Cold fronts are important because they contain lightening... as a big fan of the Intellicast.com service on line I thought the app was just as good as one can determine from an app in the field when to take cover or get back to the car... When a storm approaches and the map shows the storm in Lancaster and is moving 15 miles per hour, I have 15 minutes to 30 minutes to get back to the car or get out of the park. Imagine my surprise when the storm didn't match the Smart Phone... Intellicast has a delay or buffer on the data!
I just solved the issue - The Weather Channel app doesn't have a delay and its very up to speed from installing!
