Sunday, July 26, started quietly in Pittsburgh, with clear skies overhead and pockets of river-valley fog hugging the low spots. Early temperatures sat in the mid-60s, and the thickest fog is expected between about 8 a.m. and 9 a.m. The low clouds should burn off quickly after sunrise, leaving mostly sunny skies this afternoon with a high near 86°F and light northwest winds around 0–6 mph. It will feel increasingly humid by late day, so if you are planning to linger outside, think shade, water, and maybe a quick escape indoors.
Morning Fog, Sunny Afternoon
Drivers in low-lying neighborhoods and along the rivers should be ready for reduced visibility during the early commute. Give yourself a few extra minutes on bridges and riverfront roads while the fog hangs around. As the sun gets higher through late morning, skies will clear and humidity will climb along with the temperature into the mid-80s. With winds staying on the light side, do not expect much natural breeze-based relief until the sun starts to dip.
Storm Threat Monday–Tuesday
The quiet stretch looks short-lived. By Monday, July 27, scattered showers and thunderstorms are possible as highs push into the upper 80s. The real action is expected Monday night into Tuesday, July 28, when showers and thunderstorms are likely. Heavier storms could drop roughly a quarter to a half inch of rain and carry a legit risk of damaging wind and large hail. Forecasters also note that isolated tornadoes cannot be ruled out, so it is worth keeping an eye on watches and warnings from the National Weather Service.
Plan Ahead
If you have outdoor plans Monday or Tuesday, line up an indoor backup and keep a weather app close for any last-minute alerts. For a look at how this threat has been building over the last few days, check our earlier breakdown of how the risk has evolved.
