Spot Weather Forecasts Instructions

General Information

The spot weather forecasts produced by the Division of Forestry are intended for use on prescribed fires and wildfires. These forecasts do not replace the general forecasts produced by the National Weather Service, but are intended to augment their forecasts. Forecasts currently cover the period from 8 a.m. to 8 p.m. The Division of Forestry uses a numerical weather prediction model developed by Penn State University and the National Center for Input FormAtmospheric Research to produce these forecasts.
