Synopsis
A cold front will move into the area tonight and stall. This
front will move south of the area early next week. High pressure
builds back in by Tuesday. Another cold front will approach the
area in the middle of next week, with unsettled weather
expected to continue.

Near term until 6 pm this evening
As of 1015 am Friday... One of the main focus for today will be
the heat and humidity. As of 8am, most of eastern nc was already
80 degrees with high dewpoints in the upper 70s, even 80-81
degree. With temperatures expected to reach in the low 90s
inland and dewpoint will remain close to want we are observing
now, the area will reach heat indices between 105-109 degrees.

Therefore, heat advisory will remain in effect through 6pm
today.

Latest mesoanalysis and 12z kmhx ua sounding is showing a very
unstable atmosphere with CAPE values already 4000-4500 j kg,
li -5 to -6 and pw at 2.29 inches. The mid-upper level trof is
forecasted to break down throughout the day, but the main
forcing will be the seabreeze to help develop showers and
thunderstorms this afternoon and evening. Have made adjustments
to the pops as the latest hi-res models (hrrr & rap) have been
showing less coverage than what was previously forecasted.

Overall, expect convection to start as early as noon along the
seabreeze and then moving inland.

Prev dis... Some active convection offshore and skirting the
outer banks early this morning. Have added a small pop to
account for this morning activity. Otherwise, no major changes
to the forecast. A trough of low pressure coupled with a very
moist unstable environment today will lead to a good coverage of
showers and thunderstorms during the afternoon and evening
hours. Model forecast surface-based CAPE values will be in the
3000-3500 j kg range during peak heating this afternoon coupled
with precipitable water values of 2.2-2.3 inches will trigger
thunderstorms with gusty winds and heavy downpours. A small
portion of our far NW CWA is in the marginal threat of severe
from SPC for today, but think strong to marginally severe storms
will be possible into the evening. With temperatures into the
low mid 90s inland and upper 80s coast coupled with dewpoints
well into the 70s, have opted to issue a heat advisory for all
but carteret county and the outer banks as heat index values may
reach 105 degrees for at least a few hours during the
afternoon, prior to the onset of convection.

Short term 6 pm this evening through 6 am Saturday
As of 310 am Friday... Expect ongoing convection at the beginning
of the period to wane with loss of heating during the late
evening hours. Some patchy late night stratus or fog will be
likely in areas that received rainfall. Yet another very warm
and muggy night with lows in the mid to upper 70s.

Long term Saturday through Thursday
This weekend...

the trend toward a faster front with a drier second half of the
weekend continues. The best chance for storms this weekend will be
Saturday and with pwats still above 2", locally heavy rain is
possible. By Sunday much drier air moves into the northern 2 3 of
the area, with pwats here dropping under 1.5". Continued low chance
pops across the far south where a cold front should be moving
through with slightly higher moisture values.

Monday Tuesday... No big changes to this period of the forecast as a
cold front mentioned above washes out across our area. The biggest
impact from the front will be the much drier air, with pwats mainly
under 1.5" and even 1.0" Tuesday! Continued very low chance pops
over areas west of route 17 both afternoons but if model guidance
continues to suggest such a dry atmosphere these chances for storms
may be too high. With upper level heights above 591 dm, highs
inland will easily reach the lower 90s with mid 80s at the beaches.

Wednesday Thursday... The next front will move into nc Wednesday, and
our area late Wednesday night into Thursday. While not nearly as
moist as the past few days, moisture will increase ahead of the
front through the period. Will maintain the previous forecast of
rain chances close to 50% during this time with the passage of the
front. Temps near 90 Wednesday will slide back into the 80s Thursday
with the passage of the front. Even drier and cooler weather is
possible late next week weekend.

Aviation 14z Friday through Tuesday
Short term through 12z Saturday ...

as of 655 am Friday... As of 1240 am Friday... Not much change
from previous thinking on aviation forecast. As expected,
patches of stratus and light fog at kpgv and kiso this morning
with some shallow fog at koaj. This stratus and fog should
dissipate by mid-morning with generallyVFR conditions expected.

A much more unstable atmosphere will lead to scattered to
numerous showers and tstms after 18z at or near all of the taf
sites. Some storms will produce brief gusty winds and heavy
downpours into the evening hours before ending after 00z with
loss of heating. Some late night stratus and fog also possible
in areas that receive rainfall tonight with brief sub-vfr
conditions possible.

Long term Saturday through Tuesday ...

as of 330 am Friday... SubVFR conditions most likely Saturday and
Saturday night with the passage of a cold front, with showers and
thunderstorms likely most terminals. Beyond Saturday night, mainly
vfr weather expected through mid week.

Marine
Short term today and tonight ...

as of 1015 am Friday... No change to forecast. Latest buoy obs
are showing SW 5-15 knots and seas around 2 ft. SW winds 10-15
knots today and seas will remain around 2 feet across the
coastal waters. Gradient will tighten ahead of a cold front
tonight as SW winds increase to 10-20 knots and seas inch up to
3-4 feet.

Long term Saturday through Tuesday ...

as of 330 am Friday... Quiet boating conditions continue on the
waters through early next week. Winds southwest 5 to 15 this
weekend with seas 2 to 4 feet. Behind a cold front winds shift into
the northeast over the northern waters Monday, with light southwest
winds over the rest of the waters. Through mid week winds back
toward the south and eventually southwest but remain 5 to 15 kts. We
capped seas at 2 to 3 feet with wave watch guidance running a bit
high with winds that light.

Mhx watches warnings advisories
Nc... Heat advisory until 6 pm edt this evening for ncz029-044>047-
079>081-090>094-098.

Marine... None.
