Friday, July 3, 2026: Pittsburgh is kicking off Independence Day weekend hot, humid, and already uncomfortable. Mostly clear skies this morning have temperatures hovering around 79°F at area stations, with a forecast high near 97°F later today. Heat index values are expected to push into the low 100s this afternoon, and officials are warning residents to plan for limited overnight relief and to take extra care if they have to be outside during peak heat.
Extreme Heat Warning Through Saturday
An Extreme Heat Warning covering Allegheny County and many surrounding communities remains in effect through 8 p.m. Saturday, July 4. According to the National Weather Service, heat index values could reach into the low 110s in some locations, with nighttime temperatures offering only modest cooldowns. The warning notes that the risk of heat-related illnesses rises sharply in conditions like these and urges people to stay hydrated and avoid direct sun during the hottest hours of the day.
Cooling Centers And Where To Go
CitiParks is keeping four cooling centers open through Sunday, July 5 to give residents a place to escape the worst of the heat. Three of the sites will operate Friday through Sunday from 12:00 p.m. to 6:00 p.m., while the Sheraden location will be open Friday and Sunday but closed on Saturday. Visit the City of Pittsburgh for exact locations and hours, or call 311 or 2-1-1 if you need help finding a site.
Storms Could Complicate Fourth Of July Plans
The atmosphere is not done playing games with weekend plans. A chance of showers and thunderstorms is in the picture tonight between 7 p.m. Friday, July 3, and 3 a.m. Saturday, July 4. Storm chances increase again on Saturday afternoon, roughly between 1 p.m. and 5 p.m., with forecasters flagging the 4 to 5 p.m. window as the most likely time for showers and storms to pop. Any storms that do develop could bring strong, gusty winds and brief heavy downpours that may knock temperatures down temporarily but could also disrupt outdoor celebrations.
Plan Ahead
If you have outdoor plans, try to front-load activities into the morning or push them into the evening, keep plenty of water on hand, and make sure you have an indoor backup option. Never leave children or pets unattended in vehicles, check in on older neighbors or anyone who may not have access to air conditioning, and head for a cooler, air-conditioned space if you start feeling dizzy, faint, or unusually weak.
