Synopsis
High pressure will move from the carolinas down to florida
today allowing temperatures to soar into the 90s. A weak
backdoor front could briefly make it into the area Saturday, but
should return north Saturday night. Unseasonably hot conditions
will continue next week.

Near term through Saturday
As of 300 am Friday... The mid and upper levels will be dominated by
dry northwest flow between a strong ridge across georgia and a
trough sweeping off the new england coastline. Our 850 mb
temperatures are expected to soar to +19c this afternoon, allowing
highs to reach 95-97 degrees for most locations. Offshore winds at
the surface should be strong enough to delay the seabreeze by
several hours, and this should easily be the hottest day so far this
year at the grand strand and CAPE fear beaches. My forecast is for
records to be tied or broken in all locations except lumberton today.

Current record highs for today Friday may 24:
wilmington 97 in 2011
florence 97 in 1994
n. Myrtle beach 90 in 1949
lumberton 98 in 2011
the trough moving off new england is supporting a sub-1000 mb
surface low that will move out into the northwestern atlantic
tonight and Saturday. A backdoor front extending well south of this
feature should reach the CAPE fear area late tonight, sliding
southwest into the grand strand area Saturday morning. East and
northeast winds behind the front will help keep temperatures 6-10
degrees cooler near the coast versus today. West of the where the
front reaches, the same hot airmass will exist and highs should
again soar well into the 90s.

While today should remain dry with no upper features or surface
boundaries to initiate deep convection, enhanced convergence along
the front tomorrow plus a slightly weaker ridge aloft could allow one
or two thunderstorms to develop across the pee dee region. Forecast
pops are no higher than 20 percent mainly near and south of florence.

Short term Saturday night through Sunday night
As of 300 am Friday... Frontal boundary both lifts north and falls
apart Saturday night. Piedmont trough develops on Sunday. Very hot
temperatures will develop even along the coast as the sea breeze
will be quite pinned, perhaps only to the immediate beaches.

Nighttime lows will be elevated some 10 degrees above climatology
similar to daytime highs.

Long term Monday through Friday
As of 300 am Friday... Impressive mid and upper ridge just to our
west to bring a prolonged period of near record heat. The low level
ridge will move from west of the area to overhead albeit very
gradually. This prevents moisture advection through much of the
boundary layer, which should preclude heat indices that will lead to
heat advisory apparent temperatures. The ridge should finally
weaken on Friday allowing a weak cold front to enter the region. The
lack of moisture advection ahead of it will unfortunately mean no
rain. Temperatures will still run above normal on Friday, just not
as hot as the preceding week.

Aviation 12z Friday through Tuesday
As of 12z... West southwest winds are expected today, with near
record high temperatures. Tonight, a weak front drops into the
region. Only weather associated with it will be a wind shift to the
northeast.

Extended outlook... ContinuedVFR conditions are expected
through the weekend as high pressure dominates. There is a
slight chance of MVFR conditions each morning from low stratus
and or fog, and also from isolated afternoon thunderstorms.

Marine
As of 300 am Friday... High pressure will sink all the way south
to florida today, allowing winds to veer westerly across the
carolina coastal waters. Winds should be just strong enough to
delay this afternoon's seabreeze by a few hours. Instead of
south southwest winds developing around noon as is typical, look
for the shift to occur during the mid afternoon hours. This
should allow temperatures to soar into the 90s at most beaches
today.

Low pressure moving off the new england coast later today should
push a backdoor cold front south across the mid-atlantic area,
reaching CAPE fear before daybreak Saturday. Winds will shift
northeast to east behind this front. There's a fair amount of model
disagreement about how strong winds will be Saturday. The best
potential for 15 knot winds appear to be north of CAPE fear, with
speeds averaging 10 kt along the grand strand.

Seas are currently 2-3 feet and should change little through
Saturday in a mix of 8-second SE swell and 4 second local wind chop.

Light onshore flow Saturday with the last vestige of frontal
boundary lifting to the north. Piedmont trough develops Sunday
and is maintained Sunday night bringing a southwesterly flow.

Very little will change in the extended period Monday into
Tuesday so winds and seas will remain in the 10-15kt 2-3 ft
range.
