Weather Notes For 2012
January turned out to be the fourth driest January ever recorded in Crestone since recording keeping was first started in 1982, with the 2.2" of snow recorded also being the fourth least amount of snow to ever fall in the month. By the end of the month downtown Crestone lost it's snowpack for the second January in a row and for only for the third time in the month overall, although the snowpack at our weather station held on - barely.
A record low temperature was tied on Feb 24 at 1ºF. The record was first set in 1996 and also tied in 2010.
A mini duststorm hit for about 10 minutes on Feb 28 with snow on the ground, thanks to the bare, snowless ground out in the valley, where the dust came from. Visibility was down to almost zero during this short event.
On March 7, weather highlights went up for a winter storm watch, then a winter storm warning for the following 24 hours, and then for the third time in a row this winter after a winter highlight was issued, barely a flake of snow ended up falling, as the storm headed down into southern New Mexico. But 3 days later - the very same storm retrograded and headed northwest back into northern New Mexico towards Colorado, and on March 10 we saw snow pellets fall in the afternoon from the very same storm, the snow pellets started off with the temperature at 50ºF. More snow from the storm then fell in the morning hours of March 11.
Whereas the first two months of the year weren't too exciting weather wise, that could not be said for March. Temperature wise, this was the warmest March ever on record, with 6 record highs set on the following days: March 16 - Record high of 66ºF; March 23 - Record high of 68ºF; March 24 - Record high of 69ºF; March 25 - Record high tied at 69 degrees; March 27 - Record high of 67ºF; and on March 31 the high temperature reached 71ºF, not only a record for the date, but this reading becomes the warmest temperature ever recorded in the month of March for Crestone.
March also turned out to be the second driest March on record, and the sixth driest month ever, with only .03 inches of precipitation recorded. The old record for March stands at .02 inches. This March also saw only 0.5 inches of snow fall, the second least amount of snow ever recorded in the month.
Crestone also saw 10 days with humidities below 10% in March including: 7% on March 23, 24, 27, 28, and 29 and 8% readings on March 25 and 26, 30 & 31.
The second dust storm of the year took place on March 18, lasting the entire afternoon, visibility during the storm's peak was down to a few hundred feet. Top wind gust during this storm was 46 MPH, but 4 miles west of the weather station, at the Crestone Charter School's station, the top wind gust was 52 MPH. Then on March 26, another dusty afternoon, with blowing dust bringing the visibility down to one mile at times.
On March 26 the low temperature was 37ºF, a record high low. This was also the first 24 hour period with temperatures above freezing this year and also since October 16, 2011.

April 11 was a day for a few "firsts", including the first rainfall of the year, along with the first two thunderstorms of 2012, one hit in the afternoon with little rain, and the other contained the first hail of '12, along with numerous lighting hits around town. This was also the first time in 4 years that Crestone saw two separate thunderstorms in one day.
Thunder-snowstorm on April 14, then the next day on April 15, a snowfall of 1.3" was a record amount for that date. April 15 had been one of only two April days were no measurable snowfall ever occurred in the month of April. April 27 becomes the lone day now of no measurable snowfall for any April date.
Records are not kept for the warmest temperature at which snow has ever fallen, but if such records were kept, Crestone might had broken that record on April 20. Snow pellets fell that afternoon at 3:40 PM for less than 3 minutes with the temperature at 57ºF. Crestone has seen snow fall several times with the temp around 50ºF, but never with a reading higher than 52ºF. This event is for sure the warmest temperature I personally have ever seen snow fall - anywhere.
After seeing moderate rain and some hail fall on Thursday, April 26, at 11:30PM MST** Thursday the rain changed to heavy snow. Half an inch of snow fell up to midnight, then from 12:01 AM till around 3:00 AM (MST**), another 2.6 inches of snow fell, breaking the record for snowfall on April 27, which had been a trace.
