1145 AM EDT Sat Aug 2 2025
.SYNOPSIS...
Relatively cooler and drier conditions can be expected over the
weekend. Rain chances return by the middle of next week, but
severe weather is not expected over the next seven days.
&&
.NEAR TERM /THROUGH TONIGHT/...
KEY MESSAGES:
- Cool and dry conditions today
---------------------------------------------------------------
Building high pressure will maintain dry, benign weather
conditions today. While upper- level winds are from the
northwest, they will be weak, limiting the entry of Canadian
wildfire smoke into eastern Ohio and western Pennsylvania.
Temperatures will top out several degrees below average.
&&
.SHORT TERM /SUNDAY/...
KEY MESSAGES:
- Quiet and dry conditions continue into Sunday
- Rocky Mountain wildfire smoke may linger
----------------------------------------------------------------
Confidence remains high that dry and quiet weather will likely
continue into Sunday under high pressure. Hazy conditions from
Rocky Mountain wildfires, which have affected the Great Plains,
may reach the region late Sunday morning with the progression of
a weak trough. Otherwise, Sunday's temperature are expected to
be near average.
&&
.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
KEY MESSAGES:
- Dry conditions through Monday.
- Slight chance of showers and storms late week
-------------------------------------------------------------------
There is high confidence in dry conditions persisting through at
least Monday as high pressure dominates the local forecast. A
slight warming trend will begin, however, with temperatures
climbing back above normal to the mid/upper 80s Sunday and
Monday afternoons.
Ensembles continue to suggest a trough moving from the Midwest
into the Ohio Valley Tuesday into Wednesday. While lingering dry
air may initially serve to hinder the development of showers and
storms, some low-end precipitation potential returns Tuesday
into Wednesday south and west of Pittsburgh.
Beyond Thursday, models are not consistently indicating
significant heavy rain or thunderstorm activity. It is probable
that two areas of heavy rainfall will develop: one over the
Carolinas and another in the Midwest, associated with passing
troughs.
&&
.AVIATION /16Z SATURDAY THROUGH WEDNESDAY/...
High pressure will maintain dry conditions today with relatively
light winds due to a weak pressure gradient.
VFR is expected through the TAF period although high level
clouds will stream overhead through the daytime hours.
Outlook...
High confidence in a prolonged period of VFR (save for
morning river valley steam fog) with dry weather through the weekend
and into early portions of next week.
&&
.PBZ WATCHES/WARNINGS/ADVISORIES...
