.DISCUSSION...
Key message 1: Relatively warm late summer weather will persist
through the week, with low risk for significant weather.

The weather is still looking fairly quiet thru the week with a
fairly low chance for any high impact weather. We have a back-door 
cold front moving down from the north later this afternoon/evening
which could help produce a few showers, but that's about it.  

An upper ridge builds eastward over our region over the next 24 
to 48 hrs and helps keep the convective environment generally 
unfavorable/suppressed with most of the area remaining dry. With
the fropa later in the day today, we get one more hot day with 
high temps 5 to 10 degrees above normal. We still have the poten-
tial for some weak, dry, cold air damming as broad surface high 
pressure moves from New England on Tuesday to a position off the 
coast of New England and the Maritime Provinces on Wed. There 
could be some shallow moisture within the ELY low-level flow on 
Tues that helps keep temperatures around normal with some increase 
in low clouds, but there will be minimal forcing for precip and 
any appreciable moisture doesn't hang around for long. This should 
result in temps warming back above normal on Wed, with highs back 
in the lower 90s east of the mtns by the end of the week. As the 
airmass modifies and warms, we expect a return of high elevation 
scattered diurnal showers and thunderstorms from Thurs thru next 
weekend.

.AVIATION /00Z TUESDAY THROUGH SATURDAY/...
At KCLT and elsewhere: The forecast stratus off VFR at all terminals 
as a backdoor cold front approaches from the northeast. As the front 
pushes into the area overnight, a plume of moisture will pool ahead 
of the boundary and help to promote the development of at least 
isolated showers along with low stratus. TEMPO groups have 
introduced to account for any associated restrictions. Showers 
should dissipate within several hours of sunrise along with lifting 
and scattering of any low stratus. This will bring a return to VFR 
conditions by mid to late morning. Winds will be out of the 
northeast and could be as high as 9-12kts with a few isolated low-
end gusts not out of the question. Winds will relax through the 
afternoon behind the front.

Outlook: Mostly dry conditions are expected to persist through the 
middle of the week. Shower chances and associated restrictions 
increase later in the week. Mountain valley fog and low stratus is 
possible each morning through the week.
