Area Forecast Discussion
National Weather Service Pittsburgh PA
924 PM EDT Sun May 27 2018

.SYNOPSIS...
Warm and humid conditions will persist with showers and thunderstorms
becoming more widespread during the latter half of the week.

&&

.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...
No changes were needed for the late eve update

Previous...
Changes for the early eve were primarily cosmetic as slight
rain chances will continue for areas east of I 79 due to the
presence of the persistent shortwave trough and abundant
moisture over the region.

The residual rain chances will fade with the setting sun, but
boundary layer humidity and a clearing sky is expected to
support fog development. The high dewpoints will again limit the
temperature drop, so morning lows will again be well above the
averages.

&&

.SHORT TERM /6 AM MONDAY MORNING THROUGH TUESDAY/...
Broad ridging will keep a lid on convection and result in
continued warmth and humidity through Tuesday.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/...
Warm and humid conditions are expected through the extended
with daily chances for showers and storms as low pressure currently
over the gulf is progged to impact the region later in the week.

&&

.AVIATION /01Z MONDAY THROUGH FRIDAY/...
VFR conditions expected this evening as lingering clouds and
showers diminish. The stagnant, moist air mass and clearing sky
will combine to develop fog for the peri-dawn hours. This should
impact most ports, but the typical fog-favored locations will
be the most impacted.

OUTLOOK...
General VFR can be expected into midweek outside of isolated to
scattered convection.

&&

.PBZ WATCHES/WARNINGS/ADVISORIES...

OH...None.
