Area Forecast Discussion
National Weather Service Pittsburgh PA
1114 AM EDT Fri Aug 26 2016
Hot and dry weather can be expected until late Sunday.
.NEAR TERM /THROUGH TONIGHT/...
Forecast generally remains on track as large ridge continues to
build over the region. Dewpoints in the mid 60ss to 70 remain so
it will still feel humid today. A small are of thunderstorms tied
to a weak shortwave continue to approach western Ohio but is
quickly losing support. The hrrr had these storms weakening before
they reach our eastern Ohio zones but a brief shower may be
possible over Muskingum or Coshocton counties. Did not think this
was significant to make drastic alterations to the forecast
however. Otherwise expect a warm day with values in the upper 80`s
and lower 90`s across the region.
Clear skies and light wind overnight should allow for temperatures
to get close to average for lows.
.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
average may 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.
.OUTLOOK /FRIDAY NIGHT THROUGH TUESDAY/...
The next chance for restrictions should come with the approach of
a front Sunday and Monday.
