Before we start looking at snow cover maps, I thought we should take a look back at the total amount of precipitation
received across the Prairies over the last growing season compared to historical amounts. From the map
you can see that a huge portion of the agricultural Prairies saw extremely high moisture to record-wet conditions
during this period. Thinking back over the years I don’t remember the last time such a large area was this wet.
