Dry down over western SD

The prairies of western SD and the southern Black Hills are starting to see the effects of a short-term lack of snowfall. The snow depth has gone to zero in many areas leaving exposed fuels across the landscape.

Listed below are the number of days since the last precipitation event of greater than 0.10" for selected cities. 

Rapid City: 11

Custer: 25

Pine Ridge: 25

Philip: 11

Hot Springs: 25

Buffalo: 53

In January, wildfires across western SD occur with little or no snow pack after a period of several weeks without a wetting precipitation event (greater than 0.10" of liquid equivalent moisture). Above average temperatures and strong winds are also common when big fires do occur. 

The recent dry spell and periodic warm temperatures has taken a toll on the lingering snow. More fuels are now exposed to the dry winter air and are becoming available to carry fire. 

Keep an eye on the forecast and if we see days with strong winds and warmer temperatures, don't be surprised if we do see a few wildfires.
