Climate of 2005 - February
Wyoming Drought


National Climatic Data Center, 10 March 2005

As noted by the Wyoming State Climatologist (Jan Curtis), February 2005 temperatures were warmer than normal across the eastern two-thirds of the state. Precipitation was below normal over most of the state. A detailed report for February is available at:

The prolonged dryness that Wyoming has been experiencing is having an impact on vegetation. Native cool grass yields forecast by the State Climatologist through the end of June indicate that there will be below normal to nil grasses for livestock grazing throughout most of the state. The growth season for native cool grasses is mid-March to mid-May.
