As Pittsburgh braces for another round of summer sizzle, the National Weather Service Pittsburgh PA has issued its latest weather forecast, warning residents to prepare for a potential mix of high heat and stormy weather over the weekend. The forecast discussion, published early this morning, outlines a warm Saturday ahead with "isolated shower storm coverage," leading into a Sunday that could bring severe weather and flash flooding risks.
The city is poised to experience high temperatures in the 90s today, with heat indices flirting with the 100-degree mark, especially in densely populated urban centers and river valleys, which could see temperatures spike even higher, according to the National Weather Service. Residents should be aware that isolated thunderstorms are also possible this evening into tonight, particularly across east-central Ohio. These storms, if they develop, could bring damaging wind gusts and localized heavy downpours, potentially leading to flooding issues in susceptible areas.
Looking ahead to Sunday, the threat level ratchets up a notch with slightly higher severe wind threats and flash flooding threats, as reported by the National Weather Service. A cold front approaching the area might increase the likelihood of storms. However, there's a catch to this increased activity—this does not guarantee that all storms will be severe, boding a marginal but notable risk nonetheless.
By the time Monday rolls around, temperatures are expected to linger in the mid to upper 80s, with some showers and storms still in the mix. However, the potential for severe weather and flooding appears to be on the wane at this point, giving a bit of a respite before another uptick mid-week, when temperatures and humidity are likely to escalate once more as we lean into Wednesday with heat/humidity possible on Wednesday, according to the National Weather Service.
For aviators, the forecast predicts consistency with a persistence forecast, implying that conditions are not expected to change significantly through Wednesday. However, there may be isolated showers or storms later this weekend. The Weather Service advises that while the probabilities of showers or storms affecting flight are less than 20-30%, the approach of a surface cold front and other weather phenomena on Sunday favor certain areas, like western PA and high terrain, for more widespread convection.
No watches, warnings, or advisories have been issued at this time, allowing Pittsburgh residents to carry on with weekend plans while remaining weather-wise.
