Snow, Lighting and Hail, Oh My

I have now officially seen the weirdest weather ever. My parents are in town for the weekend and my dad had gone outside to get some fresh air and he started babbling about seeing lightning. My mom and thought he was crazy or just kidding around. It had started to snow and we both were thinking, no way lighting and snow. BUT about 5-10 minutes later, boom lightning again! Then as we got in the car to take them back to their hotel, we realize it is hailing, while snowing and lightning! How bizarre!
