today, then lift back north tonight and Tuesday. Another cold
front will move through the area Thursday, then stall off the
coast into next weekend.

Near term through today
As of 230 am mon... Weak frontal boundary will be near across the
northern counties today with limited forcing aloft. Models show
several weak disturbances moving through the moist southwest
flow which will lead to scattered thunderstorms, especially
across inland sections this afternoon. Instability and weak
shear will limit any severe potential. Main concern will be
locally heavy rain. High temps mainly in the mid 80s, with a few
upper 80s inland from the coast.

Short term tonight
As of 230 am mon... The previously mentioned frontal boundary
will lift back north as a strong upper trof digs to the west.

Model time sections show moisture deepening ahead of
strengthening west-southwest flow, with still some vort energy
passing through overnight. Will keep chance pops going. Lows in
the lower 70s along the coastal plain to mid 70s elsewhere.

Long term Tuesday through Sunday
As of 3 am mon... Unsettled for the first part of the week, then
a cold front will push through the area Wednesday night and
Thursday with drier air moving into the area and precip chances
becoming more isolated to widely scattered.

Tuesday and Wednesday... Surface low will continue to strengthen
and move through the great lakes region Tue as attendant cold
front approaches from the west. SPC has the area outlooked in a
marginal risk for svr storms tue, and wpc outlooked the region
in a marginal risk for excessive rainfall. Instability looks to
be the limiting factor, but should be enough to generate storms
with mu CAPE values 1500-2000 j kg. Pwats climb to around 2.3
inches Tuesday afternoon and evening, with 0-6 km shear
increasing to 20-30 kt. Isolated strong to severe storms with
damaging wind gusts and locally heavy rainfall will be possible.

Scattered showers and storms will continue wed, though heavy
rain threat expected to wane as airmass becomes much drier
aloft. Highs in the mid to upper 80s, with lows in the 70s.

Wednesday night through Sunday... A cold front will push through
the area Wednesday night and Thursday, then likely stall off the
coast into the weekend as strong high pressure builds in from
the north. A much drier and more pleasant airmass will move into
the area. Expect precip chances to diminish as well, though will
continue sc low chance pops along the coast near axis of better
moisture. Expect temps below normal, with highs in the low to
mid 80s and overnight lows in the 60s to low 70s. Some guidance
has lows dropping into the upper 50s to low 60s inland Fri and
sat mornings. Upper ridge will strengthen over the area late
weekend into early next week as surface high remains centered
just to the west. Temps will gradually warm with precip chances
returning to near climo.

Aviation 06z Monday through Friday
Short term through tonight
as of 230 am mon... Sub-vfr CIGS likely through the early morning
hours mainly at pgv, iso and ewn with numerous showers and
thunderstorms moving through. Activity so far has remained to
the north of oaj but convection is expected there as well
through the rest of the overnight period.VFR should return to
all area terminals during the morning, but sub-vfr in scattered
storms expected again in the afternoon. Surface winds will be
from the southwest less than 10 knots.

Long term Tuesday through Friday ...

as of 3 am mon... Scattered to numerous showers and storms will
produce sub-vfr conditions at times Tuesday and Wednesday, best
chances during the afternoon and evening hours. A cold front
will push through the area Wednesday night and Thursday, with a
drier airmass moving in behind it for late week.

Marine
Short term through tonight
as of 230 am mon... Frontal boundary to the north forecast to
stay just north of the waters today, then lift north tonight.

Southwest flow forecast across the marine zones, with a rather
loose pressure gradient. Winds generally 5-10 knots over the
northern waters, albemarle sound and area rivers, 10-15 knots
elsewhere. Seas averaging 2-4 feet.

Long term Tuesday through Friday ...

as of 3 am mon... SCA conditions likely Tue night into wed. S sw
winds return for all waters Tuesday 5-15 kt early increasing to
10-20 kt in the afternoon. Seas 2-4 ft early building to 3-5 ft
Tuesday evening. Gradient tightens Tue night and wed, with sw
winds increasing to 15-25 kt and seas building to 3-6 ft. Sca
conditions likely to develop across the waters and pamlico sound
tue night and wed. A cold front is likely to push through the
waters Thursday then stall off the coast into the weekend. Winds
will shift becoming NE E 5-15 kt thu, and then move easterly
10-15 kt Fri with seas 2-4 ft.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
