.WHAT HAS CHANGED...
A Dense Fog Advisory has been raised over the coastal waters
from Cape Fear NC through South Santee River SC due as dense fog
is evident from beach cameras and satellite imagery. This fog
should tend to mix out during the midday to early afternoon as
daytime heating helps to increase winds near the shore.

&&

.KEY MESSAGES...
1)Intermittent sea fog will continue to impact the coastal
waters and immediate coastline through Wednesday.

2)The warmth peaks Wednesday before a cold front arrives on
Thursday.

.DISCUSSION...
KEY MESSAGE 1...Intermittent sea fog will continue to impact
the coastal waters and immediate coastline through Wednesday.

KEY MESSAGE 1 DESCRIPTION...
Persistent advection of warm, moist air over the waters will
continue to produce intermittent sea fog, dense at times,
through mid-week. Best chance will be overnight into midday. Sea
fog will continue to impact the immediate coastline as well,
especially during morning hours. Strong cold front early
Thursday will finally bring an end to this extended stretch of
on and off sea fog.

KEY MESSAGE 2...The warmth peaks Wednesday before a cold front
arrives on Thursday.

KEY MESSAGE 2 DESCRIPTION...
As has been the case for several days now a summer-like Bermuda
High pattern will keep temperatures well above normal through
the mid week period. Wednesday gets a small prefrontal
bolstering of the WAA and inland locations will take a run at
record highs, listed below. The marine layer will keep coastal
climate sites records safe as SSTs remain in the low 50s. A
strong cold front arrives Thursday bringing several rounds of
showers and thunderstorms. Extrapolating the SPC outlooks it`s
easy to see that the front will bring a small but non-zero
chance for strong to severe thunderstorms. This is not
surprising given both the vigor of the boundary and the ample
warmth and moisture in place ahead of it passage. The cooldown
back to normal temperatures looks to be limited to Thursday
night through Friday night before the post-frontal high moves
offshore and we get back into return flow.

Inland record highs for March 11:
FLO 86 set in 2015
LBT 87 from 1925

.AVIATION /13Z MONDAY THROUGH FRIDAY/...
Widespread fog will continue for the next couple of hours,
possibly lifting to stratus by mid morning across the area.
Restrictions are expected for all terminals, slightly longer at
our Grand Strand terminals where sea fog may persist slightly
longer into the late morning. By early afternoon, all terminals
should return to VFR. VFR should persist through the afternoon
and much of this evening. Lower dew points are expected tonight
which should keep the threat of fog lower than previous nights,
but sea fog may complicate the forecast along the Grand Strand.

Extended Forecast... VFR conditions are expected for much of the
extended period, but periods of fog could bring late night/early
morning restrictions. Sea fog could advect into the Grand Strand
terminals at times during this week.&&

&&

.MARINE...
Through Tonight... Showers and storms have kept most of the
nearshore sea fog from redeveloping. However, as showers move
farther offshore and light southerly flow returns this morning sea
fog may redevelop prior to sunrise. A nearshore sea breeze may break
up existing sea fog during the late morning and afternoon, but
little change in dew points and light winds tonight could see it
redevelop through early Tuesday.

Tuesday through Friday... The Bermuda High continues to be the
dominant weather-maker over both land and sea. For the marine
environment this means more southwesterly flow generating a 2-3
ft wind with a southeasterly swell. Big changes come with a
strong cold front Thursday that will sharply turn winds through
W, NW, and eventually NE with sustained SCA speeds and gale-
force gusts. Seas will also build to advisory levels. It`s a
quick shot though so headlines may come down as early as
Thursday night in a very progressive surface pattern.
