According to the National Integrated Drought Information System (NIDIS), 36% of the state is currently experiencing some level of drought (with 54% being at least abnormally dry). The map featured above shows the drought conditions on January 31.
According to the summary from the latest Colorado Water Conservation Board’s Water Availability Task Force meeting, La Niña looks likely to weaken the rest of winter, with neutral conditions to take over sometime in the spring. The Climate Prediction Center is uncertain about likely temperature patterns as we head into spring and predicts a slight leaning toward drier than average conditions, especially the southern part of the state. However it is uncertain if that will hold true if La Niña is no longer a factor.
