area forecast discussion
national weather service wilmington nc
120 pm edt Wed apr 25 2018

Synopsis
Daytime temperatures will rise to about normal for late april
much of the upcoming week, mainly upper 70s to around 80. A
series of low pressure systems, will bring isolated showers
today, and then a better chance of rain with isolated storms
Thursday night. A drying trend is expected into the weekend
through early next week, with seasonable temperatures, as a
canadian high drops into the mid-atlantic region.

Near term through tonight
As of 3 am Wednesday... Mid-level trough will slowly cross the
area this morning and exit to the northeast this afternoon.

Lingering moisture under the mid-level cold pool coupled with
diurnal heating usually produces at least some afternoon
convection. Forecast soundings hint at mid-level subsidence
developing this afternoon in the wake of the trough. This may
prevent deeper convection from developing, but still think low
topped showers will be possible across much of the area.

Coverage will be limited, but steep low level lapse rates and
moisture below 10k ft suggest some potential, especially across
the nc counties. Along with the isolated to scattered showers,
skies will become partly to mostly cloudy after a few hours of
heating. Do not expect much, if any lightning given the
subsidence around 10k ft. Upward motion will have trouble making
it to the freezing level, let alone generating any ice. Loss of
heating will bring an end to any shower potential and allow for
clearing skies overnight. Dry cold front moves off the coast as
the period comes to an end. Temperatures above climo continue
through the period with highs in the mid to upper 70s and lows
in the mid to upper 50s.

Short term Thursday through Friday night
As of 3 am Wednesday... 'between 2 systems' begins the day
Thursday, and not a bad day with sunshine and 70s, before
clouds increase ahead of system 2. A smaller scale, but potent
short-wave will whip northward over our western frontier
Thursday night, offering a good chance of rain showers and
tstms, favored at this time near and along the i-95 lane,
significantly lesser QPF amounts near the coast.

This short-wave and attendant surface low arrive when the days
diurnal heat is about gone, and low-level winds appear only of
moderate strength. So although the system is a potent one, odds
of a severe hazard right now appear low < 5%, but any strong
showers or storms could produce 45 mph gusts, as convection
should remain mostly still be rooted, and influential to
surface conditions. Friday a day of drying with only isolated
showers and temps remaining mild as late april climate prevails.

Long term Saturday through Tuesday
As of 3 pm Tuesday... A deepening trough will exit the coast
late Saturday. After this short-wave trough clears the larger
scale trough will shift east of the united states and ridging
will become established. Warmer temperatures are on the horizon
with lower 80s by tue. The best chance of showers will be
Saturday evening with a chance of showers and maybe a rumble of
thunder.

Aviation 18z Wednesday through Sunday
As of 18z... Sct bkn clouds around 3-4k mainly northern terminals,
with sw-w winds at 10-15 kt. As heating continues this afternoon
cloud cover will likely remain broken with showers possible, most
likely at lbt ilm. Have added vcsh at ilm where confidence is
higher, otherwise have not mentioned in tafs due to anticipated
isolated coverage. Winds by this evening will decrease as directions
become wsw-wnw then become light and variable. Wind directions will
gradually veer from NE to SE during Thursday as mid-level cloud
cover begins to increase late.

Extended outlook... Tempo MVFR Thu night through sat. Otherwise
vfr.

Marine
Near term through tonight ...

as of 3 am Wednesday... Small craft advisory continues for all
zones due to seas that have been slow to subside. Southwest
flow in the 10 to 15 kt range continues through the morning.

This should allow seas across sc zones the chance to drop under
6 ft a little after daybreak. Winds start to increase in the
afternoon as gradient tightens slightly in response to weak
surface trough moving into the area. Speeds will remain under 20
kt and direction will start to become more westerly, which may
still allow for expiration of the SCA for the nc zones later
this afternoon. Westerly flow around 10 kt through the evening
and into the overnight becomes northwest late in the period as
cold front moves across the region. Front lacks any real cold
advection and speeds will be 10 kt or less as the period ends.

Short term Thursday through Friday night ...

as of 3 am Wednesday... By Thursday morning, a cold front, not
that strong, will be moving south of the waters, with 10 kt n-ne
winds. This will only be brief, as winds quickly veer to S in
response to an approaching low pressure system. The low will
move north well west of the waters, so s-sw wind is maintained
through the period. SW gusts to 20 kt ought to be expected
Friday afternoon and evening ahead of the front, which crosses
the coast prior to daybreak Saturday. No advisories expected
with this system at this time, but it will be bumpy Friday.

Long term Saturday through Sunday ...

as of 320 pm Tuesday... High pressure will build over the waters
and winds and seas are expected to be at or below 15 knots and
no advisories are expected.

Ilm watches warnings advisories
Sc... None.

Nc... None.

Marine... Small craft advisory until 6 pm edt this evening for amz250-
252.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
