Share 'Playa weather forecasting... "roll-of-the-dice" this time of year??? Or just plain sunny!'

Greetings my new found playa loving friends... While there's very little that can keep me from getting excited about my trip, I do have 1 question.... Is it hard for weather services to forcast weather in PDC? Since I've known I've been going, I can't seem to help myself from checking the forcast everyday... And depending on which one you check... ie: accuweather, weatherundeground or weather....
