.WHAT HAS CHANGED...
* The NBM mean keeps trending cooler for Fri compared to its
previous iterations, and given the cold air damming regime, will
continue to favor the cooler NBM members, especially in the
Piedmont.
* Confidence is growing that the wedge will persist through Sat in
the NW Piedmont.
* There are growing concerns for isolated heavy rainfall, including
late today through tonight over the W Piedmont and Sandhills. This
threat could linger in some areas into early next week.
&&
.KEY MESSAGES...
As of 125 AM Thursday...
1) Areas of stratus and patchy fog are likely in the southeast CWA
early this morning.
2) A wedge setup will lead to cool temps Fri, particularly in the
Piedmont, and chances are increasing that it will linger into Sat in
the NW Piedmont.
2) A wet pattern starts later today, with above normal rain chances
expected through the beginning of next week. While it won`t be
raining the entire time at any given location, pockets of heavy
downpours will be possible, including late today and tonight.

.DISCUSSION...
As of 125 AM Thursday...
KEY MESSAGE 1... Areas of stratus and patchy fog are likely in the
southeast CWA early this morning.
Surface winds will be generally light through daybreak, with a flux
of higher dewpoints into our SE leading to low dewpoint depressions.
Not only is this overall pattern favorable for low stratus and/or
patchy fog, this occurrence is supported by multiple pieces of high-
res guidance, as well as by persistence, given that the SE saw low
stratus last night. The latest HREF suite appears a bit bullish,
bringing low cigs well northwest into the Hwy 1 corridor, and while
this isn`t out of the question, the highest chances for stratus/fog
should be restricted to the far SE. Any stratus/fog should lift and
mix/disperse by late morning.
KEY MESSAGE 2... A wedge setup will lead to cool temps Fri,
particularly in the Piedmont, and chances are increasing that it
will linger into Sat in the NW Piedmont.
A cold air damming event is looking like a near certainty for at
least Fri and perhaps holding on into Sat as well. Today`s front
will settle along the southern and eastern edges of the CWA late
tonight, with cool high pressure nosing in from the north as its
center shifts from the N Great Lakes across New England to just off
the Northeast coast today through Sat. Models keep this high only
modestly progressive, with slowing/anchoring confluent flow atop it,
and it remains of decent strength, around 1032 mb central pressure
at its peak, although we`re unlikely to tap into the really low
dewpoints currently at its core. Nevertheless, the combination of
cool air advection with NE flow and overrunning clouds and precip
all favor a CAD event with wedging through the Piedmont. Have kept
Fri highs closer to the NBM10Pct and mean statistical guidance,
especially across the N and W Piedmont. This yields highs in the mid-
upper 60s in the NW and near the VA border, ranging to low-mid 80s
in the far S, including mostly 70s in the Triangle. By Sat, as mid
level ridging re-asserts itself over and off the Southeast coast,
the surface/wedge front will attempt to push N and NW. But with the
center of the parent high pausing just off the Northeast coast
potentially leading to a continuation of CAA into our NW, the
retreating front may struggle to break through this stable pool. For
now, have nudged highs downward in the NW Piedmont to about a
category lower than the NBM deterministic, but further downward
adjustments may be needed in later forecasts if the wedge regime
becomes particularly stubborn.
KEY MESSAGE 3... A wet pattern starts later today, with above normal
rain chances expected through the beginning of next week. While it
won`t be raining the entire time at any given location, pockets of
heavy downpours will be possible, including late today and tonight.
As we`ve been widely advertising, we are transitioning into an
unsettled and wetter pattern with fairly high rain chances overall
for several days, although not every spot will see rain each day.
Showers and scattered storms are expected to develop along the front
across the N starting this afternoon, then settle SE with the front
tonight. Pockets of heavy rainfall are possible this afternoon
through tonight, as the latest HREF PMM shows high (50-70%) chances
for an inch in 3 hrs later today roughly N of Hwy 64, then across
much of the S and E CWA this evening into the overnight hours, all
amidst increasing PW to well above normal with strengthening SSW 850
mb flow. By Fri, the chances for pockets of heavy downpours (and
thunder) should be restricted to along and SE of the wedge front in
the afternoon through early evening, with stratiform rain more
likely further NW over the stable pool. Thereafter, as the narrow
mid level ridge weakens further, we`ll be within a weakly-perturbed
mid level SW flow from N Mexico and TX through the Mid South and S
Appalachians, with shots of mid level DPVA acting on high PW that
trends to 125-200% of normal. And once the wedge front finally lifts
to our N, we`ll stay within the warm sector for multiple days, with
persistent deep and confluent low level moist isentropic upglide at
295-305K sourced from both the Gulf and Atlantic.
This long and wavy SW mid level flow from N Mexico into the
Carolinas and the high low-level moisture flux are likely to persist
through early next week, and our rain chances are expected to remain
above normal, peaking each afternoon and evening. While this rain is
much needed with our ongoing drought conditions, the risk of high
rain rates in a short period of time raises concerns for potential
isolated flooding, especially if there is rapid runoff atop the hard
parched ground in some areas. By the middle of next week, we`ll
transition to an omega block pattern from the Bahamas up through
Ontario, sandwiched between deep lows over the Rockies and over the
Canadian Maritimes. This may push a front back down into the area,
which could prolong this wet period.

.AVIATION /11Z THURSDAY THROUGH MONDAY/...
As of 710 AM Thursday...
Patchy fog and low stratus are currently observed across parts of
the Sandhills and Coastal Plain, including at FAY. This will quickly
lift and scatter out by 13z, with mostly sunny skies and VFR
conditions everywhere the rest of the morning.
Then an approaching backdoor cold front and area of low pressure
will favor the development of scattered showers and storms this
afternoon and evening. Storms are expected to develop upstream in
western NC and VA, slowly advancing SSE along storm outflows. High-
res guidance has been slowing down and indicates the greatest threat
for storms and associated sub-VFR conditions, heavy rain and gusty
winds will be across the north, from about 21-01z at INT/GSO, 23-03z
at RDU, and 00-04z at RWI. Additional showers are expected
there through the night, but they will gradually decrease in
coverage and intensity. There will also be a wind shift from mainly
light S/SE winds to gusty NE winds immediately behind the frontal
passage, particularly in the NW, before gradually decreasing
overnight. Scattered showers may reach FAY after about 03z, but
confidence in storms and heavy rain getting there is lower as
instability will be waning by then. Once the front moves through,
IFR to LIFR stratus is expected to overspread the area from north to
south during the evening and last through the overnight hours.
Outlook: Sub-VFR ceilings should persist on Friday and Saturday over
most terminals as a CAD regime looks to set up over the region.
Widespread LIFR/IFR stratus is expected again on both Friday and
Saturday nights. The best chance for ceilings lifting to VFR would
be during the daytime on Friday and Saturday in the SE (including
FAY), while INT and GSO may stay largely LIFR the entire time. While
the CAD regime will start to break down on Sunday and Monday, low
stratus will still be possible Monday morning. Daily shower/storm
chances will also be possible through early next week.
