Monsoon 2020: Drier than Average or Historically Dry?

Monsoon precipitation for Arizona and New Mexico is below average in most of the region (Fig. 1). Precipitation to date at regional stations (Fig. 2) and fewer days with rain (Fig. 3), both illustrate features of a relatively dry monsoon. There is still time in the monsoon window, and the rest of August and September will determine just how dry the 2020 monsoon turns out to be.
