Analysis of Lady Snow

I see Lady Snow
In her lacy frills so white,
On valleys so low
And on mountain of height.

I see Lady Snow
In the day so bright.
Streams no longer flow
And little Sparrows take flight.

I see Lady Snow
Dancing with Mr. Wind at night,
Through the trees they blow
In the sweet moonlight.

Where is lady Snow?
Does anybody know?
Spring has come, so she must go
Good bye Lady Snow!
