Pennsylvania – Cool morning air across Pittsburgh will give way to a striking late-summer warm-up, culminating in 93-degree heat Wednesday. The five-day trend favors dry weather before rain chances finally return Wednesday evening.
According to the National Weather Service in Pittsburgh, Allegheny County Airport reported 61 degrees shortly before 9 a.m. Humidity stood at 70%, with southeast winds near 5 mph.
Sunshine pushes Pittsburgh to 81 degrees today. Winds remain light, keeping travel conditions favorable along I-376, I-279 and the Pennsylvania Turnpike.
Temperatures fall toward 64 this evening under partly cloudy skies. No precipitation appears in the local outlook.
Sunday turns noticeably warmer. Mostly sunny skies send temperatures to 88 degrees, seven degrees above today’s high.
Sunday evening remains dry near 69 degrees as clouds increase.
Monday offers little relief from the warming trend. Pittsburgh reaches 88 again under partly sunny skies. Temperatures remain unusually mild into the evening, dropping only to 72.
Then summer heat takes control.
Tuesday reaches 92 degrees with partly sunny skies. Wednesday climbs another degree to 93, producing the hottest conditions in the supplied five-day outlook.
That represents a 12-degree increase from today’s expected high. Residents working outside should shift strenuous activity toward morning and drink water regularly.
Drivers should also check vehicles before longer trips. Hot pavement and prolonged sun can increase stress on tires and cooling systems.
The Weather Prediction Center expects a stationary front to extend toward the Mid-Atlantic by Monday. However, Pittsburgh’s local NWS data keeps conditions dry through Wednesday afternoon.
A meaningful change arrives after 8 p.m. Wednesday, when the shower chance jumps to 50%. Showers and thunderstorms remain possible Thursday.
No tornado threat, snow, ice or near-freezing temperatures appear in the supplied data. Additional weather alerts could follow as Wednesday’s rain window approaches.
