With this application, you can plot COOP observations for a date of your choice.
- Snowfall data is not complete. Please be careful using the data.
- Snowfall depth data only goes back to 1991 for Quality Controled source.
- The preliminary data is for the date the observation was reported and not necessarily for the local date. The reports are around 7 AM, so the high temperature (for example) was most likely for the previous date.
