Area Forecast Discussion
National Weather Service Pittsburgh PA
831 AM EDT TUE JUL 26 2016

.SYNOPSIS...
Warm and dry weather can be expected until the approach of low
pressure on Thursday.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Minor adjustments were made based on latest surface and satellite
observations this morning. The surface boundary will slowly drag
southward, bringing relatively cooler dew point temperatures across
the area today. The boundary is expected to stall near the PA/WV
border while a weak shortwaves shifts across the southern CWA to
help induce weak convection. Thus, slight to chance pops remain
across the southern most zones. Temperatures will be above normal,
but much less humid conditions are expected than previous several
days.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH THURSDAY/...
Zonal flow/flat ridging should maintain dry, but continued warm
weather through Wednesday. Thereafter, POPs will be on the
increase with the approach of low pressure, timing of which
remains questionable on Thursday.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
A series of shortwaves and development of a broad, but shallow
trough over the Eastern CONUS is forecast to support periodic rain
chances and seasonal temperatures through the weekend.

&&

.AVIATION /13Z TUESDAY THROUGH SATURDAY/...
After early morning MVFR/local IFR fog mixes out, VFR conditions
are expected through this evening as high pressure builds in from
north of I 70. A stationary front south of I 70 could result in a
few thunderstorms, but with limited coverage expected only
mentioned VCTS at MGW. Patchy MVFR fog is again possible tonight.

.OUTLOOK /WEDNESDAY THROUGH SATURDAY/...
Low pressure should return periodic restrictions late Thursday
though Saturday.

&&

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