June provided very little relief from our ever extending drought. During early and mid-June, there were a few minute storms. Then there was a 10-day dry spell before some more sizable shots of rain on the 29th and 30th. Monthly totals across the refuge varied from 3.0 to 14.1 mm with a refuge-wide average of 6.6 mm. While this is still less than half the expected June inputs it was still better than the last two years.
Below are this years entries for the Monsoon Prediction Contest. Predictions were submitted by 48 people. If you really think that you submitted a guess and it is not on the list, please contact me immediately - it could have gotten lost. People's dates and times should be correct as I just copied and pasted them - hence the variety of formats. July 10 was the most popular choice this year with 4 selections. Five other dates had 3 picks each. With high pressure locked in over NM, there seems to be little indication that monsoon will start before July.
Good Luck to all
This report is a little slow to hit the web because Met Central went to Colorado for a couple a weeks to see what green vegetation looked like.
For May moisture, or lack there of, is still the story. There were a few storms that showed some potential but then generally fizzled. Almost all moisture fell on May 9 but only averaged out to 2.2 mm across the refuge. Drier Mays in the past include 1996, '98, '00, '03, '06, '11.
Even though everyone, including NOAA, is being pessimistic about our summer rains, I am going to predict that we will get at least some monsoon-type rains. It should be remembered that the 2006 winter and spring were very similar to this past one and was followed by the wettest summer on record. It's still a little early for the monsoon flow to get set up; the National Weather Service has started declaring that the official Monsoon season begins June 15 but I'm still going to officially kick off the 16th annual Monsoon Prediction Contest.
April temperatures were on the giant roller coaster ride this month. On a weekly harmonic temperatures went from highs in the 80 degree range and within a day or so they had tumbled with lows in the 20 degree F range with a subsequent climb to above normal again. We should all know that it's not safe to plant tender plants during April but because of the warm days it just becomes too tempting to get that summer planting started.
March transitioned out of a cooler than normal February (and January) and gave us a warmer than normal March. That is not to say that there were not a couple of cold blips. The month started with a warm spell. A cold storm came in and knocked temperatures back down well below normal for a couple of days before temperatures ramped back up to near or well above normal with a new record high temperature set on the 15th.
February weather ran backwards. A week-long warm spell started the month but that gave way to below normal temperatures through much of the remainder of the month. Cold air was carried by a series of storms that passed through NM with plenty of wind but little or no moisture - at least not for the Sevilleta area. For average daily temperatures, Feb came in as the 3rd coldest Feb. in the Sev - LTER history - the coldest being 2011 and the 2nd coldest 2004.
The new year seemed to toss us some curves right off the bat. After a record warm 2012, 2013 started off seemingly headed toward the opposite extreme. A couple of southern plunges of the jet stream allowed arctic air to stream into New Mexico for extended periods of time early in January. Night time low temperatures went to new record lows for several days and allowed little rebound for daytime highs.

Well we have weathered the first mighty snow storm of the year actually 2 in one day - a total of 0.2" of snow. It might interest you to know that the National Weather Service (NWS) station at the airport got "no precipitation" on Monday. Actually they reported a trace (<0.01") of precipitation for the day which effectively adds nothing to the totals. Other measurements around Albuquerque by the CoCoRaHS Network showed as much as 0.09". Average January precipitation for Albuquerque is 0.38" - average snowfall is 2.1"
