6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

Synopsis for coastal waters from surf city north carolina to south santee river south carolina out to 20 nautical miles.. High pressure will migrate slowly across the area and then offshore on Sunday. A cold front will approach from the west Monday night, and then move offshore during Tuesday and may bring a brief period of small craft advisory conditions. High pressure will build in from the west Wednesday and Thursday.

Synopsis
Mild temperatures for january, will prevail through early next
week. A cold front will bring showers Monday night into Tuesday
morning. Temperatures will be near normal Wednesday and
Thursday as high pressure builds in from the west. The high
moves offshore Friday and Saturday with temperatures warming
above normal.

Near term through Sunday
As of 900 pm Saturday... Considerable high cloudiness beginning
to overspread the fa from S to N this eve. These clouds along
with a light SW wind should keep most areas from dropping below
freezing. Dewpoints have also increased considerably from
earlier in the day. We are forecasting low temps mainly in the
mid and upper 30s, although a few temps in the lower 30s are
expected, mainly across NW zones.

A small eastward jog of surface high pressure through the
period; the center of which GOES from ga to overhead. Looking at
850mb progs, there does appear to be a weak sense of cool air
advection. Forecast soundings show Sun should have deeper
mixing. The end result is a milder afternoon with highs in the
mid 60s area-wide.

Short term Sunday night through Monday night
As of 300 pm Saturday... Concern this period involves a cold
front which will likely be along or just west of the coast
Tuesday morning. Ahead of this feature, Sunday night through
Monday evening, large high pressure offshore and gradually
amplifying ridge aloft will drive WAA in a strengthening warm
sector ahead of the aforementioned front. 850mb temps of around
7c early climb towards 10c late, and with abundant dry air
persisting in the column at least through Monday eve, sunshine
will be prevalent. This suggests temps climbing to well above
normal, reaching near 70 Monday after lows Monday morning only
around 40.

The pattern begins to shift Monday night as a deep upper low cuts
through the great lakes. Ahead of this feature, diffluence will
increase and moist advection permeates into the carolinas. Although
the guidance differs slightly in timing, with the NAM being the
fastest, the overall evolution is similar from each model. Although
much of the forcing ejects NE away from the cwa, LLJ rises to above
50 kts with MLCAPE climbing to 200-400 j kg, setting up the
potential for an hslc event into Tuesday morning. However, very dry
air above 600mb appears to be limiting, and sherbe values peak below
1 across the cwa. SPC does not even mention general thunder
locally, but gusty winds and a brief period of heavy rainfall is
possible late Monday night. Overall however, do not expect a
high QPF or significant weather event with the fropa.

Cold advection lags well behind this boundary, in fact, it doesn't
occur until a secondary boundary crosses on Tuesday, so mins Monday
night will be closer to typical seasonal highs, low 50s most
locations.

Long term Tuesday through Saturday
As of 300 pm Saturday... Cold front in the area as the period
begins is quickly lifted east-northeast as 5h trough, associated
with great lakes 5h low, moves northeast. The bulk of the
dynamics and moisture with this system end up passing to the
north, limiting local precip chances the first half of tue. This
setup also helps keep the bulk of the cold air north of the
area. Secondary cold front arrives Wednesday night, but even
this feature lacks strong cold advection. Mid-level pattern in
the wake of the exiting trough is relatively flat into the end
of the week, helping quickly move surface high west to east.

Late next week 5h ridge starts to build over the southeast as 5h
trough digs over the western conus. This will lead to an
increase in deep moisture return very late in the period, but at
this point confidence is very low and not quite ready to carry
any mentionable pop. Temperatures above climo early in the
period will dip near climo midweek following the passage of the
secondary cold front. Temperatures bounce back above climo fri
and Sat as surface high off the coast and deep southerly flow
begins a period of warm advection.

Aviation 00z Sunday through Thursday
As of 00z...VFR this 24 hour TAF valid period. High pressure
will move over the terminals by morning. Tafs indicate variable
winds AOB 5 kt the entire period. Wind directions most likely
will be southeast Mon afternoon especially southern terminals.

There will be an increase in mid and upper level moisture by
morning. Densest clouds CIGS should remain south.

Extended outlook...VFR. Possible MVFR shra late Mon early tue.

Marine
Near term through Sunday ...

as of 900 pm Saturday... High pressure will build directly
overhead through sun. This should result in SW winds of 10 to
15 kt veering to NW and N through Sun morning before becoming
light and variable in direction. A developing seabreeze will
remain quite weak Sun afternoon. Seas of around 2 ft tonight
will subside to 1 ft during sun.

Short term Sunday night through Monday night ...

as of 300 pm Saturday... Placid marine conditions Sunday night
will ramp up quickly during Monday as a cold front approaches
from the west, and an SCA is likely before the short term ends.

High pressure over the area will push offshore Monday, leaving a
weak gradient and light southerly winds becoming SE and climbing to
around 10 kts by late Monday. During this period, significant seas
will be just 1-2 ft. Late Monday and especially Monday night, the
gradient tightens and southerly winds increase rapidly to 20-25 kts,
driving seas to 4-6 ft with a short southerly wind wave predominant
in the spectrum. This will create short and steep waves, and likely
necessitate an SCA that will persist into Tuesday.

Long term Tuesday through Thursday ...

as of 300 pm Saturday... Cold front in the area at the start of
the period will move east across the waters Tue morning. Winds
will veer from south-southwest to west and then northwest later
tue and Tue night. Although cold advection is lacking, the
gradient will keep speeds in the 15 to 20 kt range into wed
morning before starting to relax and allowing speeds to drop.

Reinforcing shot of cooler air arrives late Wed night, as the
surface high west of the area shifts east. Northerly flow
increases as cool surge arrives and winds become northeast. Seas
at the start of the period will probably warrant a continuation
of SCA into the first half of tue, but offshore flow is likely
to knock seas under 6 ft by midday. Seas continue a steady
diminishing trend Tue night and wed, dropping to 2 ft on wed
before starting to build late Wed night as the cold surge
arrives. Cold surge will push seas to a solid 3 ft with
potential for isolated 4 ft as the period ends.
