It’s been awhile since Los Alamos County has experienced May weather as wet as it did last month. It’s been 23 years, to be exact.
The last time the county has seen that kind of rain was in 1992. Los Alamos County got nearly 3 inches of rain in some spots, that according to Los Alamos National Laboratory weather reports.
May 2015 ranks as the ninth wettest on record, according to the lab.
According to LANL meteorologist Jean Dewart, the meter at Technical Area 6’s weather station recorded 2.80 inches, which was a little more than double the long-term average of 1.39 inches in May.
The biggest totals, however, were recorded at TA-49 and TA-53, as well as in White Rock. At TA-49, near Bandelier, the total was 3.11 inches and at TA-53, near the Los Alamos Airport, the measurement was 3.30 inches.
The TA-54 gauge near White Rock received 2.92 inches last month, which was nearly triple that of a typical May.
Dewart said since last month and May 1992 there have been eight Mays that have seen a quarter-inch of rain or less.
Since January, Los Alamos has received 6.61 inches, 20 percent higher than the townsite’s long-term average and White Rock has received 6.06 inches, nearly double that of what is typical year-to-date.
Temperatures, however, were off slightly last month. High temperatures were 5 degrees below normal in May and overnight lows were 1-2 degrees below normal.
Dewart said there is currently a weak El Niño sea surface temperature pattern in the equatorial Pacific Ocean, although Dewart also said that pattern is likely to strengthen through the end of the year.
The Climate Prediction Center said that could bring above-average precipitation for this month and throughout the summer. Temperatures are predicted to be about average or slightly below.
May’s high recorded temperature was 77 degrees on May 1, which is the warmest Los Alamos has seen through May 31.
Temperatures are expected to be in the 80s Wednesday and Thursday around Los Alamos.
