Sea surface temperatures (SSTs) are near normal across most of the equatorial Pacific (Figs. 1-2). Conditions are forecast to remain ENSO-neutral through summer 2020, while some outlooks point to a possible La Nina event later in 2020.

Monthly Precipitation and Temperature: May precipitation ranged between record driest and average in most of Arizona, and between much below average and average in most of New Mexico (Fig. 1a). May temperatures were above average in nearly all of Arizona and New Mexico (Fig. 1b). The daily average temperature anomalies for May 1 – Jun 14 (Fig. 2) highlight the fluctuations at select stations around the region.

Sea surface temperatures (SSTs) are returning to near normal across the equatorial Pacific (Figs. 1-2). Conditions are forecast to remain ENSO-neutral through summer 2020, while longer term outlooks point to the possibility of a La Niña event later in 2020.

Monthly Precipitation and Temperature: April precipitation ranged between below average and above average in most of Arizona and between much below average and average in most of New Mexico (Fig. 1a). April temperatures were above average in most of Arizona and much of New Mexico (Fig. 1b). The daily average temperature anomalies for Apr 1 – May 20 (Fig. 2) highlight the fluctuations at select stations around the region.

There are positive sea surface temperature (SST) anomalies across the equatorial Pacific (Figs. 1-2). Forecasts expect conditions will stay within the range of ENSO-neutral through at least summer 2020, with hints at a possible La Niña later in 2020.

Monthly Precipitation and Temperature: March precipitation ranged between average and record wettest in Arizona and between below average and record wettest in New Mexico (Fig. 1a). March temperatures were average to much above average in Arizona and above average to much above average in New Mexico (Fig. 1b). The daily average temperature anomalies for Mar 1 – Apr 14 (Fig. 2) highlight the fluctuations at select stations around the region.

Positive sea surface temperature (SST) anomalies remain in the equatorial Pacific, particularly in the western regions (Figs. 1-2). Despite lingering warm waters, forecasts expect overall conditions will stay in the range of ENSO-neutral through at least summer 2020.

Monthly Precipitation and Temperature: February precipitation ranged from below average to much below average in Arizona and New Mexico (Fig. 1a), while February temperatures were average to above-average across nearly all of Arizona and New Mexico (Fig. 1b). The daily average temperature anomalies for Feb 1 – Mar 18 (Fig. 2) highlight the fluctuations at select stations around the region.
