Answer 1

Wow.  Do you have a whole semester? :-)

It's a pretty complicated explanation so hang with me.

Air masses move around on the planet.- mostly because the earth doesn't heat at the same rate all over.  Warm air rises.... cooler air sinks, etc.  It' moving all over the globe all of the time

I live in the US in the state of Virginia.  The situation you described has just happened here.  It was VERY hot Monday and Tuesday.  Today, a big air mass from Canada  moved south.  Because Canada is so much cooler, the air that has been there is cooler too.  It's drier too.

So today we're enjoying air that was over Canada last week.  But who knows.... we may have air from the Gulf of Mexico move in tomorrow.  It would be hot and damp.
