MMouse, there is a lot of mumbo-jumbo there but if you wade through it you can get rainfall forecasts (amount) in 6 hour blocks. The forecast is for 3 days (thats why there is 12 rainfall amounts) and is updated daily. You also have to put on your Captian Marvel Decorder ring and figure out the Names. I listed 3 that I know. Helpful info when knowing How wmuch rain is expected. Good Luck.
