How Warm Was It?

With the official start of summer 2012 just around the corner, it is of interest to review just what an unusually warm Spring it has been.  Most of us who were here in Star Valley  appreciated how soon the snow disappeared from the valley floor compared to just last year.  Gardening got off to a very early start with warm weather on many days even in April.

A fellow blogger who also is a meteorology professor at the University of Utah, Jim Steenburgh, recently blogged on how unusually warm it has been nationwide the past 3 months.  I found it quite interesting and want to share through

Here is a link to Jim's blog site

and the following is the post on Jim's blog on this very warm period.

Spring Climate Summary

As many of you have probably seen in the news, it was a very hot spring (March, April, and May) in the contiguous United States.  As reported by the National Climatic Data Center, it was the warmest spring observed in contiguous U.S. since record keeping began in 1895 with an average temperature of 57.1ºF, 5.2ºF higher than the long term (1901–2000) average.  This spring eclipsed the previous warmest spring (1910) by 2.0ºF.  Many states recorded their all-time warmest spring.  Only Oregon and Washington observed near-average temperatures.

The spring statewide average temperature for Utah was the 8th highest on record.  Thus, it was a warm spring in Utah, but not unprecedented.

Records for Salt Lake City go back only to 1948, but show that this was the 2nd warmest spring on record.  Spring of 1992 was warmer, with an average temperature of 57.3ºF compared with 54.8ºF this spring.

The anomalously high spring temperatures on the heels of a dry winter are a primary cause of the high fire danger that exists across Utah and much of the southwest.  

Jim always post very interesting and educational discussions.
