Synopsis
Low pressure will track northeast across eastern nc late
tonight and Sunday. High pressure offshore will extend west into
eastern north carolina through mid week. A cold front will
approach late week.

Near term until 6 am Sunday morning
As of 945 pm Saturday... Precip has briefly ended most areas
with just lingering shra cst. Regional rdr shows increasing shra
far SE N carolina assoc with low pres. These shra and a few
tsra will spread NE and impact the area overnight. Best cvrg
with locally heavy rain likely greater than 1 inch will be near
cst. Have low chc to no pops currently that will will ramp up to
categorical cst to chc deep inland overnight.

Prev disc... Latest surface analysis indicates high pressure
offshore with a weak area of low pressure near charleston, sc,
lifting northeast along the coast. Quasi-zonal flow aloft with
weak shortwave troughs moving through the area, aiding in
convective development persistence at times.

Convection currently remains along a line from bladen county
ene to hyde county, with additional showers and thunderstorms
developing off CAPE fear moving towards the region. Will
maintain likely pops for these features near and just inland of
the coast. SPC mesoanalyses indicate a large swath of pwats at
or above 2.25 inches stretching from coastal ga to cape
hatteras. Given instability and shear remain weak,
localized poor drainage flooding remains the biggest hazard
through this afternoon and tonight. Overnight temps will remain
warm with minimum temps in the low 70s inland to mid 70s along
the coast and outer banks.

The area of low pressure currently near charleston, sc, will
lift northeast into eastern nc between 06-12z tonight. Deep
tropical moisture will be embedded in this system. Continued
previous trend of pops coincident with passage of low starting
late tonight. There may be a flood concern for the eastern
counties outside of the coastal plain, and will have to monitor
for a flash flood issuance with later updates.

Short term 6 am Sunday morning through 6 pm Sunday
As of 3 pm Saturday... By sunrise Saturday, the surface low is
expected to be near jacksonville, lifting northeast towards
norther dare county throughout the day. There will be a
precipitation gradient from west to east across eastern nc with
the low pressure passage, and continued highest pops for eastern
half of the area. QPF for the low passage ranges from a half-
inch inland to 1-3 inches along the coast from carteret county
to dare county. Given recent rainfall from the past few days and
pwats near climatological normals, with shear and instability
remaining weak, biggest threat with this low will be potential
for flash flooding and poor drainage flooding. There may be a
flood concern for the eastern counties outside of the coastal
plain, and will have to monitor for a flash flood issuance with
later updates. Temps will be dependent on surface low track and
associated precipitation, with highs ranging from near 90 inland
to 80s near the coast.

Long term Sunday night through Saturday
As of 310 am sat... Weak broad upper troughing with rising
heights will remain over the area into early next week. At the
surface, low pressure will track northeast across the nc coastal
plain Sunday with heavy rain possible through the afternoon. A
more amplified upper trough is forecast for late next week which
should push a stronger cold front into and possibly through the
region late in the period. This pattern will keep warm muggy
and unsettled conditions across eastern nc through late next
week.

Sun... Expecting widespread shower and thunderstorm activity to
move across the area through early afternoon as the
aforementioned low tracks across the region. The shower activity
should become scattered in the mid to late afternoon. Locally
heavy amounts are possible with pw values forecast to be around
2.5".

Mon thru fri... Typical summer pattern expected with offshore
high pressure and an inland trough producing a very warm and
muggy southerly flow across the area. Scattered mainly afternoon
and evening showers and thunderstorms are expected through mid
week. The showers and thunderstorms could become more numerous
thu and Fri as a cold front moves into the area in response to
the amplifying mid level flow. Temps will cont near to slightly
above normal with upr 80s and lower 90s for highs and muggy 70s
for lows.

Aviation 02z Sunday through Thursday
Short term through Sunday ...

as of 630 pm sat... Tricky fcst with potential st fog and
convection overnight into Sun morn. Area of ifr stratus has
formed SRN tier as precip is ending. This may briefly lift thru
evening then majority of guidance shows ifr CIGS developing
again after 06z. Shra and a few tsra will increase as well late
with ERN sites having best chc. Low clouds shld grad lift thru
sun morn and expect mainlyVFR in the aftn with much less precip
cvrg in wake of low pres.

Long term Sunday night through Wednesday ...

as of 310 am sat... Scattered to numerous showers and
thunderstorms are expected through early Sun afternoon as low
pressure tracks across the area. Scattered mainly afternoon and
evening showers and tstms expected through Mon through Wed with
brief periods of subVFR conditions. In addition, some patchy
fog st poss late night early morn with high dewpts and rather
light winds.

Marine
Short term through tonight ...

as of 945 pm Saturday... Many of the higher res mdls are showing
a period of ssw winds 20 to 25 kts over at least ERN portion of
pamlico sound late tonight into Sun aftn... Based on this will
issue a short duration SCA for these wtrs. Shra tsra have
briefly diminished but expected to ramp up overnight thru first
part of Sunday.

Prev disc... Latest surface and buoy data indicate SW ssw winds
5-15 kt across the waters with seas ranging 3 to 5 ft. Gradient
winds will relax some through later today, though low pressure
moving north through the eastern nc waters tonight will cause
southerly winds to increase to 15-25 kt with higher gusts again
possible for the outer coastal waters, bringing seas back into
the 5-7 ft range. Maintained SCA into Sunday. For the rest of
the area, winds generally in the 5-15 kt range through the
period.

Long term Sunday night through Wednesday ...

as of 310 am sat... Very difficult forecast Sun into Sun night
as an area of low pressure is forecast to track across the nc
coastal plain. Expecting a period of SCA winds and seas with
this feature sun. Significant differences in the track of the
low have led to a low confidence forecast and will forecast
winds 10-20 kt with higher gusts and seas 4-7 ft for now and
continue to monitor. Remainder of the forecast mon-wed will see
s SW flow 10-15 kt and seas 2-4 ft as atlantic high pressure
prevails across the waters.
