After the two months of dry and sunny weather due to mostly upper level ridging in place across much of Alaska, the pattern flipped for the second half of the month to more of an upper level trough as the upper level ridge shifted to the east. This resulted in multiple storm systems moving into Southcentral with rounds of heavy rainfall that resulted in small streams and river rises in the area.
