I just want to add one more thing to the excellent tips already posted by others. OP, it probably won't be of much use to your now, but later on it becomes quite handy.
Local knowledge.
If you are at home and are not sure what conditions are like, ring a pilot or flying organisation who is at the airport and ask them directly. It's also good if you are flying cross country to call a local pilot at your destination and ask them what they expect the weather will do because you'll get information that is pertinent rather than a bunch of numbers and charts you have to interpret.
