Winter Weather Reporting

Citizen science and their reports are important to meteorologists across the weather enterprise. This includes reports of precipitation type. The mPing app is a way to do that. These observations of precipitation type plot directly on our workstations at the NWS offices, and we can use that to better assess the current state of the atmosphere and its impacts, and adapt our forecast and impact-based messaging as needed.
