Unbearably, inhumanly cold in winter. It can physically hurt to breathe the air there, it's so fucking cold.
I have relatives there
R3 is a delicate flower.
The Twin Cities are great, but they are not for everyone. It's one of the most liberal metro areas in the country and there is excellent theater (the Guthrie) and art (Walker Art Center, MIA). Even the food has picked up in recent years.
It does get cold in the winter, but the worst of it doesn't last that long.
