.WHAT HAS CHANGED...
Aviation updated.

.KEY MESSAGES...
1) Heat risk increases to dangerous levels this week into the
holiday weekend. For Wednesday through Sunday, Extreme Heat
Watches and/or Heat Advisories will likely be needed.

2) Isolated to widely scattered daily afternoon and evening
showers and thunderstorms possible each day this work week,
mainly for the mountains. More widespread showers and storms are
expected over the weekend.

.DISCUSSION...
KEY MESSAGE 1...Heat risk increases to dangerous levels this
week into the holiday weekend. For Wednesday through Sunday
Extreme Heat Watches and/or Heat Advisories will likely be
needed.

We remain on the periphery of strong mid level ridging
stretching from Gulfport, AL north into central Canada through
tomorrow. After that, the ridge essentially parks overhead and
will be the main factor in building warmth and humidity.
Maximum and minimum temperatures will be well above normal,
with the ECMWF extreme forecast index showing these near the
90th percentile relative to reanalysis climatology. NAEFS also
indicates temperatures anomalies between 3 and 4 standard
deviations above normal, centered over the Blue Ridge. This
lends high confidence in a significant heat wave occurring.

Concerns about the forecast: afternoon showers and storms as
well as possible cloud debris from any summertime overnight MCSs
could keep temperatures a bit lower than forecast. In addition,
dew points should mix out well each afternoon, so humidities
will not be overly oppressive. That said, a drier heat is still
dangerous, and those with outdoor plans, including holiday
festivities and recreational activities, should prepare for
several days of elevated heat risk. Stay hydrated, take frequent
breaks in air conditioned or shaded areas, and never leave
children or pets unattended in vehicles.


KEY MESSAGE 2...Isolated to widely scattered daily afternoon and
evening showers and thunderstorms possible this work week,
mainly for the mountains. More widespread showers and storms are
expected over the weekend.

The aforementioned ridging will also work to keep a lid on most
shower and thunderstorm activity. However, each day through the
work week expect isolated to widely scattered convection to
develop, mainly over the mountains. These cells will not amount
to much and will have a hard time trying to grow vertically, so
severe potential looks quite low. Main concern would be an
isolated tree down and localized heavy rain.

By the weekend, the ridge will partially break down. This will
allow more short wave energy to cross the forecast area,
sparking numerous showers and storms for the Independence Day
weekend. We will likely see pockets of instability both days,
leading to more of a concern for damaging winds and flash
flooding.

&&

.AVIATION /00Z TUESDAY THROUGH SATURDAY/...
Showers have dissipated across the vast majority of the region.
One lingering thunderstorm continues between KLWB and KROA,
heading south towards KBCB. VFR conditions prevail, but brief
and localized sub-VFR conditions are expected with the
thunderstorm, along with gusty and variable wind.

Overnight, cigs and vsbys will trend to mainly IFR/MVFR across
the mountains and foothill region. Areas along and east of a
KMTV to KLYH line will likely remain VFR.

Any sub-VFR conditions will improve to VFR by the late morning.
Winds will generally be light and variable or calm overnight,
with a light southeast winds for many areas on Tuesday.

EXTENDED AVIATION OUTLOOK... Diurnal showers and thunderstorms
are expected mainly across the mountains through the workweek.
Mountain valley fog/low stratus will be possible each morning.

.RNK WATCHES/WARNINGS/ADVISORIES...
VA...None.
NC...None.
WV...None.
