.DISCUSSION...
KEY MESSAGE 1...
Another active day planned for the Upper Ohio Valley with plenty
of heat and moisture to make for robust convection. Impacts will
be similar to Friday with wet microbursts producing strong cold
pools that will allow additional storms to develop. DCAPE values
about where they were yesterday above 1000 J/KG while flow is
around 20 knots. NAM 3KM and RREFS have somewhat similar
depictions on timing and aerial extent of storm initiation over
eastern Ohio by mid afternoon then moving into western PA and
northern WV though the late afternoon and early evening hours.
Damaging wind and lightning are the primary impacts. The only
good news in the weather department will be no heat headlines
are foreseen the next seven days.

The mid level ridge continues to break down Sunday. This allows
a stronger belt of mid level winds to be overhead allowing for
increase thunderstorm activity. Not to mention, a plume of
moisture in the column as PWATS climb to near two inches. This
will introduce a flash flood threat with storms. Even though we
have been dry for several days, urban areas it doesn`t matter as
three quarters of an inch in an hour is all it takes. The
highest probability of exceeding flash flood guidance would be
far southwest PA and northern WV. That could increase in
coverage depending on what happens on Independence Day.

KEY MESSAGE 2...
Unsettled weather with a slower departure of the low pressure
Monday and now even into most of Tuesday. This will keep highs
in the 70s and lower 80s. Coverage of showers and possibly a
storm is highest Monday afternoon areawide with downpours
likely. A gradual shift to dry weather Tuesday afternoon in
eastern Ohio then moving east through the night time hours.
Wednesday sunshine and seasonal temperatures are forecast.
Southwesterly flow returns late in the week ahead of a front
later Thursday.

.AVIATION /18Z SATURDAY THROUGH THURSDAY/...
VFR conditions will be maintained through the afternoon. Showers
and thunderstorms are expected to develop by 19Z to 22Z. This
will continue through 06Z during this time. Expect some MVFR and
even some IFR/below later in the TAF period today or even into
tonight. For the overnight period, given the uncertainty of
convection, a PROB30 was used. Low cigs are possible again
tonight with fog development based on areas that received
significant rainfall. Winds will remain southwest but become
light at times.

Additional convection is anticipated by tomorrow afternoon as
well. Some instances beginning by 16Z.

Outlook...
VFR is favored through the coming week with the exception of fog
and stratus through the mornings and showers/thunderstorms
during the afternoon/early evening.
