Minimum temperature — and what happens below it

Minimum survivable temperature is roughly below about −20 °C. Weeping Norway Spruce is built for winter — once established it takes hard frost and snow in its stride.

Concretely, for weeping norway spruce as it gets too cold:

It tolerates winter lows to about −20 °C once established.
Below its rated zone, the visible damage is browned or blackened top growth and, in the worst case, a killed crown or root.
First-year, newly planted, or container-grown specimens are noticeably less hardy than established garden plants — the roots are exposed.

Can weeping norway spruce go outside or overwinter — and where?

Plant it out within USDA 3-7 (very cold-hardy outdoor conifer) and it overwinters with little or no help.
It does not want to come indoors — a warm winter room actually weakens a hardy plant by denying it dormancy.
The real risks in its range are waterlogging, wind-rock on young plants, and a late hard frost on new growth — not ordinary winter cold.
