Despite claiming it made him 'chuckle' he took to his personal blog to label it 'sour', 'yawn-inducing' and 'pointless drivel'.
Well, if anyone knows pointless drivel when he sees it...
The 'yawn-inducing' insult is curious, too, given he's been following Tabloid Watch on Twitter since 6 November 2011.
Apart from those insults, Rao had nothing to say about the post. He didn't challenge or debunk it in any way - he just indulged in petty name-calling.
Twenty-eight people decided to post comments in response to Rao's outburst - every one is critical of him and challenging him to point out where this blog was wrong. He hasn't responded on his blog, but tweeted:
Chuckling at how many people have so much to say that they are unwilling to put their names to. Carry on chaps.
So let's look at Nathan's articles about the possibility of a White Christmas in 2012.
On 21 November, the Express said:
Britain is on course for a White Christmas with snow likely as far south as London, say forecasters.
Much of Britain can expect its snowiest winter for 100 years, according to James Madden, forecaster for Exacta Weather.
On 7 December, Nathan went further - a White Christmas was not just 'odds-on' but a 'dead cert'.
Less than a week later, the prediction changed to a 'wet Christmas'.
By 22 December, the Express had decided Christmas Day 'won't be a white-out' and on the big day, the paper reported:
Hopes of a white Christmas have been washed out
And the Met Office's verdict on Boxing Day about a White Christmas?
Some 'dead cert'.
And yet another blemish on the record of - ahem - 'unmatched' and 'accurate weather updates' from Rao and the Express.
