Synopsis
Weak high pressure will remain over the region early this morning. A
warm front will lift north over the region today. A backdoor cold
front will move southward into the area Thursday evening into
Thursday night.

Near term through tonight
As of 400 am Tuesday...

Dense fog advisory in place for all of central north carolina
through 12 pm today...

dense fog ongoing in many locations across the area. Short term
guidance is showing fog remaining in place through much of the
morning in most locations. When it does erode, it will begin to do
so from the southeast and then quickly improve to at least MVFR
levels. With bermuda high aloft and subtropical upper level ridge in
place over the western atlantic, southerly return flow will
transport warm, moist air into the region and temperatures are
expected to climb to well above normal this afternoon. How high max
temps go will largely be dependent upon how long the fog remains in
place. If longer than expected, there will be less time for
insolation and thus cooler temperatures. Will go with upper 60s in
the immediate triad with upper 70s in the far southeast which is on
pace or slightly undercutting latest MOS guidance. A few light
showers are possible this afternoon but will be isolated and short
lived at best.

Ceilings are expected to begin to go back down to ifr levels and
below after 00z with visibilities dropping as well but low stratus
will be the bigger concern overnight. Low temperatures very mild,
near 60 degrees.

Short term Wednesday and Wednesday night
As of 400 am Tuesday...

high pressure remains anchored in place just off the coast on
Wednesday and this should keep much of the forecast area dry for
most of the day. To the west, a frontal zone with several
disturbances tracking along it will stay along the appalachians, but
precipitation associated with this feature could impinge upon our
northern and western borders late in the day but will likely remain
west of the area. High temperatures will continue to march higher
with mid 70s to 80 degrees expected throughout the forecast area.

Mild temps once again for overnight lows, near 60 degrees. Another
round of fog low stratus is possible by early Thursday morning.

Long term Thursday through Monday
As of 400 am Tuesday...

unseasonably warm record temps are again expected on Thursday in
advance of a backdoor cold front propelled by a 1040+ mb surface
high building into the area from the great lakes and northeast u.S.

However, the backdoor front should remain to the north northeast of
central nc during the heat of the afternoon on Thursday. This should
yield high temps generally ranging from the mid 70s north to the
lower 80s south, with a small chance of showers (generally across
northern portions of the area).

The aforementioned backdoor front is expected to slowly shift
southward into the area very late Thursday afternoon Thursday
evening, along with the potential for some showers across northern
portions of the area.

The cold front is expected to sink southward into the area on
Thursday night, perhaps stalling loosing steam across southern
portions of the area, with the potential for some light rain drizzle
on the the cool stable side of the boundary. Thus, expect a large
spread in high temps on Friday across the area, with a high bust
potential on temps. How fast the front lifts back northward as a
warm front on Friday into Friday night is still in question. For
now, expect the a wide range of temps from north to the south across
the area on Friday, with highs near 60 late in the day north to
highs in the mid to upper 70s far south with the potential for some
light rain and drizzle in the brief cad airmass. Low temps on
Saturday morning will be warm for this time of year, in the 50s.

With the front north of the area by Saturday, warm air will flood
the area for the weekend. The next cold front is expected to
approach the area from the west on Saturday night and move into the
area on Sunday afternoon evening with increasing chances of some
isolated to scattered showers (though any good dynamics with this
system will lift well to the north of the area with the strong sub-
tropical ridge off the southeast u.S. Allowing the track of the main
surface low to pass well to the north of central nc). Expect highs
in the 70s to near 80 for the weekend, with lows in the 50s and 60s.

High temps behind the front early next week still look to be above
normal, generally in the 60s to near 70 with surface high pressure
quickly moving across the region.

Aviation 12z Tuesday through Saturday
As of 635 am Tuesday...

24 hour TAF period: one half to one quarter mile dense fog continues
across central nc. A dense fog advisory is in place for all areas
until noon today. Expect fog to remain in place at least through mid
to late morning. Visibilities will improve after that but ceilings
will remain low, coming up to potentially MVFR briefly before
falling back to ifr and lower levels after 00z Wednesday. Winds will
be out of the south southwest today at 5-10 kts with little gusting.

Long term: a warm, moist weather pattern will promote chances for
fog and low stratus the next several mornings. A cold air damming
wedge could bring adverse conditions on Friday. A stronger cold
front will cross the area on Sunday and Sunday night.
