Again as usual on Weather Center, they used bumper music for the openers most of the hours instead of the actual opener music, but the one neat benefit is that since they had a really long teaser, they played about 55 seconds of the "hard" theme music straight. (everything except the opener had voiceover, but it still gives us an idea of how the theme sounds as a whole.)
BTW, when I say "hard", there are two main bumper tracks that are used for WC; one is the normal one that's associated with the opener; then there's this "hard" one that uses most of the same notes but with a more intense feel to it. Video to come shortly.
