.SYNOPSIS...
A stationary front will remain across the region into tonight,
with periodic showers and thunderstorms continuing. A few storms
may continue to be severe, and additional instance of flash
flooding are possible. The front will drift south Saturday,
with shower and storm chances diminishing. Unsettled weather is
then expected Sunday through Tuesday with a series of crossing
disturbances.

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
KEY MESSAGES:

- Additional rounds of showers and thunderstorms into this
  evening
- Marginal Risk for severe storms this afternoon
- Ongoing flash flooding threat with training storms
---------------------------------------------------------------

Showers and thunderstorms have blossomed in the very moist
(upper 60s-lower 70s dewpoints) air mass in advance of the
quasi-stationary boundary that still lies across northern
Ohio/NW PA. A weak surface wave of low pressure has supported
the development of widespread convection. Latest PIT ACARS
sounding shows about 1000 J/kg of surface-based CAPE with about
30 knots of 0-6km shear. About 1000-1500 J/kg of MLCAPE exists
across the region. Although DCAPE values are generally in the
400-600 J/kg range, storms have still been able to develop
sufficient cores to potentially produce damaging wind and large
hail in some cases. Also, modest storm organization as a result
of the shear may still result in isolated instances of damaging
wind. SPC has maintained the Marginal (1 out of 5) risk for
this.

Otherwise, the main concern is the potential for continued flash
flooding in the very moist airmass. Precipitable water in the
1.5 to 1.6 inch range is near the top end of climatology. Have
already issued Flash Flood Warnings in locations where training
storms have produced localized 2-3 inch rainfall totals in some
cases. Storms are moving relatively slowly, with some east/west
training as storms move parallel to the flow. Outflow boundary
interactions may also create localized enhancement/backbuilding.
Flash flooding will continue to be an issue into the early
evening, on a localized basis, and the precipitable water/warm
cloud depths point to efficient rainfall.

Expect the severe weather potential to end this evening with the
loss of instability. Another shortwave trough will cross
tonight, with continued showers and storms mainly south of
Pittsburgh. This wave should help to push the front south of the
region by Saturday morning.

&&

.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
KEY MESSAGES:

- Additional showers/storms south of Pittsburgh overnight
- Decreased rain chances Saturday
- Increasing showers/storms Sunday, with a potential severe
  threat
----------------------------------------------------------------

As the shortwave departs Saturday morning, the front will be
pushed south of the region during the morning. This results in a
decrease in PoPs during the daylight hours, with most locations
from PIT on north expected to remain dry. This dry weather
continues into Saturday evening, although a few showers/storms
may linger near the Mason-Dixon Line.

Another shortwave trough will approach and cross the Upper Ohio
Valley during the late Saturday night/Sunday period, with a
surface low also approaching and crossing. This low is likely to
push the front northward through the region once again as a
warm front. Models differ a bit on the exact track of this
surface low, which could determine where the best risk of severe
weather lies. Some model soundings suggest that impressive
shear/hodograph curvature could exist across at least portions
of the region, which if paired with sufficient instability,
could suggest a larger severe threat than the current Marginal
risk advertised by SPC. Details will continue to be monitored
over the next couple of days.

The front should lift north of the region Sunday night as the
shortwave trough exits. Expect showers and thunderstorms to
taper off Sunday evening, and end overnight.

&&

.LONG TERM /MONDAY THROUGH THURSDAY/...
KEY MESSAGES:

- Unsettled weather Monday/Tuesday
- Dry and less humid weather returns Wednesday through Friday
-------------------------------------------------------------------

Ensembles agree on a 500mb closed low near the Arrowhead region
of Minnesota at 12Z Monday, with a trough extending across the
Upper Midwest. The trough advances across the Central Great
Lakes by Tuesday and then over the Upper Ohio Valley by Tuesday
night. Increasing southwest flow on Monday will provide
moisture, with ascent provided by the advancing trough and an
approaching front, producing another round of showers and
thunderstorms. Another round of severe storms is a possibility,
with ensembles indicating a chance of sufficient CAPE and deep-
layer shear. A frontal passage could create another round of
showers and storms on Tuesday.

The trough exits during the Tuesday night/Wednesday period, with
high pressure building into the region. This will result in dry
weather from Wednesday through Friday, along with a slow warming
trend.

&&

.AVIATION /15Z FRIDAY THROUGH TUESDAY/...
Currently, there are isolated showers and thunderstorms across the
area. Due to the uncertainly of where these storms will develop,
most terminals have a PROB30 and some have a TEMPO for
thunderstorms. These storms could have some isolated strong gusts of
greater than 30 knots. After the current round of storms, ceilings
will quickly lower into MVFR/IFR except south and east of PIT
(MGW/LBE).

Lingering showers/storms will diminish near 00z as cigs lower into
MVFR in western Pennsylvania and northern West Virginia. There is a
lower probability for MVFR ceilings in eastern Ohio. Restrictions
will continue overnight continue through much of Saturday morning.
Dry conditions and gradually lifting ceilings are likely to occur
across the region through Saturday afternoon.

Outlook...
Crossing low pressure will renew restriction potential
with rain on Sunday, with additional waves of rain expected Monday
into Tuesday. By Wednesday, dry conditions are expected to return to
the region.
