Thursday, July 16, 2026, is bringing a one-two punch to Pittsburgh: a warm, sunny start in the mid 70s followed by thickening wildfire smoke and low 90s heat that could derail afternoon outdoor plans.
Smoke And Air Quality
State officials have declared a Code RED Air Quality Action Day for Thursday, warning that drifting wildfire smoke could make conditions unhealthful for the general population and urging residents to avoid outdoor exercise and strenuous activity, according to the Pennsylvania Department of Environmental Protection. The alert covers the greater Pittsburgh region, with children, older adults, and people with respiratory or heart conditions highlighted as the most vulnerable.
Today And Tonight
Forecasters expect smoke to become more noticeable after noon, with a daytime high near 93°F and generally light west winds around 0–10 mph. The hottest stretch will hit in the mid afternoon. Tonight should stay mostly clear with a low near 67°F, although smoky conditions may hang on into Friday until either a change in the wind or incoming showers helps clear the air.
Weekend Outlook
Storm chances return late Friday into Saturday, and showers and thunderstorms could be heavy at times with a spotty risk of strong storms and localized heavy rainfall. Outdoor plans this weekend should come with a solid indoor backup. The wetter pattern should help flush out lingering smoke but will also bring pockets of heavy downpours and brief flooding where storms repeatedly track over the same neighborhoods, so it is worth watching the timing for any large outdoor gatherings, according to the National Weather Service.
What To Do
Anyone with asthma, heart disease, or other respiratory issues is advised to stay indoors with windows closed and use air conditioning on recirculate if possible. State guidance for the Code RED period specifically recommends avoiding strenuous outdoor activity. If you have to be outside, wear an N95-style mask, take it easy, and check updates through state and federal pages before heading out, per the Pennsylvania Department of Environmental Protection.
