Brand New SnowCast We hope you enjoy our brand new SnowCast graphics. They are located to the right and by clicking on the graphic you can view a larger image of our Day 1 and Day 2 SnowCast maps. SnowCast is a graphic interpretation of our computer forecast guidance. SnowCast inputs guidance from our computer models and then displays a graphic interpretation of where and how much snow will fall across the United States! These graphics are updated 4 times a day automatically. This is just one new feature of our new website and we hope you enjoy!
