Here are the vitals of what was going on at 7:45pm, Thursday, April 10th in Edinboro, when this picture was taken.
Temperature In Charleston, WV (330 miles to the south): Mid 80's
No Precipitation In Either Location
Warm Front About To Lift Through The Region
Knowing the vitals, we can say that these are Stratocumulus Clouds, which tend to form when warmer air (from the south) moves over colder, moist air (in Edinboro). This warmer air lifts as it travels from South to North (this is called isentropic lift). So, the warmer air arrives first in the upper levels of the atmosphere.
As this occurs, you get the bumpy, or rolling texture to the clouds. When it comes to precipitation with these clouds, usually it will be light, like Thursday night. However, stratocumuli usually are observed before, or after bad weather rolls through the area. In this instance, it is before, as some pretty crummy weather will be with us through the weekend.
