There must be a big storm over the Mediterranean that could get a hankerin for some Portuguese Kale Soup and then before you know it, its sucked out into the Atlantic into a ginormous negatively titled trough covering the entire North Atlantic. I know this sounds crazy, but what if it then feels the gulf stream? Then what? Does it get pulled even further west towards the benchmark? And it brings a quadruple phasing of Mediterranean, Adriatic, Gulf, and Atlantic moisture. I think there's a record of something similar happening on Pangea, before it all split apart, only there was less moisture involved so this would be a bigger record setting storm of multiple feet every day
