Area Forecast Discussion
National Weather Service Newport/Morehead City NC
1010 PM EDT Sun Jun 17 2018

.SYNOPSIS...
An offshore high/inland trough pattern will continue through mid
week producing a hot southwest flow across the area. An upper
level disturbance will move in from the north-northwest late this
afternoon and affect the area through Monday. A weak frontal
boundary may move into northern sections Wednesday with a somewhat
stronger front pushing through the area Thursday.

&&

.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...
As of 1010 pm Sunday...Both GFS and the ECMWF have convection
over the area overnight as vort max moves south southeast on the
eastern side of the ridge. However, based on regional radar,
the GFS seems overdone over the western half of the forecast
area, while the ECMWF look more likely. Therefore have adjusted
PoPs to slight chance western half and up to 50% eastern half.
No change to temps. Muggy SW flow will keep min temps in low to
mid 70s.

&&

.SHORT TERM /6 AM MONDAY MORNING THROUGH 6 PM MONDAY/...
As of 330 PM Sunday...Shortwave energy moves SE of the area
with the upper ridge building eastward across the area and the
offshore high/inland trough surface pattern continuing. Could
see a few showers along the coast in the morning, then expect
scattered convection to develop late morning and afternoon hours
with a moist and unstable airmass persisting; PW values around
2" and CAPE around 3000 J/kg. Primary forcing is expected to be
along the sea breeze and any lingering convecting outflow
boundaries from overnight storms. Low level thicknesses increase
several meters and expect highs to be a few degrees warmer than
today, generally in the mid 90s well inland to upper 80s/lower
90s closer to the coast. Heat indices are expected to top out
around 100-105 in the afternoon.

&&

.LONG TERM /MONDAY NIGHT THROUGH SUNDAY/...
As of 245 AM Sun...Hot and humid conditions are expected this
week, and we will see the hottest temperatures of the year so
far. Highs in the mid to upper 90s, with heat indices 105-115,
are expected Tuesday and Wednesday. There will be diurnally
based scattered thunderstorms through midweek, with a more
unsettled pattern likely by the end of the week as a cold front
approaches from the north.

Monday night through Wednesday...A strong upper level ridge
will build over the lower Mississippi Valley through midweek,
leading to hot and humid conditions across Eastern NC. At the
surface, high pressure will become centered well offshore, and
ridge into the SE US, while a weak trough forms over central NC.
Increasing low level heights through Wednesday will support
high temperatures in the mid to upper 90s inland, and the upper
80s to low 90s near the coast. Tuesday and Wednesday will be the
most oppressive days, as dewpoints increase into the mid to
upper 70s, and heat indices climb into the upper 100s to low
110s. Overnight low temperatures will be very mild ranging from
the low to upper 70s. There will be scattered precip chances
everyday, thanks to daily sea breeze formation and the weak
inland trough which will develop over central NC. Have mostly
chance PoPs through this period, with the best coverage likely
Wednesday afternoon and evening.

Thursday through Saturday...A cold front will approach from the
north Thursday, and there still remains considerable model
differences with how far south it will reach. The latest ECMWF
has trended towards the GFS, showing the front pushing through
all of Eastern NC, though the ECMWF is much slower. Given the
time of year, and relative weakness of the front, think the
slower frontal passage is more valid. This scenario would
involve unsettled weather lasting Thursday through Saturday, and
have reflected this in the forecast. Have mostly chance PoPs
for the area with greater coverage during the daytime hours.
High temperatures will still be very warm, reaching the low to
mid 90s Thursday, and then the upper 80s to low 90s Friday and
Saturday. Low temps will continue to be mild, mostly in the 70s.

&&

.AVIATION /02Z MONDAY THROUGH FRIDAY/...
Short Term /through 18Z Monday/...
As of 705 PM Sunday...VFR forecast for most of period as
typical summertime offshore high/inland trough pattern will
develop. Later tonight, guidance indicates more organized
showers and storms, associated with a shortwave trough, will
cross our area from the N. As is typical, sub-VFR conditions are
likely for any sites directly impacted.

Long Term /Monday through Thursday/...
As of 300 AM Sun...VFR conditions are expected through most of
the long term, with the exception of temporary sub VFR
conditions possible in the afternoon each day due to scattered
thunderstorms.

&&

.MARINE...
Short Term /through Monday/...
As of 10 pm Sunday...Zones in good shape. No changes to make
this evening. An offshore high/inland trough pattern will
continue through the short term bringing typical diurnally
enhanced wind pattern. SW winds around 10-20 kt expected through
this evening, strongest across the Pamlico Sound and waters
south of Oregon Inlet, relax to around 10-15 kt late tonight
into Monday morning, then increase to 15-20 kt across the
central and southern waters in the afternoon. Seas expected
around 2-4 ft through the period but could see some 5 ft seas
across the central waters by late Monday afternoon.

Long Term /Monday night through Thursday/...
As of 300 AM Sun...SW Winds 15-20 kts expected to last through
Wednesday morning, then winds become SW 10-15 kts south of Cape
Hatteras, and SW 5-10 to the north through Thursday. Seas are
expected to be around 3-5 ft south of Hatteras and 2-4 ft north
through Tuesday night, then 3-4 ft south and 2-3 ft north
Wednesday and Thursday.
