Latest thoughts on the upcoming hot stretch and today`s rain
chances below.

.KEY MESSAGES...
1) Extreme heat is expected this week with afternoon temperatures
reaching the lower 90s in the mountains and the middle to upper 90s
in the lowlands. Heat index values will reach the upper 90s to lower
100s area-wide.

2) No washouts are anticipated this week. Isolated downpours are
expected again this afternoon, Monday afternoon in the
mountains, and potentially again next weekend.

.DISCUSSION...
KEY MESSAGE 1...

A large dome of high pressure will expand and build into the middle
Ohio Valley beginning Monday afternoon. This will flip a switch from
the cooler temperatures seen over the past several days to highs in
the upper 80s to lower 90s area-wide by Monday afternoon. High
pressure will continue to build and center itself over the middle
Ohio Valley and mid-Atlantic region during the middle of the week,
with progressively rising temperatures each day.

Given that dew points will be in the upper 60s to lower 70s each
day, heat index values are expected to range from 100 to potentially
as high as 107 west of the mountain ridges from Tuesday onward. In
addition, little relief from the heat is expected during the
overnight hours with lows expected to be from 70 to 75 degrees.

Given that this may be a long-duration extreme heat event, which is
also occurring during a holiday week, heat safety will be extremely
important. Drinking plenty of fluids, taking breaks in the air
conditioning, and frequently checking on neighbors and family will
be vital this week. In addition, applying sunscreen will also be
very important for anyone spending extended time outdoors.

KEY MESSAGE 2...

The combination of surface moisture, a nearby stationary front, and
weak energy aloft will trigger isolated downpours today with
the highest chances being across northern West Virginia and in
the mountains. Given the high PWAT air (~1.75in) and a saturated
ground from recent rainfall, there will be an isolated flooding
risk across these areas later today. The Weather Prediction
Center has placed portions of northern West Virginia in a Slight
Risk of excessive rainfall today. This potential for isolated
showers and thunderstorms will return Monday across the
mountains.

As high pressure expands from Tuesday onward, an extended period of
dry weather will build into the region. Models show that the ridge
of high pressure may slightly break down next Saturday and Sunday,
which could allow for a few weak disturbances to cross and trigger
afternoon thunderstorms. Due to uncertainty, PoPs will be limited to
20 to 40 percent for now.

.AVIATION /00Z MONDAY THROUGH FRIDAY/...

Showers will tapper off this evening. Expect dense fog to form
overnight in areas receiving rainfall today and in the river
valleys. After the fog lifts Monday morning, expect mainly VFR
conditions with some cumulus. The exception would be with some
scattered showers and thunderstorms during the afternoon in the
northern and central mountains.
