Synopsis
Weak high pressure moves off the coast tonight. A cold front
will move into the area this weekend 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 through tonight
As of 1240 am Friday... A very humid, but rain-free night over
eastern nc. Latest hrrr does indicate a few showers or possible storms
along the immediate south coast overnight and will continue
with a small pop there. Patchy fog will be possible, mainly
coastal plains where some precipitation fell earlier today. No
major changes to the ongoing forecast at this time.

Short term Saturday through 6 pm today
As of 330 pm Thursday... The warm front mentioned above moves
into our area Friday, with a better chance for more of the area
to see scattered storms. If you take a look at what is happening
to our southwest today near wilmington, this should give us a
good snap shot for our weather Friday. As dewpoints creep into
the mid to upper 70s for more of the area, and highs push the
lower 90s, head indices above 100 are likely. We will continue
to mention the possibility of heat indices near 105 in our hwo.

The shift tonight may have to consider a heat advisory if
confidence grows that we will exceed 105 for a few hours.

Mlcapes around 2,000 j kg and lifted indices around -5 support
the chance for some severe storms Friday afternoon. Spc
continues our area in a general thunderstorm risk but soundings
do show slightly better shear and wind fields than today, with
the warm front moving through.

Long term tonight through Thursday
As of 330 pm Thursday... Unsettled conditions will continue
Friday night and Saturday with the approach of a cold front in
the area, before drier conditions begin Sunday into early next
week. A significant shortwave will drop down mid week into the
area leading to better rain chances by mid week.

Friday night through Saturday... The approaching cold front
will continue to bring an increase of low level moisture and
instability across the area Friday night and Saturday... Leading
to showers and thunderstorms. Instability will be especially
high for Saturday with forecast CAPE values in excess of 3000
j kg and LI value around -9 during peak heating. Will have high
chance pops Friday night and Saturday. A decent mid-level
shortwave may also keep storms going over the northern tier
Friday night and will have high chance pops north and along the
coast Friday night. Overnight lows are expect to range mid upper
70s inland to around 80 degrees along obx. Saturday will be
warm and humid with highs near 90 inland and mid 80s along the
coast.

Sunday through Tuesday... Models continue to show a drier
trends with pops starting Sunday through Tuesday as a mid-level
ridge expands across the area leading to hot temperatures and
less convection as precipitable water values drop to 1.6 inches
or less for a couple of days. There may be a few storms along
the sea breeze, but pops will be below climo through this
period. Expect high temps near 90 degrees inland and around mid
80 along the coast. Overnight lows in the low 70s inland to
mid upper 70s along the coast.

Wednesday and Thursday... The mid-upper level ridge starts to
break down as a shortwave drops down from the great lake region
and into the middle-atlantic southeast region on Wednesday, then
cold front approaches the area towards the end of the period.

This will lead to an increase chances for showers and
thunderstorms starting Wednesday into the latter part of next
week. Expect high temps in the mid upper 80s inland and mid
80s along the coast. Overnight lows in the low 70s inland to mid
70s along the coast.

Aviation 06z Friday through Tuesday
Short term through 06z Saturday ...

as of 1240 am Friday... Anticipate some patches of stratus and
fog at kpgv and kiso where precipitation occurred earlier today.

This lines up well with previous forecast and no major changes
made. 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.

Long term Friday night through Tuesday ...

as of 330 pm Thursday...VFR conditions will dominate most of
the period, except for Friday night and Saturday as sub-vfr
conditions will be possible under showers and thunderstorms
along with locally heavy downpours. A drier pattern will start
Sunday and improve further through the end of the period. Some
early morning fog and patchy stratus may also be possible in
areas that receive decent rainfall through the period.

Marine
Short term through Friday ...

as of 1245 am Friday... Quiet conditions continue on the coastal
waters and sounds with S winds 5-15 knots and seas around 2
feet. A warm front will start to lift north through the waters
overnight into Friday. Winds will then become more SW at 10-20
knots for Friday. Seas will build to 3 to possibly 4 feet on
Friday.

Long term Friday night through Tuesday ...

as of 330 pm Thursday... A cold front will approach the area
from the west, tightening the pressure gradient and increasing
winds Friday night SW 15-20 knots and then becoming SW 10-15
knots Saturday. Seas are expected to slightly build Friday night
in response with the increase winds, expect 3-4 ft with possible
5 ft over the outer waters. The cold front is expected to
dissipate over eastern nc Sunday, allowing winds to remain S sw
around 10 knots or less through the period. Seas will start to
subside Saturday night and expect seas to generally be 2-3 ft
through Tuesday.

Mhx watches warnings advisories
Nc... None.
