Monthly Precipitation and Temperature: November precipitation was average to below average across most of Arizona and New Mexico (Fig. 1a). November temperatures were above average to much above average in most of Arizona and New Mexico (Fig. 1b), with a pocket of record warm conditions in west Texas. The daily average temperature anomalies for Nov. 1 – Dec. 12 (Fig. 2) highlight the fluctuations at select stations around the region.

Sea surface temperature (SST) forecasts for December through February call for below normal conditions across the equatorial Pacific (Fig. 1), extending the trend of the last 3-4 months (Fig. 2). International climate outlooks describe La Niña conditions as forecast to remain a La Niña event through winter 2020.

Monthly Precipitation and Temperature: October precipitation ranged from record driest to below average in most of Arizona and from below average to above average in most of New Mexico (Fig. 1a). October temperatures were above average to record warmest in Arizona and near average to record warmest in most of New Mexico (Fig. 1b). The daily average temperature anomalies for Oct. 1 – Nov. 15 (Fig. 2) highlight the fluctuations at select stations around the region (see detailed station data).

Sea surface temperature (SST) forecasts are for below normal across the equatorial Pacific (Fig. 1), extending the trend of the last 3-4 months (Fig. 2). International climate outlooks describe La Niña conditions as likely to remain a La Niña event through winter 2020.

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

Monthly Precipitation and Temperature: August precipitation ranged between record driest and below average in most of Arizona and New Mexico (Fig. 1a). August temperatures were record warmest in all of Arizona and much of New Mexico (Fig. 1b). The daily average temperature anomalies for Aug 1 – Sept 15 (Fig. 2) highlight the fluctuations at select stations around the region, including the very warm temperatures in most of August and early September, as well as the steep drop in temperatures across the Southwest in the second week of September.

Sea surface temperature (SST) forecasts show cooling across the equatorial Pacific (Fig. 1), extending the pattern of the last few months (Fig. 2). La Niña conditions are now considered to be present by most major outlooks. These conditions are forecast to remain a La Niña event through winter 2020.

Sea surface temperatures (SSTs) continue to cool across the equatorial Pacific (Figs. 1-2). Conditions are forecast to remain ENSO-neutral through summer 2020, while seasonal outlooks point to an increasingly likely chance of a La Niña event by fall or winter 2020.

Monthly Precipitation and Temperature: July precipitation ranged between record driest and average in most of Arizona and between below average and above average in most of New Mexico (Fig. 1a). July temperatures were much above average or record warmest in most of Arizona and New Mexico (Fig. 1b). The daily average temperature anomalies for Jul 1 – Aug 15 (Fig. 2) highlight the fluctuations at select stations around the region.

Sea surface temperatures (SSTs) are cooling across the equatorial Pacific but are still mostly in the range of normal (Figs. 1-2). Conditions are forecast to remain ENSO-neutral through summer 2020, while seasonal outlooks point to a possible La Nina event by fall or winter 2020. (Read More)
