Area Forecast Discussion
National Weather Service Pittsburgh PA
1201 PM EDT Fri Oct 20 2017

.SYNOPSIS...
High pressure will maintain dry and warm weather through the
weekend.

&&

.NEAR TERM /THROUGH TONIGHT/...
-- Changed Discussion --With noon update, increased high temperatures 2-3 degrees in
all locations considering trends through the morning hours.

High pressure will remain over the area today, keeping a dry
and mostly clear forecast. The upper-level ridge will build
through this evening, allowing our daytime highs to creep up
from yesterday`s readings. Have bumped temperatures up a few
degrees in some spots, but generally highs will be about 10
degrees above the average. Lows should stay fairly consistent
from last night, about 5 degrees above average.-- End Changed Discussion --

&&

.SHORT TERM /SATURDAY THROUGH SUNDAY/...
High pressure will remain anchored through the weekend, keeping
it warm and dry. Despite an increase in cirrus and the ridge
axis shifting east late Saturday, increasing southwesterly flow
will allow temperatures to climb further and by Sunday readings
will be about 15 degrees above average.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
High pressure ridge shifts east Sunday night into Monday as the
broad western CONUS trough trudges eastward. Models differ
slightly in the evolution and timing of the trough, but despite
these timing differences, a pattern change will occur early
next week, bringing rain and eventually much cooler
temperatures.

&&

.AVIATION /16Z FRIDAY THROUGH TUESDAY/...
-- Changed Discussion --VFR conditions are once again expected through the period
underneath high pressure. Winds will remain light out of the
southwest.

.Outlook...
Restrictions are likely with a Monday cold front.-- End Changed Discussion --
