Plot Description:

This chart presents year to date accumulated precipitation for a station of your choice. The year with the highest and lowest accumulation is shown along with the envelop of observations and long term average. You can optionally plot up to three additional years of your choice.

You can specify the start date (ignore the year) for when to start the 365 day accumulation of precipitation. The year shown is the year for the start of the accumulation period. For example, if you accumulate after 1 October, the year 2020 would represent the period from 1 Oct 2020 to 30 Sep 2021.

Accumulating snowfall data is frought with peril, but this app will let you do it! The app has a tight requirement of no less than 3 days of missing data for the year to be considered in the plot.

Based on a sampling of recent timings for this application, plot generation time has averaged 7 seconds. Hold on for the plot is generating now!
