Pittsburgh Bakes Saturday As Storm Threat Crashes In Sunday

Early risers in Pittsburgh woke up to a quiet, sticky start at 5:35 a.m. EDT today, with clear skies and a reading of about 63°F at the Allegheny County reporting station. Dew points are hanging in the low 60s, giving the air that familiar muggy feel. High pressure is in charge today, which means plenty of sun and a warm high near 87°F, along with a light west breeze through the afternoon. Patchy river‑valley fog may linger in the lowest spots early on but should fade out by midmorning.

Afternoon Heat

By this afternoon, the thermostat is expected to jump into the upper 80s under mostly sunny skies, with west winds around 1 to 7 mph. It will likely be the hottest day of this brief quiet stretch, so outdoor workers, pet owners, and anyone planning to linger outside will want to think hydration and shade. If you can, shift the heavy lifting, runs, and yard work to the cooler early morning or evening hours.

Severe Storm Risk Sunday

tomorrow, tells a very different story. An approaching cold front is set to drag in showers and thunderstorms, with rain and rumbles potentially showing up by late morning. The main window for stronger, possibly severe storms runs from about 2 p.m. to 6 p.m. Forecasters are watching for damaging wind gusts and brief tornadoes, along with downpours capable of dropping a quick quarter to half inch of rain, with a few spots seeing more. The severe threat should wind down from west to east later Sunday evening, roughly between 9 p.m. and 11 p.m. This setup is outlined by the National Weather Service.

Commute And Events

If you have outdoor plans, games, or a Sunday evening drive on the agenda, keep an eye on the sky. Gusty winds, lightning, and bursts of heavy rain can move in quickly, so have a solid indoor backup plan or nearby sturdy shelter. Roads can turn slick in a hurry during those heavier downpours, so budget extra travel time and avoid driving through standing water, no matter how shallow it looks.

Some practical prep goes a long way: keep your phone charged so you can receive weather alerts, secure loose outdoor furniture before storms arrive, and when you see lightning or hear thunder, head inside and stay there until the storm passes. Monday through midweek looks calmer again, though forecasters are already flagging another unsettled stretch around Thursday, June 18, so check local updates before locking in late‑week plans.
