area forecast discussion
national weather service newport morehead city nc
733 am edt Tue oct 22 2019

Synopsis
A cold front will push through the area late tonight. High
pressure then builds in Wednesday through Thursday night.

Another cold front approaches the area by the end of week.

Near term until 6 pm this evening
As of 7 am tue... Observations indicate that low level clouds are
beginning to scatter as improved low level mixing arrives with
the nose of the low pre-frontal low level jet. Have adjusted sky
cover accordingly, with no other significant changes needed with
the sunrise update.

Previous discussion... High amplitude troughing working into the
eastern us will work with and approaching cold front to bring
deep layer moisture advection to eastern nc today. Scattered
showers expected to spread into the area from the south through
the morning, followed by another round of scattered showers,
with the potential for some storms as well in the afternoon.

Strong to severe storms possible mainly in the afternoon as best
low level moisture convergence and modest solar insulation
brings CAPE values to near 1000-1500 j kg with >50 kt 0-6 km
shear and 300-500 m^2 s^2 0-3 km helicity present. The window
for all of these ingredients to come together is fairly narrow,
with instability waning quickly around sunset, but the potential
for a few storms producing strong gusty winds and maybe an
isolated tornado was enough to warrant an slight risk for severe
from spc. Southerly flow will allow temps to warm several
degrees and expect highs in the mid 70s to around 80.

Short term 6 pm this evening through 6 am Wednesday
As of 4 am tue... Convective activity will wane quickly with the
loss of instability after sunset. WAA and scattered to broken
clouds will linger until the front moves through late. Clearing
and CAA will result in temps cooling quickly behind the front,
with lows around 5-10 degrees below normal despite the warm
start to the night.

Long term Wednesday through Monday
As of 330 am tue... Strong high pressure will move across the
deep south and settle over the carolinas for the end of the work
week, keeping conditions dry and seasonable. Eventually the
high will move off to the northeast and make way for a system
coming out of the gulf of mexico, but long term models continue
to carry significant differences from Friday evening through the
weekend and into early next week. Therefore, a very low
confidence forecast for the back half of the long term. The gfs
solution at this time is much quicker with the arrival of a
frontal system spurred on by and upper level trough digging down
through the mississippi valley. The ECMWF solution doesn't
carry this feature and instead illustrates a more zonal pattern
in the upper levels and a continental surface high over the ohio
valley that keeps precipitation confined to the lower
mississippi valley. This results in a much later arrival time
for precipitation across eastern nc. While still favoring the
gfs solution for the time being, have gone ahead and cut pop for
the weekend to slight chance and low end chance, to give some
acknowledgement to the ec solution.

Regardless what happens at the end of the long term, the front half
will be dry and temperatures should reach the low to mid 70s in most
locations Wednesday through Friday. At night, some decent
radiational cooling could see temps inland down in the low to mid
40s on Wednesday night, but rebounding Thursday and Friday nights
back into the 50s with mid 60s along the coast. This trend of 70s
during the day and 50s and 60s at night should continue through the
end of the long term but will be dependent upon the eventual
pattern.

Aviation 12z Tuesday through Saturday
Short term through tonight ...

as of 730 am tue... Low level clouds have largely scattered out
this morning, though brief periods of MVFR remain possible into
mid-morning ahead of a subtle warm front. Showers and
thunderstorms will cross the area late morning through early
evening, with brief periods of gusty winds and sub-vfr
conditions possible. However, recent hi-res guidance runs are
trending toward less storm coverage, so have opted to handle
with just vcsh for the time being. The front will cross the
terminals late evening or overnight, and CAA developing behind
the front will bring aboutVFR conditions Wednesday morning.

Long term Wednesday through Saturday ...

as of 430 am Tuesday...VFR conditions are likely Wednesday
through Friday. Some increase in cloud cover Friday ahead of the
approaching cold front. By Saturday, some brief sub-vfr
conditions may occur in scattered showers.

Marine
Short term through tonight ...

as of 4 am tue... Moderate winds veer to southerly and become
breezy over the course of the day in response to an approaching
cold front. This cold front will cross the waters overnight,
with winds becoming northwest and remaining breezy behind the
front. Occasional gusts to 25 kt are possible mainly across the
coastal waters later today and tonight, but 15-20 kt winds
prevail during this time. Scas remain in effect mainly for the
seas, which will subside a bit this morning before building back
to to 5 to 7 feet this afternoon and tonight mainly around and
north of ocracoke inlet in mainly locally generated windswell.

Long term Wednesday through Saturday ...

as of 430 am Tuesday... Small craft advisories for rough seas
will linger into Wednesday morning as cold front exits the area.

With broad high pressure then building into the region from the
west, Wednesday through late week will feature winds at mostly
10 knots or less, approaching 15 knots closer to 20 nm
offshore, with seas 2 to no more than 4 feet with no sca
conditions expected.

Mhx watches warnings advisories
Nc... Beach hazards statement through this evening for ncz203-205.

Marine... Small craft advisory until 8 am edt Wednesday for amz152-154.

Small craft advisory from 7 pm this evening to 2 am edt

Small craft advisory until 5 am edt Wednesday for amz150.
