Are you truly claiming that any set of antipodes has the same weather?

So, Monday morning when Minneapolis (45N, 93W) was in the middle of
a nine-inch snow storm, the island of Bali (45S, 87E) was in the
middle of a 23 cm snow storm as well? The temperature here was
about 20F. Was Bali having temperatures of -7C? Over the next few
hours, as the sun rose here, it warmed up. Was it simultaneously
warming up in Bali as the sun set? I'm sure that they were glad
of that; -7C would probably seem like an extremely cold temperature
to them.

I wonder what's going to happen tomorrow morning (Minneapolis time)
when we get down to around -10F.
