Synopsis
Strong high pressure will build in from the north today as low
pressure moves offshore. The high will continue to extend
across the area through Thursday then slide offshore Friday and
Saturday. The next frontal system will impact the region Sunday
into Monday.

Near term through today
As of 330 am tue... Sfc analysis indicates low pres cold front
has pushed offshore as of early this morning. Some light showers
and or drizzle will continue until around daybreak, then drying
conditions today. The low will deepen rapidly as it pushes
further offshore producing a tightening pressure gradient across
the area today resulting in very windy conditions developing
along the obx. Winds will gust upwards of 50 mph at times. Gusty
winds elsewhere on the coast could gust upwards of 40-45 mph,
and further inland up to around 30 mph. See tides coastal
flooding section below for coastal impacts. High temps quite a
bit cooler than yesterday, only reaching into the upr 40s nrn
obx to the mid 50s SW zones.

Short term tonight
As of 330 am tue... High pres ridges into the carolinas tonight,
with centering over the great lakes mid atlantic region. Tough
temperature forecast tonight, and will be critical as E nc is
now in the growing season. Expecting some bndry layer mixing to
persist with NE gradient continuing. However, with low lvl
thicknesses only around 1300m, these values would suggest
freezing temps. With just enough mixing, do not expect more than
an hour or two of some locations inland reaching freezing or
below. If winds are less than currently forecast, chances for a
freeze increase. So will have to watch trends carefully on later
shifts to see if freeze headlines will be eventually needed. Td
vals expected to drop into the mid 20s, which would preclude
much in the way of frost.

Long term Wednesday through Monday
As of 300 am tue... Dry with a warming trend Wed thru sat. Next
front will impact region late this weekend into early next
week.

Wed through Saturday... The high pressure ridge axis will shift
off the new england coast though continue to nose southwest over
eastern nc through the period with dry weather expected. Gusty
coastal winds will cont Wed then grad diminish. Temps may be
close to freezing again for minimum temps early Thursday
morning inland, then moderate into the 60s by Thursday
afternoon. Building heights and thicknesses will lead to temps
rising above climatology by Friday into Saturday with lower 70s
fri and mid upper 70s Sat inland.

Sunday thru mon... Guidance indicates a strong trough will dig
into the ohio river valley on Sunday, with a surface low moving
from the southern great lakes into southern quebec, dragging a
cold front through eastern nc sometime late Sunday into Sunday
night. Differences cont amongst guidance with regards to
location timing and moisture assoc with the front so will cap
pops at chance. Temperatures remain mild Sunday with highs in
the low mid 70s inland to 60s beaches. Temps cool behind the
front Mon with highs mid 50s to low 60s.

Aviation 06z Tuesday through Saturday
Short term through tonight ...

as of 2 am tue... A mix of ifr toVFR observed acros the region
early this morning. Band of ifr stratus currently working
southward, and has moved into kpgv kiso, will continue south and
affect kewn koaj over the next several hours. This will be short
lived, as dry air will quickly work into the region by daybreak,
with eventual clearing skies later this morning. Winds will be
gusty today out of the north and gust upwards of 20-30 kt. The
gusty winds will abate by sunset, with generally around 5-7 kt
winds expected tonight.

Long term Wed through Sat ...

as of 300 am tue... High pressure building N of the region will
keep area dry with predVFR.

Marine
Short term through tonight ...

as of 330 am tue... Marine conditions will deteriorate rapidly
this morning as gusty north to northeast winds develop behind
the departing storm system. Winds across the marine area are
expected to increase from around 15 kt to over 35 kt within only
a couple of hours, between about 8z and 14z. Continue the gale
warning for all waters except the inland rivers where the small
craft advisory remains. Seas will build rapidly today with
guidance showing 10-15 ft north of ocracoke inlet to 6-10 ft
south by this afternoon. These dangerous seas will continue
through tonight with gale force winds continuing.

Long term Wed through Sat ...

as of 300 am tue... Gale warning continue for pamlico sound and
coastal waters thru mid to late Wed with SCA other wtrs. Nne
winds 25 to 35 kts Wed morn will diminish slowly to 20 to 30
kts late. Winds will cont to grad diminish as high pres builds
in with speeds 15 kt or less by late thu. The high will be over
region Fri with light and variable winds. As the high slides
offshore Sat winds become S less than 15 kt.

Seas of 8 to 13 feet early Wed (highest N and outer wtrs) will
very slowly diminish to 6 to 12 feet by Wed evening and drop
further to 4 to 8 ft thu. Despite very light winds fri
lingering swell will keep seas over the outer wtrs in the 4 to 6
foot range. The swell will slowly diminish into Sat but still
looks like some 5 foot seas cont over outer wtrs.

Tides coastal flooding
As of 300 am tue... The strong N NE winds today into Wed will
lead to very rough surf and poss some minor coastal flooding.

The greatest threat for minor coastal flooding exists for areas
along the southern pamlico sound later today into Wednesday
morning. The area of greatest concern is downeast carteret
county, where inundation of up to 2 feet for very low lying
areas is possible. A coastal flood advisory conts for counties
adjacent to the southern pamlico sound.

Additionally, very rough surf will develop for the beaches from
cape lookout n... Espcly for the obx N of CAPE hatteras and will
cont a high surf advisory for these areas... Some minor ocean
overwash could develop during high tides cycles N of CAPE hat
later today and tonight.

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.
