Slang of the Day:1 Devilish Domestic Dispute

This is our time of summer storms: often in the afternoon, often torrential, sudden, brief, usually highly localized.² The storms are often so localized that one can be in the midst of a downpour and see the sun shining a few blocks away — or vice versa. And not infrequently, as the rain pours straight down and the light slopes in diagonally, it rains as the sun shines. I was at a shindig recently, sitting outside with a bunch of folks. The sun was shining. And it started drizzling. And I mentioned, "The devil's beating his wife." This brought puzzled responses from a number of fellow shindiggers. They'd never heard the expression. But back in ol' Virginie (rendered in Appalachian geezer-speak), that's what we said: 

Raining while sunny = Devil's beating his wife. 

I have no knowledge of the phrase's origin (and for the moment, I choose not to Google it). But the pattern of puzzled vs. non-puzzled responses led me to wonder if the saying was regional. Data points:

• We say it in Virginia.
• Memphibians at the party also knew the phrase.
• The Detroiters seemed to be in the "never heard it" camp. (For complex rock 'n' roll reunion reasons, there was a high ratio of Detroiters present.)
• I've heard the phrase here in New Orleans (though it's possible I was usually the one saying it).

A Southern thing? We lack sufficient data for meaningful extrapolation. So I ask you: Do you know the phrase? And where y'at? Slimbo-minions, bring me data!

1 Hey, look! The last "Slang of the Day" was just a couple of days ago. So our micro-series is almost daily. Bi-daily? (That prefix confuses me. Every two days? Then is there another prefix for twice a day?)

2 We get torrential rains other times of year, but the pattern is usually different: organized bands of storms moving west to east, bringing long steady downpours which last for hours. (I'm a bit of a weather nerd, fond of checking the radar.) But these summer storms just bloom up out of nowhere — little yellow, orange, and red blobs — and then shrink away again just as quickly.
