Here’s a great resource for pre-flight weather. This NOAA map depicts live aviation weather for North America. You can get a good picture of what the current weather condition are before your flight. All you have to do is hover over any one of the symbols with your mouse and a little window will pop up with all the current weather conditions for that location.
Most of you probably know about this map or already use it, but there are quite a few people out there that don’t know about all the free resources offered to them by the U.S. Government. I’ll be posting more about flight planning resources very soon.
