What's the difference? A question that always popped into my head but never had an answer. To be honest, I thought it was just a matter of the weatherperson's disposition when they built the report that day.


Partly sunny is a prediction that happens during the day.

Partly cloudy happens at night.

No sun= no opportunity to be partly sunny.

So obvious!

Tell me I wasn't the only one with her mind blown here.
