Pittsburgh woke up to clear skies and about 57°F early Saturday morning, June 20, 2026, the kind of start that makes you think summer has finally settled in. Highs will climb into the upper 70s, near 78°F, with mostly sunny skies through midday. After that, the sunshine gets interrupted as a chance of showers and thunderstorms returns for the afternoon, mainly after about 2 p.m. West winds will pick up to around 6 to 14 mph, so it will feel a bit breezier than the calm morning.
What To Expect This Afternoon
Scattered showers and isolated thunderstorms are possible after 2 p.m., with the better odds north of the city. Most neighborhoods should stay dry for a good chunk of the afternoon, but any storm that does pop up could bring brief heavy downpours and gusty winds strong enough to flip unsecured patio umbrellas. If you have outdoor plans, keep a backup ready and check radar before you commit to that late-day cookout.
Sunday Night Into Monday
More organized and widespread rain moves in Sunday night and is likely to hang around into Monday, bringing a soaking round of showers and thunderstorms. Forecast guidance points to widespread totals commonly between a half and three quarters of an inch, with localized pockets possibly reaching three quarters to an inch or higher and a nonzero chance of isolated higher totals in some spots. Forecasters have high confidence in the heavier rain but currently low confidence in widespread flooding, so urban and poor‑drainage locations remain most at risk. Southeast winds could gust into the low 20s Sunday night, according to the National Weather Service Pittsburgh.
Afternoon Winds Pick Up
West winds will gust into the teens this afternoon and could briefly approach 20 mph during peak mixing, which means lightweight patio gear and umbrellas may not fare well if they are not secured. Winds should ease tonight, then shift southeast as the heavier rain approaches Sunday night.
Plan Ahead
If you have outdoor plans for Sunday night or Monday, move them indoors or have a solid backup ready, since the heaviest rain will target the evening and overnight hours. Expect slick roads and localized ponding that could slow the Monday morning commute, so give yourself extra time and avoid driving through standing water.
