Area Forecast Discussion
National Weather Service Newport/Morehead City NC
935 AM EDT WED MAY 25 2016

.SYNOPSIS...
High pressure will extend over the area from offshore through
Friday night producing above normal temperatures. Weak low
pressure will approach from the south Saturday through Tuesday.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
As of 930 AM Wednesday...No changes needed on update. Above
normal temps in store as the the H5 ridge builds into the region.
Given this and the Bermuda High in place, this will translate into
increasing thickness under sunny skies and warm SW flow allowing
temps to climb into the mid/upper 80s.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM THURSDAY/...
As of 3 AM Wednesday...Surface ridge remains to the south tonight
with a light and warm SW flow continuing across ENC. Skies will
remain clear with temperatures falling into the lower 60s inland
to the mid and upper 60s on the coast.

&&

.LONG TERM /THURSDAY THROUGH TUESDAY/...
As of 330 AM Wednesday...No significant changes during forecast
period with this issuance. Latest models remain in decent
agreement with warm and dry conditions through Friday, then
subtropical moisture affecting area rest of period with mid level
weakness and surface reflection lifting N-NW toward SE U.S. coast.

Thursday through Friday night...Rising upper level heights
coupled with surface high pressure lingering off the Carolina
coast will lead to warm and dry conditions through the remainder
of the work week. Numerical guidance shows high temperatures well
into the 80s Thursday with lower 80s Outer Banks. There is a
subtle difference on Friday with models indicating low level
thicknesses 5-10 meters lower than Thursday, which is reflected in
MOS guidance with max temps a couple of degrees cooler. Adjusted
max temp forecast accordingly with mainly mid 80s inland and
around 80 beaches.

Saturday through Tuesday...00Z models remain in decent agreement
with gradual pattern change that will result in upper ridge along
east coast moving east. In turn, mid level weakness with sub-
tropical moisture east of Bahamas will be be drawn NW toward SE
U.S. coast. Models continue to indicate weak surface low moving
toward GA/SC with some concern for tropical/subtropical
development but models generally keep it south of Eastern NC
during period. Main result for area will be increasing subtropical
moisture with deepening SE-S flow with threat of at least
scattered coverage of showers/thunderstorms through period. Kept
POPs in chance range for now. With the increased cloud coverage,
expecting a small diurnal temperature variation through this
period with lows generally upper 60s to around 70 and highs around
80 degrees.

&&

.AVIATION /14Z WEDNESDAY THROUGH SUNDAY/...
Short Term /Through 06Z Thursday/...
As of 3 AM Wednesday...VFR conditions expected through the short
term with mostly clear skies. Winds will be SW less than 10 knots
today becoming light SW tonight. Low level moisture remains
limited so will leave patchy fog out of the TAF site forecasts for
tonight.

Long Term /Thursday through Sunday/...
As of 330 AM Wednesday...High pressure along the southeast coast
coupled with ridging aloft will lead to VFR conditions with mostly
clear skies Wednesday night through Friday/Friday night. As
usual...there could be brief patches of early morning fog, but
overall impact will be minimal. Longer range guidance still
indicates low pressure forming off the GA/SC coast by the weekend
with an increase in low-level moisture and precipitation for
Saturday and Sunday...with sub-VFR conditions possible with
convective activity.

&&

.MARINE...
Short Term /Through tonight/...
As of 930 AM Wednesday...No changes. Pleasant boating conditions
through the period with high pressure off the southeast coast.
Expect SW winds 5-15 knots with seas 2-3 feet continuing tonight.

Long Term /Thursday through Sunday/...
As of 330 AM Wednesday...High pressure at the surface and aloft
will help maintain S/SW at generally less than 15 knots with seas
around 2 feet Thursday and Thursday night. Good agreement with
longer range models showing surface low pressure forming off the
GA/SC coast and meandering to our south into early next week with
very weak mid-level flow. Result will be persistent E-SE winds
around 10 KT across waters with seas building to 4-5 FT.

&&

.MHX WATCHES/WARNINGS/ADVISORIES...
NC...None.
MARINE...None.
