January 2018 Met Central -

During January there was only a slight reduction in the warm and dry
trend that has been the case through most of this winter. However some
of the coldest days of the winter came during the middle of January
but overall the temperatures ran above normal during the early part of the month
and again at the end. With the continuing dry conditions the daytime
highs again ran mostly higher than normal while the nighttime lows ran
lower than normal. The daily means average temperature ended up just
slightly above normal. Two new daily high temperature and 3 new daily
low temperature records were set during the month.

    January Record Temperatures - High 24.1 (75.4 F), Low -20.7 (-5.3 F)
    January '18 Record Temperatures - High 23.0 (73.4 F), Low -17.8 (0.0 F)

January precipitation was better than November and December but not by
very much. The refuge-wide average was only 2.6 mm. Believe it or not,
there have been 11 drier February's in the pst 29 years.

Albuquerque - Sevilleta Comparison

Albuquerque's 95-day drought was broken on Jan 10th with a mighty 0.03"
rain-fall event at the Albuquerque airport station - 0.07" at my house.
A 2nd storm latter in the month delivered a trace of snow.

Water-year Precipitation

The Sev continues to be off to the slowest start for a water-year in
the SEV LTER 1989-2018 record.

Drought conditions expanded across more of New Mexico during January.
The U.S. Drought Monitor
now rates 68% of NM as under severe drought
conditions. This includes the Sevilleta. 95% of NM is under some drought status.


The La Nina pattern continues. The Sea Surface Temperature anomaly
for the key 3.4 Nino zone ended the month at -0.9. The Ocean Nino
Index (ONI) for the Nov-Dec-Jan period was -1.0, down from -0.9 from
the previous 3-month period.

The Southern Oscillation Index (SOI) went -0.1 in December to +1.1 for
January (a big oscillation) but the 5-month running mean went from
+0.54 to +0.60, a little further into the La Nina zone.

Notables From On and Off the Sev

January was the 10th driest January in NM in the past 124 years.

February Forecast

Off to a very warm and dry start to February which is what NOAA is predicting.
NOAA is predicting a much warmer than normal February with most of the
state expecting less than normal precipitation
