Scroll down the page until you see a box on the right side with information about "Today," Tonight," and "Tomorrow." Click on "Today." The website will display hourly information about today's weather forecast for that city.
Repeat the previous steps for the cities you'll pass through on driving trip. Estimate when you'll be going through those areas and write down the predicted weather conditions for those times.
Combine the information you have gathered and you will have a good idea of the road conditions you will encounter and how much time your drive will take.
