Pittsburgh residents can look forward to the clouds parting ways and the sun peeking through as the weekend progresses. According to the National Weather Service, conditions are set to improve throughout the day while "intermittent drizzle may linger during the morning hours," especially in the northern regions and the ridges. The day's highs are expected to be slightly warmer than Friday's, offering a gentle reprieve from the cool blanket over the city.
As the evening draws in, Pittsburgh's residents might observe a decrease in cloud coverage due to the movement of the ridge axis overhead. Such conditions increase the likelihood of fog forming early on Sunday, especially along the ridges where "patchy dense fog" is expected. However, this prediction holds the highest chance of being south of the city at locations like ZZV, HLG, and MGW. As the flow shifts, Sunday afternoon temperatures are anticipated to climb into the "upper 50s to lower 60s," the National Weather Service detailed.
Looking into next week, uncertainty hovers over the weather forecast for mid- to late-week, with the National Weather Service citing high uncertainty remains with a late-week system. However, the onset of the week seems to be clear-cut, with predictions of rainfall on Tuesday as a surface low-pressure system moves through the Great Lakes. This will precede a cold front and potentially usher in temperatures 10-15 degrees above the average for this time of year.
By the latter part of the week, the weather narrative might take a dramatic shift with the development of a more potent wave or closed low over the Central U.S. This could potentially bring about a mixture of precipitation and, as the National Weather Service points out, introduce the possibility of rain/snow mix into the fray for Thursday and Friday, temperature-dependent, of course.
Given the variable conditions, travelers and commuters should stay tuned to the latest updates as the ensemble forecast elements across these days show this bimodal variance. In the meantime, aviation operations can expect mostly MVFR stratocumulus clouds today before conditions clear up to VFR by Sunday, thanks to more significant mixing and drier southwest flow. However, as we head into the week, an active mid to late-week weather pattern will likely bring multiple waves of precipitation and potential travel disruptions.
