View maps for mean annual snowfall, mean seasonal snowfall, and mean snowfall during the snow accumulation season (SAS) over four time periods between 1890 and 2000.
Mean Snowfall, Annual
1890-2000
Mean Annual Snowfall, 1890–2000

Mean Annual Snowfall, 1911–2000
Mean snowfall for the July–June period based on monthly totals from 1911–12 to the 1999–2000 seasons.
1941–2000
Mean Annual Snowfall, 1941–2000
Mean snowfall for the July–June period based on monthly totals from 1941–42 to the 1999–2000 seasons.
1971–2000
Mean Annual Snowfall, 1971–2000
Mean snowfall for the July–June period based on monthly totals from 1971–72 to the 1999–2000 seasons.
How These Maps Were Made
Mean Annual Snowfall: How These Maps Were Made
For each annual snowfall year (July–June), one gridded map was generated based on the individual station observations using a kriging technique. Means for a given period length were then computed based for each gridpoint value rather than a per-station basis. This sequence allows for use of all possible data in a given year.
Mean Snowfall, Seasonal
1890–2000
Mean Seasonal Snowfall, 1890–2000
Mean snowfall for the October–March period, based on monthly totals from 1890–91 to the 1999–2000 seasons.
1911–2000
Mean Seasonal Snowfall, 1911–2000
Mean snowfall for the October–March period, based on monthly totals from 1911–12 to the 1999–2000 seasons.
1941–2000
Mean Seasonal Snowfall, 1941–2000
Mean snowfall for the October–March period, based on monthly totals from 1941–42 to the 1999–2000 seasons.
1971–2000
Mean Seasonal Snowfall, 1971–2000
Mean snowfall for the October–March period, based on monthly totals from 1971–72 to the 1999–2000 seasons.

Mean Seasonal Snowfall: How These Maps Were Made
For each snowfall season (October–March), one gridded map was generated based on the individual station observations using a kriging technique. Means for a given period length were then computed based for each gridpoint value rather than a per-station basis. This sequence allows for use of all possible data in a given year.
Mean Snowfall, Snow Accumulation Season (SAS)
1890–2000
Mean Snowfall over SAS, 1890–2000
Mean snowfall for the period between the onset and end dates of the snow accumulation season, based on monthly totals from 1890–91 to the 1999–2000 seasons.
1911–2000
Mean Snowfall over SAS, 1911–2000
Mean snowfall for the period between the onset and end dates of the snow accumulation season, based on monthly totals from 1911–12 to the 1999–2000 seasons.
1941–2000
Mean Snowfall over SAS, 1941–2000
Mean snowfall for the period between the onset and end dates of the snow accumulation season, based on monthly totals from 1941–42 to the 1999–2000 seasons.
1971–2000
Mean Snowfall over SAS, 1971–2000
Mean snowfall for the period between the onset and end dates of the snow accumulation season, based on monthly totals from 1971–72 to the 1999–2000 seasons.
How These Maps Were Made
Mean Snowfall over SAS: How These Maps Were Made
Since exact dates, rather than months, delimit the snow accumulation season, the technique to generate these statistics incorporated whole month and partial-month snowfall totals. Whole month snowfall totals (Dec., Jan., Feb.) could be used for all stations, however a weighted fraction of the monthly snowfall was used when the onset and/or end date fell within a month. This fraction was based on the number of days in a particular month that was included in the snow accumulation season. Therefore, since the snow accumulation season is variable throughout the state, snowfall totals must be compiled from unequal time periods for each station.
For each value of total snowfall over the snow accumulation season, one gridded map was generated based on the individual station observations using a kriging technique. Means for a given period length were then computed based for each gridpoint value rather than a per-station basis. This sequence allows for use of all possible data in a given year.
