Area Forecast Discussion
National Weather Service Pittsburgh PA
1035 AM EDT Fri Aug 26 2016
Hot and dry weather can be expected until late Sunday.
.NEAR TERM /THROUGH TONIGHT/...
8am update to remove patchy fog. reset unchanged...
High Temperatures about 7 degrees above the averages are again
forecast as last nights crossing shortwave did not appreciably
changes the airmass.
.SHORT TERM /SATURDAY THROUGH MONDAY/...
The upper ridge of high pressure over the southeastern U.S. will continue
to funnel warm air across the northern periphery, i.e. the Upper
Ohio region. Temperatures about 7 to 10 degrees above the
averages may thus be expected into early next week. Surface high
pressure will ensure dry weather for most of the weekend, with
somewhat lower dewpoints until southerly flow resumes on Sunday.
A Great Lakes shortwave traversing the northern flank of the
aforementioned upper ridge is forecast to trigger the next rain
chance on Sunday with focus via outflow or lake breeze. Confidence
in that scenario is minimal at moment, so little change was
completed for that portion of the forecast.
.LONG TERM /MONDAY NIGHT THROUGH THURSDAY/...
Shortwave energy and tropical encroachment on the Southeastern
Coast is progged to flatten flow across the northern tier of the
CONUS next week. The disturbances in flow would support periodic,
and diurnally-enhanced precip chances, but confidence in timing
and the magnitude of the pattern change are low, so the forecast
was constructed with chance PoPs and an ease away from the warmth
by the latter half of the week.
.AVIATION /15Z FRIDAY THROUGH TUESDAY/...
VFR conditions are expected through the forecast period. Fog will
burn off quickly after sunrise.
.OUTLOOK /FRIDAY NIGHT THROUGH TUESDAY/...
The next chance for restrictions should come with the approach of
a front Sunday and Monday.
