.SYNOPSIS...
High pressure will aid in quiet and predominantly dry weather
through the forecast period. A slight warming trend begins early
next week.
&&
.NEAR TERM /THROUGH THURSDAY/...
Broad area of low pressure offshore maintains northerly flow
across the region. This reinforced wedge has kept cloud cover
abundant throughout the day and temperatures have held in the
mid 70s as a result. This evening, dry northwesterly flow should
allow for some peeks of clear skies. This should keep the
diurnal range limited with lows in the mid 60s. I have increased
these lows from the previous forecast due to early and late
cloud cover. NE winds return tonight and this should allow for
clouds to develop near the inversion. Slow clearing should occur
on Thursday with highs in the low 80s with some late-day peeks
of sunshine.
&&
.SHORT TERM /THURSDAY NIGHT THROUGH FRIDAY NIGHT/...
Continued dry this period with broad sfc high pressure nosing in
from the north. Despite an upr-level trough pivoting through the
area, mid and upper levels remain quite dry, so anticipating
mainly mostly sunny/clear skies, partly cloudy near the coast
Thursday night. Temps will be slightly below normal for mid
September...lows both nights in the upr 50s to mid 60s, and
highs Friday in the low/mid 80s.
&&
.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
Not much change in the pattern for the long term period with the
region still under the influence of sfc high pressure.
Aforementioned upr-level trough pushes off the coast leaving
continued northerly dry flow aloft in its wake. Moisture will be
limited to below 800-700 mb, but even that will be meager, and
with the lack of apparent forcing mechanisms, a dry forecast
remains for the entire period. Temps start to moderate early
next week, with highs returning to around 90 degrees western
areas Monday and staying in the mid/upr 80s there through
midweek. Low/mid 80s near the coast.
&&
.AVIATION /18Z WEDNESDAY THROUGH MONDAY/...
Northerly flow and reinforced MVFR should continue this
afternoon. Coastal sites are battling with low level mixing
near the warmer ocean waters. This does indicate that the cloud
deck is thin, so some clearing should occur tonight as the depth
of the inversion is interrupted. Northerly flow becomes more NE
this evening and will introduce some low level moisture with a
strengthening inversion. Expect IFR for NC terminals and MVFR
elsewhere to start the day on Thursday. Without strong northerly
flow, VFR should gradually develop during the afternoon.
Extended Outlook... VFR. The next chance of rain and possible
flight restrictions will be Saturday into Sunday ahead of a
mostly dry cold front.
&&
.MARINE...
Through Thursday... Broad low pressure will continue to lift north
and east tonight. High pressure over the Carolinas will weaken
tonight as winds hover around 10-15 knots. NE winds become re-
established late tonight into Thursday. After the initial surge of
NE winds (15-20 knots), winds will settle to around 15 knots for
Thursday. Seas 2-4 feet.
Thursday night through Monday... No headlines anticipated attm.
Do expect NE sustained winds of 15-20 kt and seas up to 5 ft
Friday through Saturday as the sfc pressure gradient tightens
with low pressure offshore and high pressure expanding in from
the north. Improving marine conditions thereafter for Sunday and
Monday as both the offshore low pressure and inland high
pressure weaken.
&&
.TIDES/COASTAL FLOODING...
The full moon and elevated north to northeast winds will keep tides
higher than normal into the late week period. Minor coastal flooding
expected for the immediate coasts of southeast NC and northeast SC,
including the back bays and sounds and along the Intra- coastal
Waterway, will reside with the morning high tide cycles going into
the upcoming weekend. Locations along the banks of the lower Cape
Fear River from Wilmington southward can expect minor coastal
flooding with each high tide cycle through Thursday then mainly the
midday high tide cycle Friday into this weekend.
