Jingle Bells vs Thunderstruck

"Get a fire permit!" That was the advice that the RCMP officer gave us at work today. Intrigued? You should be.
I'm working at an acreage out near Strathmore (about 30 mins east of Calgary). While I was in the basement of the house working on drywall, our boss went outside and decided to burn some fire. I think the plan was to just burn off some of the overgrowth because the lawn and grass hadn't seen much upkeep for some time. A while later, he came back inside and told us to go outside and get around to the one edge of the fire to keep it under control, to make sure it didn't jump the road. It shouldn't have been near the road, but the wind blew it that way. It was a very swirly wind.
The fire was going pretty good, and it was up to the road at one point, but it never did get over. We managed to beat it back, and then we heard a roll of thunder. It rained for about three seconds, and then turned into a large snow. It wasn't snowing individual snowflakes, but tiny little snowballs. It was pretty cool.
The fire was then extinguished where we were, and we went over to our boss about the same time as the arrival as the fire truck. We went back inside and let our boss deal with the fire crew and the RCMP guy. It was a fun day at work. We had a thunder-blizzard.
