Area Forecast Discussion
National Weather Service Newport/Morehead City NC
716 AM EDT Tue Aug 12 2025
.SYNOPSIS...
High pressure will strengthen offshore the next few days,
returning to a more typical summertime pattern over the
Carolinas. A weak front will approach the area late week with
high pressure building in behind it for the weekend into early
next week.
&&
.NEAR TERM /TODAY/...
Key Messages
- Periods of heavy rainfall likely again today, which could
lead to localized flooding.
As of 715 AM Tue...High pressure offshore gradually sinks Sward
through the period with midlevel ridge expanding Wward over
SECONUS leading to weak, but more defined southerly flow through
the column. This will keep moisture content high with PWATs on
the order of 2-2.25". An embedded shortwave/remnant MCV rides
the Wward extent of the midlevel ridging from the FL panhandle
through GA during the day. Patchy fog and low clouds early this
morning will grad dissipate after sunrise this morning. Sct
showers and iso tstms continue along the immediate coast this
morning. Similar to the past few days, best precip chances along
the coast this morning then transitioning inland during the
afternoon, aided by weak shortwave energy and seabreeze. Will
continue above climo pops. Main threat will again be the
potential for heavy rain which could lead to localized minor
flooding. Low level thicknesses grad build and the return to SSW
flow should allow temps to warm into the low to mid 80s.
&&
.SHORT TERM /TONIGHT/...
As of 235 AM Tue...Expect convection to wane with loss of
heating this evening, with coverage likely shifting towards the
coast and offshore. Patchy fog and low clouds will be possible
again overnight, mainly along and west of Hwy 17...with lows in
the low to mid 70s.
&&
.LONG TERM /WEDNESDAY THROUGH MONDAY/...
As of 330 AM Tuesday...
Key Messages
- Temps peaking Thursday and Friday with heat indices around
100F
- Rain, heavy at times, possible each afternoon and evening
through Friday, before drier conditions return for the
weekend
High pressure will gradually break down and move offshore
through the rest of the week, and a more typical summer pattern
will develop as the offshore trough is kicked out to sea. More
typical, isolated to scattered coverage precip chances expected
from here as ridging and subsidence strengthen. Exception may be
Wednesday PM as a weak mid-level shortwave may support more
expansive convection and Thursday as a weak front approaches the
area. Temperatures return to around to slightly above average,
and combined with increasing humidity peak heat indices hover
around 100 degrees Thursday and Friday. This weekend into Monday
E/NE flow helps pin the sea breeze closer to the coast and
ushers in a drier setup as high pressure dominates in the wake
of Thursday`s front.
&&
.AVIATION /11Z TUESDAY THROUGH SATURDAY/...
SHORT TERM /through tonight/...
As of 715 AM Tue...Patchy fog and low stratus continue across
portions of the coastal plain this morning. Expect cigs and
vsbys to gradually improve after 13z, likely returning to VFR
outside of precip. Scattered to numerous showers and storms
expected again today, with potential for sub-VFR conditions and
heavy rain. Patchy fog and low clouds will be possible again
overnight and early Wed morning.
LONG TERM /Wednesday through Saturday/...
As of 345 AM Tuesday...Isolated to scattered tstorm chances
through Friday, with best chances of more robust coverage
Wednesday and Thursday afternoon/evening. Drier conditions
expected Saturday. Threat of low stratus and some fog continues
each morning.
&&
.MARINE...
SHORT TERM /through tonight/...
As of 715 AM Tue...Latest obs show W-SE winds 5-10 kt with seas
2-3 ft. Light winds will continue through the period, generally
S-SW 10 kt or less. Scattered to numerous showers and storms
expected again today, with potential for periods of heavy rain
and lightning.
LONG TERM /Wednesday through Saturday/...
As of 4 AM Tuesday...More typical southwesterly winds as high
pressure offshore sinks Sward. Winds through the period stay at
10-15 kts and seas will hold steady at around 2-3 feet. Front
moves through Thursday, with winds becoming NE 10-15 kts behind
it for Friday into the weekend.
