Now, obviously, this is all just a glitch in Dark Sky's system. The company explained the error to Mashable:

"The root cause of the strange temperature forecasts was a single faulty forecast generation server that was generating wacky results. Normally this would be caught by our monitoring and not making it into our published data, but the issue somehow made it through our checks. Fortunately we were able to fix it, and improve the checks to make sure it doesn't happen again."

Great news that hell is probably not actually going to freeze over. But on the off-chance that the end of the world is nigh, you might want to grab with an extra coat or seven on Saturday.
