Pittsburgh might see a dry spell during the day, but it's packing an umbrella for the night. According to a report from the National Weather Service Pittsburgh PA, the region is under the influence of high pressure, which is expected to keep the weather dry till later this evening. But don't get too comfortable, as scattered showers and thunderstorms could gatecrash your plans tonight and into Wednesday with a weak cold front on the horizon.
Rolling up the sleeves of forecast details, the Weather Service indicates that clouds will likely increase later this evening with an approaching disturbance from the west. Those hoping for a refreshing downpour might find the odds stacked against them, as the increasing clouds might only tease isolated light showers in eastern Ohio and near the Lake Erie area late in the evening. An elevated layer of dry air might play spoilsport and lead to precipitation evaporating before it can reach thirsty grounds.
Wednesday is playing a similar tune, with scattered rain chances ticking up overnight ahead of the trailing cold front, expected to fizzle out by Wednesday afternoon. If you're terrain-bound, you might see some showers linger. But don't expect to wrestle with an umbrella; the rainfall amounts are projected to remain low. The Weather Service's discussion points to a 60% probability for any location to receive more than 0.25 inches of rain, with the best chances north of Pittsburgh.
Looking further ahead, the weekend could bring above-average temperatures to the region. As we turn the page to Saturday and Sunday, another cold front could make a cameo, potentially stirring up precipitation. But hold off on the rain dance, as the forecast shows rainfall amounts this far out look paltry at best. The extended gaze of the Weather Service hints at a drop in temperature as next week rolls in, keeping the mercury below average for an early taste of the fall.
For those with an eye in the sky, aviation forecasts suggest afternoon cloud bases hovering around 5-7kft. Winds are going to veer more southerly, tightening up a bit ahead of the said weak low pressure. The overall outlook from now till Saturday seems favorably dominated by high pressure, ensuring the return of VFR conditions and a snag-free end to the week.
No watches, warnings, or advisories are in place for PA, OH, or WV at this time, keeping the safety gears at rest, at least for now. Stay tuned to local updates to keep abreast of any quick shifts in the weather patterns of Pittsburgh.
