So the official definition of Partly Sunny, according to the NWS: (sounds like your sky conditions do NOT match the stated criteria)
The NWS definition states that between 3/8 and 5/8 of the sky is covered by clouds when it's classified as partly cloudy or partly sunny. Sometimes, a "mix of sun and clouds" is used by some forecasters instead of "partly sunny" during the daytime hours, though it is not an official NWS term.
