This morning Pittsburgh starts off clear, soupy, and sitting in the low 70s, but the atmosphere will not stay quiet for long. Temperatures are expected to climb toward a sticky high near 88°F, and scattered showers and thunderstorms are likely later today, with the best chance for storms south of I-70. Patchy river-valley fog could slow the early commute, and any afternoon storm could pack brief heavy downpours and gusty winds. If you have outdoor afternoon plans, keep them flexible: storms are expected to develop during peak heating and may pop up quickly.
Afternoon Storms And Timing
Isolated rain showers are possible in the late morning, around 8 to 9 a.m., with isolated thunderstorms developing around midday and scattered storms becoming more likely from about 1 to 4 p.m. The high is still forecast to land near 88°F. The NWS Pittsburgh pegs today’s precipitation chance at roughly 50% and notes that storms could produce localized heavy rainfall and gusty winds, especially for communities south of I-70. Expect southwest winds around 1 to 8 mph through the afternoon and new rainfall amounts generally under a tenth of an inch, with a few spots picking up higher totals under stronger cells.
Commute And Event Tips
Fog is the main early-morning troublemaker, particularly along rivers and bridges, so build in some extra time for the drive and use low beams if visibility drops. For outdoor gatherings, have a quick shelter plan ready; storms should move along but can occasionally stall and dump heavy rain over one area. We ran a similar update yesterday; see our earlier coverage for context in yesterday’s foggy, steamy setup.
Weekend Outlook
The unsettled pattern hangs on into Friday and Saturday, with Friday looking like the wetter day and the potential for locally heavy totals where storms train over the same areas. By Sunday the upper flow is expected to turn northwest and shove the surface boundary south, which should bring back mainly dry and warmer weather into next week, with highs climbing into the mid-80s and nearing 90°F by Tuesday.

Quick Take
Bring a light rain jacket or umbrella this afternoon and keep an eye on radar if you plan to be outside; in this kind of heat, conditions can flip fast. Check NWS updates before traveling or hosting large outdoor events, and move vulnerable activities indoors if thunderstorms are in the forecast.
