It's really not fair that a day forecasted to be 9 degrees and sunny has started out as minus 2 and sunny. As far as frosty days in March go this is a doozy. I wouldn't plan on warming up any time before 9:00, or even 10:00, or...ugh. Anyway, it'll be a while. Eventually, though, it should be nice out there, so enjoy it when it happens.
