.SYNOPSIS...
A stationary front will remain across the region today and
tonight, and will provide the focus for periodic showers and
thunderstorms. Some storms could be severe and could contain
locally heavy rain this afternoon and evening. 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 today
- Marginal Risk for severe storms this afternoon
- Locally heavy rainfall possible
---------------------------------------------------------------

A stationary front was analyzed across northern Ohio into NW
PA. This front will remain quasi stationary today with the flow
aloft parallel to the front. Individual vort maxes embedded in
the westerly flow aloft will provide additional ascent for
showers and thunderstorms today. One shortwave is expected to
cross the area this morning, bringing an increase in showers
and a few storms. These showers and isolated thunderstorms have
recently developed across Ohio as this wave approaches.

A surface wave is expected to develop along the front this
afternoon, as it tracks across the Upper Ohio Valley region.
This should bring another increase in showers and thunderstorms.
Building diurnal instability is progged through the day, with
mean MU CAPE values ranging from 1000-1500 j/kg. An increase in
the mid and upper level flow should result in more shear than
yesterday, with 0-6km values from 30-40kt. This could result in
a few organized storms across the region, with a damaging wind
potential. The Storm Prediction Center has included most of the
area in a Marginal Risk, or level 1 out of 5, for severe storms
this afternoon and early evening.

PWATS remain elevated at around 1.5 inches. Locally heavy
rainfall is possible, though storm motion should be faster than
today. Still, if any area receives multiple storms, localized
flash flooding will be possible. Will include this potential in
the Hazardous Weather Outlook and add a mention of locally heavy
rain to the forecast grids. The threat appears to be too
localized for a flash flood watch at this time.

.SHORT TERM /6 PM THIS EVENING THROUGH SUNDAY NIGHT/...
KEY MESSAGES:

- Marginal Risk for severe storms early this evening
- Locally heavy rainfall possible especially this evening
- Decreased rain chances Saturday
- Increasing showers/storms Sunday
----------------------------------------------------------------

The surface wave will continue to track east along the front
early this evening. Showers and thunderstorms will continue,
along with a marginal potential for damaging wind gusts and
locally heavy rain. MU CAPE quickly diminishes this evening
after the passage of the surface wave. Expect the severe weather
potential to end early this evening with the loss of surface
based instability, though elevated instability could still
support a few storms overnight.

Another crossing shortwave trough is progged for a Friday night
passage, with showers and a few thunderstorms continuing. The
resulting WNW flow behind this trough should help to push the
front south of the region on Saturday. Expect an overall
decrease in POPS from N-S, with most areas from PIT northward
staying dry. Areas to the south will still be in closer
proximity to the front, with shower and isolated thunderstorm
chances continuing.

Saturday evening should be dry with the front to our south.
Another shortwave trough is expected to advance out of the
Midwest Saturday night, along with a developing surface low. The
trough will cross th Upper Ohio Valley region on Sunday, as the
surface low tracks across the Great Lakes, pulling the front
back north as a warm front. Increasing shower and thunderstorm
chances are expected again during the day with the approach and
passage of the shortwave trough and warm front. There is also a
potential for severe storms Sunday with increasing shear and
instability, though details will 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 Tuesday
- Dry and less humid weather returns Wednesday and Thursday
-------------------------------------------------------------------

Model ensembles indicate a deep trough across the Upper Midwest
on Monday, advancing eastward through the day. Expect shower and
thunderstorm chances to increase again Monday with moisture and
ascent overspreading the region in SW flow ahead of the trough.
The highest shower and thunderstorm chances are expected on
Tuesday, as the trough axis crosses the region.

The trough is expected to exit the region on Wednesday, as
surface high pressure begins to build in. This should return dry
weather to the region Wednesday and Thursday.

Temperatures should average near seasonable levels through
midweek, before rising 500 mb heights and a building ridge
return readings to above average by Thursday.

&&

.AVIATION /10Z FRIDAY THROUGH TUESDAY/...
Iso/Sct light showers continue early this morning. Widespread
fog is not anticipated given cloud cover, though pockets of fog
have been observed. A few terminals (e.g. BVI/FKL) will likely
bounce up and down through the remainder of the overnight.

The next wave will reinvigorate showers near 12z. Cigs will
quickly lower into MVFR/IFR except south and east of PIT
(MGW/LBE). Showers will become spottier again by midday with
gradual cig improvement.

Scattered showers and thunderstorms are likely after 18z Friday
as convective temperatures are reached. Covered this threat with
PROB30s given scattered nature of potential thunderstorms.
Lingering showers/storms will diminish near 00z as cigs lower
into IFR areawide. Restrictions will continue through much of
Saturday morning.

Outlook... Widespread MVFR/IFR ceiling restrictions are expected
into Saturday as a series of shortwaves brings continued shower
and thunderstorm chances. These are likely to lift Saturday
afternoon with brief drying. Crossing low pressure will renew
restriction potential with rain on Sunday, with additional waves
of rain expected Monday into Tuesday.
