NOTE ON THE IMPACT OF COVID-19 ON WMU SNOWFALL
MEASURMENTS: Snowfall measurements at Western Michigan
University ceased on March 21, 2020. Any snow that fell after
that date was measured from where I live, which is on the east
side of Kalamazoo. Reported totals may therefore not reflect what
actually occurred at WMU.
Notes:
Snow depths (in inches) are reported for 11:59 p.m.
"Normal" values are seasonal averages based on the
last 22 winter seasons for Western Michigan University.
The seasonal snowfall average for the entire season is 77.3
inches.
Any measurements that are posted before 11:59 p.m. are not final
and are subject to change.
