Pittsburgh woke up in a cool, clammy hug of river‑valley fog on Thursday, July 23, 2026, with temperatures sitting in the mid‑50s. The gray start will not last long, though, as the fog is expected to burn off quickly after sunrise, making room for bright sunshine and a comfortable high near 78°F with light north winds.
Morning Fog, Sunny Afternoon
Drivers in low‑lying neighborhoods and along the rivers can expect reduced visibility through about 8 a.m. Thursday, July 23, 2026, so it is worth building in a little extra travel time early. Once the fog lifts, skies turn mostly sunny and pleasant, with light north winds around 0–6 mph helping to keep humidity from getting out of hand.
Weekend Warm‑Up With Spotty Showers
Temperatures will climb into the low to mid‑80s on Friday, July 24, and Saturday, July 25. Most of the time looks dry, but there is a small chance of an afternoon pop‑up shower on Saturday, about a 20 percent shot. Forecasters at the NWS Pittsburgh still expect generally dry and cool conditions through Saturday before the pattern shifts, so outdoor plans this weekend are mostly good to go, with a lightweight rain jacket as a just‑in‑case accessory.
Severe Risk Returns Early Next Week
From late Sunday, July 26, into Tuesday, July 28, forecast models point to a stronger chance for organized thunderstorms that could bring heavy rain and damaging wind gusts. Localized flooding is possible if an organized system sets up over the area. For background on the evolving threat and the recent flood watch, see our earlier look at the severe storms and flood watch, and keep an eye on updated watches and warnings through the weekend.
What To Watch And How To Prepare
If you have outdoor events scheduled from Sunday night through Tuesday, it is smart to have a backup indoor plan ready and to monitor forecast updates. Be prepared to move activities inside if severe thunderstorm watches or warnings are issued. If heavy rain does arrive, avoid driving through flooded roads, and seek sturdy shelter if lightning or strong winds move in.
