Pittsburgh residents may want to keep their umbrellas close at hand, as the National Weather Service in Pittsburgh forecasts a weather pattern that could bring periodic showers and thunderstorms through the rest of the week. According to the latest advisory, there is a potential for scattered to numerous storms to develop until this evening, with the main concerns being lightning and localized flash flooding.
The near-term outlook through tonight suggests a "shortwave progression east will generate scattered to numerous storms through this evening," as noted by the National Weather Service Pittsburgh PA in their area forecast discussion. Limited heating from the sun, due to cloud cover, should keep atmospheric instability below severe levels, although flash flooding in urban areas or locations with multiple rounds of heavy rainfall could occur.
Looking forward to Wednesday and Thursday, the weather service emphasizes low probability flood threats with the possibility of severe weather being conditional and highly dependent on the evolution of upstream convective systems. The main takeaway for these days is the chance for periodic showers and thunderstorm activity with temperatures slightly above normal.
For travelers and those in the aviation sector, the weather service projects MVFR cigs are expected to develop by mid-morning with scattered showers with visibility potentially restricted by downpours. Overall, periodic flight restrictions are likely with the scattered showers and storms expected throughout the week.
