Area Forecast Discussion
National Weather Service Pittsburgh PA
231 PM EDT Fri Sep 6 2024

.SYNOPSIS...
A fast moving cold front will increase the risk for showers and
storms later this afternoon and into the overnight hours. Much
cooler on Saturday. Sunday looks to be the start of another
extended dry period.

&&

.NEAR TERM /THROUGH TONIGHT/...
KEY MESSAGES:

- Showers and storms looking likely late this afternoon and
  evening.
-Rain coverage and intensity lessens tonight.
----------------------------------------------------------------

A shortwave trough will continue to traverse the region this
afternoon and into the evening. the first wave is crossing
western PA/eastern OH now. The clearing earlier in the day has
allowed for enough instability to pop some showers and weak
thunderstorms.

The actual cold front is crossing central OH currently. The 12Z
sounding from PIT showed a decent cap at about 600MB. Thus, this
will likely take the forcing of the front itself for strong to
severe convection and the main concern will be damaging winds
given the 1000 to 1200 DCAPES through the afternoon and evening.
As currently, storms are topping out at 15 to 20 KFT and are
less impressive in a capped environment ahead of the front.

SPC continues to show a marginal risk for severe storms across
a portion of the region this afternoon and evening. Rain
chances will dwindle once the front clears to the east, which
should be sometime late tonight after 06Z or early Saturday.

&&

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

-Showers should end Saturday morning.
-Cloudy and much cooler Saturday.
-Increased sunshine Sunday, but temperatures remain seasonably
 cool
-------------------------------------------------------------------

During the day on Saturday, as the rest of the upper trough
passes through the area, lingering showers cannot be completely
ruled out Saturday morning behind the front, due to the trough
axis swinging through and the strong cold air advection. The
cold air advection, and northwest flow aloft, should mean plenty
of clouds on Saturday. High temperatures Saturday look to be 10
to 15 degrees below normal.

A majority of ensembles have the upper low slowly drifting
northeast on Sunday, allowing a reduction in cloud cover,
although flow will advect air sourced from northern Canada,
leaving temperatures around 10 degrees below average.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
KEY MESSAGES:

- Dry weather and a warming trend next week.
-------------------------------------------------------------------

Concerning the blocking low in the eastern Great
Lakes/Northeast, some ensembles have the low slower to depart,
others are a bit more progressive. These timing differences are
leading to some temperature uncertainty on Monday, but by
Tuesday, almost all ensembles have the upper low out of the way
and a ridge building in. This translates to high confidence in
highs in the 80s for most by the middle part of next week with
continued dry weather.

&&

.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
VFR is expected for most of the day ahead of an approaching cold
front. Scattered cumulus will continue, with isolated
showers/storms ahead along a boundary ahead of an approaching
cold front. Shower and thunderstorm chances will increase late
in the day and this evening as the front crosses the region.
Timed in the showers/storms with an arrival around 23Z at PIT,
and included a TEMPO for thunderstorms for the most likely time
of occurrence.

0-6km shear increases to around 30kt, with HREF MU
CAPE output 500-1000 j/kg. Gusty wind will be possible with
storms generally along and west of a line from FKL-PIT-MGW,
though the amount of destabilization could be a limiting factor
in storm strength and organization. East of this line,
instability is expected to diminish before the arrival of the
front, so left out any mention of thunder for the eastern
airports.

MVFR, and eventually IFR, is expected in after FROPA in post
frontal showers and cold advection. A gradual return to VFR is
expected by Saturday afternoon, though a crossing upper trough
and cold advection will maintain a low VFR stratocu layer.

.Outlook...
Late night/early morning river valley steam fog is possible
early Monday and Tuesday mornings with cool air temps over warm
river water. Otherwise, VFR is expected through Wednesday under
high pressure.

PA...None.
OH...None.
WV...None.
