Growing season rainfall (April 1 – June 24) amounts have been below average for most of the prairies, particularly across southern regions of AB (Fig. 7). Based on modeled soil moisture (Fig. 8), recent rains have improved soil moisture values across a large area of SK. Predicted soil moisture continues to be low across large regions of eastern MB and southern AB.
