Snow in Texas in March?

So we're driving home from New Orleans on Monday night, and its raining the entire way home.

When we get to Mesquite, I notice that the rain is no longer rain, but Snow. Not bad, though, it doesn't seem to be sticking.

20 minutes or so later, we're in Plano, and that's where it starts to get interesting. Snow is sticking to the grass, and the roads seem to be getting "slushy". Time to slow down.

15 minutes later, we're passing through McKinney. As soon as we're clear, all traffic comes to a standstill. The snow is coming down hard. Cars all around us are coated with it. We are stuck on Central Expressway for almost an hour! And this is March!!! Take that, Al Gore!!

We finally made it home around 12:30 in the morning, and this is what we found in our front yard.

UPDATE: All the snow melted on Tuesday, but on Thursday, we got more! And on Friday it all melted again, though there are rumors we'll get more this weekend. Global Warming, sheesh! Give me a break.
