Are the "polar vortex" and "cut-off lows" over/near the Great Lakes new phenomena?

In recent years, I've heard weather reporters describe "cut-off" low pressure systems which park over Southern Ontario for days at a time. In summer months, they bring us long stretches of cool... more

Is there a seasonal difference in the average cloud floor?

It always looks like clouds are so much higher in the sky (altitude) in the summer than in the winter. Is that true? If not, is there some sort of optical illusion? If so, why is that? I live in... more
