Colorado Snowpack

The high frequency of storms this winter has deposited above average snowfall in the Colorado high country.  All of the major river basins in the state have average or above average snow pack up to March 1st.  The central and southern mountains have fared the best with 150% or more of average.  The northern mountains are near average of slightly above.

 http://www.co.nrcs.usda.gov/snow/snow/state/current/monthly/maps_graphs/getsnomap.html

With all of the moisture locked up in the snow, rivers and streams will be flowing high this spring and if the snow melts too fast there could be flooding concerns especially in the southern half of the state.  This will result in an epic year for river rafting and will help to fill our reservoirs.  As we all know much of our water used here along the Front Range comes from the snow pack in the high country.  This is good news for people who have experienced water restrictions in the past and for farmers on the eastern plains where much of the states agriculture is produced.  With a couple more months of winter storms and normal precipitation expected through this spring more snow will be added to what is already a healthy snowpack.  Just because we will have the available water does not mean we should change our habits and use in excess.  Colorado will always be drought prone and with more and more people moving into the state every day the need to conserve still remains.      

Drought Update

Little in the way of meaningful drought across Colorado as of early March, through some dry areas do persist across Eastern Colorado.

The map below shows forecasted temperature deviances for March 2008. As can be seen, much of Colorado is expected to have near normal temperatures for March 2008.

The map below shows forecasted precipitation deviances for March 2008.  Normal precipitation is anticipated across the entire state.

Little change in conditions is anticipated over the next 3 months, with most of the state not expected to see drought conditions.  Extreme southeastern Colorado is anticipated to experience drought conditions persisting and intensifying.

February Summary

February of 2008 was a below average month as far as snowfall and precipitation was concerned.  There were many weak disturbances that moved through, but produced little in the way of snowfall.  With only 5.1" of snow for the month at the Stapleton site and a normal value of 6.3" the month fell 1.2" short of normal.  The first two months of the year have had a precipitation and snowfall deficit.  For the year so far we are behind 0.77" in precipitation and 5.0" below normal in snowfall starting back in October 2007.  As far as temperatures were concerned February 2008 was near normal in average highs and lows with no records broken or tied.  Temperatures ranged from a monthly high of 65 and a monthly low of two resulting in a temperatures spread of 63 degrees.
