.DISCUSSION...
KEY MESSAGE 1...Shower and storm coverage lessens into early
week. Still a few strong storms/heavy downpours this afternoon
mainly in NC into southside VA.

Debris clouds from upstream overnight convection has put a lid
on instability in the mountains and north of the VA/NC border.
Some sun is allowing for SBCAPEs to reach 1000-1500 J/kg in the
south. This would be the area to watch for any strong storm
development. So far radar trends are mainly showing lower topped
heavy rainers with limited if any lightning. Better severe
convective potential will be south of I-40 in NC toward the SC
border.

Will have to watch for localized flooding as PWATS running from
1.7 to 2 inches west to east, especially in training cells.

Showers start to fade as front works south tonight but
atmosphere remains highly moist, so cannot rule out isolated
showers, or even drizzle along the Blue Ridge.

Monday looks like less coverage but another upstream shortwave
on the east side of the ridge could lead to widely scattered
storms in the afternoon.

KEY MESSAGE 2...Hot and humid conditions will occur during the
latter half of this week.

A broad upper level ridge should build northeastward towards
the Ohio River Valley between Monday and Wednesday. This ridge
could become centered overhead by Thursday and Friday. While
chances of showers and thunderstorms should lessen due to
capping aloft, the bigger impact will be the increasing heat and
humidity. Temperatures should jump notably after Tuesday with
highs in the 90s for most locations and even a few lower 100s
east of the Blue Ridge for the remainder of this week. Heat
indices could reach up to 105 degrees across the Piedmont. There
may be upper level troughing across southeastern Canada that
could start to gradually weaken the ridge towards the end of
this week, but Independence Day looks to stay hot and humid.
Make sure to have plenty of water and sunscreen, and check your
air conditioners to ensure that they are working properly.

.AVIATION /00Z MONDAY THROUGH FRIDAY/...
Shower activity should wane as we progress through the evening
and early overnight hours. However, for much of the region
overnight and into early Monday morning, we are expecting sub-
VFR cigs and vsbys with stratus and mist/fog. Conditions improve
to VFR for the entire area by the late morning.

Winds will be light and variable or calm through the night, and
stay that way, or trend light east, through the day Monday.

Isolated showers and storms will be possible generally along a
KHSP to KMWK line tomorrow afternoon/evening. Some of the
stronger ones could yield some brief and localized sub-VFR
conditions.

EXTENDED AVIATION OUTLOOK...
Cannot rule out some isolated showers/storms the rest of the
week, but the upcoming week will feature high pressure and
mainly VFR conditions, outside any late night fog.

.RNK WATCHES/WARNINGS/ADVISORIES...
