What Am I: The Writer's Riddle

I have great destructive power,
if one stays out too long
But I am a necessity, without me,
life would go wrong

I must rest several hours
each day
Allowing my brethren to
come out and play

Gently I caress the
petal of each flower
Awakening the sleepyheads
in the early morning hour

Some days I hide
as the skies weep
Be doughty, I'm still there,
but I may not see you
'til next week...
