These steps are done by the HOME TEAM only.
2.) Now, pick any team (it can be whatever one comes up automatically) and when the options appear for uniforms, playbooks etc...just advance to the next screen menu. This is where you will choose and enable live weather.
3.) Here you should be on the pregame options screen with a few tiles mid-screen and one of which is The Weather Channel Live Feed. Click on this tile and it will take you to a menu where you can choose Live Feed, random, cloudy, snow etc. Keep it on Live Feed and hit "X" to enable it. I am not sure this is necessary, but it works every time I do it, so I am including it here. After doing this step it will grab the Live Feed from The Weather Channel and put you back on the pregame options screen.
4.) Do not start the game! Now, back out using the "O" (circle) button all the way to the MAIN MENU screen of NCAA 14. Navigate to the "ONLINE" tile and go into the lobby screen. Here you can create the NDL room or join in any lobby. Once you send the invite to your opponent, you will be taken to the "Team Select" screen and you both pick you teams, playbooks, etc. Just ready up and start the game and VOILA! your game will be played in real time and Live Weather!
REMEMBER, THESE STEPS ARE DONE BY THE HOME TEAM!!!!!
