1. Weather Forecasting The national weather service was correct. They showed different forms of what was going to happen in the weather forcast for that 48 hour period. Attached in the slides are the data for the imagery of what happened in the weather during the 48 hour period that I chose. Each map is different and well show what different things mean and how to read them. I think the nation weather service was very helpful and helping me find maps and showing me what was coming.
