What a difference a year makes.

Unlike the 2011 growing season in Washington, which was marred by cool weather and frosts, 2012 has been relatively warm without crop-damaging storms, according to a news release.

Overall, temepratures from March through May were average, although they did fluctuate significantly with several periods of hot, summer-like weather.

During the same period in 2011, temperatures remained cool with a lack of heat.

The data is based on information collected by Washington State University's AgWeatherNet system of weather stations.

"Unlike 2011, Mother Nature has for the most part cooperated with WAshington's agricultural interests this year," Gerrit Hoogenboom, AgWeatherNet director, said in the release.

WSU's Prosser Research and Extension Center, for example, logged temperatures 3.3 degrees warmer during the three-month period this year than last.
