Pittsburgh woke up damp and gray on Saturday, May 9, 2026, with light rain and temperatures hovering near 52°F. Steady showers are likely through midmorning before clouds start to break and the air turns noticeably milder. By afternoon, readings should climb into the upper 60s to around 70°F with a southwest breeze in play. Later in the day, however, a narrow late afternoon and evening window could bring stronger storms. You will want the umbrella for the morning runaround and a little flexibility in your evening schedule in case gusty showers and storms line up.
Morning Commute
Showers are expected to be most widespread through about midday, which means wet pavement and occasional reduced visibility on bridges and in the valleys. Build in a few extra minutes for errands, kids' activities, or appointments. Most neighborhoods are only projected to pick up a few tenths of an inch of rain, but a couple of heavier bursts cannot be ruled out. If you planned outdoor time early in the day, your best bet is to move it inside or push it closer to the midday warm-up if your schedule allows.
Evening Storm Risk
Later today, thunderstorms may fire up near Lake Erie and then race southeast toward the region, setting up a brief 2 to 3 hour window late this afternoon into the evening for gusty winds and isolated hail in the stronger cells. Forecasters with the National Weather Service in Pittsburgh say the marginal severe threat is mainly focused north of the I-80 corridor, but a decaying line of storms could still bring strong gusts and lightning into parts of the metro between roughly 5 and 10 p.m. If you are heading out tonight, give outdoor plans an on-call backup option and skip standing under that lone tree when lightning starts popping.
Looking Ahead
Showers remain possible again on Sunday with highs near the upper 60s, then a cooler pattern slips in as early next week gets underway. A push of colder air behind a passing system could leave low spots and sheltered backyards flirting with frost Monday night, so gardeners should be ready to cover tender plants.

By Tuesday, high pressure looks set to build back in, which should deliver a more settled and sunnier day.
How To Plan
Think layers. Pack rain gear and an umbrella for the morning, then a light jacket for cooler pockets overnight. Southwest winds will pick up into the afternoon, around 8 to 12 mph, with stronger gusts possible in any showers or storms. If you have evening travel or events, keep an eye on local transit and venue updates, and leave weather notifications on in case any short-notice storm warnings are issued.
