Area Forecast Discussion
National Weather Service Pittsburgh PA
1207 PM EDT TUE MAY 31 2016

.SYNOPSIS...
Dry and warm weather can then be expected through Wednesday. A
cold front will increase rain chances for the latter half of the
work-week.

&&

.NEAR TERM /THROUGH TONIGHT/...
The only changes needed for the early afternoon update involved
adjustments to hourly trends as cirrus/cumulus-filtered
insolation and slightly lower dewpoints support a rise into the
mid 80s for most locations off the ridges. Expect morning lows
about 5 degrees above the averages as radiation promotes a
comfortable night.

&&

.SHORT TERM /WEDNESDAY THROUGH THURSDAY/...
Dry and warm weather can be expected Wednesday under eroding high
pressure. Models remain in overall agreement in depictions of a
shortwave/associated cold frontal approach Wednesday night and
Thursday, with gradual pop escalation to "likely" numbers by
Thursday. Above average temperatures are anticipated given the
warm, moist advection in advance of the system.

&&

.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
Little change to previous thinking as model guidance suggests
that the front will lag in complete passage through Friday with
chance pops maintained. While differences in evolution of the
pattern over the weekend into early next week remain, overall
trend of developing and deepening mid and upper level trough
continues in all models, as a series of shortwaves move through
the base of the trough. Will keep shower chances through the
period. Temperatures will trend 5 to 10 degrees below average by
early next week.

&&

.AVIATION /16Z TUESDAY THROUGH SATURDAY/...
High pressure will maintain general VFR for the TAF period with
exceptions for peri-dawn fog.

.OUTLOOK /WEDNESDAY THROUGH SATURDAY/...
Restrictions are likely with a late week cold front.

&&

.PBZ WATCHES/WARNINGS/ADVISORIES...
MD...None.
OH...None.
PA...None.
WV...None.
