Snow, and more snow

Are you sick of the snow? We are too! Up until February this year, much of Minnesota was experiencing a rather brown winter. Light snowfall events here and there, and then the sun would melt it away within days. Now, much of Hennepin County is sitting with anywhere from 10 to 18 inches of snow on the ground. A month ago we weren't concerned about spring flooding due to the lack of snow, but now we are due to the amount of snow pack we have. On February 20th, we had a winter storm hit the county and leave about 7-8 inches of snow after one day. Below are a couple graphs depicting our snow depth, snowfall, and snowfall rate from that storm. This data is measured by our snow depth sensor. It is a sonic distance sensor, that measures the difference in height from when the sensor was installed without any snow on the ground, to the height of the snow now. We can use this data to calculate our snowfall during a storm, and our snowfall rate every hour.
