May 2011 Outlook

Below are the one-month outlooks for temperature and precipitation for May 2011 created by the Climate Prediction Center. The direct impacts from this winter's La Niña have subsided, however a few residual effects remain, such as higher than normal soil mosture across the northern U.S. This higher than normal soil moisture will likely act to keep temperatures slightly below normal across the northern part of the country, with the opposite effect occuring across the south. The May outlook indicates near normal temperatures and precipitation across much of Wyoming due to a lack of strong climate signals in the central Rockies. Many tools, including numerical models, are used to create these outlooks and a full discussion is available from the Climate Prediction Center here.
