Enjoyable weekend events such as concerts and fairs will benefit from continued good weather.
Pittsburgh is gearing up for an extended period of hot and humid weather, according to local meteorologist Ron Smiley of KDKA. The upcoming days will feature high temperatures around 90-93°F, making it feel even hotter due to the increasing humidity.
Currently, the city is in the midst of an extended dry spell, with no rain recorded for 14 consecutive days as of August 12, 2025. The forecast indicates that this trend will continue throughout the week, with mostly dry conditions prevailing. However, there is a slight chance of isolated storms or showers toward the end of the week or weekend.
Despite the lack of significant rainfall, a weak front is expected to move and stall over Pittsburgh, causing a consistent rain chance late Tuesday and persisting through Wednesday and Thursday. This rainfall should help lower the temperatures, which are still expected to be in the 90s for Monday and Tuesday of the next week.
The weekend looks warm and partly sunny, with a risk of afternoon thunderstorms or showers. High temperatures on Saturday will be in the mid to upper 80s, and temperatures for the middle of next week will remain in the same range.
Humidity levels will remain low through Sunday morning, but they are expected to rise to a moderate range starting Sunday. It's possible for temperatures to briefly hit 90 degrees on Sunday due to dry air. Another temperature surge is expected next Saturday, bringing high temperatures back to the 90s.
Precipitable water levels are expected to be in the moderate range, and any potential flash flooding will be isolated. Dew points on Sunday are expected to be in the upper 50s.
Residents are advised to stay hydrated and take precautions against the heat, especially during the afternoons when temperatures will be at their highest. Keep an eye on weather updates for any changes in the forecast, particularly as we approach the weekend.
On Tuesday and Wednesday, a weak front may bring consistent rainfall to Pittsburgh, potentially helping lower the persisting high temperatures in the 90s. However, the upcoming weekend is predicted to be warm and partly sunny, with a risk of afternoon thunderstorms or showers, and humidity levels are expected to rise, potentially causing temperatures to briefly hit 90 degrees on Sunday.
