Early Thursday morning in Pittsburgh is clear and around 75 degrees, but the easy part of the forecast will not last. September 3 is expected to climb to near 92 degrees with a heat index up to 102, while showers and thunderstorms are possible in the morning and again later in the day.
Heat Advisory Runs Through Thursday Evening
The Heat Advisory remains in effect across Pittsburgh until 8 p.m. Thursday. Humidity will make the afternoon feel hotter than the thermometer suggests, with west winds around 5 to 9 mph. The National Weather Service recommends drinking plenty of fluids, staying in air conditioning or shade, and checking on neighbors who may be more vulnerable to heat illness.
Storms Complicate Thursday Plans
Storm chances start with a slight possibility early Thursday, then increase through the morning and afternoon, with a 50% chance of precipitation overall. Thunderstorms can produce heavier downpours and make outdoor plans or evening travel less predictable.
Friday Turns Wetter Before Weekend Reset
Friday looks like the wettest day of the stretch, with showers and thunderstorms likely, an 80% chance of rain, and a high near 86 degrees. Rain should ease later Friday as the unsettled pattern winds down. The latest forecast extends the unsettled pattern beyond the Thursday focus of Hoodline's earlier Pittsburgh forecast.
Weekend Plans Get A Break
Saturday brings a chance of rain showers before 2 p.m., followed by partly sunny skies and a high near 81 degrees. Saturday night drops to around 60, setting up a sunny Sunday near 80 and a sunny Labor Day near 82. Tuesday should remain mostly sunny near 83, while a chance of showers returns Wednesday with a high around 86.
Stay Cool And Take Storms Seriously
Limit strenuous activity during the hottest part of Thursday, drink water regularly, and take breaks from direct sun. Older adults, young children, and people with underlying health conditions can be especially vulnerable to heat illness. If thunder is heard, move indoors and wait for the storm to pass; cooler, quieter weather arrives Saturday.
