With Harvey and Irma and the Mexican earthquakes and the recent solar eclipse, it’s often been quoted recently that there will be weird weather before Mashiach comes. This is nothing new for me - I’ve grown up hearing about this Midrash, which has invariably been applied when there’s weird weather. However, when I actually go look for it, I can’t seem to find it. Has anyone heard of this before, and can they refer me to it? Thanks!
