this happens about every 10 years . between earth wobble and solar shifts it lets the jet stream dive into texas . while this one went further south than usual it is not uncommon . in 84 we had solid snow/ice and 0 degrees . my shop froze up solid.
gotta be prepared for this stuff . we head into winter with full tank of propane , 2 cords of wood , plenty of food and generator ready to go .
hell we got enough tp to poop for 6 months
