...CRITICAL FIRE WEATHER CONDITIONS THURSDAY AND FRIDAY... .Southerly winds with gusts around 40 to 45 mph are expected tomorrow ahead of an approaching front. Relative humidity values will fall to 25 to 30 percent across portions of Minnesota during the afternoon. A Red Flag Warning has been issued for western Minnesota. Any small amount of moisture increase associated with the front will be short lived as northwest winds bring lower dew points back into Minnesota and Wisconsin Friday. Temperatures Friday are forecast to be in the 80s area wide, leading to RH values falling below 20 percent. The winds are not expected to be quite as strong as Thursday, so have maintained a Fire Weather Watch for now. * AFFECTED AREA...Polk, Barron, and Rusk. * TIMING...From Friday afternoon through Friday evening. * WINDS...West winds 10 to 15 mph with gusts up to 25 mph. * RELATIVE HUMIDITY...Around 20 percent. * IMPACTS...Any fires that develop will spread rapidly. Outdoor burning is not recommended.
A Fire Weather Watch means that critical fire weather conditions are possible during the valid watch time. These conditions could promote the rapid spread of wildfires which could become life-threatening. Check for forecast updates and a possible upgrade of this watch to a Red Flag Warning.
