The Pittsburgh area is bracing for a deluge as the National Weather Service has issued a Flood Watch effective from 11 AM EDT, stretching through this evening for numerous counties across Pennsylvania, Ohio, and West Virginia. According to their latest forecast bulletin, Pittsburgh is in the direct path of heavy rainfall with rates that could reach up to 3 inches per hour in some areas, raising a moderate risk of flash flooding throughout much of the region today.
Precipitation won't be the area's only concern; isolated instances of damaging wind threats are also on the radar, particularly south of I-70 – this coupled with the flood potential makes for a nervy situation in southwestern Pennsylvania, especially in locales primed for flooding due to the recent saturation of the ground from prior rains. The National Weather Service highlighted an elevated risk of flooding, where showers with moderate to heavy rainfall rates could intensify the ongoing flood threat. This circumstance demands close monitoring, especially along a line from Zanesville, OH, to Pittsburgh.
As the weather pattern persists for Pittsburgh, showers and thunderstorms are expected to continue into Wednesday, along with the potential for strong to severe storms, the National Weather Service has warned. Stakeholders and residents should remain vigilant, as the region is under the influence of an unsettled southwest flow that is expected to last into midweek.
For aviation concerns, a mixed bag of flying conditions is forecasted to start Tuesday, with potential restrictions slated to hang in the air. Mixed visibility is expected to improve to VFR, except at FKL/DUJ, where MVFR may linger into the afternoon, and widespread IFR is set to settle in overnight as showers abate, yet low-level moisture remains. Across the board, light winds will persist, generally hailing from the south or southwest.
Looking ahead, the flood and severe weather threat will persist until Thursday when a cold front is due to pass. However, relief is in sight; the end of the week signals a welcome transition to drier and ultimately hotter conditions with temperatures predicted to soar into the 90s by the weekend. The aviation outlook sees more showers and thunderstorms on the horizon late Wednesday into Thursday. Still, general VFR conditions are expected to surface by Friday and linger through the weekend as ridging settles in over the region.
