High pressure over the Atlantic will continue through the
weekend producing record or near record highs over Eastern North
Carolina. A cold front will approach from the west Monday and
cross late Monday night or early Tuesday. High pressure will
build in behind the front Wednesday. A strong low pressure area
may affect the region late next week.
.NEAR TERM /This Afternoon/...
As of 1 PM Fri...No changes with early afternoon update.
Previous discussion...As of 1035 AM Fri...Fcst on track with no
major changes. Despite very unstable air mass in place,
subsidence in wake of morning weak short wave and building hts
will preclude convection this afternoon. Still cant rule out an
iso sea breeze shower so no higher than a 20 pop in place for
the sea breeze corridor.
Previous discussion...As of 7 am Friday... Latest sfc analysis
show a low pressure system over the Central Canada as a front
push into the Western sections of NC, but will stall and
eventually lift. A weak shortwave associated with this feature
is crossing Eastern NC based on WV. A few showers developed
during the overnight hours, but have been short-lived. Will
continue the mention of isolated showers through mid morning as
Hi-res models continue show activity. WV satellite is showing
subsidence in wake of isolated morning showers will lead to dry
conditions across Eastern NC, but Hi- res models continue to
show the possible showers along sea-breeze. Overall, it will be
mostly dry this afternoon, but an isolated showers can not be
Ridging aloft and high pressure extending from the Western
Atlantic will lead to very warm and humid conditions across E
NC today. Low level thicknesses will range btw 1406-1416 m
supporting high temperatures in the near 90 degrees inland to
low 80s along the coast. These temps will be nearing record
territory for the area (see climate section below).

cloudy skies expected. Another warm night with lows reaching
only down into the upper 60s/low 70s.
.LONG TERM /SATURDAY THROUGH FRIDAY/...
As of 330 AM Friday...Models remain in decent agreement during
period with a upper ridge indicated for weekend, then more
progressive flow leading to more unsettled weather for next

result in a warm and dry period with temps 10-15 degrees above
normal. Models continue to indicate mainly dry weather this

with the front sliding offshore late Tue with lingering shra
ending from W to E in the morning. Will continue likely POPs for
Monday night. Highs Mon will again climb well into the 80s then
cool into the 70s Tue behind the front. High pressure is
forecast to build into the area Wed with dry weather and temps
moderating into the low 80s inland. The weather for late next
week will feature a strong upper low and complex surface low
pressure which will push a couple of fronts through the
area with the potential for significant precipitation late week
and much cooler temperatures next weekend.

As of 330 AM Friday...VFR expected to prevail through Monday
morning with enough nocturnal mixing to preclude fog
development. A cold front will be moving across the area Mon
night into early Tue with better coverage of shra and storms
with periods of sub VFR conditions possible. High pressure
builds in behind the front late Tuesday.
Short Term /through Tonight/...
As 7 am Friday...Latest buoy observations are showing SW 5-15
knots and 3 to 6 ft with the highest seas over the central
waters. Expect S to SW winds 10-20 knots with seas 3 to 6 ft
