.WHAT HAS CHANGED...
Updated Aviation Discussion.

.KEY MESSAGES...
1) Above normal to near-record high temperatures and mostly dry
conditions to continue through mid-week.
2) The next frontal system approaches the area late week,
bringing the next appreciable chance of showers and
thunderstorms
&&
.DISCUSSION...
KEY MESSAGE 1...Notably warm low-level thicknesses beneath
anomalous mid-upper level ridging will continue to support above
to well above normal temperatures across the Carolinas through
the middle of the week. While well above normal temperatures are
expected, temperatures look to stay just shy of records. It may
be close across the coastal plain, though.
Additionally, despite increasing low-level moisture, ridging
aloft should tend to suppress convective activity outside of
perhaps a rogue shower or thunderstorm where convergence is
maximized along the seabreeze (Albemarle Sound/NRN OBX
vicinity).
KEY MESSAGE 2...The mid-upper level ridge is forecast to break
down some late-week and into the weekend. This should allow a
front to drop south into the Carolinas by Thursday or Friday.
There continues to be some uncertainty regarding whether or not
the front fully makes it through ENC, whether it stalls, or
whether it lifts quickly back north as a warm front. Given the
strength of the ridge, it stands to reason that the front will
struggle to get fully through ENC, and the forecast reflects
this scenario. Then, ridging may try to make a comeback late in
the weekend, which would favor the front lifting back north as a
warm front by early next week.
Based on the above, increasing moisture and instability along
the frontal zone should support an increased risk of showers and
thunderstorms. Probabilistic guidance shows a solid risk of
0.50"- 1.00" each day from Thursday into the weekend. However,
it should be noted that those amounts will be highly dependent
on the evolution of the frontal zone. Initially when the front
drops into the area, there may be just enough flow aloft to
support some thunderstorm organization and perhaps a marginal
risk of strong to severe thunderstorms. Machine learning and
analog guidance support this potential as well. However, no one
day stands out as having a higher risk of severe thunderstorms.
Notably high PWATs along the frontal zone should support higher
rainfall rates in convection. However, notable hydro impacts
are not expected due to the recent dry stretch and ongoing
drought conditions.
&&
.AVIATION /00Z MONDAY THROUGH FRIDAY/...
VFR conditions are noted with high pressure ridge centered
offshore extending into the Mid-Atlantic this evening. Expecting
primarily VFR conditions through the period with one notable
caveat for early Mon morning.
Steady S`rly winds will gradually ease through tonight bringing
our challenge for the evening; the potential for low
stratus/ground fog. As of this update we may remain mixed enough
and there may be enough of a dewpoint depression still to
preclude any threat for ground fog/ low stratus Mon morning.
However, guidance has been a mixed bag with some guidance
showing winds decoupling and enough low level moisture remaining
trapped beneath the nocturnal inversion to support patchy
ground fog and/or a layer of sub-VFR stratus. If we do see
ground fog it would likely spread from SW to NE starting at
OAJ/EWN first between 07-09Z and then spreading to ISO/PGV and
adjacent terminals between 09-11Z. Any ground fog that does
develop would be non impactful to operations regardless. For now
have kept in line with the previous TAFs and only noted 6SM vis
and a FEW deck of IFR ceilings at all TAF sites between 08-13Z.
If ground fog does develop expect VFR conditions to quickly
return by Mon morning and persist into Mon evening with only
notable weather being the shift in winds associated with the
daily seabreeze.
Outlook: A dry seabreeze pattern looks to continue through
Wednesday. Beyond then, a frontal boundary sagging south into
ENC is expected to bring an increasing risk of SHRA, TSRA, and
sub-VFR conditions.
&&
.MARINE...
A summer-like pattern continues through the middle of the week,
with a daily building of winds to 10-20kt each afternoon and
evening as the thermal gradient tightens. This will especially
be the case for the inland rivers and sounds and the nearby
coastal waters within 20nm of the coast. This should also
support periods of 3-5ft seas.
Outlook: A frontal boundary is forecast to sag south into the
area late-week, then meander around the area through the
upcoming weekend. This leads to lower confidence regarding winds
and seas, but especially wind direction. In general, the risk
of 25kt+ winds appears low during this time. However, there will
be an increased risk of thunderstorms along the front.
