June 2017 Met Central - A Warm and Dry Start to Monsoon


June started out a little cooler than normal
but than popped up into
the warmer than normal range for much of the early half of June.
There was an 8-day period from Jun 17 til Jun 24 with temperatures
exceeding the 100 degree F mark somewhere on the refuge. Four of these
were new daily highs. Temperatures dropped back down during the last
eight days of the month which is usually the very hottest time of
June.

    June Record Temperatures - High 43.0 (109.4 F), Low 0.4 (32.7 F)
    June '17 Record Temperatures - High 40.5 (104.9 F), Low 3.2 (37.7 F)>

June moisture came during the first week of the month and then again
during the last week. None of it was really large and none of it was
very widespread. The refuge-wide average was only 4.4 mm which is
well below the June average of 14.5 mm

Albuquerque - Sevilleta Comparison

Albuquerque did better than the Sev entirely due to a single storm on
the 26th that dropped almost a half an inch (12.2 mm) of rain. As is
often the case other parts of Albuquerque saw less than this while
on other days other parts of Albuquerque got measurable precipitation
while the ABQ airport got only a trace or less.

June tied as the 9th warmest June in Albuquerque's 1893-present record.
Last year, 2016 was the 5th warmest June in Albuquerque.

Water-year Precipitation

Sevilleta is still running well ahead of average for the water year
but will need to look for better moisture during the upcoming monsoon
months.

Drought

At the end of June the U.S. Drought Monitor
is classifying about a fair amount of the southern half of NM as "abnormally dry" and the boot
heel region of the state as under moderate drought.


The Palmer Drought Index
paints a different story with more of
southwestern NM considered under moderate drought and the Central
Valley actually qualified as under extreme drought.

ENSO

Currently it seems likely that ENSO will remain in the neutral range
for the coming winter. The Ocean Nino Index (ONI) for the
April-May-June period remained at +0.4

The Southern Oscillation Index (SOI) continues to oscillate going from
+0.3 in May to -0.4 in June. The 5-month running mean holds in the
neural range at +0.1
