Giving it some though, the reporter from the weather channel is playing this all wrong IMO.
He should come out and admit he made a mistake in judgement, and swear something like this will never happen again.
The reported has made some tweets about the weather after his news broadcast, but has failed to mention or address what was seen on TV, and the station made it worse by saying he was on grass and he was tired (really a lame excuse).
I get it, both the channel and reporter hope it blows over (no pun intended).
Thing is, with social media the way it is today, he's not having much luck so far, granted it's only a short time after the fact, but the longer you wait, the worse it can get IMO.
What is disappointing is the reporter is a "legitimate" meteorologist who has been reporting for the weather channel for like 20 years or so. Don't address it, make an apology ASAP and hope it gets put behind you, not certain how long he can stay in his line of profession until he becomes a joke.
