It doesn't say "cold wind blowing visit" - "a cold wind blowing" is a noun phrase, the complement of "was".
With an adjectival modifier, we can move it to complement position, so
The green door ...
implies that we can say
The door is green.
But, while a noun phrase can sometimes be used to modify a noun phrase, we can't normally use the same noun phrase as complement; or if we can, it won't have the same meaning. So:
The village green ...
*The green is village. (or *The green is a village)
The man is a builder
but not normally
*The builder man ...
"A cold wind blowing" is a metaphor for something unwelcome, or something which suggests that something unwelcome will follow.
