Area Forecast Discussion
National Weather Service Wilmington NC
125 PM EDT Sun Apr 15 2018

.SYNOPSIS...
Numerous to widespread showers and thunderstorms are expected to
develop this afternoon and tonight. There is an enhanced risk for
severe thunderstorms moving from west to east across the eastern
Carolinas late today and tonight. In the wake of a cold front, dry
and cooler weather is expected Monday. As high pressure to our south
moves offshore Tuesday, temperatures will warm with above normal
temperatures expected Wednesday and Thursday. A cold front will move
across the area Thursday night. High pressure will follow Friday and
Saturday.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 1000 AM Sunday...There is an Enhanced Risk for Severe Weather
across all of northeast South Carolina and for most of southeast
North Carolina. The primary risk continues to be damaging
thunderstorm winds. However, there also remains a smaller risk for
tornadoes and large hail. The mid to upper trough will become
negatively tilted as it moves east with strong upper level support.
Strong upward vertical motion with sharp mid-level cooling and
diurnal heating will help to destabilize the atmosphere.

Showers continue to stream N across the eastern third or so of
the Forecast Area this morning. A few showers may also develop
further W this morning and through early this afternoon. The
severe weather threat is late day and this eve across the
Interstate 95 corridor and points west in association with a
bowing squall line. This squall line will continue to move east
across the remainder of the area, moving offshore within an hour or
two either side of midnight. Given the 0-6 km storm motion,
individual cells will be moving to the N at more than 50 mph.

Sounding data shows moisture and instability increasing through
the afternoon hours in warm air mass ahead of the cold front
with mixed layer CAPE around 1100 J/kg and precipitable water
values around 1.80 inches. At the same time a low level jet of
around 60 kt within 2 kft of the surface impinges on the area.
The wind profile does veer slightly from the surface through 5
kft, from SSE to SSW. The model profile is supportive of
primarily a damaging wind threat. Discrete cells that develop
just ahead of the squall line will have the potential to produce
a tornado. Wet bulb zero heights of near 10 kft also support
large hail in the strongest updrafts. Deep moisture with a Gulf
of Mexico tap will produce very high rainfall rates. This
suggests ponding water in low spots will be quite common. At
this time, we are forecasting near 1 inch to 2 inches of rain
across the area. However, we fully expect that some locations
will tally more than 2 inches and isolated 3 inch amounts are
certainly possible.

Plenty of cool and dry air will advect in from WSW to ENE
behind the front between midnight and sunrise Monday. The column
dries out quickly with precipitable water values dropping to
less than a half inch by 12z Mon. Temps will drop down into the
50s.

&&

.SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/...
As of 345 AM Sunday...a strong cold front will be well east of
the area when Monday begins. The sky cover will be decreasing at
the onset with scattered clouds expected as a west to southwest
wind blows through out the period. In the upper levels the
large upper level low over Ohio will shift to Newfoundland by
Tuesday night. The moisture profile shows only a thin layer of
moisture from 3000 to 5000 ft from Monday Morning to Monday.
Tuesday and Tuesday night look clear.

No rain is expected this period with humidities on Monday afternoon
dropping into the 30% range and slightly drier on Tuesday afternoon.

With a downslope flow and cold air advection high temperatures on
Monday will reach the middle 60s but highs will rebound some on
Tuesday with highs reaching the upper 60s to middle 70s.  Low
temperatures Monday night are expected to fall into the lower to
middle 40s with some upper 30s in colder locations north of a line
from Burgaw, NC to Florence, SC. Lows are expected to rebound into
the low to middle 50s Tuesday night.

&&

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
As of 300 AM Sunday...high pressure will give way to a quick moving
front that will cross the waters late on thursday. Southwest winds
will increase from 15 knots early Wednesday and increase to 20 to 25
knots late Wednesday night and will shift to the west to northwest
late Thursday. A small craft advisory will be possible later
Wednesday into Thursday.

&&

.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
As of 18Z...MVFR cigs likely coastal terminals early this afternoon
becoming low VFR. Low VFR cigs KFLO/KLBT through the afternoon. Have
included VCSH all terminals for the afternoon. Winds will be south
and very gusty.

Line of thunderstorms will move into KLBT/KFLO 23-00Z and the
coastal terminals 00-01Z. LLWS prior to thunderstorms likely as low
level jet moves in ahead of thunderstorms. MVFR expected with a
brief period of IFR/wind gusts to 40 kt. VFR developing a couple of
hours after onset of storms. VFR with gusty southwest winds
overnight through the end of the TAF period.

Extended outlook...VFR.

&&

.MARINE...
NEAR TERM /THROUGH TONIGHT/...
As of 1000 AM Sunday...Small Craft Advisory in effect with
severe thunderstorms expected tonight, especially later this eve
and into the first portion of the overnight hours. Showers
early in the day will be scattered. Widespread thunderstorms are
expected to reach the waters this eve. The thunderstorms will
end with the passage of a cold front toward Mon morning.

Gradient winds will increase up to 25 to 30 kt, the strongest
winds are expected this eve. Winds will decrease 20 to 25 kt by
Mon morning as S winds veer to SW and then W behind the cold
front. Seas will build to 7 to 11 ft, highest this eve and into
the overnight before beginning a slow recession on offshore
winds.

SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/...
As of 345 AM Sunday...a strong cold front will have shifted
east of the coastal waters by the beginning of the period. Winds
are expected to remain southwest to northwest during the period
and speeds will exceed small craft values through Monday night
and are expected to drop to 15 knots on Tuesday and final to 10
to 15 knots by Tuesday night. Seas are expected to be around 6
to 9 feet early morning and drop below 6 feet Monday night with
the offshore flow. A small craft advisory will continue until
overnight Monday.

With the strong offshore winds low tides are expected to fall at or
below 1 foot below normal.  The lowest values appear to be overnight
Monday.

LONG TERM /WEDNESDAY THROUGH THURSDAY/...
As of 345 AM Sunday...high pressure will give way to a quick
moving front that will cross the waters late on thursday.
Southwest winds will increase from 15 knots early Wednesday and
increase to 20 to 25 knots late Wednesday night and will shift
to the west to northwest late Thursday. A small craft advisory
will be possible later Wednesday into Thursday.
