Area Forecast Discussion
National Weather Service Newport/Morehead City NC
108 PM EDT Sat Jun 23 2018
.SYNOPSIS...
An inland trough/offshore high pattern will prevail over the
area today. A cold front will approach from the northwest
Sunday and move through Monday into Monday night. High pressure
will build into the area Tuesday and gradually move offshore
Wednesday.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
As of 1055 AM Saturday...no significant changes with update.
Atmosphere similar to on Friday with modified soundings
indicating CAPES near 3500 but do have 30-40 kt of shear and
some shortwave energy moving across this afternoon. Thus
expecting more coverage of convective activity late afternoon
with some potential for downburst winds. Temps look on track for
low to mid 90s.
/Previous discussion/
As of 650 AM Saturday...Removed rain chances for the next few
hours, then introducing a slight chance by late morning to
account for developing sea breeze and local mesoscale
boundaries. Greatest development will be after 18Z, peaking 21Z
to 0Z. Looking for a repeat of yesterday with temperatures and
humidity but a better chance for more organized storms with
severe weather potential. Highs again this afternoon will be in
the lower to middle 90s, with heat indices of 100 to 105. Will
continue to mention the higher heat indices in the HWO. A few
spots will touch 105, but not widespread enough to issue a heat
advisory.
SPC has upgraded our area to a marginal risk for severe weather
with the overnight update. Unlike the past few days wind
profiles shower a greater threat for severe weather with 0-6 KM
bulk shears of up to 30 kts on both the NAM and GFS, with 0-1 KM
bulk shears of 20 kts. Our likely trigger today will be the sea
breeze or a lee side trof moving through this afternoon. This
will be aided by an upper level short wave now across Central
Tennessee which will move through our northern forecast area
between 18Z and 21Z. Lapse rates up through 700 mb are steep,
and remain decent all the way up through 500 mb. With an
inverted V sounding and the shear profiles mentioned above,
damaging winds will be the main threat. The shear will also
support the potential for large hail as well and may allow some
of the storms to organize into shorter line segments that have
some longevity.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM SUNDAY/...
As of 345 AM Saturday...Convection dies down early tonight and
with enough of a gradient through the night fog is not expected,
despite the possibility of a wet ground. Lows remain mild or in
the 70s.
&&
.LONG TERM /SUNDAY THROUGH FRIDAY/...
As of 420 AM Saturday...Hot and humid SW flow is expected to
continue into Monday ahead of a moderately strong cold front
which is forecast to move into Eastern NC Monday, pushing south
of the region Monday night. High pressure with slightly cooler
and less humid conditions will then build into the area from the
north Tuesday and Wed then continue to influence the weather
while moving offshore Thursday into next weekend with temps near
normal. Broad troughing aloft will keep the threat for
convection in the forecast Sunday. The cold front will then
bring another chance for precipitation from Sunday night into
Monday evening, then much lower but not non zero chances for
mainly isolated diurnally driven showers and storms are expected
for Tuesday and Wednesday as high pressure builds into the area
and inhibits development. The period from Thursday into next
weekend will feature mainly diurnally driven convection as
southerly flow returns heat and humidity back into the area.
Sunday through Monday...Unsettled muggy weather is expected
during this period. Broad upper troughing is expected to persist
over the area Sunday aiding lift of hot/humid airmass which
will be in place across the Carolinas leading to scattered
showers and thunderstorms. The cold front will continue the
threat for showers and storms Mon/Mon evening.
Tue and Wed...The front is forecast to push south of the region
Tue as high pressure builds over the area from the north into
Wed. As is typical for this time of year, there will be enough
residual moisture and instability behind the front to warrant
low chance PoPs each day for a few mainly diurnally driven
showers or storms. Temps will be closer to normal values in the
low to mid 80s.
Thursday into next weekend...The high is forecast to continue to
influence the weather over the area as it moves offshore and
produces a southerly flow of warmer and more humid air across
Eastern NC. This will lead to scattered diurnally driven showers
and storms each day. High temps will warm into the lower 90s.
&&
.AVIATION /17Z SATURDAY THROUGH WEDNESDAY/...
Short Term /through 18Z/...
As of 108 PM Saturday...VFR through the TAF period will be the
general rule. Showers and thunderstorms expected to develop
ahead of some shortwave energy moving across our region this
afternoon with some temporary restrictions to sub-VFR possible.
Storms should diminish after dark. VFR beyond that through
tonight with winds staying high enough to prevent any fog
formation.
Long Term /Sunday through Wednesday/...
As of 420 AM Saturday...VFR conditions are expected through
most of the long term, with the exception of occasional sub VFR
conditions possible Sunday and Monday in scattered showers and
thunderstorms. Only isolated afternoon/early evening showers and
thunderstorms are expected Tue and Wed as high pressure builds
over the area.
&&
.MARINE...
Short Term /through Tonight/...
As of 1100 AM Saturday...no changes with update.
/Previous discussion/
As of 650 AM Saturday...Seas 3 to 4 feet and southwest winds 15
to 20 continue. Winds will gradually increase a few knots today
as a pressure gradient strengthens over the waters. Small craft
advisories look good, with the strongest winds over the Pamlico
Sound and central waters. Seas of 3 to 4 feet now will increase
to 4 to 5 feet this afternoon and tonight, with a few 6 footers
outer central waters. Winds remain out of the southwest 15 to
20 plus, with gusts to 25 knots.
Long Term /Sunday through Wednesday/...
As of 420 AM Saturday...Small Craft Advisory conditions will
continue across the waters through Sunday night with prefrontal
SW flow of 20-25 kt. Winds Monday shift to NE and diminish to 10
to 15 kt behind the front continuing into Tue as high pressure
builds over the waters from the north. The flow is forecast to
veer to SE 10-15 kt Wed. Seas build to 4 to 7 ft into Sun night,
subsiding to 3 to 5 ft Mon and 2 to 4 ft Tue and Wed.
