Pittsburgh residents might want to keep their umbrellas handy. The National Weather Service Pittsburgh, PA, has forecasted an increase in precipitation chances this Saturday morning, with the possibility of snow by afternoon. Light scattered showers are expected throughout the day, with only a slight chance of measurable snow—less than 30 percent, according to the weather report. Temperatures and dew points have been slightly updated to reflect the current climate conditions, with rainfall totals ranging from a trace to 0.15 inches.
For those planning outdoor activities, it's worth noting that while rain may switch to snow during the afternoon in Pittsburgh and areas to the north and in higher elevations, surface temperatures, and a higher sun angle will likely prevent accumulation. Overnight, the forecast predicts a drop in temperature with the possibility of temperatures lowering by 15-20 degrees cooler than this morning, attributed to increased radiation cooling. This prediction is contingent on cloud coverage and the calming of winds by Sunday morning, as stated in the National Weather Service discussion.
Looking forward to the rest of the week, a low-pressure system will introduce another round of precipitation on Sunday into Monday. Totals of 0.25" to 0.50" are projected for the region by Monday afternoon. This system should move out by Tuesday morning. However, an upper-level low may linger, bringing scattered light showers and cooler temperatures through Thursday. Some relief is anticipated by Thursday when a surface high-pressure system is expected to move into the area, providing a period of dry conditions.
Aviation outlooks remain VFR at the outset, though the onset of precipitation may introduce some MVFR ceilings starting at 15Z. Wind will veer from SW to NW with time, and gusts to between 20 and 30 knots are likely at all TAF sites, as indicated in the official forecast. Precipitation chances are expected to end by 00Z with a return to VFR conditions, except at FKL/DUJ, where a delay is possible. Sunday night into early Monday, we will see an increase in rain and restrictions. However, VFR conditions and gusty wind will likely prevail for the remainder of Monday, leading to intermittent precipitation and restriction chances through the upcoming week.
No watches, warnings, or advisories have been issued for Pennsylvania, Ohio, or West Virginia, reflecting a relatively mild weather outlook.
