Weather is a critical factor that influences fire behavior. Weather forecasts can be obtained from a number of sources, but the national weather service is a preferred source.  Go to and click on Kansas.  Select a site on the map near the location you plan to burn.  Find the hourly weather forecast.  Good conditions for conducting a prescribed burn and minimizing the impacts of smoke include:

  • 45-70 degrees F temperatures
  • 40-55% relative humidity
  • 5-15 mph winds
  • mixing height >1800 feet
  • 30-50% cloud cover.

Next, check out the website and use the smoke dispersion model to determine where your smoke will go.  Click on the icon titled “Click Here to Access Smoke Model” to access the smoke model (Figure 1).

A color coded map showing the cumulative effects of burning in the Flint Hills area will appear (Figure 2). Green means small impact, yellow medium impact, and red large impact of smoke from burning on major cities. To determine the direction of the smoke, select “Your Fire Impacts”, followed by the county, fuel load, size (acres to burn), and date. The model will give a smoke plume over a 48-hour period. The smoke model only predicts where the smoke is likely to travel.  It does not mean environmental conditions are safe to burn.

Temperature inversions, which occur primarily in the late afternoon, at night, and in the early morning can also impact smoke dispersal. Consult the Kansas Mesonet at to determine the likelihood of a temperature inversion. The site indicates temperatures at 2 and 10 meters as well as wind speed and direction for various reporting stations.

Prescribed burning is an essential tool for maintaining the integrity of our prairies in Kansas. Plan well, burn safely, and remember smoke from your fire can have negative impacts downwind.
