How long will the snow stay?

we have gotten continuous snow fall since 2 A.M. We probably have 6"+ by now, and it should be finishing up in the next few hours. I live in Dallas-FortWorth area, Metroplex, and we've had a lot of fun in the snow. There has been cloud cover all day, and anywhere for 30-34 degrees. Today, around 11 AM the temp will start rising up to (high of,) 41 degrees. (Not sure of cloud coverage though for daytime,) how long do you think the snow will stay? I just dont really want it to melt too early cause we wanted to play more in the snow tomorrow! Ha ha lol, its rare for us Texans to get snow! Especially in February!
