A few other prescribed fires occurred outside of the Flint Hills throughout the week. An area of smoke was analyzed along the Missouri River valley on Tuesday (May 2), primarily aloft, that was likely from prescribed burning in North Dakota and southern Manitoba, Canada. Daily Fires and Smoke Analysis provided by NOAA Hazard Mapping System Fire and Smoke Product are provided on the following pages. KSFIRE.ORG This website was developed as part of the development of the Kansas Flint Hills Smoke Management Plan. Kansas State University hosts the webpage and it includes important information for ranchers and others who might be interested in the Flint Hills, it provides training, regulations, policies, publications, a modeling tool and other links to guide people looking for information on smoke management. The development of the Flint Hills Smoke Management Plan is an attempt to balance the need for prescribed fire in the Flint Hills with the need for dean air in downwind areas. 17cv1906 Sierra Club v.

EPA ED_001523B_00003900-00017 Flint Hills Prescribed Fire Update Upcoming Look at Fires and Smoke Intensive `green-up' has already occurred across the Flint Hills and will likely preclude any additional significant prescribed burning this spring. Temperatures and humidity will be ideal throughout the week ahead. There appears to be a good chance for a round of rain on Wednesday and Thursday. Breezy conditions are expected for Sunday and Monday afternoon. A high pressure moving overhead will drop transport wind speeds below the ideal threshold on Saturday afternoon. Ideal Weather Conditions for Prescribed Burning Current National Weather Service forecast for the approximate center of the Flint Hills showing when conditions may be most favorable for wildland burning as described at KSFire.org. Conditions are most favorable when each parameter has a colored boxplof displayed. Note: Forecast for mixing height and transport winds are only out to 2 days. Forecast valid: 8am May 5, 2017. 17cv1906 Sierra Club v. EPA Friday, May 05, 2017 u 18 ED_001523B_00003900-00018
