Area Forecast Discussion
National Weather Service Pittsburgh PA
117 PM EDT Sun Jul 17 2022
.SYNOPSIS...
A series of low pressure systems will bring increased shower and
thunderstorm chances through Monday night. Hot and humid
conditions return by the middle of the week.
&&
.NEAR TERM /THROUGH MONDAY/...
The Ohio Valley remains in the warm sector of low pressure,
influenced first by vorticity advection today and by tomorrow,
frontogenesis. A periodically stormy period is anticipated,
beginning this afternoon.
Due to atmospheric setup which includes warm cloud layer up to
13kft, moisture convergence, high RH values through the column
and plenty of forcing, flooding will be a concern for areas west
of Pittsburgh, especially those that saw upward of 2 inches of
rain already this morning.
Once this system is influenced by the jet stream, organization
is possible and would lead to a damaging wind threat. Dew points
are already in the mid-upper 60s, so the only lacking factor for
organized convection is the wind field until the low propagates
closer to the area.
&&
.SHORT TERM /MONDAY NIGHT THROUGH TUESDAY NIGHT/...
Shower and thunderstorm activity will dissipate through Monday
evening as the upper trough axis and an associated sfc cold
front push through/exit the region. A shower or two may linger
over the higher terrain SE of Pittsburgh into Tuesday morning
with residual jet ascent on the backside of the trough.
Otherwise, dry conditions with increasing insolation are
expected Tuesday which, combined with weak warm advection, will
drive area temperature about 5 degrees above seasonal averages.
&&
.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
Long range model ensembles indicate hot and humid conditions
are expected as warm, moist advection ramps up ahead of the
next low pressure system expected mid-late week.
The general pattern of Rockies ridging and broad eastern CONUS
troughing will likely continue into next weekend. This setup
favors periodic precipitation chances attendant with shortwave
passage and above normal temperature.
&&
.AVIATION /17Z SUNDAY THROUGH THURSDAY/...
Widespread rain showers with pockets of thunderstorms will
impact the region as an upper level trough slowly crosses
through Monday. Expect generally VFR conditions through the
early evening while heavier storms cause MVFR/IFR vsyb
restrictions. Moist advection overnight will better foster
MVFR/IFR restrictions to cigs, favoring eastern OH to northwest
PA given proximity to sfc boundaries.
Uncertainty remains in the time windows of heaviest rainfall as
embedded shortwaves round the trough; also uncertain is overall
lightning activity, which may be hindered by cloud cover this
afternoon (which may limit activity to southern terminals) and
nocturnal cooling overnight.
.Outlook...
Overnight restrictions will be slow to improve Monday as
additional showers and isolated thunderstorms develop ahead of
a cold front. High pressure should return VFR conditions to most
terminals late Monday night, though dawn fog development will
need to be monitored.
