There was a flurry of photos of Asperitas clouds today on the Pennsylvania Weather Watchers group on Facebook. Asperitas clouds are new, at least as far as their official recognition, which I talk about in this AccuWeather story.
The clouds in some cases were accompanied by virga (precipitation which is falling but not reaching the ground) which is not a surprise, since they essentially represent the edge of the precipitation.
The photos above were taken in Mercer County by Donald Martin; below by Laura Kosht at Moraine State Park, PA, and below that, New Castle, PA by Renee Krasinski.
They occurred, as they often do, on the edge of a group of storms where dry air meets moist air, and they were sighted in and around Mercer County, north of Pittsburgh (encircled on the radar/satellite map below).
These shots were taken from the WeatherSTEM cameras in Pittsburgh:
The animation below shows a time-lapse of the Asperitas clouds on the Pittsburgh camera:
By the time the clouds reached State College this afternoon, they weren't nearly as impressive, but still fun to watch as these WeatherSTEM camera timelapses show:

This storm didn't qualify as a "bomb cyclone" like the one in March, but it sure had some crazy weather.

Next week's cold outbreak is not unlike the ones in early March 2014 and 2015 but not quite as severe.

It's time to update my list of world wind records again after a massive storm swept Hawaii's highest mountain.
