The forecast for Pittsburgh is shedding its rainy coat, at least temporarily, as the stalled frontal boundary that's been drenching the region begins to drift south today. In an update from the National Weather Service, the barometer of storms is set to take a brief respite. A decrease in PoPs during the daylight hours, with most locations from PIT on north expected to remain dry, the forecast read.
Nevertheless, the skies aren't clear for long. As the Weather Service's forecast explains, another shortwave lifting north through the area tonight will bring the front back and usher in more rain. During the day on Sunday, the surface low will push east, bringing additional heavy rainfall, according to the bulletin details, ushering in a period that could spell trouble for those with an eye on the skies or vulnerable spots on the ground.
The outlook for Sunday through Tuesday is riddled with the potential for heavy showers and, possibly, thunderstorms. Marginal severe weather and excessive rainfall outlooks are on the agenda for Sunday, according to the forecast. Monday isn't free from concern either, with roughly an 80% probability for over 1000 J/Kg of SB CAPE, hinting at a stronger potential for storm development.
By Tuesday, as a trough makes its way across the Central Great Lakes and over the Upper Ohio Valley, Pittsburgh can expect another round of showers and storms before a long-awaited shift in the weather pattern. Come Wednesday, a high-pressure system is anticipated to bring drier, less humid conditions through at least Thursday night. Aviation forecasts similarly predict weather-induced challenges, with widespread early morning fog giving way to flight-friendly visibility later in the day, before the Sunday warm front likely returns restrictions to the skies.
No advisories, watches, or warnings are currently in place for Pittsburgh or its surrounding regions in Ohio and West Virginia. However, Pittsburgh residents and visitors are advised to stay informed about the changing conditions as the water-laden week progresses. It's that time of year in Pittsburgh when umbrellas should never be stored too far out of reach.
