Storm – precursor or remnant?

A loud soughing in the trees
Wakes us early
A storm precursor with 
Sudden intensity 
Straining  branches  which bend and rock
Leaves are wrung out like
Handkerchiefs on the line
Falling
Mist cloakes- a wall of white 
The wind buffets the house
Until a sudden stillness
As it drops.
The veil is lifting 
Then it starts over
With a lion’s roar.
