.KEY MESSAGES...
1. Well-above normal temperatures continue with slightly higher
humidity returning briefly on Sunday and Monday.
2. Dry and hot most of next week with no drought relief in
sight. Daily record highs could be in jeopardy Tuesday through
the end of next week, mainly east of the mountains, but confidence
on breaking records is low at this time.

.DISCUSSION...
Key message 1: Well-above normal temperatures continue with slightly
higher humidity returning briefly on Sunday and Monday.

A broad upper ridge builds into the area Sunday then flattens on
Monday. A weak frontal boundary drops south across the area this
evening then washes out on Sunday with high pressure over the area
Monday. Low clouds do move in from the NE overnight but don`t get
too far south of the I-40 corridor or west of the I-77 corridor.
This low level moisture will lead help keep dewpoints from bottoming
out on Sunday with mixing taking place into this layer. Even with
that, have RH near 25 percent for much of the area. If dewpoints are
lower, then lower RH would be more common. RH on Monday could remain
above critical levels, but that`s more uncertain given the continued
above normal temps.


Key message 2: Dry and hot most of next week with no drought relief in
sight. Daily record highs could be in jeopardy Tuesday through the
end of next week, mainly east of the mountains, but confidence on
breaking records is low at this time.

Upper ridging continues building across the Southeast through
Wednesday before gradually breaking down Thursday into Saturday as
an upper trough approaches out of the west. Meanwhile, the
southwestern periphery of a surface high centered over the western
Atlantic will remain parked over the Southeast through Saturday as a
cold front slowly approaches out of the west. This surface ridge
will keep dry conditions around for most locations with the
exception of the North Carolina mountains Friday and Saturday as
moisture well ahead of the cold front increases. However, confidence
on rain chances remains very low as global models have been
gradually pushing rain chances later in the period. Thus, NBM chance
PoPs over the mountains on Friday and Saturday appear warranted for
now. With no real wetting rain expected in the foreseeable future,
drought conditions are likely to worsen.

In addition to the lack of rainfall, the heat will gradually crank
up Tuesday through Saturday. Highs are likely to reach into the
upper 80s and lower 90s east of the mountains each afternoon
starting Wednesday. The probability of reaching the 90 degree mark
east of the mountains will continue to increase each day through
Saturday. Thus, locations east of the mountains on both Friday
afternoon and Saturday afternoon are most likely to see highs climb
into the lower 90s. At this time, confidence remains low on breaking
any record highs across the climate sites (KAVL, KGSP, and KCLT).
KAVL looks the least likely to break any daily record highs next
week with chances looking slightly better for both KGSP and KCLT.
KGSP will have roughly a 50% chance of breaking the record high on
Thursday, while KCLT will have roughly a 50% chance to break the
record high on both Wednesday and Thursday.

.AVIATION /00Z SUNDAY THROUGH THURSDAY/...
At KCLT and elsewhere: Dry and VFR across the terminals outside of
KHKY which has the potential to see MVFR cigs develop from 12Z to
16Z Sunday. Winds will go light and VRB to calm this evening into
tonight before picking up out of the NE east of the mountains around
daybreak. Winds will then gradually turn S`ly Sunday afternoon while
increasing in speed. Wind speeds will range from 5-10 kts and low-
end intermittent gusts cannot be entirely ruled out during the
afternoon hours. At this time, KAVL looks to have the best potential
to see low-end gusts develop so only have gusts mentioned at this
terminal for now. Could see BKN to OVC cirrus develop on Sunday but
limited cigs to SCT for now.

Outlook: Expect dry and VFR conditions to persist into the middle of
next week.
