.DISCUSSION...
As of 1232 AM Saturday...

KEY MESSAGE 1... Areas of frost will be possible Sunday morning.

Chilly high pressure over the Mid MS valley today will migrate into
the TN valley tonight. While not in the most favorable position to
support strong radiational cooling, winds should still go calm after
sunset as the pressure gradient relaxes, from NW wind gusts of 15-20
mph this afternoon to light WNW overnight. The NBM probabilities for
36 degrees or lower range from 60-90 percent across the central and
northern Piedmont into the northern Coastal Plain. This roughly
covers an area along and north of US-64, though excluding most of
the Triad and Triangle urban centers due to the urban heat island.
Regardless, a Frost Advisory may be needed tonight into Sunday
morning over these areas as lows dip into the low to middle 30s,
except upper 30s to around 40 in urban areas and the Sandhills to
southern Coastal Plain. After collaborating with neighboring WFOs,
we decided to let the day shift take a closer look before issuing
any products.


KEY MESSAGE 2... A dry stretch of weather well into the middle of
next week as temperatures gradually moderate. A pattern shift looks
to take hold late next week, though the details are still uncertain.

Northwest flow at mid-levels this weekend will support near to
slightly below normal temperatures in the low to middle 60s.
Guidance shows quasi-zonal flow taking over early to middle of next
week, which should allow for moderating temperatures ranging from
the upper 60s to low 70s. This stretch of weather is going to be dry
with limited moisture return and a lack of systems tracking through
the region.

The period from Thursday into Saturday of next week is still highly
uncertain, however is starting to indicate a prominent pattern
shift. Much of the guidance is in decent agreement that as ridging
develops across the western US mid to late week, this allows for
deep troughing to set up over the eastern US. The result is likely a
Continental Polar airmass, which could bring our true taste of late
fall. The 540-dm thickness line drops in some solutions as far south
as GA and 850-mb temperatures drop below freezing, supportive of a
widespread freeze at some point next weekend. The also interesting
aspect to the pattern is that some ensemble cluster solutions,
including some AI members, show an area of low pressure tracking
from the TN valley to off the Mid-Atlantic coast Thursday into
Saturday. Where that tracks is highly uncertain at this point, but
could bring rain to the region and possible light snow to the
Appalachians.

.AVIATION /06Z SATURDAY THROUGH WEDNESDAY/...
As of 1232 AM Saturday...

A few areas of dense fog and low stratus are currently located over
central NC. This is likely to remain a hazard over the next few
hours until winds start to pick up and drier air moves into the
region from the north, which will allow the fog/stratus to scatter
out and lift. The most likely TAF sites to be impacted remain to be
RWI, with RDU and FAY with a non-zero risk. Most sites that are
currently impacted are LIFR with sub-1SM visibilities and ceilings
between 100-400 ft. Additionally, a few hours of low-end gusts may
be possible in the morning into the afternoon, with the best chance
in the Triad. Otherwise, VFR conditions are expected to prevail.

Outlook: VFR conditions are expected through the remainder of the
TAF outlook period. A couple reinforcing cold fronts will bring wind
shifts and perhaps some gusty winds Tuesday night into Wednesday.
