L train back all weekend?

There was a lot of weirdness with scheduled diversions. I subscribe to alerts from mta.info for the lines I use and get e-mails each Friday with any diversions planned for the weekend. This week, for the first time, I first got an e-mail with scheduled diversions but with this caveat:

Due to adverse weather conditions some diversions listed below may be canceled.

.
Then I got another e-mail saying:

ADVISORY UPDATE: This email reflects work that has been canceled due to cold weather conditions for the weekend of Feb 3 - 4, 2007.
