Drought summary per National Drought Mitigation Center:

The West
Stormy conditions hammered both the Southwest and Northwest. Heavy rain
arrived in the Southwest on the last day of November. Daily-record
rainfall totals for November 30 included 1.23 inches in Phoenix,
Arizona, and 2.00 inches in Vista, California. The storm boosted the
year-to-date rainfall in Phoenix from 2.73 to 4.01 inches. Elsewhere in
Arizona, Mount Lemmon (near Tucson) netted 4.80 inches of rain in a
24-hour period on November 30 - December 1. In Blythe, California,
where 1.04 inches fell on November 30, the storm accounted for more
than one-quarter of the normal annual rainfall of 4.02 inches. Farther
north, 25 inches of snow blanketed Brian Head, in southwestern Utah.

Improvements of up to one drought category were fairly common across
the Southwest. For example, severe drought (D2) replaced the large area
of extreme drought (D3) previously covering southern California and
western Arizona. Drought was also scaled back elsewhere in the
Southwest, particularly in Arizona, western Colorado, and southern
portions of Nevada and Utah.
