As Pittsburgh braces for a wet weekend, the National Weather Service in Pittsburgh has detailed what the locals can expect weather-wise through Monday. According to the latest NWS forecast, the city is set to experience rounds of showers and the occasional thunderstorm, with the greatest chances for severe weather occurring Sunday afternoon. This morning, isolated showers have been sparsely dotting the region, but with minimal upper-earth support, widespread coverage should not be anticipated.
For those venturing out this afternoon or evening, it's worth considering strongly keeping an umbrella close by as there is a low probability for severe storms that could bring strong winds and even flash flooding. "The primary threat with any stronger storms will be damaging wind," the National Weather Service Pittsburgh reported. Diurnal heating is expected to be more significant today compared to Friday, which might lead to storms that could interrupt your Saturday evening plans.
Looking ahead to Sunday, more widespread thunderstorm development is predicted due to the lingering upper low/trough to the north. These conditions could provoke on-and-off storms throughout the evening. However, the threat level seems dialed back as the lack of strong instability is predicted to mitigate any flood threat. Come Monday, cooler temperatures are forecasted, along with residual showers tapering off by Monday evening, such as daily highs dropping to a cooler, seasonally appropriate 60s to lower 70s range.
As for the skies above, aviators should anticipate primarily MVFR conditions with chances for IFR at FKL/DUJ due to this morning's status. Post-sunset, there's an uptick in the probability for cloud ceilings to lead to additional MVFR and potentially IFR restrictions.
For now, Pittsburgh has no watches or warnings in place, a bit of solace before the rain picks back up. Just in case, be prepared with your rain gear, and keep an eye on the skies if you plan to be outdoors.
