Fire Weather Outlooks http://www.spc.noaa.gov/products/fire_wx/index.html
The purpose of the SPC Fire Weather Outlooks and meteorological Risk Categories are to indicate areas where dry dead fuels such as dry grass and dry timber and meteorological conditions (wind, relative humidity, temperature, and dry thunderstorms) might contribute to potentially dangerous wild fire behavior. The SPC does not forecast local meteorological conditions (i.e. local variability of relative humidity or the effects of terrain on wind direction and speed). In addition, slope of local terrain, types of fuels (fuel model), variability of fuels, and live fuel moisture content are not considered in detail.
