How Would You Rewrite This Urgent Leave Request Memo for a Family Emergency?

Greetings,

I am blogging this memo as I just wrote it for a member of this community. Tell us how you would write it differently:

This is to request you to grant me a day's leave tomorrow. Please consider this as I need to be with my family due to an urgent requirement. I will be available via emails and phones.
