.SYNOPSIS...
High pressure will build across the region through the remainder of
the weekend, then drift offshore on Monday.

&&

.NEAR TERM /TODAY AND TONIGHT/...
As of 145 AM Sunday...

An area of low pressure will continue to move offshore early this
morning. In it`s wake, high pressure will build across the region
through early Monday.

Aloft, mid-level height rises on order of 60-70m and associated
subsidence will follow the departure of a low-amplitude shortwave
trough. Any lingering low/mid cloudiness will clear over the next
few hours, yielding mostly sunny skies through much of the day. By
late afternoon and evening, a dense veil of cirrus overspread the
area from the west.

Light northerly low-level flow will maintain seasonable to slightly
above normal temperatures. Highs will generally reach the lower to
mid 50s, with upper 40s confined to the northern coastal plain.

Intervals of broken to overcast high clouds will continue to stream
across the area overnight, with a developing area of stratus in the
lee of the southern Appalachians likely to expand eastward into the
western Piedmont towards sunrise. Low tonight will range from
mid/upper 20s NE to lower 30s elsewhere.

&&

.SHORT TERM /MONDAY AND MONDAY NIGHT/...
As of 145 AM Sunday...

Beneath quasi-zonal flow aloft, surface high pressure centered over
the Atlantic Seaboard will move offshore by Monday afternoon.
The resulting southerly return flow, most pronounced across western
NC, may support an extensive stratus deck across much of the NC
piedmont. This cloud cover could temper diurnal heating with highs
ranging from the lower/mid 50s north to upper 50s/near 60 south.

Monday night will be milder as southerly flow persists and cloud
cover lingers. Lows are expected to range from the mid 30s to around
40.

&&

.LONG TERM /TUESDAY THROUGH SATURDAY/...
As of 105 AM Sunday

* Unseasonably warm temperatures mid to late week with temperatures
  15-25 degrees above normal.

Low level southerly to southwesterly flow will allow for well above
normal temperatures for Tuesday and Wednesday with dry conditions
under a broad mid/upper sub-tropical ridge centered over the Gulf
(more zonal flow across central NC). A weak backdoor cold front will
move into the area Wednesday evening/night, then lift back as a warm
front late Thursday. Dry conditions are expected to continue as the
main energy and moisture with the cold front will stay well to the
north. Any CAA with this cold should be fairly weak and brief as
well. Thus, expect mild above normal temperatures will continue for
Thursday and Friday.

The pattern becomes more amplified by late week into the weekend,
with an area of low pressure moving into the Ohio Valley, driving a
cold front and increasing rain chances into the Mid-Atlantic region
by Friday into the weekend. There still a fair amount of uncertainty
with regard to the overall evolution of the pattern, with timing and
strength differences currently at this time range. However, this
looks to be our best chance of seeing any rain/showers during the
medium range of the forecast.

High temps from Tuesday through Friday look to be well above normal,
with highs in the 60s to low 70s, with even some mid 70s not out of
the question. The warm weather may linger into Saturday, depending
on the timing of the next front, push of cold air. Overnight lows
are expected to be in the 40s and 50s, with the coldest lows
expected Thursday morning, generally in the lower to mid 40s behind
the backdoor cold front.

&&

.AVIATION /11Z SUNDAY THROUGH THURSDAY/...
As of 620 AM Sunday...

Synoptic scale subsidence in the wake of the departing shortwave
trough will support mostly clear/sunny skies through the afternoon.
By the evening, intervals of broken to overcast high clouds will
stream across the area overnight, with a developing area of MVFR
ceilings in the lee of the southern Appalachians likely to expand
eastward into the western Piedmont terminals around sunrise Monday.

Outlook: Outside of early morning fog and or stratus, VFR conditions
are expected to dominate for much of the upcoming week.

&&

.RAH WATCHES/WARNINGS/ADVISORIES...
None.
