Area Forecast Discussion
National Weather Service Pittsburgh PA
1031 AM EDT SAT MAY 28 2016
Warm temperatures with periodic shower and thunderstorm chances
are expected through the weekend. High pressure should result in
dry weather for Memorial Day.
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
-- Changed Discussion --Forecast right on track. No updates needed at this time.
Previous discussion follows.
Minor adjustments made to hourly grids based on current conditions
for the near dawn update. Previous discussion-Ridging is expected
to remain centered off the mid Atlantic coast today. A few showers
and thunderstorms are possible this afternoon as instability
increases and convective temperatures are reached, though a lack
of shortwave support and proximity to the ridge should help limit
coverage to isolated for most areas. Temperatures should continue
to average 10 to 15 degrees above seasonal levels.

.SHORT TERM /6 PM THIS EVENING THROUGH TUESDAY/...
Any isolated showers/storms should quickly dissipate this evening
as the atmosphere stabilizes.
A trough advancing out of the midwest should approach the region
Sunday as the ridge shifts east. Increasing moisture in southerly
flow should bring better coverage of showers and thunderstorms
by Sunday afternoon and evening. These should taper off overnight
after the passage of the trough. Building surface high pressure
should bring mainly dry weather for Memorial Day and Tuesday.
Temperatures are expected to average around 10 degrees above
.LONG TERM /TUESDAY NIGHT THROUGH FRIDAY/...
High pressure across the eastern United States should allow for
dry weather Wednesday. An upper level trough and an associated
cold front will approach and cross the region Thursday and Friday
with increasing showers and thunderstorms. Above normal
temperatures mid week will begin to trend toward the seasonal
average late week.
.AVIATION /15Z SATURDAY THROUGH WEDNESDAY/...
VFR at all ports through the taf period. A ridge of high pressure
will keep thunderstorms isolated at best with no mention in tafs.
Winds will be light from the south.
.OUTLOOK /SATURDAY NIGHT THROUGH WEDNESDAY/...
The next chance for more widespread restrictions will be ahead of
a weak front sunday into monday.
