The one that I recall most vividly in this area is the Valentines Day 2014 Cold Front from hell... my wife and I were SUV shopping to replace her old car. She was uber preggers (kiddo born in late March) and we were looking for the new family vehicle. I remember starting the day a lot like today... 60s, nice, sun peeking out... then that front moved through and we were using my old car with bald tires to shop around. We ended the last test drive while the snow was starting and by the time we were done the roads had turned to skating rinks and we were slipping and sliding all over the place trying to get home. We ended up stopping at Victoria's Gastropub in Columbia to wait it out and when we got back on 100 to go home, the shoulders were littered with wrecked cars that had slid off the road.
