I would agree with Debiassi and Rocket route is a fantastic flight planning programme especially IFR.
One word of caution using any predictive icing forecast is that icing is very hard to predict so only use these predictions as a guide.
I have taken off in a jet with predicted icing climbed up through 20 k of solid cloud and picked up nothing.
Other times I have picked up quite a lot of ice in the most unsuspecting conditions so beware.
Use everything to hand to get a broad picture but most of all use experience and good airmanship in avoiding and dealing with the stuff.
if your flying a non ice capable single be extra cautious and aware that you can come down and loose the ice above MSA if you are stuck with the stuff to ground level do not go!
