Being a part of the CoCoRaHS Project gives us a great insight to how much and where rain fell. Each day the observers who volunteer their time with CoCoRaHS log in to the site and record their rainfall (sometimes it is snow, sometimes it is hail). We also have space to add in some comments. CoCoRaHS is an acronym that stands for: Community Collabrative Rain Hail and Snow Network.
Be sure to check out the site and you'll see how much rain fell at an observer's location.
For Tennessee, the place is to go is HERE. We have around 350 observers who are faithful nearly every single day.
If you're impatient and want to know how much rain fell RIGHT now and don't want to wait for the CoCoRaHS observer reports (which start coming in about 6 am each morning), you can go to the Weather Underground site here. There you can key in your ZIP CODE and see several personal weather stations for your area (down toward the bottom of the page).
My Weather Underground area is located here.
My Weather Station live is located on this page to the right OR all the way at the bottom.
