Area Forecast Discussion
National Weather Service Newport/Morehead City NC
416 PM EDT Sat May 4 2024

.SYNOPSIS...
A meandering cold front will linger over the area today before
retreating northward on Sunday. Thereafter weak troughing across
the Eastern Seaboard and warm moist southerly flow will lead to
unsettled conditions through early next week. Drier conditions
are expected by mid week, but will lead to increasing heat and
humidity as ridging builds.

.NEAR TERM /TONIGHT/...
-- Changed Discussion --
As of 3 PM Saturday...Isolated showers and thunderstorms across
the region have been ongoing over the past few hours, which
have been supported by a stalled front across central NC. With
the upper ridge sliding offshore and the stalled front moving
offshore, low-level flow will become south-southeasterly and
generate stronger moisture advection. The CAMs are showing
increased shower and thunderstorm activity developing east of
HWY 17 and west of the OBX around midnight. With the increased
moisture, PWATs will go from around 1" to 1.5"+. 500-900 J/kg of
MUCAPE is suffificent to support some thunderstorms but shear
is lacking, so the overnight severe threat is low.

.SHORT TERM /SUNDAY/...
-- Changed Discussion --
As of 3 PM Saturday...Shower and thunderstorm activity will increase
from the west tomorrow afternoon with the support of a passing
shortwave and the stationary boundary lifting north as a cold
front. Chance PoPs cover the area through the morning with a
period of likelys in the afternoon for the far western edge of
the CWA. CAPE will be sufficient but shear will be lacking once
again, so thunderstorms are possible but the severe threat is
low. With an increase in cloud cover and PoPs, high temps have
been lowered by a couple of degrees. The coastal plain is
expected to reach nearly 80 while the beaches stay in the low
70s.

.LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/...
As 315 AM Sat...Unsettled weather will continue for the first
half of next week as weak troughing lingers over the East Coast
and warm moist southerly flow develops. By mid next week drier
conditions will return but will be accompanied by an increase in
heat and humidity.

Sunday through Tuesday...Winds will veer to the south Sunday and
then SW Monday and Tuesday as high pressure rebuilds offshore
through early next week. Despite this, a combination of weak
troughing inland and deep moist southerly flow will bring fairly
unsettled conditions through Tuesday. Showers and convection
will be diurnally enhanced and will target the NC coastal plain
the most with Monday and Tuesday likely having the greatest
coverage. Temperatures will be cooler but still above normal
with highs likely in the upper 70s to low 80s Sunday and Monday,
and a bit warmer Tuesday...in the low to mid 80s.

Wednesday through Friday...Drier conditions are expected mid
week as upper level riding builds back over the Southeast.
However, increasing low level thicknesses and continued
southerly flow will lead to hot and humid conditions will
afternoon highs reaching the upper 80s to low 90s inland, and
the low to mid 80s closer to the coast.

By late Thursday a potentially strong frontal system will move
towards the East Coast and more unsettled conditions are
expected through Friday.

.AVIATION /20Z SATURDAY THROUGH THURSDAY/...
-- Changed Discussion --
SHORT TERM /through Saturday night/...
As of 3 PM Saturday...Flight cats are expected to be VFR
through tomorrow morning but isolated to scattered shower and
thunderstorm chances will present sub-VFR opportunities.
Southeasterly flow will increase moisture and support heavier
showers and thunderstorms late tonight, especially east of HWY
17. Tomorrow morning, clouds will increase in coverage and CIGs
will lower with increasing shower activity from the west. TAF
sites are expected to reach MVFR CIGs around mid-day.

LONG TERM /Sunday through Wednesday/...
As of 315 AM Sat...Generally VFR conditions are expected
through mid next week, however increasingly unsettled
conditions could lead to moments of sub-VFR conditions each
afternoon/evening. Dry and mostly clear conditions expected by
Wednesday.
