I don't think PennyHD even read this article.
She just posts her mindless babble over and over.
So my post is addressed to someone with a brain...
Anyone heard the expression too cold to snow?
This article explains that in more detail
“As Trenberth explained, the ideal temperature for a blizzard is just below freezing -- just cold enough to crystalize water into snow. Below that, the atmosphere's ability to hold moisture to create those snowflakes drops by 4 percent for every one degree Fahrenheit fall in temperature.
"In the past, temperatures at this time of year would have been a lot below freezing," Trenberth said. In other words, it's been too cold to snow heavily. But that may become less of an obstacle for snow in the Northeast.
In addition to warming the air, climate change is adding moisture to it.“ http://www.huffingtonpost.com/2013/02/08/clim...
