Welcome to the weather blog - a regular Monday through Friday discussion of the weather ! While the discussions usually will only come on days I ' m working , I 'll issue special updates when the weather warrants . I will always post to let you know when no discussion is expected if I ' m away on vacation , etc . - if no update is here and no info is available , that likely means the server has temporarily gone on the fritz and I will update as soon as technically possible .

Question: Why is the speaker committing to run this blog about the weather ?
They get a thrill out of sharing their interests with others , and this is the perfect format
