One of two things is going on here. This local news anchor and weatherperson CLEARLY don't like each other. OR it's all an act and they're really bad at it since neither one of them is very clever or funny enough to pull it off. I'm leaning towards the former, although the lack of wit still applies here.
One thing I'm sure of; there's probably a fair amount of people tuning in each morning to watch the light verbal cat fighting these two are doing.
