.DISCUSSION...
Key message 1: Temperatures warm through the weekend and mostly dry
conditions expected, with the potential for brief rain showers
across the mountains Saturday.

A persistent and strong ridge out west is slow to breakdown, keeping
the southeast in a NW downstream pattern through the weekend. High
pressure at the surface and continuous WAA over the next few days is
the main feature. By Friday, a weak area of low pressure from the
north dissipates, sending an even weaker cold front toward the area.
Guidance depicts the frontal boundary barely reaching the northern
mountains before mixing out. This brings a few areas of slight
chance (15-20%) PoP on Saturday, mostly confined to the mountains.
Confidence is very low on this, but a brief shower is possible.
Nothing significant or impactful expected. With the increased
moisture from the south, dewpoints also increase, making it feel
more like Spring should. Temperatures climb over the weekend, with
mid 80s likely by Sunday.


Key message 2: Warm temperatures continue Monday followed by a cold
front and cool down Tuesday through mid week.

An anomalous ridge over the Desert Southwest will flatten and weaken
by early next week as perturbed northern stream flow becomes
established from the Pacific Northwest to the Ohio Valley. One more
warm day with highs in the upper 60s to low 80s is on tap for Monday
ahead of an advancing lead shortwave trough. This trough will send a
surface cold front across the area through the day on Monday. This
will mainly be a dry frontal passage with the better forcing for
ascent displaced farther north and an overall dearth of moisture. A
few isolated showers will be possible along the Tennessee border
where mechanical ascent is maximized, but that will be the exception
and not the rule. Temperatures cool back to near seasonal averages
behind the frontal passage on Tuesday with a weak impulse
potentially bringing a few showers to the region late Tuesday into
Wednesday. Temperatures gradually recover and warm back into the
upper 60s to low 70s by Thursday as heights rise in advance of a
deeper longwave trough ejecting out of the Rockies.

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
At KCLT and elsewhere: VFR conditions prevail through the entire TAF
period. No restrictions to vsby/cigs anticipated. Winds are light
and mostly S/SW through the evening, before becoming VRB to calm
overnight. Some sites like KCLT go VRB during the afternoon but will
keep the S direction. Winds are slow to come up Friday morning and
vary between VRB and S/SW again. Either way, winds will be light and
not be an issue during this time.

Outlook: VFR through the weekend. Possible restrictions to start the
week as a cold front may cross the area.
